Data I/O 29B help

[Jay West]

I've got a Data I/O 29b with Unipak2 that is on the fritz. I thought it was 
working, but it's not.

It frequently reads chips right, then 60 seconds later reads different 
values with different checksums. It's sporadic. It never gives any failure 
messages (other than bad verify ram to device). It just doesn't get the 
right values sometimes.

I'm not up on the internals/repair of this unit, nor do I have time at the 
moment and I need a working one ASAP.

Would anyone on the list know a shop that does repair of these units? Or 
maybe be able to ship me a 29B and/or Unipak 2 so I can at least determine 
which major component is ba and get over this hump?

Thanks for any thoughts/advice :|
