Hi all,
My 11/73 restoration has got to the point that I am loading stuff from
RT11 backups, and I have a lot of Saturn-calc and wp data that I would
like to see again. My licensed copy and the manual are long gone!
I downloaded some RX02 images posted by Mark Matlock, but the disks
appear to be all zeroes where I expect the directory to be.
Does anybody know of a source?
cheers,
Nigel

Is it possible the images are 'physical' disk images rather than
'logical'
disk images and have
sector interleaving applied? That can cause things to appear in odd places.

I think I have TSX/RX02 versions of Saturn stuff out there already.
Where is it....
Ah here: https://www.crystel.com/pdp/
Wow, I have a dsm11 disk image there too? Weird. And the XT Tool kit
guide (prior to when it was called the Pro/350).
Let me know if those contain anything interesting.

I have some DEC format 8 inch floppies from the mid 1980's that may have
Saturn WP on it. It rings a bell, I think I had a copy at one time.
Long, long time ago. I can't read the floppies (got no drive), anyone
in the Wash DC area that can read them would help.

Well, I'm located south of Baltimore and have been doing pdp11's for
about 30 years now. Currently I have running and tested the following
equipment:
11/83 with ESDI, TK70, RL02, and RX02 drives
11/23+ with RQDX3, TK50, RX50 drives
11/24 with 1mb of memory and an RL11 controller
2 pdp8/L's fully operational, no peripherals.
11/05, 16kw memory, RX11
Professional/380 with RD53, DECNA, and RX50's.
PDT11/150 that works (fun but not too useful)
One of Dave Gesswin's MFM emulators and a pile of RD50-54 drives
One of those Gotek floppy things flashed for RX50 support
I can reconfigure one of the RL02's to be an RL01 for read only if needed.
So if you need media checked out I can give it a go. Somewhere I have an
HP SCSI 9 track drive that could be pressed into service and one of
these days I'll fix and test the CDC 9457 Lark drives.
