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.

Hello all,
I have transferred some simh .tap files to my PDP-11/23+ running RSX11M+.
There I have tried to use VCP to attach them to a virtual device but I keep
getting an invalid record format error. I then realized the simh .tap files
most likely aren't organized correctly. If I attach them to TS0 in simh I
can work with them. So now I am trying duplicate a tape into a new .tap
file created using VCP. I can't for the life of me get it to work though.
BRU doesn't support tape-to-tape and FLX doesn't complain but also never
completes. Is there a process for tape duplication under RSX?
The images were first transferred to my PiDP-11 using ftp in binary mode
over TCP/IP. From there I used NFT in image mode and I tried both record
and block modes.
I have also seen the simh tape tools but there doesn't seem to be a tool to
convert a simh file back to what would be on a real tape.
Anyone have any information or pointers to get this to work?
Thanks!

Does anyone know anything about the key lock on the mains on/off
switch of the P3800?
I have one without a key. I can't identify the lock manufacturer (no
markings on it at all) so I've not been able to get a blank to cut a
replacement key. A friend who is a locksmith said she'd never seen
anything like it.
Any ideas who made the lock itself?
Were all P3800 machines normally 'keyed alike' If so, a copy of an
existing key (anyone have one?) would be a great help.
Yes, I can trvially bypass the lock/switch mechanically or
electrically. But I want to try to get this thing as original as
possible.

I saw on the BASIC Programming group on FaceBook that a new venture is going to start publishing Compute's Gazette again.

Perhaps interesting to some of you.

This past Saturday at a local retro meetup, it was announced there was
still at least 1 open spot for a speaker/presentation at VCF SW (Dallas)
this June.
Just passing the word, if anyone is in the area at that time and interested
to speak on a topic vintage-computing related. There should be a signup
at the VCF SW page.
Been messing around with a GRiD system recently - I'm not seeing a solid
archive of things like PDFs and ROMs for that system. And I've heard a
rumor there used to be one, but it went offline a few years back?
Mostly I'm looking for GPIB related info, and maybe either native GRiD
drivers or some compatible MS-DOS drivers to use the GPIB port on that
system.
Here some images and reference info of what I've learned so far about a
late-model (but before Tandy) GRiD system...

I'm also hunting around for one of those GRiD disk drives, if there is any
spare standalone one not bundled with another existing system.
