It's good to hear that the VAX was a cost-effective solution - there are too many stories about how expensive DEC gear was, but I imagine they primarily came after PCs started dropping in price. On 9 February 2016 at 04:50, Ethan Dicks wrote: > On Mon, Feb 8, 2016 at

My memories from the early 1980s are of a room full of undergrads working on rows of VT100s (maybe 50+ at least?) on a DECSYSTEM-2065 running TOPS-20. Things usually seemed to run pretty well on that system, until the night before programming assignments were due. Nothing quite like a room full

Just thinking about Mark’s email here. Keeping in mind that this is from a DEC persons point of view. You probably all know and appreciate this. While the DEC hardware may have been more expensive than other companies many customers are still running the hardware today. I am thinking of
