Spectravideon oma suunnittelutiimi oli vastuussa SVI-728:n teknisestä toteutuksesta. Yhtiö käytti hyväkseen aiempien tuotteidensa teknologioita ja mukautti niitä MSX-vaatimuksiin.

Kuten aluksi mainittiin, niin Spectravideo SVI-728 oli suosittu erityisesti Suomessa, jossa se löysi tiensä moniin koteihin ja kouluihin. Myyntilukuja ei ole tarkasti dokumentoitu, mutta SVI-728 oli yksi Suomen myydyimmistä MSX-tietokoneista, osin sen hyvän saatavuuden ja kilpailukykyisen hinnoittelun ansiosta. Lisäksi sitä mainostettiin huomattavasti enemmän kuin muita MSX-standardin tietokoneita ainakin Suomessa, havainnon voi tehdä lukemalla esimerkiksi Printti- ja Mikrobitti-lehtiä vuosilta 1985-1986. Spectravideo SVI-728 oli saatavilla useista elektroniikkaliikkeistä, kuten Tekniset-ketjusta ja paikallisista kodinkoneliikkeistä. SVI-728:n julkaisuajankohdan hinta oli Suomessa noin 2 500–3 000 markkaa. Hinta teki siitä edullisemman vaihtoehdon monille kilpailijoille, kuten Commodore 64:lle, joka oli kalliimpi. Spectravideo-paketit sisälsivät usein myös lisälaitteita, kuten kasettiaseman tai peliohjaimen, mikä lisäsi houkuttelevuutta. Myynti painottui Eurooppaan ja erityisesti Pohjoismaihin, mutta sitä myytiin myös Japanissa, missä MSX-standardi oli erityisen suosittu. Yhdysvalloissa MSX-standardin menestys jäi rajalliseksi, joten SVI-728:kin jäi siellä marginaali-ilmiöksi.

MSX-alustalla oli laaja ohjelmistovalikoima, ja SVI-728 oli yhteensopiva kaikkien MSX-standardin ohjelmistojen kanssa.

1. Knightmare: Toimintapeli, jossa pelaaja ohjasi pahaa vastaan taistelevaa sankaria.
2. Metal Gear: Taktinen toimintapeli, josta myöhemmin kehittyi yksi pelihistorian merkittävimmistä pelisarjoista.
3. Penguin Adventure: Klassinen tasohyppelypeli, jossa pelaaja ohjasi pingviiniä eri maailmoissa.
4. Kings Valley: Ongelmanratkaisupeli, jossa pelaajan tehtävänä oli ratkaista monimutkaisia tasoja.
5. Yie Ar Kung-Fu: aikaansa edellä oleva karatapeli vuodelta 1985. Oli saatavana myös muille kotimikroille, kuten Commodorelle ja Spectrumille.

Pelien lisäksi MSX-standardi mahdollisti monipuolisen ohjelmoinnin. BASIC-ohjelmointikielen sisällyttäminen laski ohjelmoinnin oppimisen kynnystä.

The home computer legend of the 1980’s

Released in 1982, the Commodore 64 quickly became one of the most iconic home computers of the 1980s, a machine that combined affordability, technical innovation, and a rich software ecosystem to dominate the personal computing market. Developed by Commodore International, the C64 was designed to outcompete rivals like the Sinclair ZX Spectrum, Atari 8-bit series, and Texas Instruments machines by offering a perfect blend of power, flexibility, and cost-effectiveness. Its technical specifications were impressive for the time: a MOS Technology 6510 CPU running at 1 MHz, 64 KB of RAM—hence the name “C64”—and advanced graphics and sound capabilities unmatched by most competitors. These features made it not only a tool for productivity and education but also a revolutionary platform for gaming, multimedia, and digital creativity.

One of the key innovations of the Commodore 64 was its graphic and sound hardware. The VIC-II graphics chip allowed a resolution of 320×200 pixels with 16 colors, hardware sprites, smooth scrolling, and support for multiple display modes. Its SID sound chip offered three-channel synthesizer audio with filters and waveforms, enabling music and sound effects that rivaled professional synthesizers of the era. These capabilities made the C64 the preferred platform for game developers, and titles like The Last Ninja, Impossible Mission, and Elite demonstrated the machine’s technical prowess. In fact, many developers regarded the C64 as a system that enabled creativity within the constraints of 8-bit computing, encouraging innovative programming techniques and complex gameplay designs. The Commodore 64 was also revolutionary for its software ecosystem. Unlike many contemporary machines that relied on proprietary or limited software, the C64 quickly amassed a vast library of games, productivity applications, and educational titles. Cartridge, cassette, and later disk-based media allowed users to access a diverse range of software, while the built-in BASIC interpreter enabled custom programming. This made the C64 appealing not only to gamers but also to hobbyists and students eager to learn programming, experiment with digital art, or manage personal data. Its affordability—often priced below $600 at launch—made it accessible to households and schools, which further cemented its role as a cornerstone of 1980s home computing.

The impact of the Commodore 64 on gaming culture cannot be overstated. Its superior graphics and audio capabilities, combined with an extensive developer community, led to the creation of many genres and franchises that remain influential today. It became a training ground for early video game developers and composers, fostering a generation of talent that would later shape the international gaming industry. The C64 also popularized home gaming in Europe and North America, demonstrating that personal computers could rival dedicated gaming consoles in entertainment value, while offering the added benefit of programming and customization. Beyond gaming, the C64 influenced educational and professional computing. Schools adopted the machine for teaching programming and computer literacy, while home users employed it for word processing, spreadsheets, and even amateur music production. Peripherals such as disk drives, printers, modems, and networking devices expanded its capabilities, bridging the gap between hobbyist experimentation and practical computing. The machine’s compatibility with a wide range of software and hardware ensured longevity, allowing users to continue developing skills and enjoying content years after its release.

Despite its many strengths, the Commodore 64 was not without limitations. Its single-channel CPU, while adequate for most tasks, constrained multitasking and processing speed compared to later systems. Its BASIC environment, while flexible, was slower and less sophisticated than the environments offered by some competitors. Additionally, the machine relied heavily on tape and disk-based media, which could be slow and prone to errors, and its 8-bit architecture ultimately limited the graphical and computational ceiling. Yet these limitations did little to diminish its popularity; on the contrary, they often inspired creative programming solutions and innovative software design. The market success of the C64 was extraordinary. Over its lifetime, Commodore sold an estimated 17 million units worldwide, making it one of the best-selling single personal computer models in history. Its dominance shaped the competitive landscape, forcing companies like Atari, Sinclair, and Texas Instruments to reconsider pricing, features, and marketing strategies. The machine’s combination of affordability, power, and software diversity created a virtuous cycle: more users attracted more developers, which in turn attracted more users, solidifying the C64 as a cultural and technological icon.

Culturally, the Commodore 64 left an indelible mark. It influenced not only computing literacy but also music, design, and digital creativity. Iconic chiptunes created on the SID chip inspired future generations of electronic musicians, while early demos and graphics pushed the boundaries of what 8-bit computers could achieve. Communities of enthusiasts, hobbyists, and coders formed around the C64, fostering collaboration, knowledge sharing, and innovation. Its legacy is evident in modern retro computing, emulation projects, and the nostalgia-driven revival of 1980s computing culture. In conclusion, the Commodore 64 was a transformative machine that redefined home computing. Its technical innovations, extensive software library, and affordability allowed it to dominate the market, influence culture, and inspire generations of developers. While it faced limitations inherent to 8-bit architecture, its strengths far outweighed its weaknesses. The C64 demonstrated that a single machine could excel as both a gaming console and a computational platform, bridging entertainment and education in ways few machines had done before. Its impact on technology, industry, and culture remains profound, solidifying its place as one of the most important personal computers of all time.

Bridging Innovation Across Europe

Released in the early 1980s, the Apple II Europlus represented Apple’s commitment to expanding its highly successful Apple II line into European markets. While the original Apple II series had already established itself as a powerful and versatile home computer in the United States, the Europlus model was designed specifically to meet the needs of European consumers, incorporating region-specific modifications such as local keyboard layouts, voltage compatibility, and television standards. It was part of a broader strategy by Apple to maintain its dominance in the personal computer market while adapting to the diverse technical and cultural requirements of international users. At its core, the Apple II Europlus shared the same robust architecture as its predecessors. Powered by a MOS Technology 6502 CPU running at 1 MHz, it featured expandable RAM, a color display, and high-resolution graphics capabilities for its time. The machine came with AppleSoft BASIC built into ROM, enabling users to write programs, manage data, or run the growing library of software that had made the Apple II so popular. Its open architecture allowed for peripheral expansion, including disk drives, printers, modems, and interface cards, which extended the system’s utility far beyond a mere home computer. These features combined to make the Europlus both a learning tool and a platform for professional productivity.

One of the most significant aspects of the Apple II Europlus was its role in education. Across Europe, schools adopted the machine as part of early computing programs, teaching students the fundamentals of programming, logic, and problem-solving. Its BASIC interpreter made it accessible to young learners, while more advanced students could explore hardware expansion and assembly-level programming. The Apple II Europlus also supported a wide range of educational software, from mathematics drills to language learning programs, fostering computational literacy in a generation that would later shape the European technology landscape.

Gaming was another key strength of the Apple II Europlus. Although not as graphically or sonically advanced as some contemporaries like the Commodore 64 or Atari 8-bit computers, it nevertheless hosted a vibrant library of titles. Games such as Castle Wolfenstein, Lode Runner, and various text-based adventures offered engaging experiences that appealed to both casual and dedicated users. Because of its open architecture, hobbyists and developers could create their own software, leading to a proliferation of small-scale games and utilities that enriched the platform and encouraged creativity among users.

The Apple II Europlus also played a pivotal role in professional and creative applications. It was employed for word processing, spreadsheets, and database management, particularly in small businesses and educational institutions. Peripheral support allowed for printing, networking, and data storage on floppy disks, which extended the system’s usefulness well beyond the classroom or living room. Its combination of versatility, expandability, and reliability made it a practical choice for users who needed a machine capable of handling both recreational and professional tasks.

Despite its strengths, the Apple II Europlus had its limitations. Its graphics, while impressive for text and simple color displays, could not compete with the high-resolution capabilities of some contemporaries, such as the Commodore 64 or Atari 800XL. Sound was limited to basic beeps and tones, lacking the richness found in dedicated audio chips on rival machines. Additionally, its price point remained higher than some competing European models, which occasionally hindered its adoption among cost-conscious consumers and contributed to the rise of other 8-bit platforms in the region.

Nevertheless, the Apple II Europlus’s cultural and educational impact was significant. It served as many European students’ first introduction to computing, providing them with the tools to experiment, program, and explore technology independently. Its presence helped solidify Apple’s reputation as a reliable and innovative computer manufacturer, while its adaptability to local markets demonstrated foresight in international strategy. Moreover, the Europlus contributed to the broader European home computing ecosystem, inspiring developers, hobbyists, and educators alike.

Today, the Apple II Europlus is remembered as part of the legacy of the Apple II family, a line of computers that defined the early era of personal computing. Collectors and retro computing enthusiasts continue to celebrate its role in bringing computing to European homes and schools, preserving software and hardware for posterity. While it may not have been as universally popular as some of its competitors, the Europlus remains a symbol of accessibility, versatility, and the early globalization of personal computing—a machine that empowered a generation to explore the possibilities of technology.

Ikoninen tietokone 1970-luvulta

Vuoden 1977 alussa henkilökohtaisten tietokoneiden markkinat olivat vasta alkutaipaleella. Sitä ei vielä tiedetty silloin, että tästä tulisi valtavat mittasuhteet omaava teollisuudenala. Tuona vuonna julkaistiin kolme konetta, joita nykyään pidetään usein kotitietokoneiden/henkilökohtaisten tietokoneiden aikakauden edelläkävijöinä: Apple II kesäkuussa 1977 (Apple Computer Inc.) ja TRS-80 (Tandy Corporation Radio Shack -tuotemerkillä) elokuussa/syyskuussa 1977. Noin samaan aikaan ilmestyi myös eräs tärkeä kone: Commodore PET, joka myöhemmin tunnettiin tuotemerkkisyistä Euroopassa Commodore 30- tai 40-alkuisilla numerosarjoilla (esim. 3016, 4032).

Vuosi 1977: Apple II ja TRS-80

Kesäkuussa 1977 Apple esitteli Apple II:n, jonka oli suunnitellut Steve Wozniak ja jonka markkinoinnista vastasivat Steve Jobs ja yritys. Muutamaa kuukautta myöhemmin, 3. elokuuta 1977, Radio Shack julkisti TRS-80 Model I:n; myynti alkoi syyskuussa ja ylitti nopeasti alkuperäiset odotukset. Nämä koneet luokitellaan usein yhdessä Commodore PET:n kanssa varhaisten koti-/henkilökohtaisten mikrotietokoneiden ”vuoden 1977 kolmikoksi”. Tuo vuosi merkitsi käännekohtaa: harrastussarjoista ja teollisuus-/mikro-ohjainjärjestelmistä siirryttiin suoraan koulutukseen, kotiin ja pienyrityksiin markkinoitaviin koneisiin.

Commodore PET (jonka nimi virallisesti oli ”Personal Electronic Transactor”) oli Commodore Internationalin valmistama tietokone. Useiden lähteiden mukaan PET:n kehitys alkoi vuonna 1976, ja se esiteltiin ensimmäisen kerran julkisesti tammikuussa 1977 Chicagossa pidetyssä Winter Consumer Electronics Show (CES) -messuilla. PET toimitettiin ensimmäisille asiakkaille myöhemmin vuonna 1977. Monien lähteiden mukaan ensimmäiset sata yksikköä toimitettiin lokakuun puolivälissä 1977, mutta yleinen kuluttajamyynti alkoi vasta joulukuussa 1977. Näin ollen PET oli markkinoilla samoihin aikoihin julkistetun Apple II:n ja TRS-80:n kanssa. PET perustui MOS Technology 6502 -mikroprosessoriin, jonka kellotaajuus oli noin 1 MHz. PET-sarjaan kuului sisäänrakennettu näyttö (alun perin 9 tuuman yksivärinen näyttö) ja näppäimistö, ja varhaisissa malleissa oli integroitu kasettisoitin tallennustilaa varten. Commodore PET:n kotelo oli hitsattu metallirunko, mikä auttoi muovaamaan PET:n erottuvan all-in-one-kotelon muotoilun.

Vuoden 1977–1978 näkökulmasta PET oli yksi harvoista täysin henkilökohtaisista tietokoneista: kun sen kytki pistorasiaan ja käynnisti, siinä oli näppäimistö, näyttö, BASIC-tulkki ja tallennustila (kasetti). Täydellisen BASIC-tulkki ROM-muistissa sekä I/O-portit ja laajennusliitännät tekivät PET:stä vaihtoehdon koulutukseen, pienyrityksille, harrastajien ohjelmointiin ja tutkimukseen. Sen integroidun suunnittelun ansiosta PET oli houkutteleva vaihtoehto käyttäjille, jotka halusivat oppia ohjelmointia, kehittää yksinkertaisia sovelluksia tai jopa tutkia tietokonegrafiikkaa. Lisäksi, koska sen oli valmistanut Commodore – yritys, jolla oli jo kokemusta laskimista ja teollisuuselektroniikasta – se oli jonkin verran viimeistellympi ja enemmän käyttövalmis ratkaisu kuin aikaisempina vuosina ilmestyneet rakennusarjoihin perustuneet tietokonemallit kuten Apple I esimerkiksi. Erityisesti oppilaitoksissa PET löysi asiakkaita sisäänrakennetun näytön ja näppäimistön sekä vankan metallikotelon ansiosta, sillä se kesti kovaa käyttöä luokkahuoneissa. Pienyrityksissä PET:n IEEE-488 (GPIB-tyyppinen) rinnakkaisportti (myöhemmissä malleissa) mahdollisti oheislaitteiden, kuten levyasemien ja tulostimien käytön. Se teki siitä sopivan tietojenkäsittelyyn, kuten vaikkapa taloushallinon sovelluksiin tai prosessien automatisointiin, joka ei ennen ollut mahdollista tehdä ilman tietokonetta yhtä tehokkaasti.

Käyttäjät saattoivat haluta PET-tietokoneen oppiakseen ohjelmoimaan BASIC- tai konekielellä valmiilla tietokoneella, käyttääkseen ohjelmistoja (esim. liiketoiminnan laskentataulukoita, tekstinkäsittelyohjelmia, oppimisohjelmistoja), käyttääkseen sitä luokkahuoneessa tai laboratorioympäristössä opetustietokoneena ja integroidakseen sen oheislaitteisiin ja tietojen tallennukseen. Lyhyesti sanottuna, PET oli yksi ensimmäisistä koneista, joka muutti ”pöytätietokoneen” idean harrastajien piirilevystä kaupasta ostettavaksi tuotteeksi, jonka voi hankkia ja käyttää ilman että tietokonetta pitäisi kasata osista. Commodore PET oli valmis tuote, joka sisälsi kaiken tarvittavan käyttövalmiina.

PET:tä koskevissa aikakauden arvosteluissa ja kommenteissa arvostettiin sen innovatiivisuutta mutta myös kritiikkiä laite sai osakseen. Kysynnän ja kustannusrajoitteiden vuoksi hinta nousi aluksi nopeasti. Koneen integroitua suunnittelua ja käyttövalmiutta kehuttiin. Arvostelijat huomauttivat kuitenkin myös, että varhaisissa malleissa oli niin sanottu ”chiclet”-näppäimistö (pienet kumimaiset näppäimet, jotka muistuttivat purukumia ”Chiclets”), jota monet käyttäjät pitivät hankalana näppäillä. Pieni sisäänrakennettu näyttö (9 tuumaa) ja yksivärinen näyttö nähtiin joskus vähäisiksi verrattuna myöhempiin koneisiin, mutta tuolloin ne olivat hyväksyttäviä, kun otettiin huomioon hinta ja koko tietokoneen uutuus yhdessä laitteessa. PET:stä todettiin myös, että sen käyttäjät pystyivät kirjoittamaan omia ohjelmia BASIC-kielellä, mutta monet valittivat pienestä näppäimistöstä. Toisaalta PET oli täysin integroitu paketti (prosessori, näyttö, näppäimistö, tallennustila), se teki siitä paljon käyttäjäystävällisemmän kuin monet muut tuon aikakauden mikrotietokoneet. Se myös loi pohjan sille, miltä kotitietokone tai pienyrityksen tietokone voisi näyttää.

Microsoft Corporationin (ja sen perustajan Bill Gatesin) rooli PET:n historiassa liittyy BASIC-tulkkiohjelmaan: PET käytti Microsoftin 6502-pohjaisen BASIC-tulkkiohjelman muunnosta. Lähteiden mukaan Commodore lisensoi Microsoftin 6502 BASICin; Microsoft toimitti lähdekoodin 6502 BASICille (BASIC-80:n portti) ja Commodore mukautti sen (lisäämällä aloitusnäytön, kehotteet, I/O-tuen, SYS-komennon ja korjaamalla virheitä). Tietojemme mukaan jos kirjoittaa komennon WAIT6502,1 PET-tietokoneeseen, jossa on BASIC V2, näytön vasempaan yläkulmaan ilmestyy teksti ”MICROSOFT!” – jonka Bill Gates itse lisäsi riidan jälkeen Commodoren perustajan Jack Tramielin kanssa vahvistaakseen, että BASIC oli peräisin Microsoftilta. Microsoftin osallistuminen auttoi siis nopeuttamaan PET:n toimittamista korkealaatuisella BASIC-tulkilla, mikä vähensi yhtä tietokonevalmistajien suurimmista rasitteista tuolloin (eli kielellisen ympäristön luomista).

Jack Tramielin johtama Commodore osti BASIC-tulkin Microsoftilta kertamaksulla 25 000 dollaria, mikä oli Commodorelle hyvä kauppa, sillä kymmeniä miljoonia Commodore-tietokoneita myytiin Microsoftin ohjelma mukana kertamaksulla. Bill Gates päätti lopettaa ohjelmien myynnin tietokonevalmistajille ja myydä sen sijaan ohjelmistolisenssejä. Kuten hyvin tiedetään, IBM lisensoi Microsoftin käyttöjärjestelmän IBM PC:lle, mikä johti siihen, että Microsoftista tuli yksi maailman arvokkaimmista yrityksistä. Commodore ei kyennyt toistamaan 1980-luvulla saavuttamaansa menestystä, mutta Microsoftin lisenssipohjainen liiketoimintamalli mahdollisti kenelle tahansa yhteensopivan käyttöjärjestelmän sisältävän PC:n valmistamisen. Tämä osoittautui kohtalokkaaksi muille tietokonevalmistajille. Ainoastaan Apple selvisi, ja sekin tarvitsi Microsoftin apua 1990-luvulla.

PET-laitteiden myynti ylitti 200 000 kappaletta maailmanlaajuisesti (kaikki PET-mallit yhteensä) ennen seb tuotannon lopettamista. Joissakin lähteissä esitetään pienempiä lukuja tai arvioita (esimerkiksi yli 50 000 kappaletta), Täyttä varmuutta asiasta ei ole. Tuotanto lopetettiin noin vuonna 1982. Siihen mennessä tehokkaampien järjestelmien (mukaan lukien Commodoren omat myöhemmät koneet) kilpailu ja PET-all-in-one-muodon kysynnän lasku saivat Commodoren siirtymään eteenpäin. PET:n asema koulutusmarkkinoilla pysyi vahvana vielä jonkin aikaa, mutta lopulta alusta korvattiin Apple II ja IBM PC-yhteensopivilla malleilla.

Historiallisesta näkökulmasta Commodore PET on merkittävä, koska se oli yksi ensimmäisistä henkilökohtaisista tietokoneista, joita markkinoitiin massoille. Se oli samoihin aikoihin markkinoilla Apple II:n ja TRS-80:n kanssa vuonna 1977. Sen integroidussa kotelossa oli näppäimistö, näyttö ja tallennustila. Commodore PET yksinkertaisti tietokoneen käyttöä opettajille, harrastajille ja pienyritysten käyttäjille. Tämä malli tuli myöhemmin normiksi henkilökohtaisissa tietokoneissa. MOS 6502 -prosessorin käyttö, BASIC-kielen integrointi ROM-muistiin ja laajennusporttien sisällyttäminen tekivät siitä joustavan alustan. Microsoftin BASIC-tulkki ja sen mukauttaminen tietokoneeseen oli myös esimerkki varhaisista ohjelmisto-laitteistokumppanuuksista, joista tuli standardi mikrotietokonealalla. PET-sarja loi myös pohjan Commodoren myöhemmälle menestykselle (kuten kuuluisalle Commodore 64:lle vuonna 1982) ja auttoi henkilökohtaisten tietokoneiden laitteistojen yleistymisessä. Vuosina 1977 tai 1978 PET-tietokoneen ostaminen oli järkevää, jos oli kiinnostunut ohjelmoinnista tai tarvitsi valmiiksi koottua tietokonetta eikä rakennussarjaa. Commodore tarjosi tietokoneen, jonka takana oli tunnettu valmistaja. PET oli jotain, mitä monet muut tuon ajan mikrotietokoneet eivät tarjonneet tällaisessa all-in-one-paketissa.
