Hi all,
I tried several ways to get a working SCSI image to be successfully boote
on a ZULU 2024 SCSI Emulator.
1. I do have an Image of an RZ25-E drive containing RSX11M Plus, which is

after approx 30 years of waiting our time has come to get hands on a Cyber

These systems as other systems before are using 400Hz psus.
One approach would be to use a 50Hz/400Hz power converter. There are ones on
the market creating almost pure sinus output with minimal harmon
Hi all,
Once I visited LCM some years ago I was allowed to visit their repair
laboratory.
I was introduced to an approach to substitute DEC BA11 PSU modules by modern
DC-DC converter modules.
They used a 3D printed plastic chassis to mount the converter, electrolytic as

Hi all,
I do see a lot of CDC documentation on bitsavers like software, hardware
concepts, programming concepts, but no logic diagrams, schematics, detailed
assembly etc.
Didn't publish CDC logic diagrams, schematic, board layouts etc, esp. of

Maybe there are someone on this list, formerly employed at or involved in
CHM who saved the STL or design files of this chassis substitute?

Hello All,
I got a CDC 152 Logic Card Tester.
This one does have some kind of a patch panel to configure the cordwood module
test procedure.
I did not find any reference to this unit as well as documentation while
querying the internet.
Any hints to docs?

But the problem with privately operated sites could be, that they might vanish
at some point.
