Interestingly, it is also a pretty sharp 5MIPS or so general purpose processor. They have a CCITT Group 3 & 4 (aka fax) image compression package that runs as fast as the dedicated AMD fax compression chips. I never thought of it as a modem chip, but it makes a kind of sense... > >It woulda been kinda neat to have a software trailblazer :-) I don't see why its not possible. My understanding (sure to be flawed) is that the PEP protocol used by the Trailblaser is a software only protocol. It should not be difficult to code a 56001 version of PEP, if this is true. >-- ><-- David Herron; an MMDF guy ken seefried iii ...!{akgua, allegra, amd, harpo, hplabs, ken@gatech.edu masscomp, rlgvax, sb1, uf-cgrl, unmvax, ccastks@gitvm1.bitnet ut-ngp, ut-sally}!gatech!ken
