According to Ned Simmons :
In article rs.com,
says...


I lived in a rooming house not too long a walk from the main
plant there. One evening, I decided that I wanted a Coke, and as there
were no private refrigerators in the rooms, I walked about a block and
a quarter to a filling station with an outdoors soda vending machine.

The Jenney station on the corner of Albion Street and North Avenue?

That sounds about right. I did not drive at the time, so I did
not pay attention to what flavor of gas they sold. But certainly Albion
street sounds familiar. That was the one which was parallel to the
B&M commuter railroad tracks? The rooming house was owned by a couple, the man of
which was also a jeweler (watch sales and repair). Nice people. I
think that the name was Tasker, but that has been over forty years now,
so I could well be mis-remembering.

My
father always bought gas there when I was a kid. When I was born, my
parents were living on Walnut St., just a few blocks from Transitron,
but before there was a Transitron.

O.K.

My uncle, a chemist, worked there for a while, probably around 1960-62.

Hmm ... that might have overlapped when I was there.

Is there still a Transitron?

No -- a bit of Googling suggests that it folded in 1986. Sigh!
Somewhere, I still have a Transitron manual of data sheets for their
products as of about 1961. Bright orange jacket for the 3-ring binder.

Enjoy,
DoN.

It has scales marked in KW, HP and Amps. It also has one scale with a

I've visited it, but I had not gotten around to joining before
flunking out. My time there was just before the period covered by the
book, so I just missed it. If I had not flunked out, I probably would
have been in the middle of it.

And Jeff graduated before I got there, so he probably missed all
of it -- except for earlier parts of the TMRC.

Also -- I was able to correct two items in time for inclusion in
the first edition of _The New Hacker's Dictionary_.

After flunking it, it was some years before I got within reach
of a computer which I could use -- starting with the HP 9200B (sort of
an HP pocket calculator before they managed to shrink it enough to fit
in the pocket, but it was programmable. This one was at work. Later, I
got to play with the CDC 6600 and successors -- both in batch mode and
interactive via a dial-up terminal.

My first computer at home was a MITS Altair 680b, which I still
have. (Not the 8080-based 8800, but the 6800 based 680b.)

Not specifically, but it sounds like one of those slide-rule type
calculators that were produced as give-aways by various companies. They've
been designed for all sorts of specific tasks. In your case it sounds like
it was made for some sort of electrical calculations, and I've seen the same
sort of thing for machining operations (speeds & feeds for various materials
& diameters), hydraulic flow, and all manner of other engineering
applications. Every once in a while I pick up a batch of them on Ebay. My
favorite is a Pratt & Whitney Gas Turbine "Computer", which is of the
circular style but my most used is one by Holo-Krome that shows dimensional
data for various fasteners. That one comes in quite handy when designing
various projects.

Does yours have a company name on it?

I must read up a little more and have a play with it.

Hmm ... it has been a *long* time, and I don't have a map of the
area handy. The walk from the rooming house to the filling station
passed a hardware store and a drugstore. All were on one side of the
street, with nothing on the other side but railroad tracks and station.

I remember that I had to explain to any drugstore in the Boston
area what I expected when I asked for a "chocolate sundae". Anywhere
from Arizona through South Texas (where I grew up), and up through
Northern Virginia, it always meant the same thing -- vanilla ice cream,
chocolate syrup, whipped cream, and a maraschino cherry on top. Up in
the Boston area, every place had their own idea, with the most extreme
being: Chocolate ice cream, hot chocolate fudge, melted marshmallows,
and cracked nuts sprinkled on top just before everything set up into
concrete. :-)


The rooming house was owned by a couple, the man of
which was also a jeweler (watch sales and repair). Nice people. I
think that the name was Tasker, but that has been over forty years now,
so I could well be mis-remembering.

O.K. I don't think that I ever met him -- though there were
some who I never knew names for -- especially the ones who dropped into
the test equipment repair place to borrow something or other.

[ ... ]

I have some old semis in Transitron packages around someplace that I've
held on to for nostalgia's sake.

Any "binistors"? (Numbers like 3N35, IIRC.) It was a bistable
device which they discovered by an accidental mis-bond. Four leads, and
it could be turned on by pulsing one lead, and off by pulsing another.
They had memory functions in mind when they discovered it, though I have
no idea whether they actually sold any.

Another thing I had more direct experience with was the
"ref-amp". A temperature compensated zener and a transistor in an epoxy
package, used as the heart of a voltage regulator. The temperature
compensation was done by using "stabistors" in series. Forward biased
diodes with a temperature curve the inverse of the zener's. The parts
were selected by measuring voltage at a given current at -50C, +50C and
+150C (in silicone oil baths), and then computer matching them.

We got a small batch back from a customer with the complaint
that they were out of spec at some points in the range, though not at
the three test temperatures. So -- I was given the task of running each
one, individually, from -60C to +160C, and taking readings every 10
degrees. Well, at -60, the high-temperature silicone oil turned into a
grease, so there was no convection, and at +160C, the low-temperature
oil started to boil, so the solution was to mix some of each to cover
the range. This was fine for a while, listening to the ticking and
"braap"ing of the Non Linear Systems digital voltmeters (edge
illuminated digits engraved in thin Lucite, and stepper switches doing
all the selecting of a Kelvin-Varley voltage divider). But, one of the
others dumped in the dry ice to start the cool-down for the next run a
little too soon, and the bubbling of the CO2 in the oil gave it more
surface area to evaporate, causing a white cloud of silicone oil vapor
to curl over the lip of the beaker, down the sides, and into the
still-hot coils of the hotplate. That was when I discovered that
silicone oil can burn. :-) The CO2 fire extinguisher put it out quickly
enough, but there was a very fine sand all over everything from the
burning of the silicone oil.

That room also had a small South Bend lathe in it -- the first
time I ever got my hands on such a machine tool, to get a little
metalworking into this. :-) I think that it was a 9", but it may have
even been smaller. And yes, I did make something on it -- unofficially.
An anvil for staking forked solder terminals into circuit boards.

Enjoy,
DoN.

Well, "MY" first computer was "Whirlwind" which was being built by MIT
for the gummint while I was a student there.

I had a part time job working there nites as "Jeff the human
time-temperature profile controller" for the bake-out ovens they used
when making those infamous large "Charactron" CRTs which gave that
computer it's real time output display. I had to keep checking the
temperatures in those ovens and adjusting the thermostats to make their
temperatures followed whatever profile the gurus wanted.

The computer itself contained a huge number of vacuum tube flip flops
plus magnetic core memory, and used those Charactron CRTs for output
display, sometimes with motorized 35mm cameras snapping photos for
"printouts". Took up a huge amount of space and kilowatts, and prolly
had 1/100th the computing power of your Altair.

I don't suppose you have any interest in an HP freq counter that I'm

ICs in it - hundreds of discrete transistors. It's not great
cosmetically, but since it does work I can't bear to toss it and would
rather give it away to a good home.

Was this at MIT, by any chance?

Guilty as charged, Don. But I'm suprised you didn't figger that out from
my sig line. G

I did -- but I had to ask, anyway, just to get the conversation
started. :-)


MIT? Wow, you guys are, like, mega-geeks. By comparison, I'm only
a wanna-be geek.

Were you guys members of the (in)famous Model Railroad Club? Did
Levy's _Hackers_ bring back any memories?




I visited the Model Railroad Club a couple of times, but spent more time
at the ham radio station:

Since you mentioned geeks, I'm reminded that one of my buddies there,
Phil Spertus, had a daughter who followed in his footsteps and got her
Batchelors, Master's and PhD in computer science from MIT. She was
elected "Sexiest Geek of The Year" in 2001.

According to Ned Simmons :

I don't suppose you have any interest in an HP freq counter that I'm
guessing dates back almost that far? As far as I can tell there are no
ICs in it - hundreds of discrete transistors. It's not great
cosmetically, but since it does work I can't bear to toss it and would
rather give it away to a good home.

Hmm ... I'd better reject it. It looks as though we're going to
be moving, and I'm going to have enough trouble moving the machine shop,
especially with the collection of computers to go along with it.


Just let me know when you're all resettled and I'll send it off then,
along with that big Sola rack mount power supply I've been stubbing my
toe on. Freight collect. g
