Re: Trouble with Pocket Programmer

[Shannen Durphey <shannen@grolen.com>]

I've had best luck using Fileprom.exe.  My PP is at the shop now, so I
can't check the power supply voltage.  Basic question, is the chip
installed in the socket correctly?  Also, with the P type machines,
make sure your parallel port type is set to standard, if you can do
that.  I can't use my PP on the laptop when it's in the docking
station because the laptop defaults to ecp port.

Each time I do a check sum calculation on a chip it is different.  I have no idea for sure what is causing my problem.  I've tried the p.p. on my PII-300 laptop, my 286 laptop and my PII-350 PC.  It will not work correctly with any of them.  I did notice that the power supply I got with the unit is putting out about 14V D.C. on my multi-meter.  That is quite a bit higer than the 9V it's suppose to be putting out.  I'm gonna pick up a new P.S. at Radio Shack tomorrow and see what happens.  My best guess is either the high voltage is messing with the p.p. or the p.p. is already fried because of it.  If I don't have any luck, I'll get ahold of the place who built the p.p. (the company that builds it is only 15 miles from me) and see what they have to say.  I thought maybe some of you may have some ideas.
