Is there a list of part numbers to watch for? I haven't purged my
collection, but except for a large box of Tandy-compatible 3.5" drives
(the one that pumped drive power over the 34-pin cable), what I have
is a random assortment I'd want to check against a list to know which
ones are keepers and which ones are only useful if I wanted to read
DOS floppies on a PC.
Well Teac FD235-F, -HF, -HG, -J are all well-constructed, but there's a
huge variation in PCB configurations, so endorsing any single version is
pretty much an exercise in futility.
My latest favorite is the Samsung SFD-321B. The jumper pads on the PCB
are well-labeled and you can get a datasheet for the drive. Both ready
and disk change are easily accessible and drive selects 0-3 as well as
the In Use output are available as well as 2- and 3-mode operation.
They don't seem to be in short supply, either.
