Over the past 15 years, I probably have accumulated over 100,000 e-mails and posts in about 130 folders!

However, under Netscape 7.2, I am able to CLEAN CACHE and that did seem to restore everything back to before I accessed the links. At the very least, all of the files that were placed into the \cache\ sub-driectory were removed and the total number of files and sub-directories reduced to the original value from before the links were accessed. I don't know if making sure that there are no extra files and sub- directories around after I use Netscape 7.2 to download my e-mail, but I use that criteria to determine if anything that should not be present has been added to the C: drive. I realize that pre-existing files could have been corrupted, but I can't monitor everything. Also, after I download the incoming e-mails, I physically disconnect the cable to the router so that any e-mails with links that could be activated to files that might cause a problem can't be completed without the internet being available. If anyone who has read this far has any comments or suggestions, they would be very much appreciated! > Under WinXP, I looked over your page on emulators.

>Johnny Billquist bqt at update.uu.se wrote: >some of the 8000-series stuff are probably the biggest ... Not all of them. The 82xx/83xx family was just one 10-1/2" chassis for the CPU - the same physical size as a 11/730, yet they were genuine single or dual CPU BI bus VAXen. Of course, many of their brothers were quite a bit bigger. And don't forget the VAXstation-8000... Bob

cctech Digest, Vol 13, Issue 5

The primary processor is called the "executor" and the second ?is called the "fixer." The fixer is either halted or runs a small loop keeping the translation buffer (TB) full. When the TB logic detects a fault for the executor, it is put in wait state and the fixer is restarted (if ned be) and refills the TB. When it's valid the executor is allowed to come out of wait state (a very slow memory fill). When the 68010 was released we make a small change the CPU board (a couple of PALs) and allowed the executor to actually fault. But the fixer still did the TB fill. But the executor could do a task switch and run some other code, while the fill was taking place. I'm not sure if Apollo updated their original CPU board or just designed a new one with the 68010, I would have to ask some one like Les Crudele to find out for sure. And Sun never did the Forest Baskett dual 68K trick. Sun-1's with 68000 ran a V7 version of swapping Unix (originally from Unisoft) until the 68010 came out when they could support VM on the "SUN-2" and Joy et all moved BSD 4.1 to it. One other note about the MC-500. If was the first commercial Multiprocessor UNIX (predating the 386 bases symmetric boxes but a few years) as well as being the first real time UNIX box. I still have working one in my basement. It has 4 CPU boards in it with a 68010 and 68000 on each, plus a 68000 in the display processor, a number of 29000's in the FP and APP's units, more 29000 logic in the Data Acq Unit, as well as 80186 in the network processor. All in all, a pretty neat federation of processors each doing their thing. Pretty cool for early 1980s' Clem

List Gripes

by chocolatejollis38＠gmail.com

Well, I am once again re-subscribed to this list. Why it or its moderators decide to unceremoniously unsubscribe me every few months without warning is beyond me. Especially annoying when subscription requests always take 2-3 days to process. It would be _really_ nice to do a warning message to people who haven't broken any list rules and haven't asked to be removed before dumping them, especially if this is an automatically-triggered event based on the member's lack of posting activity. Just my two cents.

SDK-86 Chess source code, anybody?

by rdawson16＠hotmail.com

I have the docs and the ROM images from Nigel, but not the source. I did my share of googling, nothing but a piece or two, and not the whole thing. Anybody have this? Thanks, Randy

Looking for SGI Onyx parts

by ian.finder＠gmail.com

I recently picked up a full rack ( https://instagram.com/p/4yEZlYNSxx/?taken-by=tr1nitr0n) It was an awesome project, now that I have a home where I can install 220v. Unfortunately, one of the 4x R4400 @ 150mhz boards is shot, and the System Controller is shot. I borrowed the latter from another Onyx system, but don't like leaving systems in inoperable states. Does anyone have these or other ONYX parts they'd be willing to part with or sell? Thanks! - Ian -- Ian Finder (206) 395-MIPS ian.finder at gmail.com

Search engines index the information from there. Near as I can tell Jay plans on it being online 24/7 and there are no blocks to search engines reading the information and including it in their indexes. Nothing about html format prevents search engines from capturing the information as accurately as text formatting. My point is, that keeping it in text format is not a requirement to make put it in a form that it can be indexed. And I pointed out that some people had warned that all of our discussions were being included in search engines <Google>, as a possible source of objection. I only included that point because the same people lobbying for text form may also be the ones who may not want list traffic in search engines, and I conceded that is a separate point. Apologies to Al for dragging his name into the thread. Not sure where your 2 points came from. thanks Jim

I know there are several people around with the larger VAXes in storage. That's why I asked about the "working condition" - I'm sure the number of big VAXes that could be switched on, say, this afternoon, is quite a bit smaller. FWIW, most 6000 machines weren't even that big. They're smaller than a 780 by quite a bit. I don't know about a 7000 or 10000 - I never actually used one of those in real life. Bob
