This was a very interesting project. I wire wrapped something like your Version 1.0 board and I found a few errors in the 1.0 schematic around the 6268. the I/O's should be 1-4: 15,14,13,12 and the /WE_OPx should be pin 11. Are these the only issues?

Also, I could not get SQR or D to work in the CALC.ASM code. Was there an update to the code, this may have been mentioned in your blog? Thanks!
