If any of the serious Big Iron collectors are interested in a Convex there is one being decommissioned in Houston. This will be a large hall. If no one picks this thing up it will sit in the Houston weather for a year or so and be melted down. This is the second Convex I've run across in the last few months, surely not many more left. If your serious about moving a few thousand pounds of supercomputer Email me for the details. --

AS400-C10

by thompson＠mail.athenet.net

The above item fell into my possession today. It appears to be circa 1990, contains three hard disks (or DASD, if you prefer), a 150mb QIC tape drive, and a twinax interface card. The IBM web site indicates this machine supports a whopping 20MB of RAM and 2GB of hard drive space. It still has an OS on the disks if I can remember which drive went in which bay in the machine (or if the id is in the drive rather than the backplane) The IBM site is not forthcoming on additional details on the machine.

[ClassicCMP] Does RSX-11M 4.0 support MSCP drives?

To > the best of my knowlege RQDXn are interchangeable Maybe it depends on the firmware then, but I can assure you that the bug certainly exists, and lots of people other than me found it and suffered >from it. The particular bug is that the RQDXn (and other MSCP controllers) return some flags in the top 4 bits of the SA register during initialisation. On the RQDX1 and RQDX2, the rest of the register contains zeros, and the driver code depends on that -- IIRC, there are three places where it does a BNE on the result. The RQDX3 of the same vintage as 5.01, however, returns the interrupt vector in the bottom bits of SA, so the BNE doesn't work as desired. Actually, there's slightly more to it than that, but that's the basics. -- Pete Peter Turnbull Dept. of Computer Science University of York

Upon the date 12:13 PM 2/6/00 -0800, Zane H. Healy said something like: >> The list still here? I have a hard time believing zero posts since last >> night. And then Christian Fandt graciously replied, astutely noting that: > Well, everybody was plumb wore out from all the list operation discussions :-) Boy, I'll say. I skim through the digest keying on the text 'Subject:'. I wore out one mouse trying to get through the likes of: : Subject: Re: [ClassicCMP] Re: ClassicCMP Re: [ClassicCmp] Tag requested in Subject: line : >> I am aware of no mail filters which only allow filtering on Subject:. > Seems to work very well now! May even be good enough to discuss the collection, restoration, and sharing of knowledge about classic computers. I have been on this list since mid-97, and Zane & Chris probably just as long, if not longer. We all know that we don't need '[ClassicCMP]' in the subject line since we have done without for this long. I for one will not debate it beyond this one posting, because it being or not being there makes no difference to me. I might suggest that if there are those wanting to debate it further and if Jay is willing, then set up another list classicmp-admin and discuss away. Meanwhile back at the ranch, I took the trash from my wife's shop out back to the dumpster. I noticed a mouse (two-button, not four-legged) in the dumpster. That led to a keyboard and on to a 386 PC. I know, I know, whoopee! Hey another spare mouse, keyboard, floppy drive never hurts. And there is a small chance that I will soon be hauling home a stack of DECstation 5000's and associated goodies. And one last soapbox point. I do not recall any postings yet, thanking Jay for all the efforts with regards to the list. Given all the flak, I would probably have used the ON/OFF switch by now. Why don't we flood this list one last time with some words of appreciation, and then you can tell all of us about your latest finds, etc. Mike Thompson

[CC] Tags are great

by mac＠Wireless.Com

Actually, folks, the software is -not- so stupid. What happened was that I put on my -personal- subject: line the string [ClassicCmp]. Then Jay added first ClassicCMP then [ClassicCmp]; these are in fact different. Notice: Re: [ClassicCMP] Re: ClassicCMP Re: [ClassicCmp] Tag requested in Subject If people had chosen to be observant, they would have noticed -no- other subject had multiple tags inserted, even when following-up. This is the way it should be. The linux-usb, bsd-usb, and irda lists all use tags, and are very helpful. Again, I don't see what the issue is for inserting [C] or [CC] at the beginning. As for this robbing people of 4 characters on the subject: line - gimme a break! (Or should I pop into flippant mode: what, -you- don't use 132-column screens to read your email! How primitive!) ;-) -Mike p.s. For the humor impaired, please note the ;-) on the previous paragraph.

Full RQDX3 support was not in the *base* system until V5.2.

It took me ages to >trace the problem and fix it :-). MSCP support was added in V5.0 -- but there were some problems, not the least of which was the fact that it setup the interface such that if you didn't do any disk access for a minute, the disk would go off line. This was corrected in a patch for V5.0 and in the distributed V5.1, at which time it also worked with RQDX2... support for RQDX3 and other similar interfaces wasn't out until V5.2...

Re: > This is the way it should be. The linux-usb, bsd-usb, and irda lists all > use tags, and are very helpful. But needless. A decent mail program can filter based on sender, so the message subject is redundant information. That should be "QED", but... > As for this robbing people of 4 characters on the subject: line - gimme a > break! It matters! Pegasus (3.12), even on a 21" monitor running 1600x1200 seems to refuse to display more than about 35 characters of subject heading in a folder (no matter how wide I resize that column of the window) ...why? I don't know! In short, when people complain...sometimes it's because they have a valid reason to complain. (Sometimes, of course, they don't :) sieler(a)allegro.com Stan Sieler sieler(a)allegro.com www.allegro.com/sieler/wanted/index.html www.allegro.com/sieler
