<sigh>  but why would the obp say ss20?  iirc ss20 firmware doesn't
work in a ss10, except for the ross 2.25R which was specifically coded
to handle both.

you could try chipping it to 100MHz...  it's been done to vanilla
ss10s, but i don't know if and/or how long they're reliable.  perhaps
replace the 66/72 MHz osc, so you could jumper it back to 80 if it was
