Are all the adresses, A0-A11, on the all memory chips used? If it was
engineered for more than 16 RAM and they simply tied one or more addresses
low while the others are high you might be able to get more memory by making
all addresses high but I assume the CPU does the multiplexing of all the
memory addresses as per the spec sheet.
I've looked at the chip last year but never followed through on the specs
and pinouts, if you want to look at the memory chip it can be found at:
http://bwrc.eecs.berkeley.edu/Research/Intercom_Group/details/hardware/strongarmdocs.html
just download the TC51V16165CFTS-60 Toshiba EDO DRAM Data Sheet (pdf, 1.68
MB)
Do we have pinouts on the CPU chip? Someone out there must have a schematic
or service manual.
