Just as my first product was about to go to market, the company president
decided we needed copy protection. He wanted Prolok. I objected, and
proposed that if I could break it in 24 hours, we wouldn't use it. I took
25 hours, and we did use it (fair is fair).
I finally found my notes and the

Interesting series of tweets.
I'm surprised by the tweet about Seymour Cray founding Control Data
Corporation. I know that Cray /worked/ for CDC, and left to found Cray

Only F*tran, which we used for predicting race horse results on the
midnight shift. The enterprise app was written in ART418 assembler.
I'm having lots of fun with the ESDI drives, got one running RT11 on the
11/73, and one running NetBSD on the MicroVAX, but then tried the two I

The discussion about 3-phase made me check some documentation.
The drive I remembered that uses 3-phase power is the RP04. I remember a

will try to spin up in the wrong direction, which might partially unscrew the

There should be more /785s out there than plain /780...
IIRC, most /780 were upgraded, as the "old" /780 had some EMC issues
in the field? Am I dreaming this up?
