How many other random constants do you remember because of being a programmer?

That limitation seems to have been ignored by many respondants. Oh well...

Hmmm...let's see:

• 512x512 - the size of a PLATO screen in pixels
• 60 bits per word, 10 characters per word - memory characteristics of a CDC Cyber
• 128 - the number of characters in a charset
• 10 - the number of armies you have to bomb to get a kill in empire
• 8x16 - the character cell on PLATO
