Does this count?


Metal dash board on my old 68 Ford truck has adhesive backed numbers stuck to it. Every tank of gas, the driver is supposed to move magnet up one digit.

The odometer quit working back in the late 70s, this is how we keep track of when to change the oil.

01 Add gas? If Y goto 02, if N goto 01
02 increment register 1, +1
03 if register 1 > or = 10 CHANGE OIL else goto 01
04 0 sto register 1
05 goto 01


Anyhow, that's how it's supposed to work.

I'm impressed that the magnet and numbers can run a BASIC interpreter. Though you might want to look into Fortran for that kind of scientific processing.
