Hello,

After almost 24 hours my message has not appered, so I resend it:


Hello all,

I have some problems programming pic12c508 DIL chips. From one tube (60
pcs), 18 didnt work after programming, thats 30%, and I have no idea what
could be wrong.

I have programmed all in same way, with same source code, and on same PC...
I am using win3.11, picstart plus programmer and mplab, all chips are
programmed ok. I suspect the internal osc. to be the problem (Have not made
any tests), all chips are programmed with internal masterclear and int.
osc. (source uses int. osc.)

Anybody have had the same problem ????
What could be wrong here..


best regards,
tobias
