[AT] Names that have become generic

Wow, Dean.  You were a couple steps ahead of the bunch by using
computers for design in the early 60's.  I hired an aero engineer away
from Douglas who worked on the DC-10.  At that time (the 60's) they were
still using multiple nomographs to determine flight characteristics for
the air frame.  Maybe that's why they had trouble with the engines
falling off.

Steve:

Yes, I went through the era of designing digital logic circuits and
analog
amplifiers with discreet components. In the early 60's, believe it or
not, a
single flip flop made from discreet components sold for $40.00 ea and
took
up half of a 4" x 5" card. The first digital computer I worked on in the
early 60's had 4K of re-circulating delay line main memory. It also
happened
to be THE FIRST desk top computer but it was about a 4 foot cube! Data
entry
was accomplished with a "Greeny" or a teletype machine using punched
paper
tape. No disk memory at all. We announced a new computer, a model 440
and it
got its name from the fact it had 440 circuit cards in it. That was a
big
scientific computer. Very fast for its time. 

But the analog computer stuff was really the thing in the early 60's.
Digital computers were very slow doing certain computations. Such as
summing
up multiple variables and/or integrating variable information. These
could
be done so much faster with an analog summing/integrating amplifier. The
computer I worked on had 120 of these summing amplifiers or integrators
available for simultaneous use on any given patched up problem. I was
part
of the design team that developed these analog computing amplifiers. 120
variables per computer, then 4 of these analog computers were connected
together and then in turn connected to the most powerful digital
computers
of the day creating an awesome Hybrid computing capability. A Multi
million
dollar system in those days. These systems were used in the aerospace
industry for flight simulation in the days of the early space program
and
the design of the jumbo jets such as the 747's and C5's. These were
heady
days. Typical installations were in excess of $7 Million and that was
when
$7 Million was a lot of money.  

I was a young bench circuit design engineer but gradually advanced into
being an overall system design engineer as well. I was also offered the
opportunity to help the installation teams achieve customer acceptance
which
was a major undertaking as many acceptance tests and performance
milestones
had to be met. This caused me to get experience dealing with the upper
management of many of the major firms around the country. This
experience
was an eye opener for me and caused me to want to get away from the
design
side and move into the marketing/sales/management side of the business.
That
began my career in marketing/sales/management in several high tech
companies
on the West Coast, eventually ending up General Manager of a fairly
large
rapidly growing company here in NW Washington state. Then I became
retarded
and got into this interesting hobby of antique tractors and have
reverted
back to my childhood. A complete circle. I have forgotten more about
circuit
design and high technology than I ever learned. The issues those of us
in
management have to deal with just do not allow one to be nearly as
technically competent as sometimes we would like to be. I had an
interesting
career, however. Enjoyed the experience but don't miss the stress one
iota.

You mean as in  AND/NAND OR/NOR and other gates used in TTL and later
CMOS circuits. I recently received a bunch of cards out of an OLD
machine (two chips and approx 100 discrete transistors per board). Makes
me respect the folks who managed to design and fly Apollo equipment with
less computer equipment than a modern calculator.

I still have my Curta sitting here to remind me what state of the art
meant then.... And how truly bad some items are designed and made now..
