Gentle reader:

I have an Mac IIcx that shows some anolomous behaviour that, in short,
prevents it from using localTalk, and I hope some reader may have an
insight that explains the problem. Here's the evidence:

When connected to a net it does not show anything in the chooser, 
although connected directly to a lw it seems to work.  It does not
seem to be a physical problem, because I can run "peek" from it, and
it shows the net traffic correctly. However, when I peek at it from
another machine while it runs chooser, the packets are garbled (this
is also on a 2 node net.). It neither runs nor appears on the 
Farralon NetCheck desk accessory. 

When booted with the system on a floppy, the same problem appears. The
next thing I will try is reformating the hard disk, to remove the last
vestige of doubt about system software being the cause.

My current suspicions are:

If it receives via peek, have I ruled out any hardware faults, or
is there an additional test of the localTalk hardware that would 
clear things up at this level?

Is there anything different about the cx, in hardware or ROM that 
might explain this?

MIght there be something screwed up with  NBP (for the chooser, and
checkNet) that might not be diagnosed by booting off a system on
floppy?

Any insights will be greatly appreciated.
