Well, I haven't been speculating about who actually built any of these,
but I have a gen-u-ine application note from Motorola describing the
scheme.  It's sitting under my engineering sample MC68000L8 (T6E mask).

68K Trivia question #2: T6E was the last pre-production mask set--what was
the difference between it and the final production mask (in operational
terms--I'm not looking for a description of chip geometry :-))?

All this reminiscing... the thing is, it wasn't all that long ago...
