I'm in the UK so trading probably isn't worth it.

I used to work in the group that produced those (well, wrote the 
software, someone else cut the media, I guess).

I have a set of PSI floppies of roughly that era but mine are RX50s (I 
think: they're in the attic somewhere right now ...).

I don't think I've ever seen PSI software on 8" floppies before.

If you do manage to image them, I'd certainly be interested in a copy.
