2026 Retrocomputing Challenge: A Homebrew Computer In Only Three ICs
First reported Source: HackadayLast editorial activity
What happened
Yes, three: the 68008, an SRAM chip, and a PIC microcontroller that acts as the ROM. Software is provided by the suitably-retro CP/M68K, or standalone executables, which run on both hardware configurations.
The “lite” option restricts you to a maximum of 512 KB of RAM and a single serial port, but it looks like you still get I2C and the option to plug in an SD “hard drive” or RTC module however you configure the machine. Through the serial port, you can of course connect a terminal of you choice, or even use a thermal printer. The “full” version has two serial ports, if you want to do both.
