I found a VT50 print set in the heaps and recognized there were no copy on
bitsavers so I ran it through a scanner.

Compared to the VT52 print set that is online this one contain plenty of
manufacturing information f
nice find...

Absolutely. I have a Documation M200, Calcomp drumplotter and a DEC vector
screen that would be nice to interface. My PDP-8/L has a BA08 expansion box

Hi all,
I continued my investigations about the power supply if the 8406 subsystem.
Here is what I observe:
With the PSU in charge, I mean with a disk drive connected but without
the +24V :
+5V -5V +12V -12V: OK
If I connect the +24V to the drive this is at this moment than the power
supply g
So based on this entire thread I should probably hunt down some Shugart 850s to
be safe.

Hi List
Well I think I've found why the RX01 is not responding.
The device address (75) is not getting decoded on the controller because
the CPU does not assert BUS I/O PAUSE L
Which it should do I think when it sees an IO instruction.
Do I have this right?

It works very well. I've dumped several hundred 5" drives with it
which resulted in added support for many different controllers in

I've got the Cromemco WDI and WDI-II S100 controllers for both the 8" 7xxx

He has been working on a Flip Chip tester for a couple of years now and has
been using a bread boarded early version of this for several years.
