I am playing with a simple ADC0804 A/D converter.  But I don't have much
data about it. I have enough schematics to let me know what the pin outs
are but thats it.  I am trying to use my PC(XT)'s paralle port to read the
8-bits information from the chip.  I have had some luck reading in from the
OUTPUT lines on the parallel port (i.e. I am breaking some rules ... I guess?).
But this is not working perfectly yet.  I am using transisitors to drive the
port (letting the A/D drive the transistors as switches, then use these to
drive the tri-state parallel port).  Its acting like when it see more then 4
or 5 0 bits, well ... it starts messing up, like maybe its drawing too much
current or somthing?

Any body beed doen this road before?  Any body got a better way of designing
an A/D ==> pc system?

Thanks!
