Hello all.  I have built a stingy person's version of AN589.  The power
supply switching side seems to be ok with multimeter tests.  Assuming
the software by Andrew Ermington is correct, i suspect a problem with
data/clock lines that is causing my problem : failure to get the damn thing
working.  I may have also blown the pic, but its a shocking thought
and so lets just pretend we haven't thought of that yet.
        I have not used a 74LS244 (stinginess) because they cost too much
and i think i'm a pretty  smart guy.  Instead, to isolate the data lines
on the printer port and the pic, i have used a 10k resistor.  This is
supposed to replace the tri-state buffer of the '244.  The data into the
printer port is connected directly to the pic.  The clock line from
the printer port also goes straight to the pic.  I have not used
any of these tri-stating features because of the cost and i really am not
worried about programming in-circuit, just programming would be fine.
Andrew Ermingtons software says that its programming and says that it
has verified and blown fuses (takes 62seconds) from win 95.  So assuming
that the software can check it out, there can't be any problem with the
clock/data lines, right?  Does anyone have experience with this programmer?
thank you.
