Building the best homebrew computer ever

September 8th, 2012, 23:34 Posted By: wraggster

A few days ago when I posted a homebrew Motorola 68000 computer spectacular, I briefly mentioned a truly spectacular homebrew computer built by [Simon Ferber]. When I posted a link to a Youtube demo of his 68k board, he was working on a website to document the architecture design, hardware, and software. That website is now up (cache if you need it) and now we can all get a good look at the best homebrew computer ever built.
Built around the 68008 CPU – slightly less capable than the 68000 found in the original Macs, Amigas, and the TI-89 – [Simon]‘s Kiwi computer has peripherals out the wazoo. A Yamaha V9990 Video Display Processor provides a 640×480 display with 32k colors. Two SID chips taken from a Commodore 64 provide stereo chiptune audio, and a floppy disk controller, IDE/ATA bus, and CS8900A Ethernet controller provide all the practical functionality you’d expect from an awesome computer.
On the software side of things, [Simon] is running Enhanced Basic 68k, but of course he can’t just use BASIC to fiddle around with all the cool chips on the Kiwi. With that in mind, he came up with a C-based toolchain that included porting libc to the Kiwi.
Like any good homebrew computer project, all the schematics, a bit of code, and a BOM are provided. [Simon] is currently working on (slightly) redesigning the PCB layout of the Kiwi, and we’ll be happy to see those files released. Anyone up for a Kiwi PCB group buy?
