I'm assuming you did (Danger Will Robinson!)... were compliant boards reliable? Do you know of any attempts to retrofit compliance onto existing S-100 designs? -dq

I think your sister has the right answer.

Well, much as I dislike Outlook (depressed or otherwise), it actually is capable of sending plain text. You just need to make sure it's set to generate plain text (not HTML, RTF, or multipart/mixed) in some reasonable character set, for new messages, AND override the use of HTML/RTF/whatnot when replying. Besides, there are plenty of other Windows mailers besides Outlook; it's not a reason to go off the deep end. > However, you need to remember that not everyone here uses that Microsoft > rubbish, so you shouldn't be sending e-mail that requires the recipient > to do anything other than read it. True, in fact the Merrill Lynch survey I saw on CNN a little earlier today showed that less than three-quarters of people using Windows use Microsoft email software. Since only about 2/3 of PCs (in the loosest sense) run Windows, that means only about half use Outlook etc. -- Pete Peter Turnbull Dept. of Computer Science University of York

Tapes

Does anyone know where I can locate blank computer cassette tapes for the Commodore, etc.? Music tapes are usually too long. From: "Stephanie Ring" sring(a)uslink.net

But you ought to realise that ISO-8859-x is not ASCII; the lower 128 characters are the same but the remaining 128 (top bit set) are foreign-language characters and additional symbols -- ASCII is a 7-bit character code while the ISO 8859 ones are all 8-bit. -- Pete Peter Turnbull Dept. of Computer Science University of York

Together, democracy and free enterprise constituted a severe paradigm shift for the robber barons, but eventually, they figured it out. So, if they're going to stand behind every tree on the highway, ready to exact from us a toll for any thing we want to do, then we have to figure out how to travel without using that highway, rendering their strong-arm tactics moot. -doug q

All this talk about RT-11, RSX-11M,RSTS/E licensing details is making me wonder. If I acquired a PDP-11 of some kind, and it came with RSX-11M and/or RT-11 and or/ RSTS/E, would I have to have a license? I know a license is legally required, but is it essential in running the OS? Does the OS have any way of checking for one? What is required for running the OS? I really don't know anything about the PDP-11 family. Thanks, Owen

Ah, I stand corrected... and that would explain why the system was always flaky with that board in, and stable without it (I was blaming the bus). So, knowing nothing about the half-life of the welding material, can you tell me, has the material in the welds decayed enough now that the board should operate in a more stable fashion? -dq
