TEAC FD-55GFR 5.25" Floppy Configuration for NGEN/AWS 300 RPM vs Standard PC 360 RPM - "A Tale of Two TEACs"
Jump directly to JUMPERS (pun intended)
While most of these drives operated in the world as 1.2Mb. But with the Convergent Technologies AWS & NGEN machines, it's a different story. Those systems use "Quad Density", which is basically 80 tracks (or 77 in this case, where the last 3 are just ignored), and the drive RPM runs slower, at 300 rpm instead of 360 rpm.
But what jumper(s) change the drive speed from the default 360 rpm down to 300 rpm?
All manuals we find for the TEAC FD-55G-series show radically different jumper positions and names, so they are unfortunately, not helpful. But we still want to know, so through real-life comparison and process of elimination, we're going to find out!
First, the NGEN/AWS configurations, running 300 rpm:
Now compare to the "Normal" PC Configurations running 360 rpm
There's a LOT fewer jumpers on the Standard PC drive running 360 rpm
Here's the differences highlighted:
Note some of the more confusing jumper labeling:
Note to Self: Edit below image, some jumpers are labeled wrong
Notice that some of these jumpers used for the NGEN/AWS aren't even INSTALLED on this drive!

First privately owned Convergent Technologies IWS (Integrated Work Station) found!
A friend of ours had acquired this many years ago, and recently shared these pics. We have plans to collaborate on a full restoration, and hopefully a "clustering" operation (early networking) between this IWS, our AWS, & NGEN systems!
