Can I safely put the daughtercard into a stock Wyse 60 and get the same
functionality? What is the max distance for RS232? Are there any other
real differences? The Wyse was stationed only about 50 feet (cable wise,
crow flies about 8 feet thru a wall) from the KSU. Is that close enough
that a stock RS232 based Wyse can reach?
My Qume system is a different story, that is about 300 feet cable wise
>from the KSU.
(Although, it might be possible that the one in the Qume is fried, that
terminal "works" it just doesn't pick up anything over the serial port...
it stopped working when the phone pole in front of my building was struck
by lighting, and due to poor grounding on the part of the phone company,
half my phone system was fried, including the terminal... BUT... that
gives me the idea of pulling the daughtercard from a 2nd one of the
Qume's I have that has a bad powersupply... or was that a screen... humm,
if it is a screen, maybe I can just mix and match and get one working)
I would think the Executone terminal you have is fairly similar to the
Isoetec I have. Executone bought Isoetec many moons ago, because Isoetec
had better designs and systems. Most of the executone systems released
after the buyout have been based off Isoetec designs/ideas.

Ah, you forgot the other transport, IP over morse code(cw).
I believe RICM may have a copy of the document.

Interesting...I've had a few over the years, and have found them to
be nearly indestructible. Guess I got lucky! :-)

The cable is designated RG-62, but it's 93 ohm cable.
Cards could be connected to an active hub or a
passive hub. Passive hubs required 93-ohm terminators
on the unused ports. But with an active hub you're all set.
I have a couple of cables with BNC connectors, and I think
a few left-over crimp-on connectors that you're welcome to
have for the cost of shipping (or pick up in Berkeley, CA).
Write to me offline. I got rid of a heap of arcnet stuff
last year, alas. I think it's all at the Alameda County
Computer Resource Center :)
By the way -- how about DVD's via pneumatic tube?
Now THAT is a high-bandwidth medium. I can sell you
some pneumatic tube equipment too :)

Hmm...CAMAC comes to mind? Memory fading...

I recently picked up a box called a "ADA 1600 Pet Printer Interface".
It's a box slightly larger than a pack of cigarettes with two cables
attached to it. One cable has a Centronics type connector on it and the
other has a small circuit board with both a male and female 24 position
card edge connectors on it. Is anyone familar with it or does anyone know
which model PET it's for?

Hi,
I am looking for any information or resources relating to the UK based
Research Machines 380Z and 480Z products. These were Z80 based micros,
mainly used in UK schools during the mid-eighties.
I have a 480Z in my collection, but it isn't 100% operational and I really
need service information to enable me to track the faulty component.....Can
anybody help with any information about these machines, so far all I have
are a few collector/museum web sites..
Now I've asked my question, a little about myself. I am based in the UK and
am interested in collecting 8 and 16 bit microcomputers from the late 1970s
through to late 1980s. I have managed a reasonable collection of hardware
and software and am in the process of cleaning/restoring the hardware and
then preserving the software.
Regards
Simon Hardy

A truly bogus design. Any idea why they did it that way?

Has anyone here obtained one of these kits currently listed on ebay
for $120.
Are the parts readily available or will they have to be purchased with
the kit?
Are there any other kits being made?
