I can vouch for the Intel 82077 chip. It really is a floppy controller on one chip and requires very little glue to make it work. The software is made much easier since it supports multi-sector transfers and implied seeks. You can tuirn off the 765-style polling of drives with a command. Formatting is simpler than the old WD chips: you make a buffer with 4 bytes per sector instead of hundreds and the chip does the rest. -- : Phone: (502) 425 9560 << Steven Weller >> Fax: (502) 426 3944 : : Windsor Systems, 2407 Lime Kiln Lane, Louisville, KY, 40222 USA : : "A substance almost, but not quite, entirely unlike tea" : : stevenw@disk.UUCP or uunet!ukma!corpane!disk!stevenw :
