Sorry: I goofed and sent the message to the list (too many different
MUAs and I forget their defaults...)
I have a set of four manuals for the Digivue 512-60 plasma display
screen as from at least one version of a Plato terminal (with
rear-projection capability.) They match the unit I have which was from
'broken' Plato terminal of some kind - all I got was the keyboard and
display - no power supplies. The unit looked like it had been 'drop
tested' but the display was intact. Never fired it up, but did talk to
an engineer at Corning (who supplied the manuals) and was told that
power supply sequencing was "very" critical.
I have this notion I sent a copy of these to AK to add to bitsavers, but
it was some time ago. I had two professionally photocopied copies made
and seem to have only one left - hoping the other is with Al. If not, I
can make more: the originals are still around somewhere.
If there is interest, I'll make an effort to get a copy to to AK but
given his workload, I hate to add to the pile... He's already done me a
number of favours getting some of my old stuff onto bitsavers and I hate
to be a bother...
FYI I have no capability of doing any sort of 'quality' scanning myself.

It would be great to get those scanned. It seems that documentation of the O-I
display devices and related power supplies is quite rare, so it would be good
to make sure whatever is available gets collected.
I have power supply documentation (copies), will try to get those scanned.

I found the manuals for my unit, but it appears older than yours - perhaps one
of the original units.
The hardware manual describes the model "512-60 DIGIVUE display/memory unit,
D141."
The electrical connections are .1 inch dual-row edge-connector style; 60 pins for
data/control (half are grounds) and 30 pins for power. The connectors are described as
"Amp Twin Leaf Printed Circuit Edge Connectors."
However, it does have copious schematics, so you may get some use from it.
I should be mailing it out by this weekend.

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 power supply and a 25-pin for
everything else.
Love to know what the interface specs are so I can make the display do
something interesting. Schematics would also be nice. Anyone have any docs
stashed away?
Thanks,
Josh
