Very nice, Tom. I've been using the old build to test the Ab cards; maybe it's time to upgrade
(BTW, I suck at the game.) Does it still fit in 512K?
For those of you asking about cards, get together and make a plan. The circuit layout is dead easy, getting the physical boards made isn't too expensive, and the EPROM chips are about $5 each (you need parallel ones). Find people who can solder small chips, and a few folks with eeprom programmers (yes, I have one), and we could do it. Just need someone to oversee it all.
Tom: Sorry to hear about the concussion. I'm like that when I don't get enough sleep. Here's hoping work doesn't interfere quite so much until you get done with this
Keep up the good work. We're rooting for your.
Saw your post on the ipl palette problems. I had to laugh at that - it's almost as bad as the one in the irq routine [save A,X,Y and restore them. But not the flags register? What if the irq occurs in the middle of a cmp / branch pair? ]
