I have a vague recollection of someone telling me there was a trick to
demagnetizing high density disks. Perhaps wave a magnet in various ways, even
moving the magnet to and from the disk's surface. Then again maybe it's just a

Hey everyone,
My better half recently turned this on and also a podcast with the
creator/director. They mentioned they visited "someone" with a working
VAX 11/780 to get b-roll footage for the movie. Which one of us was
it? :D

I do know the VAX-11/780 very well (although I do only own a /750), but
what is the PROMIS software good for? Does it run on ancient VMS versions
(i.e. V4 or earlier)?

Personally I like Brad's idea of a machine sound versus an intro tune. And
if we can reduce background noise (e.g. putting the machine in an anechoic
chamber or surrounding it with acoustic panels) when capturing that sound
it would feel really professional. Might be easier said than done

Awesome! I figured I'd know someone involved. Did you actually get a
vintage version of PROMIS running? They talk about it being so
"revolutionary" in the documentary, but it just seems like any other
database?

It dates back to the early 1980s and seems to run on VMS. It was
specialised software for law enforcement used to manage casework, but
could also do some pattern matching. Almost like a "prehistoric
Palantir" based upon what the documentary said. There was a large
scandal involving the software, in
There was some movie magic, so no running version of promis. I did the

up the set at my place. Suppo

I wonder if one of the old CRT demagnetizer‘s would work.

Radio Shack used to sell a "Bulk Tape Eraser". I gave mine to the
college.
Those are on eBay, and even Amazon.
About 25 years ago, Radio Shack/Tandy changed the label and box, and
called it "Bulk Disk Eraser".
The college bought one, and discarded mine.
But, as everyone knows, the one SURE

Ignorant question:
Q: When looking for current availability of bulk tape/disk demagnetizers,
on eBay, I ran into a lot of CD/DVD demagnetizers
What kind of a problem do they have with magnetism?
Or is this like the DVD REWINDERS?
Radio Shack sold two models: the original, suitable for cassettes and audio
tapes, and a later, larger and more powerful version for video tapes as
well (44-233A). I keep one of those plugged in beside my desk and still use
it fairly often, but I'm planning to build one of Chuck's one of these days

Same place as last year in the big parking lot across from Brookdale and
down the street from InfoAge Science and History Museums.
We have the Southern Monmouth County Firehouse museum selling food and
drinks in the middle.
This is a fundraiser for both museums (VCF and Firehouse museum) which ar
