I think I have you covered. I have an unopened Vector Graphics RAM/ROM
Revision 3 board with full assembly guide/user manual/schematics. Includes
source for a memory test program, the Vector 1 Monitor 1.2 source listing
and an errata sheet with an extra jumper.
Here's a pic of my board/parts:
Oddly enough, my Vector Graphics 1++ has the 12k RAM/ROM board so I don't
have a Rev 3 running. I'll scan the manual tomorrow and email you a PDF.
Hope this helps.
