Disinterested parties should exercise the "delete" button. This is from one of Jerry Pournelle's many articles in BYTE magazine almost thirty years ago, about a Sage II computer, a rather nice 68K-based machine that ran either CP/M-68K or the UCSD P-System. I have one of these systems in my (budding) museum. -Dave "When I visited Sage at the Reno headquarters,...I also saw the oddest computer I’ve ever seen in my life. I mean. I’ve seen plenty of desktop computers, but I never saw one bolted to the side of a desk before; yet there was a perfectly good Sage II in that situation. It was running, too. None of the Sage crew seemed to think that was odd at all. They were used to it. Finally, I had to ask. It turns out that in the early days of Sage, when they first began to ship machines, they got more orders than they could fill; so that whenever Bob Needham, one of the cofounders (with Rod Coleman), would get a machine to help him with advanced system design, someone would see it and ship it off to a paying customer. Eventually Bob decided that enough was enough and bolted a new Sage II, sans case and fan. onto the side of his desk. The disk drives and power supply were in a drawer." -- Dave McGuire, AK4HZ New Kensington, PA
