[Premium-Rx] OT? REGCO Baseband converter

[Glenn Little WB4UIV]

I just obtained a REGCO RG-7310D base band converter.
This was part of RF Grimm Co in Rockville Md.
This is a remote controllable microprocessor controlled converter that 
should work as a HF receiver with the correct frontend filters.

I know that it will turn on and the display goes from 0 to just under 16 
MHz.
It is 4 channels.
Has F108Z12 filter, 106 KHz LSB.
Also has crystals filters with 24 KHz BW.
Weighs 45 pounds.
Firmware dated early 1980s.

Would anyone have any data on this?
Any help appreciated.
