What would be the best/most interesting version to try? 2). Where would I get install media for these older versions? ;) I have a bunch of older VMS distributions. I don't know if they're available anywhere else or not; I would assume so but am not sure. At least several 3.x and 4.x distributions, going back to 3.0. Let me know if they're wanted and I can put them up somewhere. Please upload them, I am quite interested in older VMS. I'd say 4.7 for speed and period-correctness, 5.5 for feature fulness. Maybe i'll go with both! The last release of VMS to run on an 11/780 was, I believe, v6.2. I have a copy of 6.2 in some file format nothing knows. VMS doesn't even seem to. -Dave -- Dave McGuire, AK4HZ New Kensington, PA
