missing chips on "new" UNIBUS boards ...

by gunther＠aurora.regenstrief.org

Hi, gee, in my zealous bargain-hunts I keep being burned. Two bad CPUs before and now I thought I had a bargain with two UDA50 sets another KFQSA and a DEUNA set. However, as I unpacked yesterday, I noticed that the KFQSA was missing one socketed chip (approx 40 pin DIL, black right in the middle.) Also, one of the UDA50 boards the M7.65 I think is missing a whole set of 10 or so socketed chips all of equal size on the side. My hope is that those are ROMs that may not be needed unless booting from KFQSA or DEUNA is required, but that's a very remote hope. Can they be replaced? Probably makes no sense. grrr, -Gunther -- Gunther Schadow, M.D., Ph.D. gschadow(a)regenstrief.org Medical Information Scientist Regenstrief Institute for Health Care Adjunct Assistant Professor Indiana University School of Medicine tel:1(317)630-7960 http://aurora.regenstrief.org

NeXT (Almost-up-and-running-now) Laser Printer

by csmith＠amdocs.com

Ok, I reset the netinfo database -- now as soon as I can get it to give me a login prompt again instead of kicking me into the 'me' account at boot I'll be in business there, but my NeXT b&w laser printer is somewhat cranky. Having not been used for years, I can see how this might be... Here are it's problems: Paper feed roller doesn't like to work well all the time. I'm certain that this problem comes from the printer setting too long, and making an indentation in the rubber on the roller. Has anyone had success in repairing this kind of thing? The printouts have black in the wrong places sometimes; fused, but -- well, basically it looks like a bad photocopy :) Sometimes the misplaced ink will have an imprint from another part of the same page, or from the previous page. There are also "splotches" of white here and there in the good printouts where there should be some toner. I imagine something may be dirty, but not knowing a lot about laser printers (aside from keep away from the fuser when it's operating...), I don't' know where to start looking, nor would I necessarily know how to clean things up if I found the right spot. Any ideas? Chris Christopher Smith, Perl Developer Amdocs - Champaign, IL /usr/bin/perl -e ' print((~"\x95\xc4\xe3"^"Just Another Perl Hacker.")."\x08!\n"); '

AIM-65 displays

by dwightk.elvey＠amd.com

Hi Rich and All I found a list book as well in my pile but I'm glad someone else has it up on the net. I was concerned about copying it because of the weak binding. Looking at the other AIM-65 stuff I have, I found ROMs for BASIC, Forth and PASCAL. I have manuals for the BASIC and Forth is Forth so doesn't need a manual but I have no manual for the PASCAL. I can make dumps of these ROM's if there is interest.

(rarity? > inability to > run MICROS~1 software? weight? unknown to the general population? Well, I generally include inability to run microshaft software when I'm trying to figure out how cool a system is. Those that you can get a winders emulator for generally rank above those that run it natively, and those that you can't get an emulator for above that, A.S.O. -- I'm not sure how you'd turn that into a number to be used in a calculation, though. Perhaps that would be going the wrong way -- it would be simple just to find the minimal amount of internal storage required for a "supported" system, in comparison to the space required by the full system, and to subtract from the score based on that number. That would certainly harm more "modern" systems which run microsoft software ;) This "internal storage density" would probably be something like: (<Fixed-Media> + <RAM> + <ROM>)/Meters^3 (where the storage should be represented in some suitably large or small unit) Christopher Smith, Perl Developer Amdocs - Champaign, IL /usr/bin/perl -e ' print((~"\x95\xc4\xe3"^"Just Another Perl Hacker.")."\x08!\n"); '

The original post seems pretty innocuous to me and if you read it closely, you would have figured out that the poster and the person who had the machine were two different people. The poster (in my opinion) was just trying to share a find with someone who might be interested in saving a classic from the scrap mill. I have dealt with the person/company who was making the offer to save the machine for a profit, and yes that is what companies do. This guy is paid to make money for his company. I had an email conversation with him and it would appear that they bought some of the parts from the machine for resale to their customers and this guy put some enough extra thought into it to think that there is this group of crazy collectors our there that might be interested in the machine. Yes he is probably thinking from a profit point of view, but at least he is thinking of us. There are so many of these guys that don't think of us and end up destroying old machines which would make great projects for someone on this group, that it make me ill. Further, in my mind, the endless number of worthless flaming messages which were spawned by a list members attempt at providing a pointer to an available machine is *far* worse than an infrequent piece of spam, which we ought to just ignore. Can't we all just enjoy our hobby instead of ragging on each other? --tom

Well... as employee #4 of Byte Shop #4 (Portland, Oregon), and the one there who had to make various of that first batch actually do something interesting... <G> I can offer a few observations on this: As I recall, all of the Apple-1 units that came through our store were pre-assembled. I seem to recall someone asking about kits, but the 'party line' at the time was that Apple (I seem to recall the comment being attributed to Woz) considered it too difficult to assemble (without damaging it) for the 'average' customer. Keeping in mind that whoever actually bought one of the things had to figure out how to connect a (parallel) keyboard to it, plus the video and cabling for the cassette recorder. What you may have been thinking of was the occassions where Woz passed out schematics at the Homebrew Computer Club meetings for anyone who wanted to try to assemble on on their own.
