Hi
I don't see anything that I'd call a power supply. The
transistors look like they might be flops/latches or buffers to
drive the nixies. If you don't find some schematics, you
could hand draw some. I doubt that it would be too hard to
follow.

This morning, a BT man was around to fix my fried ADSL router (BT model
5861 - apparently they have a known weakness in the PSU department).
The question is, was he impressed by my bank of 5 servers, all humming
contentedly away under a table?
Nope.
How about the impressive dual-processor workstation, laptop docking port,
or 8-way KVM which allows me to control it all?
Nope.
Maybe the monstrous Laserjet 5siMX, or the sleek laser fax machine?
Nope.
What really took his breath away, and had him talking in hushed tones, is
the ICL OPD I now use as my primary telephone! This (almost) 20 year old
bit of kit, which has THE best dialling system I've ever happened across
(1, 2 or 3-digit alphanumeric short-codes), and a very dodgy speech
synthesizer, reduced BT Man to remeniscences of the like I've not heard
since I was in the pub last...
He suggested that BT do offer an exchange device (as in a telephone
exchange, not a swap...) which allows similar short-code type dialling.
However, it costs "a hell of a lot of money"...
On a completely different amusement level, I happened to watch the film
Swordfish tonight (and what an outrageous film it was too...); which made
mention of "the only PDP-10 connected to the internet" (paraphrased).
Unfortunately, the PDP itself didn't make the silver screen, but a
reel-to-reel tape drive did. So, any ClassicCmp'ers seen said film, and is
it a genuine Digital reel-to-reel tape drive they use? Answers on the back
of an electron...

Thanks to the kindness of Mr. Robert Baer, I've just received a fantastic
set of 8008-related documents. As I'm able I'll be scanning them and
putting them on my 8008 web page http://www.jkearney.com/8008/. The catch
includes:
- Hal Singer's _Mark-8 (later Micro-8) Newsletter_, vol 1 #1 - vol 2 #6
(1974-1976). All kinds of modifications, programming and war stories about
the Mark-8, and later covering the 8080-based computers such as the MITS
Altair.
- Hal Chamberlin's _The Computer Hobbyist_, #1 - #10 (1974-1976). An 8008
vector CRT display interface design, cassette interface, and an S-100 floppy
controller were big topics in these.
- The Microsystems International 8008 data book (they were Intel's Canadian
second source, in addition to Siemens in Germany), containing not only the
data sheet but a complete design and monitor listing for the MOD8 computer.
- A number of MOD8 add-on designs from various individuals, including
parallel I/O, audio cassette interface, and interfaces to the Suding
scientific calculator board from Mini Micro Mart (remember them? There are
a couple of their catalogs here too)
- (this is not 8008-related, but too good not to mention) An original copy
of Tom Pittman's Tiny BASIC Experimenter's Kit with the 6800 addendum
(printed on typewriter paper on a teletype, no less). Unfortunately the IL
code interpreter source is no longer with the package. Dr. Pittman has put
this on the web, by the way: http://www.sbuniv.edu/~tpittman/IttyBitty/; the
copies I have here appear to be identical.

Hi,
For few years everything i picked up with DSSI interface
used mini-idc frmale connectors, leaving me with the impression
that that was the connector for all DSSI. Later I found some that
used mini"centronics" female connectors, so I was wrong, there
are (at least) two types of connectors.
Question is, are they compatible, and, where does one find an
adaptor between the two (or a part number for one)?

Hi Fred
I tried 22DISK for my M20 but it didn't work. The tables
were wrong, as well as that my computer didn't deal
with single density. Since it had no way of ignoring
track 0, easily, I gave up on it.
I found that the single density,
on track zero, was solved by using the M20 to pre-format
the disk and then used my routines to write the double
density stuff to the remaining tracks. If Geoff has the
same issue, he might be able to deal with the single
density the same way. I found that the first track
being single density was just a boot compatability issue.
The first track would just have enough code to switch
to double density and then the main loader was on
track 1. This meant that the code was basically the
same on all of the track zero's.
I'd forgotten that the BIOS wouldn't deal with the
single density. I was thinking more in terms of number
and size of sectors.

That's sort of what I was thinking of. Of course, as you say, it is ZX81
specific.
Were these home computer tape format's standardised in any way, or at least
based on an older standard? I seem to remember a format called
"Cottis-Blandford" from years ago. Am I right in saying that most home
computer's tape data format was 1200Hz and 2400Hz for logic 0 and 1 (maybe
the other way round). How many stop/start & parity bits (and possibly more
control bits) are sent may be computer-specific I guess.
Sampling the audio stream and decoding the 0s and 1s would not be too hard a
task if a sound card with easy access to the sampling hardware was
available. It would then be relatively simple to write an application would
allow the number of start, stop, data (probably 8!) and parity bits to be
selected, world decode the string of 0s and 1s into a byte-file. The format
of this file, again, would be computer-specific of course.
If I get time I may have a go at this.

Hi
I recently acquired a Three Rivers Computer PERQ 1, together
with PNX - a unix style OS. Unfortunately in the previous move
the PERQ HD was not locked - so the HD needs reformatting.
Does anyone have the formatter software (on 8" disk) for this
machine - I understand it wasnt distributed with the OS.
I have a PNX boot disk - but no POS so would need a bootable
POS disk with the formatter on to get the system up and
running.
Any help appreciated.
Thanks
Ian.

I don't remember exactly what's on the disks, but essentialy the two
dsks differ only in the VDU setup, and I suspect they're not a complete
p-System with all the extras. Probably the editor and compiler, etc
but not much more. It's probably possible to copy the
non-system-specific parts from another system, though.

Fellow listmembers,
I'm making a run to Portland and vicinity later this week (Thursday, so I can at least see if the rumors about Tektronix's company store are true). I'm going to be looking for electronic surplus places to add to the listings on my web site, and I would appreciate input as to any I may have missed from this list:
Da Lode Surplus Electronics, 8221 N. Denver
R5-D3 Electronic Surplus, 9770 SE Stanley Ave.
Wacky Willy's (both stores, NW Vaughn and Hillsboro).
Tektronix Company Surplus (I already have directions).
I'll also be doing some shopping of my own, but please bear in mind that my interests have swung hard away from computer hardware and back into the RF and test equipment realm. That's not to say I wouldn't like to find, say, Data I/O programming stuff, it's just not my primary focus when I'm shopping any more.
So... Have I missed anyone? I came across a phone book entry for 'Norvac Electronics' that sounded vaguely familiar, but I figure Portland area folk will know best.
Thanks much.

The localtalk bridge isn't needed if you are going to a mac that supports
Localtalk directly Basically, anything after the 128 and before the iMac.
The 128 doesn't have built in localtalk support IIRC, and the iMac and
later don't have serial ports to the bridge is needed to connect to their
Ethernet ports for Ethertalk.
If you don't have a workstation card for the II, it will probably be
cheaper/easier to get a Rom 3 IIgs and use the built in localtalk on that.

Sounds like some kind of interface to connect a computer, a monitor,
and a LaserVision player (or some similar device). Such systems were
used for training systems using video clips and stills. I remember
Jaguar using such a system in the mid-eighties; they shipped one to
each Jaguar dealer in the UK, with training disks for the vehicle
technicians -- but those were PC-based, with Pioneer LaserVision
players and fancy Sony monitors. CAV probably means Constant Angular
Velocity; which is what is used on LaserVision disks designed for
random access, especially picking out individual frames. The
Magnecraft devices are DIL reed relays, possibly for video switching.
If it doesn't have much else on it, I'd guess it doen't do any
genlocking.
Sorry, no idea what computer it fits.

Not a good choice. It used to be a constituent of thinners for
cellulose paints, but now it's not allowed to be sold in normal
hardware stores over here, for a variety of reasons (and most cellulose
paints have been replaced by safer alternatives).

Anyway, it's more drastic than you need. Turpentine substitute is
slower, but works on much the same things, and won't harm plastics.

Hi Geoff
If it is done a track at a time, you can deal with it
by using the low level disk access functions of the BIOS.
You do have to have a disk controller that supports
single density ( not all do ). There are a few articles
around that describe setting up the DMA ( needed for floppies )
and the disk controller, as another option. I've found
this method to sometimes be machine dependent so if
you can get by with the standard BIOS calls, that is
a better way.
If you can read Forth, I can send you some code I wrote
to write tracks for my Olivetti M20 ( Z8000 machine ).
I don't have a controller that does track 0 that is
single density but you can get the idea of how to handle
the controller and DMA. The other tracks are double
density ( 360K drives ). You also need a compatible
drive. You can't use a 1.2M drive to write single density
at all and double density is not properly done so
it will most likely fail to read reliably( a track width
issue ).
It may also be that your machine is supported by things
like 22DISK. Have you tried this?

Hi
When they change to newer models, they drop all
support for the older ones. Even DataI/O supports
some of the older ones for a while. But then, you
pay for that support( a bit steep for hobiest but

Hey,
I'm trying to diagnose and fix my VAX 6000, which seems to have rather
nasty power-supply problems. Specifically, I need to know what voltages
come out of the H405-E. I know about the 208VAC phase-to-phase from the
circular plug on the back. I need to know what the other jacks output,
specifically the mate-n-lock ones. I'd appreciate it if anyone could
probe around a 6000 with a multimeter and get back to me.
