I don't think it was on the 9th floor, at least
not when I was hanging out there.
It was on the 9'th floor. There where "footsteps" glued to the floor,
"the way to OZ".
Rob Austin was sys$manager, and it was used to develop "Chives" the domain
resolver,
but it belonged to the folks on 4:th floor not 7:th floor.
The 2020's showed up much later and was only used to run ITS.

Subject: Re: [HECnet] Is this the most up to date version of DECnet OS numbers?
I was in touch with Lars recently, talking with him
about putting 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.
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 maybe
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.
I'm not sure if the IBMSPL software had extensive
usage. Earlier versions of it
were very 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.
In addition to routing CCnet (DECnet) email to the
ARPAnet, we also routed the
entirety 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.
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)
