I think I may have a user manual somewhere, but alas no schematics.
This is part of a Tektronix development system. There's another unit, the
same size, that contains options like a logic analyser, EPROM programmer,
In-Circuit Emulator, etc.
I used it quite a bit to debug an 80186 based 3270/SNA card for PCs and had
all the manuals but I never saw any schematics. At that time I was young
and unexperienced and didn't collect much stuff ;-)
I have picked
one up because it based on a LSI-11/2 (M7270) and it
reminds me of my first job in Olivetti many years ago.
Yes, it's a real DEC CPU card with Tektronix peripheral cards. The
backplane has one Q-bus connector at one end for the CPU and non-DEC edge
connectors for all the other cards. IIRC, these units either had 2 Qume 8" floppy
drives or one floppy drive
and a Micropolis 1203 hard disk with the Micropolis controller board on top.
Mine is the 2 Qume floppy type. Never saw the one with the HD, but I remember
reding it ran some type of Unix.
Mine, alas, is not easy to get to, or I'd pull the
covers and have a look
at the PSU for you. If you get no other help, you might just convince me
to have a look.
I called Tek in Italy and the didn't even know what I was talking about 8-(.
