Be glad you don't have to deal with this kind of thing:

A bunch of PDP 8 system tapes. That were literally soaking in liquid water when recovered.
Yes, that is mildew. They are nearly dried out now.
Still to be determined if they can be manually teased apart intact enough to be read.
After deciphering what they all are, from remnants of the labels and a paper list that
was with them.
Hopefully these are already online somewhere. If not, then a lot of work to recover.
The DEC mag tapes... sigh. Still not even thinking about them. Just slow drying.

I came across an Allen-Bradley 1771-DMC4 Control Coprocessor. If you are
familiar with AB PLC's, it is a 1771-IO chassis module that could be a
"sidecar" for a PLC5 PLC or a standalone module.
It runs some version of OS-9/68k on a 68340 processor. It has 4MB static
ram and a 10MB ethernet AUI connector. I hooked up a terminal and can get
to an OS-9 prompt. It has by default a 64k RAM disk that is empty. The best
I can gather is that there was an external IDE (AB 1771-PCB PCbridge) that
was used to create programs that were loaded onto the RAM disk. Once
configured it would run standalone.
Microware is still around in some form so OS-9 is not completely dead and I
did find some references to a Microware product called PBbridge. It would
be interesting to experiment with.
I am curious if anyone has any experience with this hardware, with the IDE
or OS-9/68k in general. I've never seen much discussion of OS-9/68k on
classicmp.
Hi all.
I was wondering if there are any good online resources on reading for the
purpose of archiving 8-bit papertapes of unknown origin. I have been
reading tapes as text and also as binary, 8/n/1 thinking that's going to
capture everything. I load into a hex editor, and if necessary convert to
octal.
I am wondering if there any persons who have a systematic process they'd
like to share for this kind of work. I will share the tapes I have with the
community, but there is no point if I am not doing it right.
Thanks

My neighbor has an empty DEC Alpha server cabinet she'd be happy to give
up, for free.
It's a 2100 series, model 5/250. She's in Durham, NC. Anybody interested?

Once you've put your soul at ease regarding use of pakgen, and found a
copy, and built it (it is a C program), you might find the following
repository streamlines the process of application.

I was looking for an old post on comp.lang.forth, and was surprised to discover that the group doesn't appear to be hosted on google groups any more.? Searching the group pulls up a "banned group" message, and selecting the "continue to the group" button shows 0 messages in the group.? This appears to be due to spam showing up in the unmoderated group.
Google bought Dejanews years ago, and, as I understand, was the defacto main usenet repository.? Is is all really gone, or just temporarily hidden?? How long ago did this happen?? Is the full comp.lang.forth archive available anywhere? ?
I wonder if it's time to set up some NNTP mirrors and gather as much historical usenet content as possible.? Much of the overall content is garbage, but there's some priceless stuff in there, and even more that will become interesting in light of future developments.

I've got a Morrow Microdecision 3 on the bench and gather it often
shipped with the MD-60 terminal, but for the life of me I can't find
what emulation that terminal uses.
Lacking the native terminal, what emulation should I be using?
Thanks!

Greetings. It has been an interesting day. Rather late in the day, a buddy
notified me of a local thrift store that went under, and mentioned there
may be some computers on site up for grabs. Upon arrival, the place was a
mess, but the folks there were friendly and gave me the tour, everything
had to go, the shopkeeper skipped town and left the place full of junk for
the Building owner to clean out.
I found a TRS 80 Model 12, a vga commodore branded monitor, commodore
cassette drive, among some misc 5.25 floppy disks. There may be more, I
need to go back for another sweep in the morning.
The computer is extremely big, taking up an entire kitchen table,rivaling
the space that is taken up on my desk for a pdp 11. I am looking to clear a
space to work on it without dropping parts.
The machine looks to be clean, However i am missing the keyboard.
The machine does not power on or show anything on the screen. I do hear a
high pitched hiss, so there may be some kind of power supply issue. I was
not aware of this model of machine, I am curious if anyone has a spare
keyboard for sale.
I am not familiar with this model, it has 2, 8 inch floppy drives on the
front. I am curious about the format of the disks, would it be possible to
use another computer with an 8 inch drive to make a floppy to start the
machine, or do the drives use an odd difficult format that would be
impossible to write?

I'm trying to copy files off my Otrona Attache 8:16 using FastLynx 3.3, but I keep getting an error 708 when trying to push SL.EXE to the Otrona over the serial port. I am wondering if the reason for the error is that the Otrona does not have a C: drive. Therefore, I would like to try to use Assign.com to assign C: to A:, but the Attache version of MS-DOS 2.11 does not include Assign.com. Does anyone have a copy of the MS-DOS 2.11 version of Assign.com they can send me?
Thanks,
Robert Feldman
