Nice find but still later than Mar 1989.
Since Compuadd didn’t make drives it does raise the question of whose drives
were in there.

Hi all --
I find myself with an Owens Illinois Digivue plasma display, model
designation MDXVI. This appears to be a later model than the ones used
in the PLATO IV and V terminals and I can't find any real information on
it. This one has two D-sub connectors on the rear -- a 15-pin for the

I'm looking for the schematic of a Tektronix 4050E01 ROM expander
(toaster). This is the one that works with either the
Tektronix 4051 or 4052/4054 units. Different than the 4051E01. I have a
few to fix. Anyone have a manual for one that they
could scan?
Thanks,
Bob

Unfortunately there is no documentation to support Pete's recollection - if
there is any I would like to see it.
For example:

Sorry for the typo, I typed 6 where I should have typed 9, as in 1969 when I

You're probably right, but the work is so massive, and also this time I
would like to understand and target this breakdown instead of working
(as usual) in blind mode.
In addition, I do not see the same type of capacitor on the CPU board as

Yes. I think there were royalties to pay for a true SCSI

Yes indeed, on the "Peripheral Interface" connector of the US
configuration there was a terminator which seems indicated that nothing
was connected there. Moreover, with the Program Cartridge US, the
terminal does not recognize the PERIPHERAL I/O board of my original
configuration.
This is why
