Al 23/12/12 23:21, En/na Cory Smelosky ha escrit: i'm not getting anywhere with my TOPS-10 endeavours, I thought i'd try something else: older VAXVMS in SIMH's VAX-11/780 simulator.;) 1). What would be the best/most interesting version to try? 2). Where would I get install media for these older versions You could try to build a VMS 4.7 system. To do that you will have to build a 4.6 and then upgrade it (IIRC 4.6 has also a mandatory update to apply). Previous to do that you will need to make a stand alone backup bootable kit. I made a bootable tape image using a running openVMS 7.3 system so I was able to boot STANDALONE BACKUP in the 780. Alfter that you can restore then 4.6 tape and boot it to install the rest of 4.6 and later upgrade to 4.7. You will find 4.7 in the 780 simulator boots really fast ;) The kits and some layered products are available at ftp.trailing-edge.com. Good luck!
