One place I worked skimped on the ROM monitor so the TTY printed "half-ascii" for hex: 0-9 and ":;<=>?" instead of A-F since that's just 30-3F hex (060 - 077 octal). I called half-assed key.

*1: there were many ways to make ROM before chips, such as arrays of diodes, rope memory, etc. but that was really expensive and took a lot of space
