<img src="/media/history/images/timeline_11-77_s100_1.jpg"/> <br/><br/> <p>In this end of year 1977, when a computer fanatic wished to build himself a powerful and evolutional computer, he'd only have pactically one choice: to purchase a S-100 Bus based system, assembled or in kit form.<br/> Several manufacturers were selling spare parts allowing to assemble progressively and at low cost a basic system. <br/><br/> The first step consisted in acquiring a box with a power supply and a bus card.<br/> One had to choose then amongst several CPU cards available: Motorola 6800, MOS 6502, Intel 8080 and 8085 or Zilog Z80. The cards were provided assembled or in kit form. One had then to solder the components on the card.<br/> A third essential part, the RAM card. It was composed of 2 to 64 Kb of static or dynamic memory chip. <br/><br/> At this stage, the computer was able to operate... providing that one could communicate with it! A teletype or video terminal plugged in the computer's serial port was then necessary.<br/> After a few days of operation, the user noticed that he would most probably need to buy a backup system to save his programs. For a few hundred $ more, he would rapidly buy a card punch or a cassette recorder with the additional interface card. <br/><br/> Though his computer was working correctly and that our fanatic already spent approximately $1500, he's not yet acquainted that he'll have to spend approximately twice the price in the next months to purchase more memory, communication cards, one or two floppy drives, a printer, a modem... <br/><br/> In 1977, when one would like to acquire a real computer, one had to be passionate, very handy... and rich! <br/><br/> </p><img src="/media/history/images/timeline_11-77_s100_2.jpg"/>
