I sent a mail to Al at aek at bitsavers.org on 4/11 regarding a bunch of IBM
manuals.

Never heard back so they went into the trash. These manuals are decades
older so I don't want to trash them.
If Al jumps in here, fine. He can get them. Otherwise, based on timing, Bob
gets them.

Hello friends,
I recently acquired a NIB 9-track for use in my (someday to be operational) PDP-11/23+ or PDP-11/73 (I've lost track of the details). I got it on ebay for $150 but the shipping from CA to NY was not insubstantial :). The ebay ad showed a well-used unit but when it arrived it was clearly new in box! Nice when that happens :) Some pix:

It is VERY heavy! Took me and my 17 year old (and a lot of sweat and swearing) to get it up to the attic where my burgeoning little vintage computing lab is shaping up.
I should mention, I'd like this tape drive to be able to work in either the various DEC OS's available (RT-11/RSX/others?) and also Unix/BSD which I plan (hope) to get up and running.
Now for some questions.
1. I've been told the QT13 is a very good card to interface here. I've been looking for a while on ebay without luck. I do see a QT14 on ebay right now at a good price, but I am not familiar with the "S" card business and what that means for use in a PDP-11 backplane.
2. Anyone have a QT13 for sale? Or based on my dec and unix interests, is there a better/recommended card?
3. Anyone have the 50 pin cables/connectors available? If not I feel confident I could make these up. But I thought I'd ask in case someone has a set getting in their way
4. Anyone ever make a pertec to USB project? Might be interesting to get access to old tapes on more modern computers?
Thanks all!

Hi,
I have a stack of a few dozen CD-ROM disks with various files (old
software, backup files, photos). I'm willing to pay a reasonable rate
to have somebody read each of these in, convert them to .ISO files or
some other reasonable format, and either make them downloadable or
put them on a thumb drive.
Does anybody know of such a service? I can find lots of services for
converting audio CD's into MP3 files, but nothing that specifically
handles data CD-ROMs.
Any leads most appreciated. Please reply directly, as I don't often
check this list.
Thanks,
jp
One of my few remaining Holy Grail items, I got a Hayes Transet 1000
this week. My three-part Hayes stack is now complete.
I've scanned the manual and quick-ref card. The scan is not up to the
quality of my usual work, as I tried a new technique using a DSLR
instead of a scanner so I wouldn't have to take the manual apart. The
results are good enough to read, but that's about it. I'll re-do it
again someday with the proper tools. Here's the link:

I have two manuals for the config software (alas only the Mac version
of the software itself), which I'll try to do soon. I'll image the
Mac disk as well. If anyone has the PC version of the software, I'd
love it have it.

I have two Silent 700 terminals (model 745) that I bought quite a few years
ago (nonworking). Couldn't find a schematic. Last week I just happened to
search for one - and found a complete service manual with theory of
operation and full schematics! So I got them on the workbench.
The more worn one wouldn't print anything on the paper but was otherwise
working. I found that the nylon printhead pressure adjustment wheel had
split and fallen off the solenoid shaft into the case, along with the
pressure spring. Then it would print, but I promptly discovered that the
printhead has several "dots" missing in a pattern that could not be
accounted for by the driver circuitry. I confirmed it by swapping the
printhead from the other one, and now it prints perfectly. So at least I
have one working now :)
The second one in half-duplex mode will only beep (Ctrl-G), CR and LF in
half-duplex mode, so I know the keyboard is alive and there is power.
But it otherwise won't move the carriage forwards (including space), or
print any characters at all.
Before I go to the trouble of diagnosis and repair, does anyone have a good
printhead, or know where I can find one?
No point in fixing it if the characters won't be printing properly when I'm
done...
thanks

Still cleaning out for Nevada move.

Last 2 are interesting. 2075 Processing Unit and some Russian machine
EC4001. Number sounds familiar from my eBay sojourns.
Available for cost of Media Mail shipping. These buggers are heavy. As last
time, all or nothing.

Anyone know much about early MIPS workstations? I'm trying to get a
MIPS RS2030 to boot, without much luck so far. It goes through the
selftest but stops with the internal LED display at "5" accompanied by a
continuous beep.
Known problems:
- The Dallas DS1287 battery is flat; I can hack a 3V lithium onto that.
I assume it should still work to some extent even if the contents are lost?
- The RAM is highly suspect. I think it needs a minimum of 8MB to start
up. It has a good complement of SIPPs, but some of them are definitely
non-original and are actually 30-pin SIMMs that somebody has done a
rubbish job of soldering short stiff wires onto.
So I'd like to know what the RAM spec really is, whether I need to
reprogram the Dallas chip (and if so what goes where), and what the
diagnostic numbers on the internal LED mean. Anyone?
