My friend who has both versions only remembered seeing
a version
of the Host version of the cards and cables for the Micro Channel
version, and not for the PCI. Univac supported the host version on
the PCI card set.
I have the PCI version, so I know it exists, but yes, the MCA version
was a lot more common.
IBM systems with P/390's were more likely to be in
Escon farms than
in bus / tag. The R/390's may have been more likely to be in sites with
SSA available, which IBM was pushing at the time the P/390's were
in vogue. Therefore less likely to see Escon versions of that hardware
or the Bus/Tag versions.
If memory serves, the ARTIC960-based ESCON adapter still goes for $big.
They're popular for adding ESCON channels above capacity in the
MP/3000, in shops that can't afford to trade in their MP/3000's for
z800's or z890's.
