PowerBook 540c, PowerPC upgraded — can downgrade?

I am not sure if the original poster got a 68CL040 chip or not, but if not, I think I have one that may work, if you want.

I had both a 520c and 540c that worked, but I canabalized the 520c case to make the 540c cosmetically better.  I have the 520c motherboard, processor, and Ram (the RAM and processor are still attached to the motherboard).  It is listed, however as 50/25 mhz, so I assume it is slower than the 540c's stock 33mhz processor.  Would such a thing even work if plugged into a 540c board?

This brought to mind movie I just noticed macs in.  Gremlins 2 the secretary has a mac Plus all up and running and next to it with no monitor is a Mac II series with no other parts, no keyboard , no mouse , no monitor.

Gods I love that movie.  Not too many movies make fun of themselves.  If you think it's funny now, watch it with Cast & Crew commentary.  They point out so many hidden jokes.  One of my favorites is a U-Haul Moving and Storage... on the second floor. :lol:
