You can replace the SS1 motherboard with a SS1+ or SS2 motherboard and it
will work fine (just faster!). The only difference to watch out for is that
the SS2 boards run quite a bit hotter. Genuine SS2 cases are very similar to
the original SS1/1+ case except they have a little more room inside and have
an extra fan. The CPU boards are exactly the same size and shape though.

If you get an SS2 board, you can replace the CPU with one of the Weitek
PowerUP chips to increase the performance further again (about twice that of
a standard SS2, which is about 4 times that of a standard SS1).

The other avenue is to buy a Sparc-5 clone board from a company like Cycle
Computer (http://www.cyclecc.com). They make Sparc-5 clone boards that fit
in SS1/1+/2 cases, although they're expensive compared to surplus SS2 boards
with or without the Weitek CPU upgrade.

Regards,

Craig.
