Does anyone happen to know anything about obscure sizes of tractor-feed
paper?
We've now got the console typewriter of the PDP-1 at the Computer History
Museum working correctly. It is an IBM Model B electric typewriter
modified by Soroban Engineering for use as an I/O device. Soroban added
an encoder and a decoder mechanism, using switches, solenoids, bails, etc.
There was a bent leaf switch contact that resulted in incorrect character
codes on input, and two stuck solenoids that resulted in incorrect
characters typed.
Anyhow, the typewriter will accept individual sheets, but it also has
tractors for continuous forms. But the distance between the sprockets
is approximately 13 1/8", which is narrower than the sprocket spacing
of standard line-printer paper.
A Google search reveals plenty of places that sell 9 1/2" wide or
14 7/8" wide continuous forms, but are other sizes readily available?
Thanks!

Hi everybody,
the information technology "museum" at Erlangen University (for which I work
part-time) will be aquiring two HP 1000 systems in the near future, an A600+
in a 16-slot cardcage with a "piano-seat" disk/tape unit (7912P) and an A700
in a big cabinet with rackmount storage (7908 and 7912). I'd really like to
have them arrive undamaged.
As noted in the archives, there should be a shipping lock on these drives
(see http://www.classiccmp.org/pipermail/cctech/2003-April/013531.html).
We've already received the documentation for the system, but obviously the
now important parts (Disc Drive Installation Manuals 07908-90902 and
07912-90902) are missing. Some Google activation brought up several sellers
of used drives along with a few classiccmp threads, but no online copy of
the manual.
Can somebody please tell me how to properly prepare the drives for
transport? From what I read here, they're not very reliable anyway, but one
doesn't need to make matters worse. They're in a building just across the
yard, but as I always need to coordinate three parties to do something
there, it would be best to know what to do *before* actually poking around
in the cabinets.
Your instructions (or redirections to web resources) will be sincerely
appreciated.

What do you folks make of this site?
http://free-game-downloads.mosw.com/
That have a bunch of software for download. Some of it is Abandonware.
Or at least it's claimed to be Abandonware. How do we know it's
Abandonware? They have nothing on their site (that I could find) that
confirms that these are abandonware, and there are thousands of titles
there.
They want money if you want to download anything. I can understand them
wanting to cover their costs, but this seems pretty sleazy to me.
Opinions?

I recently obtained a Votrax Personal Speech System which unfortunately for
me, did not include the power supply or the manual.
Thanks to Robert Stek's informative post
(http://www.classiccmp.org/pipermail/cctech/2003-February/010608.html) on
this list in Feb '03, I am in the process of constructing a power supply for
it.
(i.e. I eBayed a 28VAC transformer and am using an 18.5VDC laptop power
supply instead of 20VDC which HOPEFULLY won't hurt anything, until I find a
satisfactory 20VDC power supply, and am cannibalizing a DIN-5 connector from
a dead keyboard)
However, I still lack a copy of the PSS's manual, so I can't figure out how
to set the various device modes, to control the AY-3-8910 audio generator
chip, etc.
If anyone here has the manual for the Votrax Personal Speech System and has
some means to scan or digitize it (a digital camera will work) can they post
or send me a copy of the images? It would be very much appreciated.

P.S. I'm sorry if this message gets onto the list multiple times, I
initially sent it to cctech from my comcast account with a different return
address, and I thought it had been 'moderated to death'. So I sent it to
cctalk instead, with the same account... and my message still never showed
up. (I guess classiccmp.org is rejecting all comcast mail as spam or
something nasty like that) So now, I'm sending it through hotmail, and I
HOPE it gets through...

24 pins makes sense for HP-IB/GP-IB, and the "piggy-back" connector
looks right, but the other end doesn't look like the DEC GP-IB cable
for my IBV-11, either. Is there a part number on either of those white
labels that are visible near the ends?

Hello,
I was looking for MaxxBoxxes when I came across your Musings. I was
curious if you had ever found one? And if I may ask, where have you
been looking?
Thanks,

Hi all!
I was just wondering if anyone on here knows what (if any) hacks have
ever been done to a Philips/Magnavox VideoWriter? I was mainly wondering
if anyone has ever been able to get any other operating system (namely
CP/M) working on these boxes.

I now have 7 of these liberator 220's. I don't have the cables yet to
test them, or even know if the cables I have coming will work.
Looking inside the cases they have 2 full height drives in there. They
are standard 50 pin scsi drives.
The two drives connect to what has to be a scsi-->dssi board. This is
making me think that could change these drives for something bigger.
But if anyone knows more about these I would love to know. I was
wondering if the two drives inside are mirrored or in an array. The
arey in a rack all daisy-chained together, unless someone has messed
about with it, I thought dssi was max 7 devices.
They also have a programmable front panel, with no instructions and
just three buttons. Does anyone know how this works.
Also does anyone know how the speed of these compare to standad dssi drives.
This is going to go great on the 4000/705a. It would be nice if I
could swap a couple of the drives for 18gb.
Apologies if you read them, I have asked the same questions on both
vms and dec newsgroups.
Thanks
Dan
