Also, whilst you were saving up for a disk system, Gemini had RP/M which allowed you to develop CP/M software with storage on cassette tape!
RP/M was a 'cp/mified' monitor that supported most bdos calls such that simple CP/M programs wouldnt know the difference.
Once an application was loaded (say MBASIC etc), RP/M allowed you to stream just one file on tape.
I very much liked Polydos, one of my long term to-dos is to un CP/M my NASCOM 2 and re-install Polydos
