UNIX OS needed for IBM PS/2 Model 70

[Gail Wauford]

I would greatly appreciate any information based on first-hand
experience on UNIX operating systems (other than AIX) for the IBM PS/2
including brand name, supplier, cost, hardware requirements, etc.

Also, if anyone has used the UNIX operating system developed by
Interactive Systems with a PS/2, do you have any comments pro or con?

Thanks,
Gail
