Now, come on... If you're in the 40-50 range, you should have put octal
before hex. :p

IBM S/360 definitely preferred hex.  And EBCDIC.


Strictly an artifact of it's EBCDIC nature, as a matter of fact...

The BCD in EBCDIC stands for Binary Coded Decimal which inherently
requires Hex.

In fact, if you compare punched cards to EBCDIC, you'll find some remarkable
similarities...

For example C1 (12 1) is A (Hollerith A is a 12 punch plus a 1 punch).
