REV 3 - REV 5 - The beginning (ST536)

Just a little note that that location would make it impossible to fit on a 520ST board.

I don't have a ST I can look at visually, can you take one when you get chance please.

The problem I believe, is there are failing bank of 8 bits , all just happen to be on the longest tracks.. Which just so happen to hit the PLD and IDE as well. The tracks need to be shorter which is nearon impossible. Moving the ROM would help a bit, but thats not simple either.

Got it. See images here. The front of the board needs to be as flat as possible to fit under the keyboard.

Though if the board extended to the right a bit, it wouldn't get in the way of anything ?

In this machine, no. Anything that adds height needs to be further back though to avoid the keyboard

Though looks like you have the headers in there ? they would be higher than the ROM most likely.

I will remove the headers once we're stable so the case can close.
