I asked one of the old IBMers at work what this powerstation 550e i had was.
turns out it is indeed part of the RISC6000 family. I guess what i have is
just a workstation that ran batch jobs or something like that, not too useful
by itself it seems. I presume it runs/ran AIX. it was difficult to find any
info it. web search didnt bring up anything, and 800-IBM-SERV handles the
RISC6K family, but they referred me elsewhere for this 550e, since they didnt
know what it was. it only cost $5, and it is an interesting addtion to my
ever growing esoteric collection of ibm machines. now, if i could just get
this powerstation to run with my PC RT...
