VMware Documentation for SCO OpenServer 5.0
The document does give a variety of helpful information regarding getting SCO guests to work. Interestingly, it also says:
VMware Tools in an SCO OpenServer 5.0 Guest
VMware does not support the port of VMware Tools provided by UnXis in the SCO OpenServer 5.0.7V product..
Who is UnXis? Xinuos - Wikipedia reveals that it is a former name of the current owner of the SCO operating systems.

In particular, note the "The SCO OpenServer 5.0.7V Virtual Appliance" section, where it indicates:
SCO OpenServer 5.0.7V Version 1.0.0 for VMware is delivered pre-installed with the following major components:
- SCO OpenServer Release 5.0.7 Enterprise Edition
- SCO OpenServer Release 5.0.7 Maintenance Pack 5
- SCO OpenServer Release 5.0.7V Virtualization Extensions
- vmtools - VMware Tools
I had already learned that "SCO OpenServer 5.0.7V" is a virtualized edition of the operating system. With that in hand, I found this:
