Are you certain that the interface isn't wired for current loop?  A lot
of these CNC (I'm assuming that this Fanuc unit falls in that category)
used the CL interface.  Connector's the D-25.

to front panel keys.  However, nothing is emitted onto 232.  The D25 - D-9
transition has all the RTS/CTS and DSR/DTR/DCD lines knitted appropriately
and indicating 'correctly' on blinkenlites.


I don't know anything about that specific setup, nor anaything aabout your 
personal expertise.


When you say "nothing on 232", is thatr per looking at the wires of the 
cable?  Or just not getting anything displayed by Putty?


When you say "knitted appropriately", since that is NOT referring to "as 
per the manual" (or is it?), have you checked all inputs and outputs?
Sometimes devices, at either end of the cable, have unexpected 
requirements,that are not usual parts of the RS232 "standard".


For example, I was once asked by the "Radio Shack Computer Center" to help 
them connect a Votrax to a Model 2 (for a blind customer).  They had tried 
all of the obvious commodity "null modems", etc.  I used a "matrix 
switch", but also had to solder one additional jumper for a pin that is 
not "normally" used for such things, and no obvious reason for being used. 
I no longer remember which pin; it was possibly #10 or #12, but it might 
just have been #22 ("ring indicator").  To avoid the bureaucratic 
administrative nonsense needed for them to pay me, I accepted a gift of a 
Model 2 Technical Reference manual as compensation.

Hi Martin, do you have an RS232 light box like this one?

I am so confused why you are not seeing anything, I have had 3 PPRs (2

Thanks for the offer of the DosTek 440a.  However, my problem is getting the 
232 output to wiggle a CRO not to input and log the serial data.

Thank you for the manual and the suggestion of pulling all the jumpers.  With 
all but jumper 1 out, it punches and remote starts (Xon) the reader at 4800 
8N1; unchanged functionality.  However, still, nothing is emitted from the 232 
for consumption by Putty.

Unfortunately, the SystemP manual contains identical pages on the PPR to those 
in the PPR’s own manual.  Nonetheless useful as context, and for perusal in 
slow time.

Possibly going up to VCF, stuff I would like to sell/get to proper people pdp8/12/HP stuff

Hi all!

I'm thinking about going up to VCF in Wall next weekend. I haven't been 
to it since it was the Trenton Computer Fest (think late 1990's) so I'm 
not sure what the protocol is on tailgating, trading stuff or whatnot. 
Appears that they have a "sale room" you drop things off in with prices. 
Ok


Things I could "sell" if anyone's interested:
HP1000e computer, dead power supply, basic boards, no advanced memory.
HP9825B likewise does not power up, but it's there.
Microvax 2 boards, stuff like that.
Spare 11/24 CPU boards (I have a bunch, all work, no idea why I have all 
them)


Stuff I could bring to get out of my house and into the right hands:

Big box of pdp12 schematics. This came from my olden days when I had to 
turn up a pdp12 because it will not fit in a station wagon. Still it 
looks like board locations and a lot of 12 stuff. Big box, heavy to 
ship, easier to drive over.


Ton of pdp8/12 IO cables. These are the black circular wire ones, I 
think negibus. There's also some posibus ribbon cables but I'll save 
those for my 8/L's. If you need a set, let me know.


Stuff I'd trade for:
AF01 A/D converter. I don't have Negibus anymore, but I did check/reform 
the power supply and hooked it up and things do light up. Bunch of extra 
channel cards (I think it might have all 64). Would trade for a memory 
box for an 8/L.

Re: Quantum ATL-7100 DLT Changer in SLC

You wouldn’t be able to put TK-70 drives in this, wrong interface.  I don’t 
know if DEC DLT drives capable of reading TK50’s and TK70’s will work in one.  
We only used DLT III and DLT IV tapes in them.  We first got one of these 
something like 25 years ago.  The earliest ones are rock solid, really well 
built, and very simple to repair.  Same with the smaller Quantum 4/52.  At the 
time Quantum wouldn’t send out a Quantum FE to work on the 4/52’s or 7100’s.  
I’d get the guy out to diagnose the problem, get the replacement parts ordered, 
and then when the parts came in I’d never tell him, I simply replaced them 
myself.  Just be careful when taking the big side panel off that hides the 
electronics, otherwise you’ll rip out the sense switch.  If you can find a 
source of spares, you can probably keep one of these going without too much 
trouble.

As for the problem this one has, with the load port, just fold a piece of 
corrugated cardboard in half, and use it to hold the door close, I ran one in 
production for a couple years, so I could avoid putting in a service call.

I’ve worked with Tape Libraries for over 25 years, and the 4/52 and 7100 are 
two of my favorites.  The Quantum P3000 is my least favorite.  The Quantum 
i2000’s and i6000’s were also rock solid, but I wouldn’t want one of those at 
home.  

On the topic of old Quantum tape libraries, does anyone happen to know of a 
company that will provide 3rd Party support on them?

Just pick it up, and read the SETI tapes ;-)

I have a Quantum ATL-7100 100 tape DLT changer. Last I checked it worked 
fine. It's almost as big as a fridge. I have around 100 tapes for it, 
not all the same density. It uses fast/wide scsi-3 differential for the 
drives. I think I have 2 working drives in the cabinet plus one or 2 
separate external drives.


I think my drives are DLT-7000 or similar which gives a total capacity 
of 7TB.


Upgraded with SDLT 220 drives and tapes the chassis would have a 
capacity of 22TB.


Anyone interested in picking this up in South Jordan Utah? (outside Salt 
Lake City).


The only issues I know about it, is the tape loading pivoting door is 
not quite rotating correctly, and I replaced one of the AT power 
supplies with a unit that is NOT autoswitching. So if you want to run 
the unit on 220V instead of 110, you will need to change the chassis and 
the replaced internal power supply.


It's really fun to load it up with tapes, then tell it to auto-shuffle 
them. I have the door hot wired so you can open the door while it's 
operating. Easy to restore the switch if you don't want to.

I’ve torn it down this morning and put some pictures on Imgur.

Should be fairly comprehensive. It looks in good condition, with nothing 
obviously wrong with it.

If there’s anything i’ve missed, or that you’d like better pictures of, let me 
know. I suppose all that’s left to do is warm it up and see if it works. 

Cheers,
