The first draft of the BMOW schematics are finished, along with complete equation lists for the 11 unique GALs (18 GALs total). This is everything needed to actually build the machine. You can view it all on the technical info page, along with an updated block diagram.

Whew, what a job that was! The datasheets, the timing diagrams, the insomnia… I’m really beginning to question my own sanity. If some of the schematics seem a little confusing and convoluted, it’s probably because I was asleep while I drew them. Ditto for the spaghetti wire paths.

I’m going to step back now and review the whole system, looking for any blunders I’ve made, or any opportunities for improvement. I hope that the people who’ve been following my progress can find some time to review the plans as well. Your design feedback is welcome and appreciated!
