True for the upgrade to 56k, but firmware in Zoom V34s can be
upgraded to V34Plus - there are also updates.  Both are contained in
a hardcoded firmware ROM chip.  Lever out the old and plug in the new
These upgrades can be purchased (US $10 +$10 s&h)
Updates are sent out free.  56k models are available
on a trade-in deal, dependent on when bought (US $79)
The details are on their WWW site.  56k models are FlashROM updateable

It's not the processor on a 286 but its UART chip which can't handle
a fast modem's data speed.  They usually contain an 8250.  Internal
modems carry their own UART which should be alright.  Mind you my
experience of slower computers goes back only to a old 386/16 (with
MFM harddrive, remember when 80meg was max and these were considered
the bee's knees? :)
