Hi Imre,

Thanx for the feedback. The wiring of my kit is actually different from the
default settings in the s/w. However, I changed the settings to indicate the
right Data In, Data Out, Clk etc.

I did re-wire the circuit and go thru the verification steps. everything is
ok, except whten I connect the parallel port, when pin 5 (Vpp) goes low. It
does not change regardless what the s/w is set to.

Thru DEBUG, the parallel port base addr is 0378. I sent all 1's to the port,
but it measures low. This makes me suspicious about my parallel port.
However, I had a brother laser printer two weeks ago and it worked fine.

Any suggestions?

Kevin,
I actually blow my transistor too.

Thanx
Alaa

ok. What I noticed is the that D3 (pin 5) on the parallel port is always
low, which makes the 13.4V voltage appear all the time on /MCLR, hence
preventing correct setup.
