Key for IBM 9370 - 20

I think there was a long thread about this in the DEC section of the VCFED site. Sticky, so at the top of the forum.?

I'm including a quote from a post by Jay on the subject.? I need to get the information on measuring the depths of the cuts, as the postings I've found don't mention how the depths are measured for each value. I have an ACE key for an IBM 9370 mod 20 I'm measuring. Found a post by Jay from 2016 Jay West jwest at classiccmp.org Fri Mar 18 15:57:30 CDT 2016 ------------------------------------------------------------------------ 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 summarize: XX2247 Code: 5173757 Use: DEC PDP-8 (all varieties), PDP-11 machines that do not use an ACE blank (11/24, 11/44) Anyone have a reference on the depths of the Code values? There's another post with depths, but not explicitly calling out what each number equates to. My master has a DND legend on the back, so I will need to get a copy cut and tested via codes, and will publish it when I find out that it works. Dennis Boone post: Allegedly Control Data used a National C415A on Network Processing Unit cabinets in the late 70s, early 80s. That's an Ilco 1069-N, cuts are 12343 from bow to tip. Cut spacings are .156 .249 .342 .435 .528. Depths are 1=.250 2=.225 3=.200 4=.175. The Boone post has numbers, but they make no sense WRT the post Jay posted (which has 7 depth values) Also need to know if metric or inches.
