Added logic to try to spot when the first program is BASIC and, if so, what the correct memory model is, then to get that information to the Vic. Though it currently then gets overwritten by the view controller. Grrrr.

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.

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?

Turned the 6560 into an ordinary template, similar to the rest of the project, albeit right now with a fairly shonky internal implementation. Fixed a Mac-specific interface sizing issue.

Made a first stab at having automatic loading be optional. But things are currently arranged such that the machine options are communicated too late to have an effect. So work to do.

Converted the 6560 fully into a template; worked on allowing the typer to run at a much faster rate where hardware has some trigger by which it can request the next key.

Furthered fleshing out of the 1540. Though it doesn't yet receive a ROM so won't even attempt to do anything meaningful.
