[sdiy] ASM-1 design

[Laurie Biddulph]

Hello and thanks to everyone who, so far, have responded to my request fro feedback on the ASM-Genie and new ASM-1 pcb.

Results so far:-

  a.. Upgrade ASM-1 pcb to include all documented component omissions and improved track layout
  b.. Add triangle output to VCOs
  c.. MIDI-CV to remain as a separate pcb
  d.. Power supply to stay as a separate pcb
  e.. Updated block diagram and front panel layout which now shows 3.5mm jacks for expansion and additional inter-module linking
  f.. Ground planes will be added. Appreciate this makes pcb less modifiable but the benefits far outweigh this loss
  g.. SMD option for Tempcos dropped.
  h.. Terminal pitch changed to 0.1" to allow for wider range of connectors. Board uses 12-way, 8-way, 4-way and 3-way connectors.
  i.. All mandatory pots are now also bought out through 3-way 0.1" connectors allowing pots to be 3-wired back to board or wired at the panel where less than 3 wires are needed
Updated schematic and panel layout can be found on my website.

Best Regards
Laurie Biddulph
