I don't have this - can I get the same info off the 'net, or do I have to
go fiddling about with fax-back systems to get it? I think also it might
be a Motorola chip rather than a Rockwell one. Does anyone have a URL
into Motorola.com that can find datasheets. I did get there once, but
that was from a link from a massive chips database, which I can't find
anymore (I should have bookmarked it, I found it doing a net search for
6522 or 148616 or some such).

I'm not quite sure what you mean here (I'm no expert). Care to expand on
that? :)

Well - it seems to have support for native drivers, BUT there don't seem to
be any :(

Or even better, using Econet-over-ether, emulators running on different
machines on a network talking to each other :)
