Olivetti ran a bunch of machines, you can find them in old USENet maps as "olive[a-z]" and some of those ran Amdahl UTS, and I used one of those for SVR4 work at Ivrea around 1989. I have no idea what the actual hardware was, but it was the first time I ever had to pipe df(1) into more(1) :-) -- = Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk@FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe = Never attribute to malice what can adequately be explained by incompetence= .
