fails, but that means reverse engineering the module level detail
(or, more precisely, constructing a functionally equivalent set of
module level details). I keep hoping that some day the missing
details will be found. Similarly, there are some other details that
are missing; the PPU wire lists predate the central/monitor exchange
jump feature so that too would have to be reconstructed from less
detailed information.
Wasn't CEJ/MEJ a field-installable ECO? Maybe there's paper on that
somewhere.
ECS to me would be the real bugger, since it isn't just a box of core
sitting off to the side. On the Cybers, didn't it also include the ILR?
That was too many years ago. I do remember that it made the business
of RCH/DCH much simpler in PPRES--no need to go through MTR.
Well, when you're done with the 6600, you can work up a STAR 100 :) I'm
not aware of even a software emulator being available for that one.
