You got something against Artie's (RT's) three letter commands? :-) And they say Unix is cryptic. Sheesh. > Someone suggested I upgrade it to an 11/73 and possibly run bsd's > public domain version (2.1 I think).

This will cost you a bundle as you have an 18 bit backplane and the 73 is a 22 bit backplane. If you had a 23 Plus it would be more reasonable. Only the cost of the board swap. The 73 is a better machine though. Maybe cost you $2,500, US just for a used processor board, KDJ11-BB in Digital Basics. Now add $4,200 for a meg of memory... Hope you like segmented architecture, cause thats all ya get. A whole box maybe $5-$6K. Oh, you want a disk.... > I would prefer to run Unix on the system as is if possible. Good choice. > Is it worth the time and effort to investigate these questions? Probably not as they suck power like there's no tomorrow. You could pick up a nice 386 with scads of memory and disk for the same price with a CPU thats three times as fast with virtual memory. No contest. > Thanks, De nada.
