Thanks!!  Staring at it, I feel like a total doofus... I guess that's
what happens when one doesn't get the time to work properly.

I had to massage your patch to fit into the latest source base; could
you please try out 3.52-pre8 to make sure it works as intended?

(I have also downloaded your disk image and added it to my collection.
It booted, but gave me an "invalid opcode" error after loading DOSLFN --
looks like it might be related to the program "tcpinfo".  Not sure if
that is expected or not.)
