Topic: Tim Follin's source code archive

Released a few days back it seems, some source dumps off the Follin's Tatung Einstein floppies. Contains some Z80 and 6502 stuff, not sure which exactly. No comments spotted in the files.

Excellent! Only had a quick look so far. This looks promising:

Re: Tim Follin's source code archive

Unfortunately I can't merge FrankT's post into this thread, so as a compromise I moved this into the Sinclair subforum (not ideal since there are non-Speccy drivers in the source dump as well) and closed the other thread. Sorry for the inconvenience.

Anyway, looky over here: https://spectrumcomputing.co.uk/forums/ … p;start=10

Thanks for your hard work polishing these up, FrankT! Alas, if the notes at https://github.com/ZoomTen/chronos-zxbeeper are correct, I don't have very high hopes for the usability of the 5ch player...

I honestly can't wrap my head around the internals of the 5/6ch engine. Very complicated design for the time. Hopefully FrankT will figure it out.

Not really related, but a nice visualization of what is going on for each of the channels: https://www.youtube.com/watch?v=F1e2MOeo5eU

I think we should try to extract at least the sound loop code somehow, and replace everything else with the traditional pattern structure. This way we'll get the iconic sound at least, even though with a high memory consumption.
