I sent this to the CCTECH list maybe six hours ago and haven't seen it yet. I figured I'd try to the CCTALK list just in case, and it is definitely on topic. This webpage goes over the inner workings of a vector graphics generator (as used in arcade games circa 1979-83). Quite interesting: http://www.jmargolin.com/vgens/vgens.htm -spc (Enjoy ... )

IBM 5100 on Ebay

by norm-classiccmp＠docnorm.com

Most likely everyone who'd be interested in this has already gotten notice of it from their saved searches, but ... take a look at http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2026242813 It's a 5100 with BASIC only. As I write this, the auction has 9 days to go and bidding is up to $995 ... yow! Norm

[CCTALK] [CCTECH] scanners & circuit boards...

by Lee.Davison＠merlincommunications.com

Since we are talking about scratched glass, do you have any ideas on how to remove scratches from the face of a CRT? I use Jewelers rouge I got from a Jeweler friend many years ago. It works well on surface scratches such as those you get from laying the monitor on the tube face.

TK50Z-GA and MicroVax 3100/90?

by csmith＠amdocs.com

> -----Original Message----- > From: Ethan Dicks [mailto:erd_6502@yahoo.com] > Perhaps. Large RD-series drives are somewhat rare these days. I will say that with a (pretty common) seagate 40M disk, you can get a bare install of VMS 5.5 on there, and that's more than enough to drive a tk50 and transfer files to other systems over DECNet. Could also netboot it from the other system. > single memory card over 4MB (and only one ethernet module). The uVAX Really? I don't believe I've ever seen one without the ethernet module. That is to say, the cable that comes out of the ethernet ports on all of the ones I've seen is always plugged into something. I know that the ethernet was optional, and that the co-ax/aui ports were there whether the board is there or not. > MMJ adapter is also somewhat hard to find unless you get it with the > computer (it fits over the DA15/DE9 and give you three serial ports > from the mouse/keyboard/console ports) Were they sold apart from the systems? I wouldn't expect them to be available in most cases apart from a system that was sold as a MicroVAX. That said, DEC was supposedly very prolific with these systems, and you ought to be able to get plenty of parts for them. The extreme configurations (color graphics, 8/12[?]MB memory options, etc) are going to be more difficult. The median seems to be b&w VAXStation, ethernet, 4M RAM option. That kind of thing ought to be pretty easy to find. The "box" that the 2000s set on, which exposed the SCSI port, etc, is a bit harder to find, but there are a few around. More common on the "MicroVAX" variant, so if you have the choice, go for one of these. (Unless, of course, the VAXStation would give you the color framebuffer, or a large memory board) Also, you have a better chance of finding a disk in the "MicroVAX" systems, too. The VAXStations (more common too, I think) were lots of times run diskless. It's interesting, because they put "load boards" in them for that. Basically these are resistor packs that load the PSU up so that it won't panic due to the lack of disks. They're nice to have for -- for instance -- running a system with no disk, or use with Wolfgang Moeller's SCSI drivers for these systems. (Which I've not tried yet, but will eventually, supposedly, you can put SCSI disks in them that way. It's _very_ unsupported, of course :) > If all you want is a disk formatter, though, a uVAX-2000 with no > ethernet, 4MB of RAM and no disk should be cheap. Honestly, any 2000 you find will probably be reasonably cheap (like in the $20 range, max) At best, you'll find one in a scrap pile somewhere. They're solid systems, so even if it's gotten left in a warehouse for ages, I wouldn't expect much trouble with it.

Free stuff!

by root＠diablonet.net

Hi everyone! I'm not sure if this list is even active anymore, but let's hope that this message will get routed to its proper destination. Essentially, I'm cleaning out part of my basement, and I have a ton of stuff that I really don't want anymore. I am offering it free of charge to anyone willing to come out to Kalamazoo, Michgan and pick it up. Here's what I've got: * IBM PS/2 Model 50Z, partially stripped. * NCR System 3300, no HDD (scsi), floppy, or MCA cards. * DEC VT420, some scratches on screen but works AFAIK. * Apple Power Mac 7200/90 and 7200/120, stripped, although if someone wants them, I'll put them more or less back together sans RAM and HDD (scsi). * IBM ThinkPad 750 laptop, for parts. * Compaq Contura 420CX laptop, for parts. * Toshiba T3100 (gas plasma screen) laptop, for parts. * Roughly three large cardboard boxes full of boards, including some of the following items. 1. 8088, 8086, 80286, 80386, and 80486 motherboards and CPUs 2. LOTS of ISA cards, including video, I/O, hard disk controllers (even some hardcards), LocalTalk cards, networking, etc. 3. Some VLB cards, mostly video, although some I/O and hard disk controllers are also around, I believe. * Data General dual 5.25" floppy drive, rack mount. I don't know if it works or not, but it seems to be in good condition. * USRobotics TotalControl rackmount chassis with network management card, around 15-20 modem cards, dual power suppies, and some other stuff. I've got a bunch of cables for it, too. I'm currently using it as a table, but if someone wants it, I'd be glad to get rid of it. :) * Token ring hardware -- lots of nice 3Com/Madge/Proteon cards and some MAU/CAU units. * Some other stuff, maybe -- PS/2 Model 5x and 70 systems, Commodore 64 equipment, etc. In general, I've got a TON of stuff sitting around here that I'd really like to get rid of. If there's no interest, most of it's going to go in the trash in a couple of weeks here. If you might be interested in paying me a visit (or having a proxy do so), please contact me and we can get something worked out -- I hate throwing stuff away, but I really want the space! Thanks! Sean BTW -- I've also got a fully loaded, functional PDP-11/34a system in my basement and a broken RX02 dual 8" floppy drive laying around. I'm not really looking to get rid of it PER SE, but I do realize that I will probably never do much with it. Therefore, if anyone might be interested in making trades of interesting equipment (e.g. larger SGI systems, LISP machines, strange Xerox computers, etc), please contact me as well, and perhaps we can get something worked out! -- Sean Caron http://www.diablonet.net scaron(a)engin.umich.edu root(a)diablonet.net

need a map through the MSV11 Qbus memory jungle

by gunther＠aurora.regenstrief.org

[This is a repost because classiccmp ignored it the first time around. I tries cc to cctalk just to test. And copy to Jay West to be sure he gets an exact copy of the message I'm sending.] 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.

AMD 2901 Microcode Meta-Assembler

by dwightk.elvey＠amd.com

>From: "Ken Seefried" <ken(a)seefried.com> > > >Does anyone know of a free or cheap, usable meta-assembler for AMD 2901 >microcode? Or anyone have one they want to get rid of? > >Ken > Hi Ken I wrote one once in Forth for a 2901 project. It was relatively trivial ( at least in Forth since the essense of Forth is to change Forth into the application and not to write the application in Forth ). It would be difficult to have a good general purpose meta-assembler since the variety of ways to wire up a bitslice are so great that a "one size fits all" would be difficult. In my case, I just coded up the bit fields of my controller ( some of the bits ran outside hardware ) with meaningful names. It put things into a binary image file that I first blew EPROMs with and later, after debug, faster ROMs. I was years ago but these really are not that hard to write. Dwight

The main reason I scan at 600 dpi and not save space by dropping to 300 dpi is that the current crop of OCR software seems (in my limited experience) to produce better results with 600 dpi. (I cannot go higher than 600 anyway, but I probably would not bother with 1200dpi because the OCR stuff I have won't even accept it). I'd rather scan the manuals once and wait 10 years for OCR to get to the stage that it can handle the docs with maybe one error per 100/pages (rather than the current standard of multiple errors per page ...). I don't really want to be going back and doing it again! The long term goal is definitely OCR. Although by the time it's good enough we may well all have OC48 feeds to the home and C3D recordable 125GB drives so there may be no need :-) >I did notice that many of the moremanuals pages tend to >show a scanning line when the're first displayed, as if true >white is noisy in some way --it either is light grey or contains >significant dot content. Is that when a page is first displayed (i.e. for each change of page) or just the first page? I assume that you download and then view locally (I have issues with both NS & IE when trying to use then to view local PDFs via HTML ... I assume it would be even worse with a download thrown in for good measure!) >BTW thanks for doing all the work! No problem.

They get strange changes of font on pages 2 & 3 - I wonder if the original has that or whether it's just an artifact of the OCR. A mixture of text and background image (which is also text). I wonder if they might be interested in converting the multiple hundreds of manuals that live on the current crop of DEC document web sites ... Antonio

The stuff I've scanned (like m3100ma1.pdf mentioned above) is usually US Letter size and done at 600 dpi bi-tonal (1 bit per pixel). The scanner happens to LZW encode the TIFF file. There is no option to G4 encode. That usually turns out to be 200-400KB/page but it so happens that one page in that manual did not look too good. So I redid that one page as greyscale (8 bits per pixel) and that just so happens to be over 50% of the total file size (i.e. wipe that one page and you are looking at more like 400KB/page). It's only 14 pages or so, hence one greyscale page makes a big difference. I've seen someone else quote figures of 50-70KB/page for G4 encoded 300 dpi scans of TOPS manuals, which I assume are the typical US Letter size. Obviously going to 600dpi might be expected to produce a factor of 4 increase (i.e. 200-300KB). Or it might not - who can say with compression! I don't see a SC41MS.pdf on that page so I have no idea of the scanning resolution or the encoding. >Can one re-convert PDP^HF files? I've found that using Acrobat 5 in the office I can covert PDF to individual G4 TIFFs (although this is *slow* but it is unattended) and I can then re-import these (in groups of 50 max) which is reasonably quick. But it sucks away time. So if anyone else needs them cut down, be my guest :-) For the few that I've had to process manually (i.e. book format, with pages individually scanned as all-odd-ones, all-even-ones) the conversion to G4 TIFF is a part of the process I use to stitch everything back together in reasonable time. In that case I'm seeing a reduction of maybe 25% in size (although I've not tried to measure it on a reasonable sample ... so don't quote me). If the scanner gets an upgrade that allows it to do G4 TIFF, I'll certainly use it. If a tool turns up that can do unattended conversion of TIFF-in-PDF -> G4 TIFF (or better yet, G4-TIFF-in-PDF) I'll certainly use it. Antonio

Any stories of Dayton?

Hi Dan I'm not sure but it looks like it may be a "Standard Bus" type board. I don't recall the pin combinations but it looks like the same form factor. There are a lot of different Standard Bus manufactures and you should be able to get cards and back planes easily. Count the pins and look the spec up on the web and see if it looks the same.

That will prevent an auto-boot, but won't keep the system from operating. It's not serious; just serious enough that they wanted to wait for some console input before going ahead.

If you're getting the prompt, the counting in hex, and the CPU ID (something like KAXXX-XX, I think), you're doing fine in the cable department. I suppose if not, maybe the VAX prints its errors to all the ports on bootup. In that case, it won't take input from that port, and you'll need to get the right cable to tell it to boot. You still don't absolutely have to get the network connected, though.

[Semi-OT] Seeking Alpha Pc 104 Motherboard

by dougq＠iglou.com

The subject of my query isn't 10 years old yet, but since it's DEC equipment and there are many DEC fans here, I'd like to post it anyway. About six months ago, a list member offered me one of these Alpha ATX-factor motherboards for a very reasonable price. As often happens with many of us, the deal has not gone through. If anyone else still subscribing has a cache of these and is willing to part with one I'd appreciate it. I'd prefer a trade for a Calcomp Digi-Board III digitizer tablet with 16-button puck, but I could also trade a Mac Quadra 700 or Quadra 650 (as I have a couple extra). I also might have other trade-worthy items; just write me and we can discuss it.

Rather than pdf, consider using DjVu; it's a LOT more compact (I recompressed some pages from the RT-11 Software support manual that I'd scanned a while ago with DjVu, and went from about 900 Kb/page to 30-40 Kb/page). Needless to say, I was very impressed. 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. Boris Gimbarzevsky

I'm at home now and I've been able to check some manuals, without too much luck though. The "LSI-11, PDP-11/03 user's manual" discusses the KD11-F (M7264) and KD11-J (M7264-YA) which seems to be the same module with no RAM and packaged differently. I don't know whether that's the module used in the 11/780 console. I'm sure it's in one of those manuals, but I bet you can find out quicker by looking :-) It also discusses usage (and jumpering) of the MSV11-B (M7944) 4K memory board. If your LSI CPU is the M7264(-YA) then you probably want this manual anyway. I also have a copy of the MSV11-P User Guide but that discusses the M8067-LA, -KA, -FA which are 256K, 128K and 64K boards. Maybe useful as a general reference but probably not applicable to jumpering your stuff. My random guess is either you have the refresh wrong or the memory board starting address is wrong. Sadly, even if the guess is right, neither of these manuals are likely to help you sort it out. Let me know if you want them ftp'd somewhere anyway. Antonio

TK50Z-GA and MicroVax 3100/90?

Do you have one without any add-in memory option? I've honestly never seen one like that. Again, I have plenty of "spare" VAXStation 2000 stuff, but I'd like to stay away from committing to ship anything just now. The only memory options I have are 2 and 4M boards, which would give you a total of either 4 or 6M. You do know that you can only fit one RAM board in a system, right?

I scanned all those 11/780 docs and sent them along to DFWCUG but the real praise should go to Alain Nierveze who sent copies of the manuals to me in the post for scanning. >These are wonderful in depth description that I had been >searching for and that none of the "architecture manuals" etc. >ever delivered. These are certainly "old-style" DEC technical manuals. They virtually describe the machine down to the individual chips. All we need now is a full set of prints for the VAX-11/780 ... or a full set of tech manuals for the VAX-11/750 (or VAX-11/730) and someone can then do a full implementation in an FPGA :-) Antonio
