It is my understanding that that V.32 requires much more in the way of
computational hardware than the Trailblazer Plus has to offer (I
believe the Fujitsu V.32 modem has 5 DSP chips).  This being the case,
I would have to assume that the upgrade consists of a new modem board.

Also, implimenting FAX on a 68000 would be pretty slow, especially if
you were trying to do Group 4, 2D.  Most implimentation of FAX that I
have played with were custom logic or special purpose chips such as
the AMD 7970A/7971 or TI34010 w/ FAX library.

If I am mistaken, please correct me, but the only way I see to get
these features is new hardware.  Thus, an $800 charge is not so
unreasonable.
