Sean –
The chips you have go in the following locations:
U16,U18,U20,U22,U24,U26,U28,U30 on the left-hand side of the board.
U55-U62 on the right-hand side of the board.
Make sure all the notches line up properly with the board diagrams.
Jumpers:
For 4 megs, it's J1-Closed, J2-Open.
I don't know how legal it is for me to warp up the RamTest disk, but if
people say it's OK I'll do it.
