There have been a few versions of the utility imd2raw.c floating around
that will take Dave Dunfield's ImageDisk-created images (i.e. an .IMD file)
and make a linear binary image devoid of any metadata. This is similar to
the function of Dave's IMDU.COM program's /b switch.
I've corrected a problem with the assumption that all imd2raw.c descendants
to date have made: sectors that have a skew (i.e. not 1-1 interleaved)
weren't linearized correctly. The skewed sectors need to be written out in
"sorted" order, which is not necessarily captured/physical order. This is
easily verified by comparing output from "IMDU /b" to earlier imd2raw
outputs on any .IMD that has a sector skew that isn't 1, 2, 3 [...].
It's up on github here:

Hello,
I'm an employee with the National radio astronomy observatory here in Socorro New Mexico.
As part of our NGVLA upgrades, we are seeking to get rid of old data tapes from the tape reel days of Computing. These contain things such as the boot loaders, OS, specific collection programs and antenna movement programs.
I personally would hate to see these just wind up in the literal dumpster and would like to see them sent out to a museum or an archiving body that can preserve them and keep them safe as a dynamic part of history.
If anyone is interested or knows someone who would be interested in the VLAs data tape library please let me know.

Well, I've got the Greaseweazle software to run, but I don't know why,
which is hardly encouraging.
Installing various Windows updates, downloading .dlls, and puting the
latter in various directories changed the error messages but it never
actually worked. But downloading the latest Greaseweazle software did,
it ran first time. So no idea what I was doing wrong (maybe 32 bit
.vs. 64 bit Windows applications?)
I can now get the list of commands when I run gw.exe. And can get help
on them using the -h option. I've not tried connecting a drive yet,
but the software can find and talk to the board (the green 'activity'
LED turns on). For example 'gw rpm' which is used to check the drive
speed by timing the index pulses times out and gives a 'no index'
error which seems entrely reasonable.
However I am not sure if I'll be able to use it. There is one very
important thing missing : DOCUMENTATION. The 'wikii' on github is
ridiculously incomplete. There is no user manual or man pages. The
software source in python (a language I've never used) has very few
comments and is not clear at all.
It's not clear to me exactly what all the options are for, and when to use them.

Hi all,
I just came across pictures on the LCM website about their SDS Sigma installation there.
On the pictures, one can see 10-platter disk packs in the corner and stored on the disk drives.
Did the LCM ever had these in operation, either for data retrieval or even demo purposes?
I know of the Jim Austin Computer museum where they fixed a CDC 9766 drive but it suffered
a head crash after a few hours according to their description which led to giving up the operation
of these drives.
Greetings,
Pierre

Chris,
I would be interested in getting a copy of the SSPS/X software for POS. I have a manual for SPSS/11 and would love to try to get the software running under RSX11M+ if possible.
Thanks,
Mark

Starting to go through my boxes of POS stuff. I know of course that 3.2
is out there (minus the Pro/Communications option which has a bad disk
in the distro) however are these disks out there now?
Pro/Venix 1.0 on floppies
POS V2.0a on floppies
POS version 1.5 (with test diskette, maintenance application, a thing
called Pro/Pre labelled "Diskette system", system overview and
instruction disks)
POS V1.7 (I have that here somewhere)
Pro/Basic Version 1.0 and 1.2
SPSS/X For Professional (this is a really interesting one, anyone heard
of this?)
If so let me know and I won't copy them. If not I'll go over to the
mighty Deskpro/XE and start sucking the data off for archives....
Thanks!
Chris

I want to buy an old computer from a guy I don’t know in Houston (I’ll pay shipping to CA), but it’s a lot of money, and I don’t want to lose it - what are my options?
Thanks-
Steve.
Be aware that clicking on a malicious url can result on malware or spyware being installed on your machine without any further action on your part. All browsers have vulnerabilities. The most famous of these was the older version of Pegasus by NSO back in the 2014-2016 timeframe. These so called 1-click exploits are well known to bad actors. It’s a continuous cat and mouse game between exploit writers and infosec. For the interested, look at this report regarding Apple and the “Trident” series of exploits from 2016.

P.S. Exploits have evolved considerably since Trident and now include 0-click exploits. See Google’s Project Zero for instance.
