Since I'm going to get some keys made, I looked up Jay's posting of 
keys, three of which we verified from his formulas.

Here is the posting from March 2016

Here are the formulas he posted then.  I thought there were more 
discussions about making an archival page, but I did not go on and look 
up whether it was made up or not.

As Ethan said, somewhere there is also a 3d print STD file I believe, 
but the locksmith numbers are better.

FYI - the key codes I measured previously for Data General and HP have been
cut, tested, and verified. Amazingly, my measurements were correct. So to

Code: 5173757
Use: DEC PDP-8 (all varieties), PDP-11 machines that do not use an ACE blank
(11/24, 11/44)

Code: 1353757
Use: Data General Nova (800,1200,1220,2,3) Eclipse (S/130,S/200)

Code: 4557457
Use: Hewlett-Packard 2100A/2100S

NOTE: The codes above are listed 7-1, and all key cuts are center offset.

Still unconfirmed or need more information:

Cromemco: XX4306
Code: (Mike Stein was going to measure his cuts)
Use: Cromemco Systems CS-1/CS-3/CS-100
