Yours seems to have TTY in slot 13 and there are 5 IO
slots (15-
11) as on the original 1602 (1602B has got more due to the re-
duced number of PCBs in the CPU). The CPI controlling the panel in
your case is at the very end opposite to the power supply and
inbetween you have got two core stacks - in total 32kW I think.
A 1602B can hold 64kW of memory (only accessible via a banking
function proprietary to Rolm, so not usable e.g. for RDOS).
I thought the 16xx did it the same way Keronix and DCC did it -- by
limiting indirection to one level and then using the high order bit for
address rather than indicating indirection?
Have you ever powered on your 1666 with the 1648
panel? Although
the 1666 was quite popular in the US I think the non US customers
preferred the MSE14 due to better compatibility with the DG Eclipse
series...
IIRC we sold a bunch of 1666Bs to the US Navy in YUK/something
nomenclature).
Cheers,
Chris
