I've just finished cleaning up and checking the schematics for my 6502 computer. I've uploaded them to my website, just in case anyone wants to take a look. URLs are:
CPU card : http://www.philpem.dsl.pipex.com/6502comp/6502cpu.tif
UART card: http://www.philpem.dsl.pipex.com/6502comp/6502uart.tif
The files are Group 4 TIFF format - the AlternaTIFF plugin should be able to view them, as should any decent image viewer (*cough* IrfanView *cough*).
I'm open to constructive criticism - if you think I've done something very stupid, or if you like the design, please let me know
Kudos to Lee Davison for his 6502 CPU card design - my CPU card is a modified version of his 6502 CPU card (well, there are only so many ways to design a 6502-based CPU card
) - I added the DIN41612 bus connector and the diagnostic display. The plan is to have the firmware run a quick systems check on bootup, displaying the binary ID of the current test on the diag display. If there's an error, the CPU halts with the last test ID on the display, thus making it that little bit easier to debug Later.
