DOCS FOR THIS DIGITIZER
-----------------------
This digitizer should work as well
for you as it does for me. The circuit
itself can be fitted on a 1.50 x 2.50
piece of perf board. Although parts
placement isnt critical, the arrangement
in the drawing is what I found to work
best for me. The board and all components
will fit into a small project box you can
get from radio shack for about $2.95 .
Parts are easy to find, but if you cant
seem to find the A/D chip, the ADC 0804
will work ok too. I used the ECG chip
cause the cost was around $4.00 .
Make sure you pay attention to the wiring
or your computer or chips may be damaged.
If your not mechanically or electronically
inclined, find someone that is, or send me
a money order for $35.00 and I'll build you
one and mail it to you express mail.
Oh yeah, I didnt design the thing, but i did
improve the one that I got the design from
since it had been poorly drawn and the parts
values were totally out of range for the amiga
to communicate with. (really guys, 47Mhz is a
little to fast for the amigas clock to try and
keep up with.)
