speaking of memory tests, I found a fully populated ms11 board in
(horrible) storage, complete with freaking MOUSE DROPPINGS. I just cleaned
it really well with electronics cleaner spray and a hard toothbrush, dried
it thoroughly, installed and and ran ?msd?? for like 15 passes. TOTALLY
FLAWLESS, 0 errors. These machines are amazing sometimes. It's like the
volkswagen bug of computing. (and this is with my good 11/34 board set
that is not exhibiting the mysterious zero errors).

In addition, many manuals for specific devices or CPUs actually have
