Sinclair ZX80 / ZX81 / Z88 Forums

Years ago I played around with that program. But it ran faster than the music. Is it designed for a 50 Hz or a 60 Hz Zeddy? Maybe the speed was not OK, because I had used a patched rom (for faster BASIC FOR/NEXT) in my Zeddy. Maybe nowadays, when using a ZX81x2 rom, the turntable must run at 45 rpm...
