I learned hex as a result of memorising the bit patterns associated with the strings necessary to define 8x8 UDG blocks, e.g. Without that, printing strings to the screen was a rather tortuous affair involving GOSUB routines and FOR NEXT loops calling HCHAR() (don't ask).Īnd then there were the UDG's (User Defined Graphics for people who didn't grow up in the 80's - you might also need to look up "sprite" :) ).

A lot of my extended family worked at TI in Bedford (UK) and when they EOL'd the '99 staff were able to pick one up for chump change, so we got one through an uncle still working there.
