The third-party controllers were most popular on the
Model 1, since the
stock
FDC was SD. There were a few third-party controllers
for the Model III
and
the early Model 4, but they weren't as popular as
the 1793 was more
capable.
The stock Model 1 FDC also had reliability problems
that lead to
third-party
data separator plug-in circuits.
Yep, the M1 data sep was the 1771 internal and that was at best terrible
and WD would tell you that. That lead to the Piggyback card to at least
add a decent data sep. The 1793 came later but was very desirable
as the 35/40track Single sided FD100 or SA400 drives were tiny storage
wise.
