| The 34010 is actually the TI graphics chip.  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

| 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.

Anyone know?
