KGB-PRK memory expansion/FPU board?

[Arcade]

I got a nice surprise opening up a Super off Yahoo Japan-- two expansion cards I wasn't expecting!

One is the "KGB-PRK" (from "BASIC House"?) which looks like it has 2Mbytes RAM and a 16MHz 68881 FPU.  (the other was an I.O. Data 4M expansion)

Questions:

1) Is the KGB-PRK card documented anywhere?  (I found the info on the KGB-PRK II, but the jumpers and stuff on this one appear different.)
2) Should I take some high res photos/scans for the archive here?

Thanks!

 Hi Arcade !

Should I take some high res photos/scans for the archive here?

Yes, please. Hi-res pics from both sides would be very beneficial.

Keep the scene alive !
