Boot software for a 3Com CS/2600 Terminal Server.

Hello all!

I was wondering if anybody could help me.  I have recently acquired a c.1994
vintage 3Com CS/2600 Terminal Server.  Unfortunately it has been supplied
without software, either on 3.5" for the internal drive, or as a TFTP boot
image.  Extensive googling hasn't helped, and 3Com aren't able to help me
either.

I was wondering if anyone in the group had such a rare piece of software,
maybe lurking in the /tftpboot of an old machine?  I believe the software
for the CS/2500 and CS/3000 is compatible, and the last released version was
"CommServer TCP 6.2.1" but I'd be grateful of any version at all!

Thank you in advance of any responses.

Kind regards,
Austin Pass.
