If you want to replicate the old-school Unix experience, you'd need it to take more like 15 hours to compile all the tools :)

My DEC Rainbow running Venix (v7 port) takes about 15 hours to build the bits of the v7 tree that build on it. I don't have the sources to Venix, but a long-term project is to recreate them using the compiler supplied and comparison to the binaries shipped...
