Dan:

Thanks for clearing that up. How do I read the OSC calibration info using the
ProPic software.

Shahid,
  May all your problems be of this magnitude !

3FFF is exactly what an erased part should read.

The PIC's read all 1's until programmed.  In other
words programming really writes zero's

Just scroll the data screen and look at the last position, this is the
calibration value.

Do a normal read, and check out 1FFh (if you're using a 12C508), or 3FFh
(12C509). The calibration value is stored as a MOVLW.
Bits 4-7 represents the calibration value. (if reading 3CA0h), the cal.
value is 'A'...

The last position reads 3FFF as well and this a never used 12C509. Are
there any other tests I can perform to see if the programmer is I/Oing data
to the pic properly?

Well, looks like I have a bad or completely erased (w/o cal info) 12C509 as
I get 3FFF for the last entry as well.

I tested the programmer by sticking in a 1K resistor between GP0 and GP1
after starting the read function. From the point I stick the resistor
onwards, all the data is read as 0000 which makes sense 'cause the software
looks for the data right after the downward transition of the clock.

So at this point, either the chip is not going into program mode or its
bad.

Anyway, thanks for everyones help on this.

Shahid
