As Anthony says it is very very old, but I might be fun if you had the time on your hands. The 2nd edition books/cdrom are nolonger available but you might find a set seccond hand (abebooks.com etc).
The floppys are here: /n/sources/contrib/steve/historic/2nd-edition/pcdist/ I found a complete mirror of the old 2nd edition site and I think uriel has copied it to cat-v.org. You will need 16Mb to install and 8Mb to run a terminal though It will work at 640x480x1 resolution. The 4th edition should run on a 486, though you will need (say) 128Mb of ram - much more if you want to recompile gs(1). -Steve
