RE: Wico XY Pattern Generator - Decoding Switches

John,

I already have mine apart on my desk. I'm looking at it now. I'm taking lots
of pictures.

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.

I have a working WICO XY Pattern Generator if you need any pictures (either
of you) just let me know and I'll crack it open...

You can mirror the schematics from ionpool

I'm looking at the schematics for the Wico XY Pattern Generator; and can
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?

John

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.
