1 connection 4 addresses on 3274 according to the data sheet. So three LPARs plus VTAM screen would be possible. Lloyd

So now I'm wondering how consoles from 3 different LPARs appeared on the same screen, plus a spare with a VTAM welcome message. At the time I thought all our consoles were direct connections (defined as unit addresses). It was a long time ago so this could have been a dream or nightmare.
