Bringing retro 8080 retro computer on Stellaris Launchpad

Some people have passion on building old gear simulators on modern hardware. Some of you may remember old BASIC machines that run on 8080 processors. If you look at hardware specs – they were really scarce: 1k of user RAM, 1k of display RAM, 8k for BASIC ROM and 2k of monitor ROM. Simply speaking almost any modern microcontroller can house such parameters inside memory and have more than enough of processing power. jscrane have built an emulator for this machine on Stellaris Launchpad. Launchpad has 16k of RAM which was divided in two parts – 12k for main memory and 2k for the display. It has plenty of flash (256k) where all ROMs can be placed. Simulator supports 30 lines of 40 characters on a display, which is a… Continue reading
