[erlang-questions] Erlang on VAX

[Gordon Guthrie]

That memory seems very large for 1980!

When I was on the Cray-1X at ULU in ’86 it was *alleged* to be the only machine in the UK with a Mb of RAM…

Mere programming peons like me didn’t actually see the computers in those days so anecdote is all I have :-(
