i wrote a manual relative to the printer port .. a small portion is on the
web;

http://www.nmsu.edu/~ET/ETTI/review/phajun96

the manual itself shows how to use an ADC0804 .. the 8 input problem is
handled by gating only 4 bits at a time to the status port using a 74xx241
.. speed is limited by the A/D .. better than 1000 samples per second ..

i have a student, Christine Samuels, who has interfaced an ADC0838 which
is a serial device, but she is using the printer port .. hopefully, she
will have it on her web page this next week .. her web page may be
accessed from mine ..

although the manual is written using C, it is pretty generic and it should
be simple to adapt the code to BASIC ..
