How many cards are in the deck?

If it's not a lot, you can carefully number the cards in pencil, then run
them through a document scanner... though the OCR process might be a
challenge.

I have an M200 and I just had to look up in the docs (on bitsavers)
that my unit requires a Hubbel
7484 for the power cable.  Yours is different but it's likely to be
some sort of Hubbel product.

If you can, that would be great.
The unit is Model: TM 200, SN: 7704196. It was made in April 1977.

Bitsavers only seems to have M200 docs.
I'm in Australia, happy to pay for the manual and postage.
Also I can scan it and upload to bitsavers.

Re: SMD disk needed

The controller is an Interphase 2181 and it should take any disk that works 
with that. LMI supported Eagles and smaller CDC drives at first, but later you 
could define drives of arbitrary geometry in setup and later directly in the 
ROM. I know that Super Eagles work at least at the software level because I’ve 
simulated one.

Yup.

And the writeup in the maint manual gives that impression too, which didn't
help! (Hence my assumtion that it was acting in the way a plain linear
regulator might, in terms energy efficiency.)

> Diode D5 provides the current path for L1 to supply energy to the load

Right. What is the role of the pair of big caps, C8/C9. Is that just to
filter ripple, or do they play a role in the provision of current when the
supply is switched off (by Q2)?

(My guess would be only the former, since unlike the energy stored in L1,
which can be used provide electrons when Q2 is off, capacitors only store
electrons, so they can't play much of a role in the conversion of V1I1 to
V2I2, which requires 'creation' of more electrons when I2>I1. Oh, reading the
maint manual, when Q2 is on, they store some of the current coming through
L1. So I guess they have a peripheral role in the overall operation.)


> The subtle thing about designs like this is where does the switching
> oscillation come from?, as there is no obvious oscillator present.

The maint manual does cover that. It more or less says that as the output
voltage rises through 5.05V, the voltage regulator turns off Q2, and as
it falls through 4.95, it turns it back on. (Presumably when the whole
works is first turned on, the output voltage is less than 4.95V, so Q2
stays on until it gets to the turn-off voltage.)

Q7 is part of the over-current sensing, it says.

Ah, I was wondering about why they did it that way.

That's because of the higher efficiency of this circuit, as opposed to a
straight linear regulator, which would need more mains power in to produce an
equivalent power out?

I was confused by the maint manual, which says "D2 is used with Q5 and R2
to provide +15V to E1".

Got it.

Right.


OK, I think I've got a decent grip on all this now - although I still

which is different from the M200. I'll have to dig around to
try to find it again.

Manual for Documation TM200 punched card reader

[Guy Dunphy via cctalk]

By coincidence, today I started evaluation of a punched/optical card reader.
Model TM200, made by Documation Inc.

Naturally I have zero information on it so far. 
Does anyone know where I'd find a service manual or schematics?

Pics here: http://everist.org/pics/TM200/
It will get a writeup at http://everist.org/NobLog/ if it seems to be a 
feasible restoration.

The immediately obvious problems:
* Mains input connector is one of those old round locking type. Not sure if I 
have any of these.
* Hose from vacuum pump to pickup heel is hardened. Needs replacement.
* Plastic elbow fitting for vacuum to pickup heel is broken in half. Make new 
one.
* Plastic mount for status display lights is cracking around brass nut inserts.
* Four rubber transport rollers have de-vulcanised, melted, and flowed gunk. 
Urrgh, what a mess.
* Ouch, that interface connector.

I wonder where I'm going to find some card stacks for testing it? If I get that 
far.

Re: Fall cleaning - 9-track drives available

[Guy Dunphy via cctalk]

Too far? Road trip? I'm crying here (Sydney Australia.)
I have a couple of HP 7970B's (and the sevice manual) though not yet running.
But I have no 1600 bpi drives. Oh well...

I could use a small rack but I think Santa Cruz, CA is a bit too far for 
a road

trip from NEPA.  :-)   (I really regret giving all my racks but one away!!)
