I'm referring to the microchannel P/370 (POS Id. 8FC4, aka "IBM
Personal/370 Adapter/A").  The P/370 did not come in ISA or PCI.  It ran
VM/SP, VM/ESA 370 Feature, and VSE/ESA in 370 mode.  No 2K storage key
support so MVS 3.8 was out.  The same board ran (with appropriate
software) under both OS/2 and AIX v3.

The microchannel P/390 was the predecessor of the PCI P/390, not the other
way around.  The R/390 (RS/6000) was the microchannel P/390 sold with a
different software package.

I still have a fullpage P/370 ad on my wall.  Neat looking board.
