The P112's floppy controller is the one in the SMSC FDC37C665IR SuperIO chip. The data sheet states it is a 2.88 MB "Licensed CMOS 765B Floppy Disk Controller" and claims 100% IBM compatibility (for what that's worth).

2.8M (it is not "2.88" unless MB is 1024,000) means that it includes a 1000K data transfer rate

765B means essentially the same FDC as PC (NEC 765 based)

Does it also support FM?   125K data transfer rate (TRS80, Early Osborne)
