Vintage Simmons Drums (UK) Users Group

Hi to the members...
I`m new here, my name is Sergio, living in Barcelona.
I recently acquired a SDS6 controller with a very serious damage
due to the battery corrosion. I have cleaned all, replaced bad
traces and some ICs in the affected area (even the 6522 VIA), but
it remains dead. The control panel has no effect at all and the
LEDs shows different patterns each time I switch on the unit.
I could to continue with the repair but the schematics would be
very useful to that.
There are some chances to find them on internet?
Have anyone of you that kind of documents?
I will be very grateful if you could help me with this problem.
My best regards
Sergio
PD: sorry about my english :)

Hello Sergio,
I can send you the schematics I once got from former simmons serviceman Ralph Reichen. But they are not complete: The schematic of the CPU board is still missing. And nobody of our group is sharing THAT with me. May be today ;-) ??
Send your email adress to: buchnerelectronics@...
I will send you what I've got.

Hi all,

I wondered if anyone had yet found the elusive SDS6 CPU board schematic and was prepared to share it (thanks Michael for the other schems !) ? If not, could anyone with a 6 let me know what IC15 is please ?

Thanks, Phil.

Sure, I´ll go and check it.
