Subj: REPLY TO MSG #5973 (SURVEY - ROM FOR FILE RECOVERY)

Thanks for the ROM cost Rick, they're a bit less than I expected. Other ROM
attached is no problem because a cold-start has just occurred, so: pull out
other ROM, push in recovery ROM and recover, then remove it and push in
original ROM. ExtRAM is not problem either if the memory keep alive power and
WR leads (added for ExtRAM) are considered in the recovery ROM.  Make sure
these two "pins" are open on the ROMBO/ROM interconnect. I had considered ports
(except the BCR) but then we're talking "loadin' code into RAM" and we need all
of the RAM unchanged so that recovery code (not in RAM) can study it and do the
recovery.
