Hah! We are talking about an IBM board here!! :-) There was some
kind of ROM on the board, it may be an 8051 with EPROM? Or possibly

Speaking of DSP the new AT&T 3700 modem (from paradyne actually) has
a DSP and it seems to be driven by an easily modifyable rom. Just another
While we are blue skying about this - what about the idea of using two
cellular connections in parallel? Aside from cost it might create some
interesting interception problems.
I'd like a 250 Mhz 128 bit hybrid processor with 64 meg of 8 way interleaved
