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.
