- You don't have to shout, we can hear you.
-
- If the question can be extended from computers to terminals, then there
- are people with data. At SoftQuad a few years ago, almost everyone had
- an HDS200 terminal on their desk. We had a continuing problem with
- power-supply failures. It was conjectured that turning the terminals
- off overnight was the proximate cause. We ran an experiment -- half
- the company turned them off overnight and the other half didn't. The
- power-supply failures then confined themselves to the first group.
-
- Of course, this doesn't prove anything about equipment in general --
- it only shows a problem in the HDS200's power supply. (This came up
- in comp.terminals recently, and certain Wyse models were mentioned
- there as having the same problem.)

- I can't resist telling again about the most strongly burned-in image
- that I ever saw on a screen. I saw it in 1982 when I was visiting the
- company in Ann Arbor, Michigan, which at the time was BNR Inc., owned
- by Bell-Northern Research Ltd. of Canada, which was my employer at the
- time. The Ann Arbor branch had previously been a small computer
- manufacturer called Sycor. On the premises was an area where a bunch
- of old computers and/or terminals were stored. And on one of them was
- the following burn-in, as legible as if the terminal was still in use:

- Who says they don't? Haven't you ever heard reports from people whose
- wires took a serious surge? The thing is that the computer could easily
- cost more than all those other items put together, so maybe you care more
- about protecting it.
