Sampsa, I acquired an AS/400 box a few years ago. It is about the size of half a "standard" refrigerator and was at least a two-man lift (fortunately, I was able to roll it). I've been trying to obtain a demo copy of the OS with no luck. I'm fairly certain one may be better off trying to emulate the hardware (I was able to do this with either OS/390 or Z on a mainframe emulator several years ago). Still no luck in the AS/400 space ...

How much do these things cost (like say a 93 vintage), weigh and dissipate heat? Also, how do you hook them up? Sampsa
