Compass X-70 and X-80

[Merc]

Does anyone have any info on the Compass X-70 or X-80? I just purchased one of each and could use a schematic. If not available, these 2 will become my next projects to take apart and draw schematics of over the next few months.

Thanks,

Blown Circuit

I have an X-70 with a blown circuit because the idiot that I am I connected the battery plug in reverse polarity when I had the box apart. Any ideas?
