Jim you mean the P/390? I have a couple of those yes. First ones were
Microchannel; later ones were PCI. S/390 CPU & memory on a card; all
other devices emulated under OS/2 or AIX. Could only run the earlier
versions of z/OS; they were strictly 31-bit only.

For one person, in the dark, where no one will ever know or see.'
