Back in the day, I wrote a floppy driver based on the 82077AA for a
board I designed. The 82077AA is long gone and I\'ve been away from
hardware engineering at this level for a while. I am doing a spare time
project where I\'d like to revive the FD driver in conjunction with a
small SBC. I am wondering what the current chip is that is close to
being functionally equivalent to the 82077AA that can actually be bought
today?
I did some searching and found the Microchip FDC37C78-HT but it seems to
be unavailable. There are other FDCs around at the time that were quite
popular (e.g. NEC D765, intel 8272 and of course the WDC FDC) but they
too are long gone/unabtanium. I like the intel 82077AA because it could
interface to a large number of FDCs.
I also am considering to throw a FPGA at it, but that would probably be
more work than I wanted to devote to it....

I\'ll keep searching but in the interim I thought maybe someone here may
have some thoughts/pointers to FDCs that are currently available?
Thanks

I\'d look into the Raspberry pico, with its 10 independant IO processors.
