Here are a couple of links to homebrew cpu and computers that I thought my readers might finder interesting. The first is a homebrew CPU that I found on Hacked Gadgets. The Nibbler is a 4-bit CPU, hence the name (a nibble is half a byte).
The second link is a 3-chip retrocomputer via Hack A Day. It uses a 6502 CPU, much like the early Apple computers. I wonder if something similar could be done for the beloved 6809, as used in the Tandy CoCo…
I love all the action going on in homebrew computing. Kinda reminds me of the early days. And here’s another one, using nothing by NAND gates.
I don’t know how I missed it, but this has to be the greatest homebrew computer ever! Some of the features:
- MC68008 CPU, clocked with 10MHz
- 4MB DRAM, 512kB dedicated VRAM
- Yamaha V9990 Video Display Processor
- dual SID stereo
- IDE/ATA and floppy disk interface
- 10base-T Ethernet
- PS/2 compatible Keyboard and Mouse ports
- Two Atari style Joystick ports
- RS232 and parallel ports
- 32KB EPROM with IDE/ATA Boot Code
- Enhanced Basic 68k
