I poked around USR a bit when I worked for 3com (ie after the 'merger')
and got no progress.

Amusing side exercise. List the patent licenses required for a 33.6
modem remebering in the US the USPO has some odd ideas about patenting
pure maths.

You claim the CPU difference is $6. Ok where are the numbers from. Digitals
own figures for a 200Mhz strongarm SA110 and their commercial software
mode is 25% of the resources of the chip. The real issue though appears
to be entirely patents and chip documentation.

Way off. Firstly Im dubious about the 8Mhz, secondly the R4K's tend to
have DSP instructions (ones that are useful). Pentiums dont have an
add/multiply with no stall instruction once per clock.
