Color of 4bit? only a slight increase. Often acheivable in 1 instruction. Limit of 2 colors in 8x8 block on ZX81[1]

- pvg 17y agoI suppose if 'just about everything you said to support your point is wrong' is 'helping you', there's probably not much left to discuss.
- andybak 17y agoYou're linking to information on a ZX Spectrum which is not a ZX81. The ZX81 had a monochrome character mapped display with no pixel access (well - there were tricks that could sort of give you pixel access but they came much later than the time 1k chess was written)
- tezza 17y agoSorry about that... i didn't mention colour depth originally, someone else brought it up (trying to look smart). 6502 was my platform, so I missed the exact Z* platform... I was sharing general info on assembly for 8bit, not specific to one platform (ZX81). This seems to have incensed some people who took a narrow view on what sort of comment was permitted.
