Chaosnet back into the PANDA distribution as a number of programs
(such as the mailer and FTP) know how to use it. I also wanted to
put the VTS (SUPDUP) service back in, too.<br>
</p>
<p>I've spent some looking at the code and I believe there were two
different Tops-20 implementations, one for the KL which ran on XX
and EECS and <i>maybe</i> another that ran on the 2020. ITS uses
that hardware configuration. I don't remember anything about OZ,
I don't think it was on the 9th floor, at least not when I was
hanging out there.</p>
<p>I'm not sure if the IBMSPL software had extensive usage. Earlier
versions of it were <i>very</i> cantankerous, but it improved. I
knew one of the authors at Marlboro (K. Reti) who I thought was
one of the more brightest bulbs I had come across. Columbia used
IBMSPL extensively, but not for the reasons you'd think.</p>
<p>In addition to routing CCnet (DECnet) email to the ARPAnet, we
also routed the <u>entirety</u> of BITnet, which was a 'network'
of IBM mainframes that sent email to each other. It wasn't SNA,
they all looked like RJE workstations and 'punched' card decks of
email to each other. I think our news feed may have come through
IBMSPL too.</p>
<p>In other words, that particular software was beat on day and
night and eventually functioned quite competently. I keep
thinking about putting that up, too, although I don't know how I'd
get the PDP-11 code working (or what it might talk to)<br>
