[TUHS] Do you have any historical UNIX computers?

[Henry Bent]

Sorry, I sent a response only to Warner by accident.  SunOS 4 runs just
fine on MP machines, I have a dual processor HyperSPARC SS10 running right
now.  The MP support isn't ideal by modern standards but for the time
period it's fine, and it definitely works well.
