That's one of those legends that only a few Elite warriors were able to see with their own eyes ;-) A board with no ASSY#, called "KU" after the "KU-xxxx" silk-screened mark

So far I believe we have:

- "5 pin" board (326298) three ROMs B-K-C, raster 1.0"(?)
- "KU" board three ROMs B-K-C, raster 1.0" (?)
- remaining "wide" boards three ROMs B-K-C, raster 0.8"
- "narrow" boards two ROMs C-BK, raster 0.8"
- SX-64 CPU board three ROMs C-K-B, raster 0.9"
