The one I have borrowed has software 2.0 on it. I see above you guys have 1.2 and 2.2.
Here's the 2.0 ROM.
I'm still looking for a manual and PSU specifications for "The Interface" by Kantronics. The sidecar doesn't need a PSU, but "The Interface" terminal unit does need one. Also need guidance on hooking it up to my shortwave so I can see if it still decodes RTTY and CW.
