You are probably going to have problems with that.  It has been pointed
out that the software needs tens of kilobytes, and there won't be much
memory left for storing the page being displayed.

I've been looking at Pasi Ojala's PuCrunch, since a couple of local guys
suggested an idea of making an all-games-in-one cartridge for the VIC-20.
The most feasible way is to compress all games into a 1-megabyte image,
and to write a decompressor that extracts a game from the huge ROM to a
32k RAM on the cartridge.  Using a 700 MHz Pentium III, the compression
task takes a bit under 30 seconds (I tried it yesterday).  What I'm trying
to say is that instead of trying to do everything on the C= side, it's
much easier to combine the two worlds.

Forget it.  ISDN is unnecessarily complicated.  The communication protocol
DSS1 is kind of parallel to TCP/IP.  All you need to implement TCP/IP is a
data path, and getting that is simplest with normal modems.

It depends on the card.  The easiest way to find out is to investigate the
source code of the ISDN drivers supported by Linux.
