Hello. I'm not sure if this is the correct list to ask about this, but I accept suggestions about the matter. I have one Sun3/50 and a couple of Sun 3/60. No disks or monitor. I know that they use ECL monitors. In fact I have the ECL cables, plus one Extron RGB device to (supposed) connect them to other kind of monitors as VGA and so. Someone has experience about this matter ? Related resources ? THanks and Greetings Sergio

Graphics Collector

by rborsuk＠colourfull.com

Who's our graphic's system collector on the list? Wasn't there a Richard or someone? I'm going through an old box of documentation of mine and I want to send the graphic stuff on to someone who collects/ scans/and post this kind of stuff. It's stuff on graphic chips, acceleration, etc. Glint, PowerVR and others. Please write me off the list. Thanks Rob Rob Borsuk email: rborsuk at colourfull.com Colourfull Creations Web: http://www.colourfull.com

Do you have a rackmount SGI Onyx RealityEngine2?

by jplist2007＠kiwigeek.com

If so, Uncle Sam wants you! Well, not really. I'd be immensely appreciative if someone with one of these could take a quick gander at a couple of things for me. To get mine back to functioning order I need to know the following to make certain I have the right parts. Please note this is specific to an RE2 Onyx - the IR Onyxes definitely had different Power Boards. The VTX may too, but I'm not positive - better to be safe than sorry later. 1) The number and types of Power Boards in the upper front card cage. (512, 505, 303, etc?) Part numbers would suffice. 2) The part numbers of the Online Switchers (located on the top of the OLS after it's been slipped out). And that's it! Many, many thanks to anyone who takes the time to whip out a screwdriver and take the front panel off their Onyx to let me know. JP Hindin

That poor system/36

by ceby2＠csc.com

John / all, Sorry I've been lurkin' on this thread for a bit, though thoroughly amused that 2 years after I listed the system I can finally say, yes I have a taker. Or I think I do -- hence I put John's mind at rest by retiring the listing. If anyone had checked the cctalk archive, you'd see I was whining on the very subject of this system a couple of weeks back (see http://www.classiccmp.org/pipermail/cctalk/2007-September/245969.html). I'm afraid the collective amnesia on this point was kinda amusing me. Rest assured the system is safe (to the best of my knowledge... I'm 4000 miles >from it and haven't check on it for a couple of years). Regards, Colin Eby

Amdahl Mainframe - The great trip

by rborsuk＠colourfull.com

Curse you who mentioned this Mainframe on the list. My love of big iron couldn't let it go to the dumpster. Check out the trip for this monster on my family blog at http://www.borsuk.us Any ex-Amdahl administrators out there?

Any Vector Graphic experts out there?

by dm561＠torfree.net

I've got a Vector MZ with a ZCB processor and BitStreamer II I/O board; at present the 4.0 'C' series monitor program uses serial port A on the BitStreamer for its console, but I want to remove the BitStreamer and use the serial port on the ZCB instead. At a fast glance I can't see a jumper setting that would accomplish that; anybody out there have any experience/ideas by any chance? TIA, mike

Ferranti Logical Computor (1951)

by gtoal＠gtoal.com

Here's a very interesting 1951 paper on the construction of a complex boolean logic unit using relays. It's contemporary with the more better-known Kalin-Burkhart machine. http://history.dcs.ed.ac.uk/archive/docs/mechanized_reasoning_screenres.pdf This is the first time this paper has been put online. I received it as a photocopy of the original from J B Smith's sister. This is at screen resolution. I'll post a higher-res version later for printing. (I had to clean up the paper considerably from the original using Photoshop.) If you're interested in the history of logic machines, you should also look for machines by Alfred Smee (1851), and William Stanley Jevons (1870) Graham References: http://www.google.com/search?source=ig&hl=en&channel=2PSP&q=Kalin-Burkhart http://www.google.com/search?hl=en&safe=active&q=%22mechanized+reasoning%22…

Today's hackers (was: Taken: AT 286 motherboard with mathco)

There might be more projects overall, >but the number of projects in comparison to the number of people who just >use their computers as toasters as a ratio is lower. >But as you're not convinced for anything for any reason, it would be >pointless for me to tell you about it. ;-) --------------------- No, you can't *convince* me because I already agreed with your viewpoint ;-). What are you "disagree"ing with? I think you said exactly the same thing I did, that it's almost certain that more people are digging into their computers today than back then just because there are so many more people with computers, while it *is* probably true that for various reasons fewer people who own or have access to computers are tinkering with them. Maybe you missed my original post where I said, "perhaps the *percentage* of computer owners who dug into the hard/software was higher then, but most of the time you *had to*, whereas today most of it is done for fun and enjoyment, as well as pride of accomplishment." (Note the "probably" and "perhaps," since I *don't* have hard numbers ;-) Since you're picking nits, I'll even amend that to "almost certainly;" happy? Computers are more reliable and harder to tinker with at the hardware level today and people have a lot more options how to spend their spare time; so what? There's still a lot more overall activity and with all the forums and Web sites like this one it's a lot broader, more fun and not as socially isolated today, at least as far as I'm concerned; hackers like us were probably (!) more outside of the mainstream back then, and the chances of someone understanding what you mean by GHz or MBs are probably (!) better today. I still don't see why case mods, seeing how far you can push speed with water-cooling etc., or programming a CPLD instead of burning your fingers on a hot soldering iron should be excluded; that sounds a little like old-fogey-ism to me. Times have changed and folks are doing what's relevant and possible today for mostly the same reasons and satisfaction as then; more often than not that involves modern approaches to *old* hardware & software because it's almost impossible to do some of the things we used to, due to the complexity, inaccessibility and lack of documentation of most of today's hardware. I think a lower percentage of people having to spend time dealing with flaky and unreliable hardware, poor/buggy software and tools, incompatible disk formats, etc. is a good thing; my enjoyment of that sort of thing may well be a symptom of a mental disorder. Sheesh; like I said, 'nuff said. m
