The 'pure speculation' was merely because the answerer was not setup at the time with the tools/environment to replicate. It does not mean that the results could not be replicated under any tools/environment however.

It was something like a 4x16 and you inevitably have to make some value judgements in your "display a string" subroutine about what to do when stuff doesn't fit on a line. It only had a quarter K of ram and not much more onboard eeprom so I never tried to display thousands of letters. My eventual strategy was overwriting (keep it small and simple). What do you do with a quarter K? It was basically a very slow beamwidth analyzer for LEDs using a photodiode and a R/C servo. So the 3 dB down aka half power beamwidth of this integrated LED and diffusion lens system measures as X degrees. Kind of important if you're making LED based signs. I believe I was only using about 4 bytes of memory. No need for interrupts as it had a rather advanced hardware timer system that made excellent PWM for driving servos. The world is full of interesting problems that require lots of computation but very little stored state.
