Hmmm... there aren't slots for 3 CPU boards and one memory board?
A friend has a Challenge L I thought about trying to max out, and I was
counting on being able to do 3 CPU and 1 memory board. I could have
sworn when I looked in there it had room.
If not, oh well... hard to complain for free.

Yeah, which is really too bad. Both are nice.
I want the graphics and more bus slots. By the time I ever find what I
want, I won't be able to remember why I wanted it.
