OK, so where should a thing like this go:
Anybody got a decent place to upload that? it's my notes on the MS650-AA,
and more generally the KA650 CMCTL memory subsystem.
Includes my theory of operation of the CMCTL, the organization of memory,
the ECC equations (kinda, the info is there to derive them), explanations
of the signals on the memory bus, and most importantly, a list of which
bits and RAM regions correspond to the 312 DRAMs on the board.
