Bob,
I forgot to ask... do you have stock in your local electric company? The BA123 is 645
watts! I know I have one with that I can run multiple boards (microVAX-II, microVAX-III,
PDP-11/23+, PDP-11/83, PDP-11/93). I use it to manage physical drives (RD5x) that I can
clone using NetBSD to virtual drives for SimH (and vise versa). NFS is a WONDERFUL
thing! :-)
I can also help with RSTS/E version 10.1L (last version) and a multitude of languages.
Set host to PLUTO:: and take a look around.
Send me mail off list for access...

?Bob,
With two drives why not put both operating systems on. One on each that way you get to
play until YOU decide which you like better!
