Feature request: 2031 drive support

[rhester72]

This is probably a bit of a stretch goal laughs, but if we could get 2031 drive support (which is very, very close to that of the 1541, even using the same disk format!), that would make data transfer (and especially saving content natively from the PET!) much, much easier.

I'm hoping it's not a huge ask and can leverage most of the 1541 support already built into the C64 core...it's certainly a nice-to-have, not a must-have.

It is worth noting this used the IEEE-488 bus and not the later proprietary Commodore serial bus...which made the drive faster, but may also make implementation/integration more complex.

Generally speaking, PET core exists more for specific software (mostly games). I think more advanced Commodore computers like VIC20, C16 and especially C64 are more suitable for some fan programming. All of them have the same CPU and cover the whole PET functionality. So from my point of view further PET development is kind of pointless.
But of course if there is a big fan of PET computers wanting to extend it, then he is welcome to do it, i'll accept PRs. Probably C1541 code can be re-used for PET.
I see you are very active, so you can try to develop PET core to more advanced one. Even if you don't know FPGA programming, you can learn it. MiSTer is hobby project where we learn something new every time :)
