If it's a 40 pin chip then you might br able to do
it by a process of elimination!
The 5 40 pin chips in a Dragon or CoCo are 6809E,
6883, 6847, 2 off 6821.
Good point.
But, I need to know which chip goes in which
position...
Using your idea, it looks like the two missing chips
are the 6809 and the 6883 (which would make sense, as
Bob sold those as spare parts).
But, I don't think it would be a good idea to put the
wrong one in the wrong place, and I still need a set
of ROMS.
