Started on program counter
I've started working on the program counter. The sockets for the EEPROMs and the parallel load counters are all soldered in. I then prototyped the counters on my breadboard and all was well, but after soldering them up, there seems to be a short somewhere. The board is pulling almost 100mA @ 12v. To make matters worse, I blew the fuse in my multimeter while looking for the short. So...not a whole lot of progress this weekend. Once I get a new fuse, I'll keep hunting for that short. Could also be two outputs connected. Lots of pins to check. Pics of the new board to be posted soon.
