OggCamp 13: Forking Hardware!
Last updated: 19 Oct 2013 - 09:31
This year at OggCamp I presented on using version control to manage hardware projects. It's something I think will be really important as the barrier to spinning a new hardware design gets lower and lower. Below are the slides from the talk I did.
Z80 Project Updates and Revision Control

It's been a (very) long time since the last update to this project. I've been busy on loads of new stuff for the project. The system is now capable of booting a binary from SD card or USB memory stick formatted in either FAT16 or FAT32. There's also full PS/2 keyboard support, a much more sophisticated interrupt control mechanism and a VGA display now.
I'm planning to go through all these new features and write-up how I've got there but for now I'm just going to do a summary. Since my last update, I have built a basic chassis to contain the growing number of boards and hold all the connectors, there's a new connector board which has the USB host sockets, an SD card slot, PS/2 keyboard connector a composite video output connector and a 3.3V and 5V power supply. This connects up to the original pair of boards providing power and two LEDs (one is driven by the PIC as a "hard disk light" when accessing the SD, the other is driven by a transistor from the Z80's HALT line), the 5-pin
