The upgrade price is $395 for modems built after some point in time (1/1/89?) It is $795 for modems built before then. The difference is that the modems built afterward have some magic thing on their motherboards which makes it easier/cheaper to do. For the older ones the upgrade is a complete motherboard swap. Note that the difference between a TB+ and a T2500 is much more than just a ROM change. Telebit doesn't do V.32 out of the DSP chip they do PEP in. This is because the DSP chip they use doesn't have the CPU bandwidth to do V.32. Instead they add in some off-the-shelf V.32 chips, and do the rest with DSP+ROM as is done in TB+'s. My modem was built before the cutoff :-( -- <- David Herron, an MMDF weenie, <- Formerly: David Herron -- NonResident E-Mail Hack <- <- Sign me up for one "I survived Jaka's Story" T-shirt!
