The base system as supplied had 1 KB (KB) of RAM. This RAM was used to hold the computer's system variables, the screen image, and any programs and data. The screen was text only, 32 characters wide by 24 high. Blocky graphics with a resolution of 64 by 48 pixels were possible by the use of the PLOT command, which selected among a set of 16 graphics characters. The ZX81 used a resizable display-file (screen buffer) meaning that it could be expanded or shrunk depending on the amount of installed memory and the amount of free space at the moment.
About Us
Rikworkshop is a freelance operation run by 'moi', Patrick (aka RikkU). I have always been driven by creative (and possibly unorthodox) designs, as well as having experienced the IT evolution since the early days when Sinclair Spectrum's, Atari Commodore's and Acorn BBC's were the ultimate WoW factor. Not to mention HP MPE mini computers which had to be booted through a sequence of 1/0 switches with an array of 9 x 320Mb winchester drives the size of a modern automatic washing machine!
[Apologies to generation-Y who cannot comprehend what an effort it was to hand-type an entire program into 1Kb of RAM in order to play a game .. every time we wanted to play!].
I'm currently reading for my Masters in Business Administration at Henley-Reading business school .. my thesis being focused on Knowledge Management and Sharing, a subject very much to my heart as I truly believe that sharing knowledge (vs hoarding it) provides a unique competitive advantage in practically any market. This ties in very much with the HR function of course .. but that's another topic which I'd rather not go into here.
Once touching on the subject of knowledge sharing, a special thanks to my buddy Owen Cutajar for having been a continuous inspiration through the selfless sharing of his experiences and unfathomable knowledge over the years. Grazzi !
