Microbee Poke and Peek colour registers for color basic 6.35p - taren0305 - 09-09-2026

Microbee Colour BASIC — colour variables

Current foreground colour

Code:
POKE 156,n

Current background colour

Code:
POKE 157,n

Half-intensity background

Code:
POKE 158,n

I was curious where the microbee stored its colour address, so went on a hunt. its same as poke 646,? on commodore64.. much faster then color ??

When you use the color /colour /colourb / colorb commands- actually the same speed as using POKE as the BASIC interpreter resolves it immediately to the actual POKE command. Its an interesting quirk in how microworld BASIC was developed.

(maybe it is ubee but using poke 100+58,2 and color 1+1 seems to be slightly different on a stopwatch. and poke 100+58 stops the interpreter changing the command back to color) run it through a simple loop. for i=1 to 1000: poke 100+58,2 vs color 1+1: next i
