    Lets see, the big differences are one, ethernet, which you mentioned. I
think the 125 also uses a C-LANCE chip as opposed to LANCE in the 200. The
200 has a 25MHz TurboChannel bus, where as the 125 has 12.5 MHz. The 125 has
Zilog serial chips and the 200 has DZ based serial chips. The 125 has CPU
daughtercards that can be swapped, the 200 does not, its stuck at 25MHz
R3000. The 2x0 series can hold up to 480MB of RAM, which is full parity
interleaved modules. Beyond that, the 125 has newer chip technology which as
far as I can tell runs as a whole about 20-40 degrees F cooler than my 200.
You could boil water over the MMU on my system. I'd hate to think what would
happen if the cooling fans crapped out :) Maybe its just my system, I dunno.

    I have a pinout if you want to make your own. Get back to me and I'll
see if I can dig it up.
