<DECNET is fine, if the machine's you're putting together support it nicely <Don't discount the effort it takes to get a PDP-11 properly configured and <the peripherals running - sometimes I'm sure you'll get lucky and it'll <just work when you plug it in, but when stuff is coming in "unknown" or <"not used for many years" condition, it can take time to get everything <going happily. An aside, in the PDP-11 realm the Qbus 11s like the 11/23 series are by far the easiest to get configured and going. the Unibus machines require a much higher load of knowledge of small bits like what bus level jumpers must be where and all. The beauty if that a 11/73 series will run most PDP-11 unix and PUPS has the license for any version at $100 and also an archive of PDP-11 versions of unix. <versions from the early-mid-80's onward. (i.e. RSTS/E V7 and on, RT-11 V4 <and forward with some earlier V3 And V2 distributions, RSX-11M 3.0 forward <and RSX-11M+ V2.0 and forward, with many of the layered product kits <thrown in for good measure.) I do have RT-11 V3 and V4 on TU58 still. I should dig them out and see if they can still be read (I have three solid TU58s). Allison
