It doesn't use the 4869 units, they came out later with the PS/2 line of
machines ....just everyday floppies wired as if the ribbon cable came out of the
case where the 37D connector is. I did the same with my Sanyo MBC-555 years ago,
making my own external case with the 2 externals in it. The 4869 would work with
a repinning, and a pass-through to another drive. Of course you have to jumper
the externals as DS2 and DS3 (on drives that jumper from DS0 to DS3)
