Hi Klaus,

> how much overhead does the ICD require?

Not too much. The PBP header file ICDDEFS4.BAS reserves a few bytes for the "debug executive" ; ICDRESERVED12 VAR BYTE(12) $5f4, and the ICD2 uses & limits a few options like WDT, LVP, etc, but your ICD2 docs will give you a beter idea of the resources needed.

It's pretty handy. I use the PICDEM 2 Plus, ICD2 & PBP all the time.
