I thought maybe the z/800 machine is not so "smart".
I will check again code, I think I made somewhere a mistake.
It is a long running STC server, and I have compared the "startup" CPU

As far as I remember , I don't made any significant  change.
The conversion was quite "mechanic" .
With  ARCHLEVEL=2 most of the system macros compiled well with baseless
