Firstly, are the 9825 and 9845 processors the same
part?
I have a 9845 which is on the 'to be investigated' list. I will hopefully
be pulling it to bits (non-destructively) soon. I've not done much on it
yet, but from what I remember there are 2 processors in there.
One is a metal-heatsinked hybrid. It looks a lot like the one in the
9825, but I don't even know if the pinout is the same, let alone the
microcoding. The other is a set of 3 boards called the 'Sandwich'
according to one of the lables on the chassis. There are 4 40 pin chips
(which I will lay odds are 2901s), some microcode PROMs, and lots of
smaller chips.
