My friend Eric, had an unused Alpha server 4100 under his desk...It was used for testing more than a year ago, ( in the early 2000s ). He asked for the install disks, and got a entire box of everything it came with VMS/Ultrix/NT 3.5.. We tried to use raid, but none of the drivers worked. So what... we loaded NT, then Digital UNIX, and finally VMS, but we knew nothing about VMS, so one disk for NT, and one for Digital UNIX. The floating point was outstanding. just wish there was more software for it.
