Try to sell the whole system on comp.os.vms
http://groups.google.com/group/comp.os.vms/topicssome people may interested for it!
NT 4.0 was the last version that supported ALPHA, (the NT 4.0 CD, has the Alpha version too)
There is also one 'beta' version of windows 2000 that runs on Alpha (but is... beta ;-} )
You could run Tru64 there, but the ****** HP does not offer a hobbyist license anymore :-(
