I recently obtained a Votrax PSS which 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. However, I still need a copy of the manual, so I can
figure out how to set the various modes of the device, and control the
AY-3-8910 audio generator chip.
If anyone has the manual for the Votrax Personal Sound System and has
some means to scan or digitize it (a digital camera will work) can they
send me a copy of the images? It would be much appreciated.

My father has a very much loved Panasonic 805 calculator.
However, in recent months, one of the LED segments has begun to
misbehave. It is getting steadily worse. What happens is, in general the
segment is dim, and once a segment lights, it doesn't seem to turn back
off until you clear the calculation. As a result, very quickly, the one
segment just stays on 8.
Since this is the ones column, it effects all calculation displays (the
calculation itself works fine, it always knows what the number should be,
it is just the display of that number that doesn't work).
Does anyone have any repair info on this calculator? Schematics or
otherwise? I'd love to be able to open it and replace the segment, or
whatever may be misfiring to cause it to display wrong. He hates to give
it up, but he is finding it increasingly hard to use.

I received the following email:
I have two DEC 72 inch high racks.
They contain some custom electronics (useless to anyone else) and power
supplies. The racks are in good condition.
These racks are available for pickup only in eastern PA.
If anyone is interested contact me off-list.

Hmm, would probably have to be a FOONLY running TENEX or something of that
era, I don't think VAXen running 4BSD quite cut it. For the record I run
MicroVAX III's with 4.3BSD-Quasijarus, but I really hope that I'm not the
oldest and that there are some people running plain 4.3 or even 4.2 on an
11/7xx connected to the net. Hell, since mine are all MicroVAX III's,
even someone with a MicroVAX II will beat me. But then I will probably be
putting together a new router soon and that one will have a MicroVAX II
CPU, so at least I'll have that.

Dave,
I've got boot disks for TRSDOS 2a and P&T CP/M 2.2m if you're interested. Reply to me off list and we get something going.

Hi Guys,
Have a TRS-80 Model II which I am planning to restore (probably
get started over the holidays) - but one thing I am going to
need is a boot disk. Anyone out there got a working Model II
system? (This is the big "business" version with the single-
sided 8" drive).
Regards,
Dave
PS: Also still looking for a Cromemco System-3 boot disk.

Hi Rich,
Since no-one else has repsonded, I uncrated my 8800 and measured the switches.
This measurement is difficult, because the top of the collar does not protude
through the front panel, and in fact does not come all the way through to the
face of the panel.
I measured the switches by holding a toothpick against the top of the collar,
and straight out beside the switch - marking the top of the switch, and then
measuring the toothpick. Measurements are from the collar to the furthest out
edge of the dome at the end of the switch handle.
Both switch types (two position and three position) are exactly the same length.
I measured the two position switch by positioning it 1/2 way (straight out) .
And the measurements are (drum roll please):
11mm (7/16 inches)
Regards,
Dave

To the half dozen+ listees who responded to my listing this computer as available in November: The guy who had the Eagle has certainly moved out of his apartment by now - as it is well after the first of the month. I presume the box went to computer heaven and we were not able to rescue it. I guess that's the way things go sometimes. Thanks to all. Bill.

I'm looking for an M9312 bootstrap ROM for an RX01 drive. I believe the DEC number on the chip is 753A9. Does anyone have one of these that they would be willing to get rid of? I have other M9312 ROMs to trade.
Thanks,

I got the last box of junk from my brother, and just inventoried
the floppies, going by the labels. I likely have errors in
sidedness/density but they were all made on one of two CP/M
machines; I have one here and the other (my father's) is still
in Mass and I can get it if necessary.
I have no idea whats actually on them or which ones are readable,
that come snext after I power up the cards. I've gone through
the chassis already and it's fine. I'll probably do smoke
tests today.
There's some good stuff I think. BDS C, CBBS from 81 (sources
plus BBS files), Stackworth FORTH, JRT Pascal, some other
Pascal, Aztec C, FORTRAN IV (likely TDL/Xitan), F80, M80, L80,
etc (m'soft) basic compiler (ugh) old DBASE, etc...
I'll make everything available ASAP.

I'm looking for a DECstation 5000, a fairly recent and marginally
classic MIPS workstation DEC sold in the early 1990s. (Well,
it's classic to me for nostalgia reasons, but I won't get into
that). I'm specifically looking for a 5000/133 or /150, but
really any 5000 will do.
I'd be happy to pay shipping and a reasonable price (reasonable being
something in the < $50 range, since that seems to be the going rate),
and/or I have a MicroVAX 3100 (desktop case, 16MB RAM, 1GB disk,
8 serial lines) I'd be happy to trade.
If anyone has a lead on one, please let me know!

Hello, all:
If anyone has access to an Altair 8800 (the original model) and can
measure the toggle switch handles, I would greatly appreciate it. I need the
length of the handle from the top of the threaded collar to the end of the
handle.
Thanks a lot.

Marty Greene,
There are others of us who have TI 990/systems in storage. I have 2 990/10 systems. DX-10 OS with 10M cartridge (CDC?)drives. Mine came from a Paradyne Corp Modem Analysis system tracking 300 Paradyne 2400 Baud multi-drop circuits on an 800 hz subcarrier over dedicated lines. So I have lots of serial ports...Each modem had data and an analysis port.
Sincerely

But measuring by volume isn't necessarily the best method, either,
particularly for flours that vary in volume depending on how long
they've been sitting, the weather, or whether they've been sifted.
They teach fractions like that in third or fourth grade.
There's no excuse.

Contrary to what Tom Jennings states in a later post, there
are sound physical reasons for using fractional systems
when dealing with the physical world. I'm not defending
the English system that is a hodgepodge of poorly
related measurement standards. The only reason we have
a decimal system is because of the number of fingers we
have. Hardly a sound reason to squeeze physical relations
into. One wonders why there are 2.5mm screws when the
decimal system works so well.
If we'd had 8 finger, things would have been so much
easier to work with. 8 is 2 cubed and one hand would
be 4 or 2 squared. These both fit nicely into the physical
world were squares cubes are most often worked with.
Even logs would have made more sense under a base 8 system.

I've been trying to find some actual history on the 50/60
thing on the net but so far, all I was able to find was
that cell phones are frying our brains. My understanding
was that it was a balance between efficient generation
and efficient transformers. The voltages were mainly to
control line loss. In the US, most people live close to
their distribution transformer and line loss is not that
high at 110-115V.

On all of my replaced SCSI drives, I use SCA adaptors and SCA drives- much
easier to get nowadays than 50 pin models, and also newer. Any drive will
work-they do not need special firmware
The deal for SGI sleds is as follows-
The 50 pin cable goes into the 50 pin narrow SCSI socket on the adaptor- self
explanitory
The power cable will often need to be teased out a little longer (at least on
Indigo2, I don't have my Indigo sled at hand)
For the SCSI ID cable (the 6-pin bit) you will need a VOM/DMM. One side will
have a bank of 3 wires, the other will have 1 wire. On the adaptor, there will
be 3 pins wired together -> these are ground, connect to the single pin side.
The other wires set the SCSI ID based on which slot in the Indigo the drive
is installed
If you choose to hardwire the drive (not as neat, but a definite
possibility), remember that on IRISes the host adapter is ID 0, so the first (system) disk
is ID 1- and so on. Most computers have the host adapter as ID #7, but not
Siggys.
Best of luck to you, they are very neat machines, with a slick UI (Indigo
Magic)- For IRIX 5.3 be sure to get the free IDO (Development Option-compilers
and headers, available from www.sgi.com)

Hi Sellam
Do all the pins show low ohms to each other? It might
be a center tap or even just a ground lead that doesn't
carry current. Since you have the box open, you should be
able to see where all the wires go.

Hi Bob
There used to be a place around here called Motion Industries.
I believe they changed there name but they were a nation wide
company and had branches across the nation. They carried
all the standard cogged belts and such. I'm sure they'd have
what you need.
They might still have the same name or something similar.
It has been a few years since I used them ( like about 10 or so ).

Can anybody tell me if a "proper" (i.e. true IBM compatible) CGA (CGA, not
MDA, EGA or VGA) monitor had a male or female connector?
I know it had a DB-9 with approximately this pinout
1,2 Ground
3 Red
4 Green
5 Blue
6 Intensify
7 N/C
8 Hsync
9 Vsync
All signals are TTL and active high, as I remember.
Anybody in the SF Bay Area got a real CGA monitor that they don't want
anymore?
Thanks,
