I don't know when it started, but it was being worked
on in early 1951. I do not know if it was an acronym
or a project name, but it was always all-capital
letters. Has anyone here ever heard of MULDAR ?

aha ! Just de-classified.... This is, I infer,
related to the Bedford Experiments (Cape Cod Experiments)
to use Whirlwind computer to track invading aircraft.
Page 2 mentions a suspension in experiments due
to engine trouble of the B-25 in which the airborne
equipment is located., mentions interuption because
an F-51 was sent for repairs. Also talks about sending
3 sets of radar data per phone line. 1 February
1952 Memorandum M-1389 Digital Computer Laboratory
M.I.T.

page 7. An outline has been written up for
a set of programs which will allow us to test parts
of the Cape Cod Muldar Program before the magnetic
drum equipment arrives from E.R.A. The proposal
is to record on magnetic tape blocks of filtered
radar data from 1, 2, or 3 radar sets. The computer
would carry out the necessary filtering and recording
operations. A second program would then be read
into the computer which would process the radar
data on the magnetic tape, a block at a time. In
this way, the processing program could be completely7
divorced from real time, allowing us a great deal
of flexibility in testing various information processing
methods.

And now that I know what terms to search on, this
de-classified document explains it all....

Very interesting, but what on earth caused you to
search for information on the Muldar system? Now
that you know, what will you do with it? Are you
writing a book?
BTW, what does Muldar stand
for? Is it a person's name, or some acronym where
the "dar" part is from "radar?"

I am doing research for a book. I am going through
notebooks of
Dudley Allen Buck who died in 1959 at age 32.
His public image was that he worked developing
computer components, including the cryotron. However
he was doing much more interesting stuff than just
computer components. Going through documents we
find that as a consultant to the N.S.A. he was working
with some pretty interesting people. One
of the names in his notebook was located and I had
a discussion with him. His first job for the NSA
was trying to fix a distribution system for the
clock in a 3 MHz computer in 1952. A time when 'fast'
computers used a clock of one or two hundred kilohertz.
I am finding other very interesting things.
I am surprised how much of this stuff is STILL
classified for national security.
