Yup, or whatever. You need to connect to a unix machine with an
internet connection. On that machine you run a perl proxy that
translates HTML and images to something that HyperLink understands
(linkscript iirc).

But expansion memory isn't always suitable -- it's not directly
addressable, and slow to work with. Paging in a 256-byte buffer from a
REU costs almost 300 cycles, and a single IP packet can be much larger
than that.

RB> The main question is: is a C= _fast_ enough?

Barely. Take a look at LUnix, it has a working TCP/IP stack and
doesn't need an accelerator. For simple text-based protocols such as
SMTP/POP or irc, it does work.
