I'm trying to id this system I just rescued last
month.? It is an Eclipse of some type.

Not sure what sales model it is?? ie? C330 or C130 or
???
Given that it was embedded in a CAT scanner it's likely a S series, not
a C series (scientific vs. commercial, the latter having the commercial
instruction set extensions to better support COBOL). Typically it would
be a S/130, but the 16 slot chassis might make it a S/230. The legend
on the CPU1 board (the bottom-most in the chassis) may give you a hint;
CPU2 is the same for both the S/130 and S/230, so it's of no use it
trying to sort this out.
The options listed are for I/O controllers. Off the top of my head, 4010
is EIA teletype; 4042 is an oddball, it's the data channel logic
sub-option for the 4040 general purpose interface. 4192 doesn't
immediately ring a bell; I'll have to dig that up when I have a moment.
The front panel is trashed, so what are the
differences? between the front panels fromother models.
Are there any manuals for this out there ??
They're not terribly interchangeable across models. Does the trashed
panel have LEDs or incandescent bulbs? IIRC the S/130 was the only
model that used LEDs from the factory.
The back plane has 2 damaged chips.? one has a? 74S133
which i understand the other has 20a.?if I read it right.? looks to be a hex inverter of
some type ??
Does it have a DG logo on it? If so, BitSavers may have the component
guide (and if not, I have a copy around here somewhere).
Good luck!
Cheers,
Chris
