Quote - I wish I still had some of my 16-bit Spectrum artwork from....oooh, 1982?

Quote - Must've been a pretty damn unique Speccy, then.  Mine was 8 bit.

Paul means 16 colour - there was one bit per colour, and a brightness bit, hence four bit colour. Of course there were only 15 colours in reality, since bright black is indistinguishable from dark black. :)

More limiting, each 8 x 8 pixel square could have only two colours used within its boundaries: one for ink, and one for paper. That's how we managed to get a huge 256x192 pixel display into only 6,912 bytes of video RAM.

Tell that to the kids. :-)
