Any plan to support the floppy disk for the NEC PC-6xxx series?

The FDC chip is unknown, although I'd be fairly surprised if it wasn't an NEC765.

I am in contact with the Japanese NEC-PC6xxx emulator programmer.
Please tell me which kind of informations do you need.

Working on DEC RT-11 and ZX Spectrum TR-DOS filesystem support in imgtool, found a few bugs/missing features along the way when disk image is a td0/dsk/etc (i.e. not a sector image) -- f.e. floppy_read(_indexed)_sector won't return an error if the sector has bad data, you have to check this via floppy_get_indexed_sector_info

Thanks Anna! So PC-60xx FDC is an NEC765 behind an i8049 sub-CPU and 8255 PPI.

Esubi-san also answered.
The PC-6031 is very similar to the external drive for the PC-88xx series.
Like the PC-8031, PC-80S31, etc.

Ahh, so if we support the PC-80x31 we can use it on both systems. Handy.
