Connect to ssh-1 server from recent Ubuntu

[Liam Proven]

Google and Duckduckgo are both drawing blanks. Nothing even related.

A chap on a vintage-computing list wants to connect to a SunOS machine
(pre-Solaris) with SSH from "recent Ubuntu".

SunOS that old only understands ssh v1. He says that seems not to have
been available since Ubuntu 10.04.

Is that right? You can't specify older versions of the protocol?
