We have both a consulting and a software side, on the consulting side the 
oldest machines we have are:

4 z/800's running os/390 2.10, z/os 1.4, 1.7 and 1.13
2 9672's both running OS/390
1 4381 running MVS/XA 

All of these are production systems, and for some very special reasons they are 
at the hardware level specified.  

In the past 2 years I personally have converted 8 sites from 3 9672's and 5 
z/800's to z/114 or newer boxes running z/OS V2.1.  All of them were straight 
jumps to z/OS 2.1 and they were all completely successful.  The oldest jump was 
OS/390 2.7 to z/OS 2.1.
