I have damaged the link port in my 83 before, but that prompted a complete comms blackout rather than no response. I actually had to open up my calc and resolder one of the ports joints, as it had fractured. I'm not sure how common this is, but I dropped my calc with a link cable in it, and I  think that jogged the socket out of place a bit...

Hope this helps...

P.S : Anyone out there come up with any ideas re my previous comms problem involving the PC Link???

I would suggest you get the 92 emulator for your pc, and see if you can
get it working that way.
