Cromemco: XX4306
------
Thanks for chiming in Mike, could use all the datapoints we can get. Can you
elucidate which models of cromemco XX4306 works on? I'm not familiar with
those machines other than I know there was a 2 and a 3... something about Z
comes to mind... And on a specific model, are you able to try/confirm XX4306
on multiple machines?
AFAIK all models using a tubular Ace key used that same number.
They were used in the various versions of the System One and System Three
(CS-1, CS-3, CS-100); Z systems didn't have keylocks, and the other (later)
CS-x00 (200, 300 and 400) series used the KABA flat keys with dimples
(which were also all the same number AFAIK, EB0001).

Some models also used 'normal' keys for access to the card cage etc.
Also - before we get too wide on the systems
tracked... the "standard" ace
key had a barrel outer diameter of 0.375" and 7 positions. I am aware of 2
other variants that had different barrel OD's and different number of
positions.
So mike - what's the OD of your key, and is it 7 positions (concave
semi-circles around the key)?
0.375", 7 positions. If I can find my micrometer I'll measure them; wasn't
there an old thread about Ace key codes?
