IBM PC rear trim panels… Why are they uncommon?

by nf6x＠nf6x.net

It seems to me that a large percentage of original PCs, XTs and ATs that I've ever seen have been missing the plastic rear trim panels. Is there any particular reason why those seem to have been so commonly removed and lost or discarded? -- Mark J. Blair, NF6X <nf6x at nf6x.net> http://www.nf6x.net/

Terminal emulator for TRS-80 Model 1?

by fozztexx＠fozztexx.com

Somewhere in the last couple of days I saw mention of a terminal emulator program for the TRS-80 Model 1, but I don?t remember what it was or where I saw it. I didn?t think about it because I was able to get kermit on the TRS-80, but I just pulled it out again and kermit kinda sucks. It types in all uppercase unless I hold down the shift key, and it?s got no cursor. Anyone know of something that?s better? Follow me on twitter: @FozzTexx Check out my blog: http://insentricity.com

Needed: Diagnostic listings for DEC RL controller&disk drives

by j_hoppe＠t-online.de

Hi all, I'm trying to repair a bunch of DEC RL11 controllers. (These are the UNIBUS boards for RL01/RL02 disc drives). Running the PDP-11 diagnostics ZRLA, ZRLB, ... ZRLN from XXDP or papertape prints out some errors, but without the diagnostic assembler listings I don't understand what's wrong. At the moment I know only of these 4 listings: AC-E040B-MC_CZRLBB0-RL11_RLV11-Controller-part-2_Oct78.pdf AC-E044B-MC_CZRLCB0-RL01-Drive-Test-part-1_Oct78.pdf AC-E048B-MC_CZRLDB0-RL01-Drive-Test-part-2_Oct78.pdf AC-E246B-MC_CZRLEB0-RL01_RLV11_Exerciser_Oct78.pdf These are all for paper tape based MAINDEC diagnostics, and are also incomplete: At least both "part 1" AND "part 2" is needed for ZRLB, ZRLC, ZRLD. Can you point me to some hidden archives? Or do you have more assembler listings for ZRL diagnostics lying around? Bitsavers needs your input! Thanks, joerg

New Sun Docs Posted - Hardware too

by silent700＠gmail.com

Three new Sun binders scanned tonight with a pair of special docs this time. It's all been software previous to these but tonight we have the elusive (at least I couldn't find it) Sun PROM User's Manual (doc# 800-1736-10.) This one has lots of juicy info going back to the Sun-2 (including the LED flash codes I'll need to diagnose my -2 boards) up through some of the Sun-4 series and the 386i. I'm sure a lot of that info is out there in FAQs and Usenet posts but this may be the source of that knowledge in one place (not to discount personal experience.) There is also a system diags manual that spans a few platforms as well. And riding along with these two is the "Editing Text Files" tome, covering your favorite editors of the period. The filenames are here: 800-1736-10_SunPROMUsersManual_RevA09May1988.pdf 800-1738-10_SunSystemDiagnosticsManual_RevA09May1988.pdf 800-1754-10_EditingTextFiles_RevA09May1988.pdf and the files can be found here: http://chiclassiccomp.org/docs/index.php?dir=%2Fcomputing/Sun Enjoy! -- silent700.blogspot.com Retrocomputing and collecting in the Chicago area: http://chiclassiccomp.org

VCF Midwest 2014

by silent700＠gmail.com

Hello ccmp'ers - July is almost here and that means it's time for me to start making noise about our yearly Midwestern weekend-of-fun. This year's Vintage Computer Festival Midwest will be held a bit earlier than in previous years, owing to the usual scheduling conflicts with holidays and other events. The weekend for 2014 is September 13-14. Those coming from out of town and staying over night should call the hotel ASAP. Registration at the group rate has been open a few weeks now but last I heard rooms are still available. If you would like table space, please email me privately with your requirements and what you'd like to display and or sell. Most of the provided tables are 2'x5'. If you can bring your own folding table, please do! We run out of tables before we run out of space to put them. We've got a new site up with actual content, including an ever-expanding FAQ. Have a look and feel free to post about anything not covered there: http://vcfmw.org See you in September! -j -- silent700.blogspot.com Retrocomputing and collecting in the Chicago area: http://chiclassiccomp.org

IBM PC rear trim panels? Why are they uncommon?

by afahimi＠alumni.usc.edu

> To the best of my recollection, the 5170 in its native form did not > include a trim panel. However, it was included (ISTR anyway) with the > "sit the box vertically on the floor" IBM kit. > >--Chuck Those were actually two different options. The grey back panel came standard with all 5170 AFAIK. Since they were only put on by Velcro most are lost (like the front lock keys). The tower option (or as it is formally known: Personal Computer AT Floor Standing Option 6450218) allowed you to stand up the 5170 on its side. In fact you cannot use both the grey back panel and the Floor Standing Option together. Check out VCF - I have pictures of both of posted.

CompuServe Magazine Scans

by silent700＠gmail.com

I am very pleased to announce, and be done with, the scanning of a small stack of CompuServe Magazine, the magazine sent to subscribers of the online service of the same name. There are 19 issues in all, various months from 1990, 91 and 92. They're full of ads for "The Mall," CompuServe's online shopping service, with a good sampling of the products of the times. The articles cover a wide range of topics (and how they're accessible on their service) as well as predictions of CompuServe's existence for decades to come. Not much mention of this "Internet" thing... Due to the size of the files and the ease of reading documents in their browser, I uploaded the scans to archive.org instead of our usual docs site. All of the issues should be accessible with this search: https://archive.org/search.php?query=compuserve%20magazine Enjoy! - jht -- silent700.blogspot.com Retrocomputing and collecting in the Chicago area: http://chiclassiccomp.org
