I have been messing with picstart again. I use it mainly for isp programming
often it fails.
so I got fed up with this and started to wonder why.
I have always used a 10k pull up on mclr and a diode.
http://www.dessy.ru/kitlab/PICSTARTER+.html on pins 1/ 4/ 14/ 32/ 40


from there I got a schematic and noticed that mclr is pulled low with a 5.1k
so I my pull-up
is now 33k
because I think the 10k was not being pulled low enough and not allowing pic
to reset.

What value resistor do you use as a pull up on mclr ?
