Classic bad-video american with sparkles
Classic bad-video american without sparkles
  (these MIGHT be the same board, with different ICs)
newer breadbox board (8pin video port this time)
Newest breadbox board (with 7701/8701 clock generator)
Another 7701 clock gen board, but with two 4-bit-wide drams instead of 8

These are the breadboxes I've worked with.

C64c with 2114 static ram, and (I've never see this, but its verified to
exist) a second c64c with the static ram in the PLA(mmu).
