Not much going on with OLDsynth & OLDsynthS (?)
Everyone quit building? heh heh
(know this can't B true)
Re: Joysticks-----
As i recall, Atari joysticks were excentially 4 momentary
buttons; Apple joys were pots that controlled a timing
capacator; ; the 6502 read the "time"; sort of like PWM
in reverse(?)
Lots of electronic surplus compainies have 2-axis JSs around;
the resistor(pot) values vary from say 5K to 100K;
put a controlled amt of V in the top; other side to GND;
Or, use resistors top and bottom to "range" it in;
Or, use switches to move range up and down;
first decide what U want the end2end voltage swing 2 B;
if U dedicate 1 or 2 LM317s for the JS's pwr sup, U don't
have to worry about range switches;
AFN
