PK88

Single-board computer based on KM1810VM88 CPU (Ukrainian clone of Intel 8088) that can run ELKS!

PK stands for Персональний Комп'ютер ("Personalnii Kompyuter", i.e. "Personal Computer") in Ukrainian.

This board runs @ 8 MHz (24 MHz oscillator) in minimum mode.

• KiCad schematics
• GAL sources - Address & I/O port decoders using 2x ATF16V8
• Various circuit simulations - made with Digital
• MetalBIOS - IBM PC XT compatible-ish BIOS that I made specifically for PK-88
