They did indeed. Which brings us to why these were stopgaps at best:
The processing may have been faster, but the memory/bus interface was
the same, so you were not truly getting the overall performance of the
real machine (that's why the advertised benchmarks were careful to
demonstrate how much faster the upgraded machine was compared to how it
was before, and NOT to a "real" 386).

You might run into an issue of minimum clock
speed
too. I don't know what
the minimum for the 386/486 is. I know RISC
microcontrollers can go down to
DC, but the 8386/486 might not.
Presumably the boards these things come with have
their own crystals. I would not expect a '486 upgrade
for a '286 to run at 8mhz or anything comparable (but
Tony could tell us).
