KJ Instruments Model 506 Disk Drive Analyzer

[Vintage Computer Festival]

I picked up a KJ Instruments Model 506 Disk Drive Analyzer.  It's a tester
for MFM drives.  On the front are the data and power connectors for a
standard MFM drive, plus knobs, switches, LED displays, etc.  On the back
are two DB-25 connectors.

Has anyone got a manual by some remote chance?  Has anyone ever used one
of these?
