Hi,

I recently had to try and troubleshoot a faulty SDS7 voice card, but it was difficult because the SDS7 service manual that is freely available has very poor quality (virtually unreadable) schematics for the actual voice boards, and the other schematics are not much better.

Does anyone know if better quality schematics exist for the SDS7 and are they available anywhere? I would be happy to pay.

Also, I've asked before but no harm in asking again - does anyone have an SDS6/7 memory cartridge for sale?

Cheers, vout
