[sdiy] Jupiter 4 memoy issues

[Gil W.]

I just got a JP4 which is in a very good condition
overall. It has one power transistor floating with not
heat sinking and was totally fried, but still was
found to work !

Anyway, I got a few issues -

1. The memory protection switch act like a momentary
switch (once you push it, the led lights up, then if
you release it it will go back to the initial mode,
and led turns off). This way, you're only able to
write a patch if you push both the Write and Protect
buttons, AND the patch number... Is that by design or
is the Protect switch defected ?

2. When I save to either memory location 1 OR 2, it
will save the patch to both 1 AND 2.... any idea what
could cause that ?

Thanks all !
