Turning this into a slog: gave UEF a more appropriate name, got as far as now having to decide what to do about ROMs as to structure. I guess they're machine specific, so specific classes?

This has now successfully loaded its first PRG-as-a-tape.

This gets through loading the first(/only?) copy. I tried repeating it with a bit-flipped header, now I'm trying repeating the header with a different file type. More documentation searching to do, I guess.

Fixed parity: now calculated from the actual byte and works the other way around. The Vic now believes it is loading the actual program. So I guess bytes, headers and the lead-in is working.

This proves that bytes are being deposited properly. For the first 36 anyway, and with no announcement.

Lengths I'd taken seem to have been for dipoles, not single poles. So I just doubled the clock rate. Also I was producing each dipole as high then low, when they should probably be low then high. The Vic now at least recognises that something is happening on the tape.

I've obviously misunderstood something as, as far as I'm concerned, this should at least get me a 'LOADING'.

I'm starting to make a little headway, I think: this performs lead-ins and countdowns, though with no actual data or anything as helpful as that.

This likely forms the Commodore dipoles correctly. It just stays stuck in leader tone forever is all.

Made sufficient changes for the Vic itself to believe it can recast a PRG as a tape and insert it that way. So now the ball is in the court of: how the heck are Commodore tapes encoded?

With silence and high tone implemented, this may well hit a large proportion of existing files.
