just wondering where on earth you'd find an RL02 in 1974.

Western Dynex had 2.5mb removable over 2.5mb in 71.

Last version at link above, model 6000 is essentially an RL02. Came in
12, 18 and 24 sector (strapable). I think it could be hooked up to DEC
as the interface was pretty much the same.
thanks

All this talk about compatibility...was there
ever UNIX made for the PDP

this an issue now? I am
largely ignorant to the details but from 20000 feet it would seem like
