I have the same kind of issue as your's, just not that bad. As my P133 is on a Epox MVP3-C board.
Anyway.... I have these kind of sollutions for you.
Do you own something like an ATX SS7 board, wich are not in use as of right now?
In that case, try to install the P-233-MMX on to that board. (Boards like GA-5AX, PA-2013 or P5A)
My Epox is actually some SS7 board in AT-Form factor. (besides not being able to take full size ISA)
The good part of takikng this approach, is that you will get some more recent technology using ATX.
And you will have more luck in finding good PSU's, when it comes to ATX versus AT technology.
And you will have more luck in finding a board, that can take full size expansion cards.
I know this is not true to the Pentium-1 years. So it will not be a true P1-MMX system.
Yet some times, you have to give up hunting for something, unless you have access to a lot of parts.
Don't eat stuff off a 15 year old never cleaned cpu cooler.
Those cakes make you sick....
