Default singer 998 Serger

Has anyone come across one of these rascals?
I called Singer Industrial Division, and they had never heard of it. I did find a parts diagram for a model that was close. It does either three threads or 5 threads. The 4th and 5th threads make a second row of stitching with a chain stitch on the bottom.
It is belt driven from a huge motor under the table that has a clutch brake operated by the left foot pedal. One can make it go slowly, but it is tricky, it loves to go FAST. The right foot pedal lifts the pressure foot.
I have studied it and don't see any way of changing the stitch patterns.
Most of the threads are fed through tubes.

This is a sample of how the stitching comes out.

That's quite the industrial serger!

Does the bottom, left side open? On some old sergers there's a knob under there to loosen, then move the stitch length indicator, then re-tighten the knob.

It should have a cutting width adjustment, which is probably just a screw under the front of the needle plate. And tension adjustments for each thread.
