Re: SOUND and ENVELOPE

So the sound commands for the original PC's (with the chip) were the same as the current version? I guess that's what throws me for a loop, since with the PC's I had in those days (Commodore) one had the addresses of the chip registers, and their function, but nothing close to as formalized. Was that some of the fabled Sophie's work ?

If you are asking whether the SOUND and ENVELOPE statements were in the original BBC Micro version of BBC BASIC, yes they were. They have been there from the start.

That wouldn't have been much use on the BBC Micro, because the sound chip it used was 'dumb' (no kind of envelope control, for example). ENVELOPE is entirely done in software, AFAIK.

Unlikely. I don't think she worked on the Operating System (MOS) ROM at all. More probably Paul Bond.
