Well, I called over to Zendex today to inquire about the system I found
and talked to a sales engineer. He's going to try to dig up some sales
brochures and stuff for me.
On an interesting note, he began drilling me on my knowledge of Multi-bus
(of which I have none) and then explained to me that they still have a
market for the old systems and boards and they are in need of someone
technically competent with Multi-bus to hire on a consulting basis.
What they need is someone who knows Multi-bus, CIM-bus and ISBX modules
for testing and assembly. They need someone who knows enough to assemble
the boards from schematics they still have lying around and to test the
boards' functionality. They currently don't have anyone on staff who has
expertise in this older technology, so they would like to find someone
young, old or in between to hire on as a consultant to do this work (he
recalled a radio program on NPR that we both heard recently about older
technology workers having difficulty finding work as they are being
superceded by younger, more "energetic" workers who work for less pay). I
told him I'd put the word out for him as a favor (and also so that he'll
feel obligated to give me stuff).
The Company is Zendex Corporation in Dublin, California. Their phone
number is (925) 828-3000 and you want to ask for Howard Czapla. I'd
appreciate if you could also pass along to me the name of any prospects
you refer.

I recently found a PS/2 MOdel 70. Does anyone have an Ethernet card
for it, that has a coaxial cable connector and that could be sold to me
for
not-too-much?

I am talking about either. In truth, I am interested in AI, whose goal
is to approach the functionings of the brain. So, whatever features
each shares, or differes in is fine. But I suppose that "idealized"
networks are what I mean, that is ones in a purely mathematical space.
For one thing, how are the connections made if not randomly? I
thought it was essentially based on the closest free neuron.
What kind of summation is it if not linear? Do you mean that if the
threshold is 5, 4 is more than to times closer than 2? What does that
mean, if anything?

<I may be wrong, but I thought the RL01/RL02 needed a seek to even switch
<heads to guarantee the #0 and #1 head were on cyl when reading/writing.
Head 0/1 are on opposite sides of the platter so they will always be on
the same cylinder. So there are 512 cylinders of two heads, 40 sectors
of 256 bytes per track (one head/side of a cylinder).
There are a lot of ways to organize that physical layout.

128K (As I've heard that it could go to...)
Thanks, >>
pocket rocket is applied engineering's equivalent to apple's language card.
it's very small, and doesnt require a cable to the motherboard like earlier
models did.

I'll vote for this. My logic is:
a) it's an interesting specimen as is, displaying the ingenuity and
constant striving for performance that the computer industry has had since
day 1.
b) you can always remove the extras later.
a) has it's merits, but wouldn't be my main motivation. b) on the other
hand, would be reason enough. If nothing is being harmed, don't do
anything now that you could do later.

I found a really neat computer the other day. Its made by a company
called Zendex circa 1980. It's an 8085 multi-bus machine. Inside it has
the processor board, a disk controller, an I/O board, and a parallel
interface daughter-board bolted to the back, but which is connected to the
system bus by way of a ribbon cable. The front panel consists of 8
interrupt and one reset switch.
A very unique system, in that I've never seen one or even heard of the
company before, but nothing special. However, the neat thing about this
computer is that the company that makes it is still around and in fact is
right around the corner from where I work! When I first examined the
computer, it had a label with the company's address: 6680 Sierra Ct in
Dublin, California. I went there a couple days ago and they are in almost
the exact same spot (one address over now). The slogan embossed on their
front window reads "International Manufacturer of Microcomputers Since
1979". I went inside, explained who I was and why I was there, and asked
if there was anyone I could speak to about the system to get information
(and hopefully documentation) on it. I was told to call back as everyone
was in a meeting so I'll be bringing the system by today to bug them.
I finally had a chance to open it up last night. One of the neater things
is that the front panel circuit board has imprinted on it "Made in
Dublin". Now, the reason this is quaint is because, although Dublin is
part of the "Bay Area", its not by any means considered a part of the
"Silicon Valley". So "Made in Dublin" I think is a cute little
acknowledgement of the fact that the company was removed from the main
hi-tech bustle of that era. This particular area where I'm at is not
foreign to significant computer companies as Processor Technology (makers
of the Sol-20) made their headquarters just a mile away in Pleasanton,
California. It's nice discovering that makers of classic computers used
to be right in your backyard. It's even nicer when they're still around
so you can go bug them for information.

Oops! Apologies to those who weren't interested. Although neural nets go back
a long way, they're not classic computers, and I thought this was being sent to
Max, not the list.

I guess this is a little off-topic, but I'm not exactly sure where to ask
about this... Anyone know anything about the Intellicom Mega-Link four port
buffer? Four buttons and six LED's on the front, a row of eight 256k RAM
chips and three rows of sockets for more RAM, and the three DB-25 and a
36-pin centronics connector on the back. Any ideas on how to hook it up?
I'm gessing there was either a special cable for it(centronics to serial
port) or maybe it was designed to attach to a serial port card or
something...

whenever i find a computer that's been modified, i leave it as is. for
example, i have a mac512 with a internal hard disk called a hyperdrive. quite
a clever setup and i also have an apple ][+ with an aftermarket encoder board
which gave autorepeat, macros, type ahead, and all the characters that the //e
could do. i also have a mac IIcx with a 68040 processor board. i keep all
modifications as they themselves are worth as much as the computer itself and
provide personality to the machine.
