Compatibility of uport and sco with IBM PS/2 model 50Z

[Ray Curci]

I have an IBM PS/2 model 50Z and would like to run some form of UNIX.
The 50Z is similar to a model 50 except that is has faster memory
access and a different hard disk controller (I am told).  I have sent off
and received literature from uport and sco.  In the Q/A section of the
SEP/OCT 1988 DISCOVER newsletter from Santa Cruz Operation it says that
SCO Xenix release 2.2.2 is not compatible due to the new hard disk
controller, but a fix is available from SCO "PS/2 Model 50Z ESDI Fix"
(SLF xnx100).  The article also says that the standard release 2.3 
distribution will work.  

I have spoken to the people at Microport, but have only been able to 
reach non-technical sales people who don't understand the question.  
I can only get the response "Well, since our product is ps/2 model 50
compatible, it should have no problem working with the ps/2 model 80.

Is anyone on the net using a real ps/2 model 50Z with either  Microport
or SCO Xenix?  If so, what version of the o/s are you using?  Have you
noticed any problems with this configuration?   I have had some bad 
personal experiences with the 286 version of microport  v1.3.6 about
a year ago, and don't want to have another bad experience.

Thank you for your time,
