Builds keep crashing. Now down to the BARE machine with the instruction set.
Rebuilding hardware with revised bypass capacitors, and new IC's.
A revised ALU card, runs the 99,999 bottles of beer program in about 24 hours
with no problem. I plan to build a duplicate set of cards for more testing.
Perhaps in time I will have a spare machine to give to a good home.
Ben.

Still have noise problems, so it just works on lucky days.I need to revise the display panel
and other PCB's so will be testing more when I get boards in.While waiting for that I hope
to have a 13x10x6.5 inch wooden box, modified to hold the computer.

Redesigned the motherboard,now 4 layer and I hope better bus termination.
Have to wait now for that PCB.
