Sinclair ZX80 / ZX81 / Z88 Forums

I don't think that's a fast-load, it sounds like a normal Speccy save to me... but it's very poor quality. Is there any way you could record the WAV file again with the cassette volume turned down a bit?

Looks great to me!

PAUSE [anything larger] will wait forever.

The old classic was "PAUSE 4E4" which fulfills the "anything larger" criteria and can (sort of) be pronounced "pause for ever".

Sorry about the delays on this (and general lack of input to the forum!), I've finally got some time off coming up so I'll be able to catch up on some ZX stuff I have in mind...

What we need here is a Like button!

Ah - well, my ZX81 in the 80s didn't produce the sound of snow... when properly tuned, it was very quiet with a low-volume buzz. If you detuned slightly, the buzz was louder and would change as things were printed to the screen e.g. as a listing was produced. When in FAST mode, the buzz would switch...

Isn't there also a diode that lets the ZX81 know whether it's 60Hz or 50Hz? You can PEEK a system variable to find out which system it is, so it's definitely not just a matter of the modulator alone.

Nifty!

In that screen grab, why is MUSIC EDUCATOR 1 enclosed in single-quotes?
