[sdiy] Christmas Projects

[Dave Brown]

I'm trying to restore up a 1984 Wersimatic CX-2 Digital Drum machine.
Someone else had worked on this previously and replaced bad parts with wrong
parts and then tried to modify the circuit to make them work!  Interconnect
cables and connectors have melted so obviously the current limit didn't do
much.   I've now got the power supply up and running and powered on all the
logic.  No shorts and the 7 segment display changes!  Everything's in German
and there is no interconnect diagram.  It is a plug-in card cage so I can't
access any boards and it appears there were many different options and
configurations with differing plug-ins.  Should be loads of fun.

And then I have a Fender 2235 power amp with most all the outputs and
drivers shorted ...

make the thing Arduino Compatable.
