From the project
Motorola 68010 based sbc with IDE, keyboard, DMA, PIT, Xosera & more!
This isn't my first or (hopefully)last Retro style computer system, I alredy made two 6502 based computers, 8088 based system that is IBM compatable with 8 bit ISA, and built and coded for a handfull of z80/z180 based systems, mostly two RC2014 (Its funny that i like z80 MUCH more than 6502 but never made a system araund z80). And also have ZX Spectrum 48k and ZX Spectrum NEXT.
