Did any of the Sinclair ZX Spectrum users had any experience with extension units for plugging in a microcasette recorder and a printer?
When I was tired of using those noisy tape casettes I'd use those microcasettes which were like mini-mini-floppy drives :)
If only I was able to find of those special cartdridges in Istanbul, I think I'd break into games and try to apply the techniques given in Sinclair User. (Commodore and Amiga users were lucky in this respect)
