Hi list,
just want to share. :D
Six years ago I bought a midi2sds2 from Paul (still here?). I assembled
it and everything worked just fine except one trigger out. The problem
was a mistake when one IC was programmed and I received a replacement
and tested the thing and it worked great. I planned to modify it for
SDS-V (stronger trigger output). In the meantime I thought it stupid to
waste the IC that had seven working outputs (and also the 19" housing
which was salvaged from another project and it had 16 LEDs mounted
already) so I began the work on a breadboard clone. But then a divorce,
depression and reality dawned on me and the project was shelved. :S
Yesterday I dug it out, started retracing wires, looked in disgust at my
old solder joints (amazing how such skills improve in six years!) and
corrected not just a few mistakes.
It still isn't pretty but it at least went through the start sequence a
few minutes ago with blinking LEDs and no burnt ICs.
And nooooow... I found the place where you can still get them. :-o

messy to look at. Beware of eye damage.
Paul, if you're still here, what are roughly the margins for the PSU
feed? I don't remember and cannot find anything on the subject among my
old mails.
