Today I found the company, Techniques, Inc. in Englewood, New Jersey, that
made the printed circuit boards for the "Radio Electronics" Mark 8 computer.
They are in the same location as in 1973. Afaik, they have no web site
or email. I called them to ask if they could look for
any material, or any information, like how many board sets were made or sold.
I found nothing. They first thought that "Mark 8 microcomputer" was the name
of another company. I finally found someone who said the company was bought
in 1987, and that all information before then was gone.
I've also learned that the printed circuit boards were 2-sided, but had no
plated-thru holes. This may have caused problems to IC solder connections,
making reliability problems. I don't know if this would make buyers abandon
them making the numbers larger or smaller than otherwise.

this isn't really "classic" per se, but...
I grabbed a performa 636cd, w/ a 500mb ide drive. being curious i
ripped out the 1-connector ide cable and connected a 2-connector; the
mac ide quantum (which specifically says "apple" on it...) was set as
master, and i popped a seagate on as a slave. no boot unless i popped in
the mac disk tools. if i take off the 2nd ide drive, it boots. being a
total mac idiot, is it even possible to use a ATA ide drive on a mac? or
is there something else to this that i'm missing? any help would be
gratefully appreciated. thanks.

Yes. Your next step on the road to enlightenment is to webulate to

Found this on usenet, don't know if any of you like that CoCO stuff.
just thought i'd pass it along. please reply to him directly.

Paper tape, of course!
There is an action on me from this list last year (I think) to
investigate the possibility of Tyvek tapes. I still intend to do it,
but I don't know when!
Philip.
This past weekend, I picked up a few cases for SCSI disks... they have
a device on the back panel which allows one to select the SCSI id by
just pushing one of two buttons until the proper ID shows... I've
used a VOM to figure out which wires from this thing are what, but the
connector it same with is not compatible with the (as far as I can tell)
standard of three sets of jumper-width pins.
I'd like to button this thing up so I don't have to open it again (except
to replace a bad disk) but can't find anything which fits the spacing of
these pins...
For those for whom this info would be useful in telling the spacing, the
disks are RZ35s (from DEC). I don't know who actually produces them.
Any help appreciated...
My next plan is to try one of the inter-board connectors (one board has a
socket and one has pins)... the socket connector seems to have proper
spacing, but I've yet to actualy try it...

Here's an excerpt of a posting that triggered my IMSAI smart agent.
Does anyone recognize his name, or the company he's describing?

Just because something is possible doesn't mean that anybody's gonna want
it.
The very first business that AICS was involved in was computer-based speech
synthesis. Indeed, that's where our name comes from (AICS = artificially
intelligent cybernetic systems). The company grew out of something that had
previously been just a hobby of mine -- and a potential dissertation project
for graduate school: completely host-based speed synthesis, de novo,
where an
electrical analog of the human vocal tract was commanded to truly synthesize
new speech rather than simply play back digitized human speech.
In 1976, when I finished school and the company was formed, we actually
made a
lot of money surprisingly easily and surprising quickly selling speech
synthesizers as drop-in boards for Altair and IMSAI microcomputers. That
was a
time you could sell anybody anything. Every conference was a feeding
frenzy of
buying. You threw something up in the air and ten people wanted it.
In 1976 also, when I became a professor at our local university, several
students also continued on with the speech synthesis work. Vickie Kurtz, a
person who you actually sort of know because she is more or less single-
handedly putting together QCTerm now, did her master's work with me then.
For
her thesis, Vickie put together the best vowel synthesizer that I ever
heard,
using voltage-controlled oscillators, controlled by a simple rom-based
finite
state automaton so as to simulate the mechanical inertias found in the vocal
tract. Although her synthesizer didn't have any sort of noise generator
in it,
so it couldn't form the fricatives (hiss-like sounds) necessary for full
speech synthesis, its vowels were the most human-like I've ever heard and
were
essentially indistinguishable from a baby's babbling or cat-like animal.
Vickie finished in 1982.
A year or two earlier, Texas Instruments got into speech synthesis in a big
way using a technique halfway between digitized speech and speech
synthesis, a
process that might now be called "smoothed sampling". It worked much better
than true synthesis in that its intelligiblity was quite good. Because of
that, TI was able to sell a variety of manufacturers on the idea of having
talking washing machines, microwave ovens, vaccuum cleaners, etc. The most
expensive of these talking machines was the Chrysler LeBaron automobile
-- and
people (the end-users, not the engineers) found all of this incredibly
irritating. The single most requested option on the LeBaron, by far and
away,
was to have the speech generator deleted.
Talking appliances were a technological fad that lasted only about three
years, 1979-1982.

Yeah, me too. But this is where I stopped: it was an 8085.
...
The Star presentation was certainly well attended -- it was packed to
overflowing! I was out in the lobby watching the presentation on a
monitor, and apparently there were other folks watching other monitors
in the cafeteria. Anyway, that is why I gave up on notes -- couldn't
concentrate on the palmtop keyboard and the monitor at the same time.
Afterward a bunch of us did get together outside the auditorium lobby,
Uncle Roger tried to make me hold up a classiccmp sign, I tried
waving my appendages a bit whenever I saw someone I recognized, and
somehow I think we completely missed Rax. Sorry about that, Rax.
I will try to plan better next time.
So who was there? Roger Sinasohn, Rachel ? (Uncle Roger's girlfriend
-- the schoolteacher who is always on the lookout for Macs), Doug
Yowza, Doug Coward, Paul Coad, Sam Ismail, Edwin El-Kareh, and y'r
humble narrator. Stuff was swapped, stories were exchanged, we moved
to the parking lot, yakked some more, then security came around,
someone made the mistake of asking me where to go and I suggested the
El Paso Cafe in Mountain View. (Hey, I know *I* can get some
good cheap eats there.)
Notes:
(a) At least some of us seem to want to do this get-together
thing again. Of course we did not reach any consensus w/r/t time
and date as Roger now wants to check and see whether his tap
dancing lessons collide.
(b) We need to start earlier, 9:00 PM is late for dinner and
the El Paso closes at 10:00. Other places close earlier than
that.
(c) So...fine, here's a time and place for all us Bay Areans to
argue over: Second Thursday, 09 July 1998, 7:00 PM, El Paso Cafe,
1407 W El Camino Real, Mountain View. Y'all can flame me about
this in public or private, and I'm still open to change, but I want
to announce the real time and place on 30 June.

Indeed, and with DVD being able to read CDs you'd expect no difficulty in
reading CDs for the next 20 years or so. I'd certainly want to be able to
listen to my music CDs for that sort of time-span. In fact, with the number
of CDs I have, if I listened to a couple a week, it'd take 20 years :-)
