CliveS education
still have both the ZX81(s) & that printer in my 'museum'. was a major forward step to learn 'Basic' programming. was ~$30 CDN back then so cheap indeed. also have a collection of utilities & games including the loved Flight Simulator. most valuable though was(is) the tape (yep-cassette) ZX ASSEMBLER 16K . I'm an inventor.. & need servo software that will react in 'real time'.. so, although a lengthy pain to write.. assember works fastest. thanks Clive !
