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.
The only Model 1/III/4 that came stock with DS drives was the 4D. Any other
DS setup was third-party. The stock III/4 controllers (both the add-on in
the III and early 4 and the built-in on the gate-array 4) had no problems
with DS drives.
