One of the early Compaq ones.  360K.  Although while that board was 
current, the PC-DOS format was 160K, followed by 320K.  You can do 720K, 
of course.
TWO drives.    I thought that I remembered a version of it with a DC37 for 
external drives, but I might have put in a 5150 board for that.

Has a real NEC 765 chip.  It is unlikely to be able to do FM nor 128 byte 
per sector MFM, and has a nice long blind spot after indes pulse (making 
some complications with reading the first sector of track of some formats)
