Old BAL. Base Displacement.

My favorite instructions were ICM SCM and later BALS.

ICM SCM I don't know what it is. BAL was called ALC in school and where I worked. I had a TI calculator with hex and octal (and decimal) which was very handy (didn't use octal except for fun) although I learned to add and subtract (not multiply and divide) in hex the manual way.

I wasn't very forward thinking. One instructor used to tell us things like someday we would order groceries by computer and have them delivered. Bet he didn't fortell the iphone though. Maybe he did.
