DEC machines that can't format a disk (Was: Good Trip/Score Dec Rainbow...)

That the systems can't format their own media, I mean :) Chris Christopher Smith, Perl Developer Amdocs - Champaign, IL /usr/bin/perl -e ' print((~"\x95\xc4\xe3"^"Just Another Perl Hacker.")."\x08!\n"); '

Very true. I like DjVu, and was the source (I think) of Boris finding out about it... But I still prefer PDFs. I scan text-only pages at 600dpi in line-art mode, which creates hi-res bitmaps instead of greyscale files. While intuition might say that greyscale is better, when printed, most people will not be able to tell the difference. For pages with extremely detailed info, I use 1200dpi line art; for photos, I use greyscale, and do my best to clean them up. Halftone images require de-screening. -dq

computer sales -- now only on e-bay???

by bfranchuk＠jetnet.ab.ca

Is the classic computer sources finally drying up to become E-bay collector items only so most people can't see a real machine anymore? -- Ben Franchuk - Dawn * 12/24 bit cpu * www.jetnet.ab.ca/users/bfranchuk/index.html

The scanner I use produces LZW compressed TIFFs and wraps them in PDF - that ends up in the 200-250KB/page for US Letter size at 600dpi. Getting to 30-40KB/page with *lossless* compression would certainly be very impressive. However, it's taken pdf quite a while to become the defacto standard. I doubt that it will lose that mantle until something else comes along with (at the very least) an openly published spec. Anyway, I use PDF because that's what the scanner gives me. If someone wants to convert to some other format, that's absolutely fine by me. >The DjVu viewer plugin for various browsers if free, and a program which scans images to individual files is >also free from http://www.djvu.com/. I first heard about DjVu on this list, and it is one of the neatest >pieces of compression software that I've seen. Thanks for the pointer - I'll try to give it a go sometime soon. Is the compression lossless (I took a quick look at their pages and could not tell). Is the format published i.e. could I write my own viewer. I don't think I would want to, but I'd be much happier if I knew I could if I absolutely had to (I didn't see any OpenVMS support on their pages ...) Antonio

need a map through the MSV11 Qbus memory jungle

by gunther＠aurora.regenstrief.org

Hi, in my VAX 11/780 I have the PDP-11/03 alias KC780. And it has the following memory board right now: M7944 MSV11-B Q 4-Kword 16-bit MOS RAM (external refresh) But, since I'm planning to upgrade to an 11/785 I need additional RAM. When it showed up on ePay I buyed a M8044-DA MSV11-DD Q 32-Kword 16-bit MOS RAM but the boot program will not load with this. Why would that be? From the error I got it appeared as if may be there is just some jumpering to do, but I have no clue as to where and what. Looking at the UNIBUS/Q bus field guide beginning from M7944 and then scanning forward to the next MSV11 I find: M7955-AD MSV11-CD Q 16-Kword 16-bit MOS RAM with on-board refresh and then the family of M8044s M8044-AA MSV11-DA Q 4-Kword 16-bit MOS RAM M8044-AA (Also M8044-AB, -AC, -AD) M8044-AA Refs: EK-MSVI1-OP, MP-00566 M8044-BA MSV11-DB Q 8-Kword 16-bit MOS RAM M8044-BA (Also M8044-BB, -BC, -BD) M8044-BA Refs: EK-MSVI1-OP, MP-00566 M8044-CA MSV11-DC Q 16-Kword 16-bit MOS RAM M8044-CA (Also M8044-CB, -CC, -CD, -CE, -CF, -CH, -CL, -CM) M8044-CA Refs: EK-MSVI1-OP, MP-00566 M8044-DA MSV11-DD Q 32-Kword 16-bit MOS RAM M8044-DA (Also M8044-DB, -DC, -DD, -DE, -DF, -DH, -DL, -DM) M8044-DA Refs: EK-MSVI1-OP, MP-00566 Does that mean that I should have the M7955-AD RAM instead? This is confusing. And I'm not even asking for Q22 bus or PMI memory stuff. What's the thing I'm missing? thanks, -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

There's some 780 console information at DFWCUG too, but I doubt that it covers this (it's at home and not to hand right now so I cannot check). I do have an 11/03 user guide (with a fair bit of technical info - it's a -TM- part number) and I can ftp that to you if it might help. I can look in it tonight to see if it has any helpful comments. I can also ftp it to you if you don't fancy waiting a month or so for it to appear on DFWCUG. Antonio

>Well, I'd appreciate it. I do have the M8189. I have found the specs on >that (really brief ones) but they don't tell me enough. The PDF would be >handy. I have the individual pages scanned, I just need to clean it up and put it all together. It should be done by the weekend. Do you have anywhere I can FTP it to? The full manual will be in the region of 200MB. Otherwise you'll either have to wait for it to make it across to the DFWCUG site (maybe another month or so) or I can extract the first couple of chapters which cover specs & installation. That's maybe 30 pages or so and will be between 5MB and 10MB - probably small enough to email as two PDFs (assuming your end can handle that).

Thanks a bunch!

by gunther＠aurora.regenstrief.org

Whoever scanned the KA780 and FP780 "Technical Description" documents and put them up on the moremaniuals site ought to be given thanks and praise! These are wonderful in depth description that I had been searching for and that none of the "architecture manuals" etc. ever delivered. In the end the KA780 description may even obviate how to do the kind of microcode programming that I would like to try, may be to implement some part of a Java virtual machine as native KA780 machine language. (JaVAX-11/780, the true javax :-) cheers, -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

found VAXStation 3100 M38 memory

by zmerch＠30below.com

Rumor has it that David Woyciesjes may have mentioned these words: >This guy thinks this set will put the VAXStation3100m38 up to 32 MB >of RAM... Well, it's hard to say if *his* set is the full monty, but I just *happen* to have a VAXStation3100/m38 with 32Meg in it, so it is possible! Shipping on the rest of the VAX shouldn't be that bad -- it's a fairly bulletproof system, and not that big... >And good news is he's got RAM for auction, for my DEC 3000/400! Woo-hoo! Sure... I'm sure you didn't post _that_ link to keep me bidding against you for that -- for my DEC 3000/300! Mine's only got 64Meg; and I heard VMS is rather doggy in that amount... (tho I'd doubt that it'd be any worse than Tru64 Unix, but that's just speculation...) Laterz, Roger "Merch" Merchberger -- Roger "Merch" Merchberger --- sysadmin, Iceberg Computers Recycling is good, right??? Ok, so I'll recycle an old .sig.
