We can but hope that the DRAMs are actually OK and that the problems lie elsewhere. After all, they were OK on Colin's against all expectations, in spite of the rest of that machine turning out to be a chip graveyard.

If not, someone has at least done Tim the prior favour of socketing nearly all of the DRAMs and furthermore, we know that the hardware, even with all of that rough looking soldering on the DRAM sockets and the track repairs around the not-socketed IC, did work, if only for one run.

But we're running ahead again. Repair the power rails first.
