Thanks Denys, I managed to find information on this project on several other sites, one thing that was asked in one of the articles was the speed of this board the same as that of the chip, the answer was 1/20th I think this is due to propagation delay in the wiring or tracks. having things on a single wafer of silicon helps

Interesting video, I would like to see one on the indirect jump bug with low byte 0xff, and of course the famous indexed Y mode that outputs a spurious address during the instruction, that Woz utilized in his floppy disk controller.
The designers of the WDC65C02 fixed the indexed Y mode addressing bug, and couldn't figure out why the apple floppy disk controller didn't work.
