R: Wico XY Pattern Generator - Decoding Switches

I was building my pattern generator from those schematics but I never
finished the project

  John,

  Before you mirror the schematics let me take a look at them in depth. It
was a looooooong time ago when I drew them.

  Unfortunately, I no longer have the schematic source file or access to
PADS schematic cap even if I did. I looked at them online and yes, something
looks screwy about the switch board to main board connector pinout. I'm
thinking there's a reversed connector involved here. I'll let everyone know
what I find.

  You can mirror the schematics from ionpool

seem to figure out how the Front panel PCB connects to the Main Board.

  At A-8 on the main schematics page; it shows P3-1-8 as connected to the D
Flip Flops and the A10 of the U7/U8 pattern generating roms.

  However, P3 doesn't seem to connect correctly to the "cable" connected to
the front panel board at B-8 on the second page.

  It appears that the diode matrix appears to drive set/clear to Dflip flop
U6-A which controls A9 on the ROMs.

  But I'm unsure of the encoding given I can figure out how "P3" connects to
the Front panel board.

  Anyone have an idea?

  Do you have a copy of the schematics so I can put them up on TTL? The
manual (such as it is) is there along with images of the Eproms.
