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:
http://w2hx.com/x/VintageComp/Fujitsu-2444AC/
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!

A Fujitsu M2444AC in new condition is a great tape drive if you want
to work with 9-track 1/2-inch tapes, and don't need 800BPI, and plan
to use it with a host with a Pertec interface, and have the space to
set it up and someone to help you move a 200 pound drive into place.
You have to manually thread the tape when you load it, but I actually
consider that a plus as it is one less thing to go wrong compared to
an auto loading tape drive.
I currently have a couple of them that I have used with Q-Bus systems.
I agree with the recommendation to use an Emulex QT13 interface. That
is what I have used in TMSCP mode to install 2.11BSD and RSTS/E 10.1
from tape on an 11/73 system. I also have one or more
Dilog
DQ130/132/140/142 Pertec interfaces (I forget what the models are,
some don't have manuals on Bitsavers). Those aren't quite as friendly
to set up and use as the QT13.
I'd have to look and see how many QT13 cards I have. Probably more
than two for the two M2444AC drives I have. I just built cables
myself. I have a 3M Scotchflex 3640 press which makes it easy to press
the IDC connectors on to the cable. I bought a full 100-foot roll of
3M 1700/50 or 3365/50 cable for a reasonable price on eBay.

Question to owners of the 2444AC. I have been looking to acquire the Emulex QT13 but
cannot find anything on ebay (I did miss one early on and wanted to kick myself). Anyone
have one available for purchase?
Second question. The cable that I need to make here. Can anyone confirm I need to female
IDC connectors on each side? (the tape drive and the QT13 have male pins)?
Thanks

That reminds me I need to check to see how many QT13 boards I
currently have and see if I have one to spare.
This picture shows the SUN configuration female D-shell connectors
with ribbon cables running to the two 50-pin Pertec interface
connectors on the cache controller board:
http://w2hx.com/x/VintageComp/Fujitsu-2444AC/0306192310.jpg
If you remove those 'A' and 'B' ribbon cables then you just need a
pair of 50-pin cables with female IDC connectors on one side, and if
you are using a QT13 then female IDC connectors on the other side as
well.
You need to check the connector pinout tables in the 2444AC manual
against the QT13 manual to see which connector on the 2444AC goes to
which connector on the QT13 so you don't get the cables crossed. I
forget without checking the manuals myself.

Great, thank you to everyone!
This is what I purchased...
https://www.ebay.com/itm/171171330190
looks to be the right thing. I would have made it myself but I'd have to buy like 50
feet minimum of the ribbon plus connectors plus shipping plus my time. This seemed like a
good compromise.

Hi Eugene,
I found my Emulex boards, but found TU13s and not QT13s. I did not look at
the S box boards.
Then I found a few Cipher Data Products ( AKA Spectra Logic Products)
500A00s. I'm not sure what they are, but they look like re-branded Emulex
with different handles.
Did Dilog or anyone else make anything else that would work?

I got a great pair of cables for this project.
50 conductor, 50 pin IDC, 10 feet long.

Cost was $35 all in for the pair of 10' cables. Not bad considering 50 pin ribbon
isn't cheap plus connectors plus time.

Expensive if purchased new stock, but since SS has gone through a couple
of corporate acquisitions, you can sometimes find it on the surplus
market under its old Eltra brand for considerable savings. Odd that
Eltra also once owned Converse shoes...
I"ve got a big spool of the stuff in my parts cabinet that will probably
outlast me. Purchased surplus with the box water-damaged somewhat,
which didn't affect the spool inside.
The bigger problem is finding really decent IDC connectors--so much of
the stuff nowadays is of Chinese clone manufacture and not very good.
I'll go out of my way to pick up NOS T&B Ansley IDCs.
But plain old flat straight ribbon cable in a 10" length will do for the
2444; even at 6250, frequencies aren't much higher than 1MHz.

Sounds like I might be ok. Except mine are 10 feet not inches! I guess I'll just have
to try them out.
Thanks everyone!

Several years ago, I made a simple Pertec interface ISA card using 3

The pertec-to-SD project sounds very cool. Keep me in
mind if you need testers/buyers.
Yes, me too! I still have a working 92185 (Keystone) drive,
and could be interested if your design is not too expensive.
Thanks,

I have some Pertec formatters - but shipping over the pond would be
prohibitive? They are in unknown condition, and likely need work. I'd
have to look up their capabilities - I seem to recall at least one of
them was for a 7 track drive (or maybe 7/9 drive). A couple of them
hosted a mouse one year, but were subsequently cleaned up:

I'm still looking for the schematics for this drive.
Unlike many other Fujitsu storage products, the schematics aren't
included in the service manual.
It's possible they were 11x17
