I bought one of the B-Land cubes. We're talking OLD. Serial # is around
1108 or so. Anyway, I got my 040 and swapped the Simms (8, old 1MB,120ns 
and 4, new, 4MB 80ns) and I've had no problems.

I THINK that the speed rating of the chip is only representative of what
its 'batch' was tested for. There are no real differences in the actual
fabrication process. I had 120ns chips in a MacIIci which wants 80ns for
over a year with no problems.


Basically, if it works then I'd use it.
