PCMCIA is capable of the speed, as long as the pcmcia serial card is
capable of the speed, then I'd imagine it should be fine....
(I have not done this myself, although I do have SBUS PCMCIA adapters
and recently aquired an ethernet/serial PCMCIA card that came out of an
old EMC RAID array control laptop ... don't know if any of the Sparc
BSDs or Linux distros support it though... haven't looked into it yet)

The easiest way might be to use an SBUS PCMCIA adapter and a PCMCIA 56K

Can't say... I've never done it myself, but someone else here claims to 
have done it.... hopefully they can reply with some more specific info
regarding how well it works.

yup... and the adapters are getting cheaper and cheaper to get on ebay.
