Here's the specs I could read on the drive itself.
Mitsubishi /Sankyo MF355C - 58UJ
Date: 1991

There are lots of jumpers. Here's the ones I could read/figure out
TPA 1 2 3 4 = 0
DS = 0
LD/HD = HD  -- against better advice on this list I'm using HD 1.44Mb 
IBM formatted discs but with the hole filled in. Works fine for me so 
far. I don't have any DD 3.5" discs so I haven't tried adjusting this 
jumper yet.
DC = 1
SR = 0
MM = 1
MS = 0
IS = 1
IU = 0
HO = 0
SW = 1
