Leon's test rom's flashes get faster and faster and then it crashes. It happens in less than a minute. Seems to be slower if I give it some time between tries.

Board on the bench would not boot. 7404 at IC7 was smoking hot, so I replaced that and leon's would boot. Ram test was sad about the 5101 at IC19, replaced, still read bad. The 7408 at IC12 was bad, replaced, ram tested good. Started to continue testing but then the speed up problem started happening. Tried no ram and a different 6808 to no avail.

I'll get it jumpered up for Andre's next, but wanted to see if anyone has seen something like this or had any ideas.

Before drifting off to sleep last night I was all "ooh maybe the crystal section". I've got one and the caps on the way. I only have a logic probe, perhaps it's time to start looking at scopes. Thank you so much for your help! I will be back with results.

After replacing the crystal and two caps, the behavior continued. Upon reflection it did not start until I replaced the 7408 in the memory protect circuit to get the 5101 going. I had cannibalized it off a sys 6 board, and ordered a few 74f08's to replace. I threw a new 74f08 in on a whim and the behavior disappeared. I have no idea.

I tried both chips with Marco's test chip and it was not influenced differently.

What a great program! It was a joy to use. Thanks for your hard work!
