No, don't say excellant condition, just
say unknown condition. That way
no one can say that you ripped them off.
Just remember that they're hard sectored disks with 10 sectors. I just
found a box of them in a surplus store a couple of days ago.
Yeah, but will anyone really notice? Ok, I'll punch a few extra holes
here and there.

Are you kidding, these are RARE! and VALUABLE! _prototype_ hard sector
floppies.
Why if I had one of those I wouldn't sell it for $10,000!

Does anybody have a manual for a Facit 4070 or an HP 9884A? This is a
paper tape punch/reader and has a DB25 on it.

I have the service manual and parts catalogue for the
Facit 4070 (all
versions of the logic board AFAIK).
But it's not a punch/reader, it's only a punch. It does about 75cps
maximum, BTW.
You're right -- I assumed it was a punch/reader because it had two reels.
The pinout of the DB25 depends on what (if any)
optional I/O board you
have installed in the lower slot inside. The default was a 'jumper board'
(just connections) which gives you a parallel interface. There was also
an RS232/current loop serial interface (I have that one, but with no
docs), and I think there was a GPIB card as well (which I have never seen).
If you have the jumper board or the RS232 board I can provide pinouts.
The Facit has board part number 1503 87 20-20, and the HP OEM version has
1149 36 30-10.

But as you don't mention a second card, I'm going to assume you haven't
noticed the jumper card hidden inside the punch.
Hmm, I was too lazy to take the base plate off (the punches already have a
ton of stuff piled on top), but I was able to see the small cards with a
flashlight. The one in the Facit looks like it has three socketed chips
in it with several kludge wires. The one in the HP looks like it has a
bunch of transistors on it, but no IC's.
When I'm ready to test these pups out, I'll take a closer look at the
boards.
OK, here's the pinout
Thanks! Another pearl for future researchers to find in the archive.

I don't have a manual but I think I *may* have an interface for it
somewhere. I have a 9825 interface for some sort of paper tape device but
I don't remember it having a DB-25 connector.

Exactly. It was an option on the regular GPIO interface. HP had lots of
options for this interface so it could be used to connect different things.

The 9825 interface for the 4070 was the standard 16 bit interface module
with the right links on the connector board and the right cable. 4070 interface is similar to the centronics interface,
BTW, but some
of the signals are inverted, etc.
BTW, I have the operating/service manual for that interface module, and
it misses out details of how the cables are wired and what links are
fitted for the various devices. Does anyone have that information?
No, I wish I did. I've been looking for them but haven't found it for
any of the options yet.
