Hi All, Today at the preview for the UA auction tomorrow, I saw one bigass DG Aviion. I believe it is a 9500+. I pulled the cpu board from the back of the VME bus and it showed 4 (four) 88110RC50F motorolla processors, which I believe are 50Mhz 88110's. It also had about 523MB of memory. but no disks. Usually these rack-size monsters go for next to nothing > $25.00, sometines as low as $2.50 Any takers ??. For a small consideration I can buy and hold as obviously you don't want to ship it. Cheers Tom -- --- Please do not read this sig. If you have read this far, please unread back to the beginning.

I am also in need of one of these for a pdp-8 (16 sector packs). I don't want to keep it, just use it. Is there a way that someone could create one of these for people who might find these useful?

looking to trade for paper tape reader/punch

by jwest＠classiccmp.org

I'm looking for a standalone paper tape reader/punch combo. Something along the lines of like a DSI 2400, but I'd really prefer a facit 4070. Must have Rs232 interface. Perhaps I could trade a tested/refurbed HP21MX cpu for one? or?? Jay West

Is there a way that someone could create one of these for people who might find these useful? -- Crisis Computer in San Jose has the equipment to write CE packs. They aren't going to be cheap. I'm guessing $300 to $500. They are probably the only place in the world left that has the gear to do this. Realigning 2315 heads isn't something you want to do if you don't absolutlely HAVE to, since you run the risk of making the packs that you have unreadable, if they were written on drives that are off spec.

Does anyone on this list have any machine readable copies of RSTS/E besides the v7 one that we use with Bob Supnik's simh simulator? I am looking for some of the older versions, such as 6A, 6B, or 6C. I have v7, but in order to recreate an accurate reincarnation of what my group used in 1977-79, I need the v6 versions.

Am I overlooking any options? JPEGs are bad news because of the losses. Personally I find higher-resolution easier to read (and print, if I want to, which I often do) and normally greyscale isn't needed. The last thing I scanned was a 166-page DEC manual, which came out as 6.4MB of PDF or 6.3MB of G4 TIFFs in a single TIFF file. That's a lot better than your 20MB JPEG, and higher resolution, too. -- Pete Peter Turnbull Network Manager University of York

m9312 roms

On Jun 27, 8:13, <pzachary(a)sasquatch.com> wrote: > > I have several roms and a reader, what format would be the most portable? If you mean file format, probably Intel HEX files. I usually use binary for ROM images, but those ROMs are small so it's not really an issue. More programmers handle Intel HEX than S-records (though some handle both, and there are various utilities on the net, including mine, to convert between them). If you mean data layout in the file, remember those ROMs are 4-bit wide. A lot of programmers only use one half of each byte in the file. Mine happens to use the lower 4 bits, but I believe some may use the upper 4 bits. It might be worth copying whichever 4 bits your programmer provides into the other four (ie if the data in one 4-bit word is binary 1011, and the programmer creates a file with byte value 00001011 for that word, turn it into 10111011). You'll end up with a file that's 512x8 instead of 512x4, of course, but you would anyway, as that's what most programmers use for such devices. -- Pete Peter Turnbull Network Manager University of York

Mount disk images for MS-DOS

by cfnelson_87111＠yahoo.com

I know there are lots of utility programs that can create image files of floppy disks for MS-DOS. Instead of having to write the image file back to a physical floppy disk, are there any programs that can "mount" disk images to make it appear to MS-DOS as if the original floppy disk is in a drive? As an example of what I am looking for, "Disk Copy 6.x" can do this for the Macintosh. - Curt __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

Rejuvinating Lead/Acid Batterys, was Re: HP-110 Plus laptop power supply specs?

by dwight.elvey＠amd.com

Hi Marvin Most gel cells are damaged from overcharging and not sulfating( no more water inside ). Most cases of sulfating can be recovered with a slow, low current charge. You need to have just enough current to overcome the normal leakage but not enough to generate excess gas. I've not seen, personally, enough difference between these types of battery rejuvenators and just using a trickle current to justify there purchase. About 5 years ago, we took two batteries that did not recover after a trickle charge. Neither of the two recovered after using a device, similar to the one described with high frequency pulses. All the other batteries recovered. These were auto sized and we used a current of 200ma.

Mount disk images for MS-DOS

by trash3＠splab.cas.neu.edu

I think something similar would be Ghost Explorer. That lets you take a drive that has been "backed up" with Ghost (sorry, no floppy drives that I know of) and then treat the packed image file as a folder (under Windoze). I think you can also "zip" the files on the drive and then use an unzip program to browse. But it sure would be nice to take a file made by a true floppy image copy program (like floppy copy) and browse it, not just restore it to another floppy. Joe Heck

Dec VAX 4000/500 cluster rescue

by Mark＠Misty.com

Hi, I just rescued a Vax cluster, with two 4000/500 processors and a R400X enclosure with DSSI drives in it. I'm a newbie to VAXen, but ordered CDROM media for OpenVMS as a hobbiest. I also successfully fashioned a console cable. So far, if I boot from one disk, I get a $ prompt, but only with the "backup" command working, and if I boot from another I get tons of boot-up messages, but no console login prompt once the thing seems to be up. I'd like to find four DSSI terminators, so I can run one or the other processor, either with internal disks or the R400X, without having to have this set up as a cluster. I'm also looking for some other SCSI controller. The one in this system is the KZQSA, suitable for installing VMS from a CDROM, but incompatible with NetBSD, and apparently pathetically slow for SCSI hard drives under VMS. I have no idea where to find either of these items. If anyone has any suggestions, please let me know. Mark -- Mark G.

manuals in pdf (resolution, compression)

by aek＠spies.com

I scan at 400dpi 1bpp and save the pages using group4 compressed TIFFs which is the maximum res the IS520 scans at. Acrobat does a really poor job of saving JPEGs (it makes them a LOT bigger than the originals) and I would NOT use a lossy format on any page with only text or line art. There is a noticable loss of edge contrast on text pages compressed as JPEGs.

Floppy drive oddity? (TEC FB-503)

by melamy＠earthlink.net

a thought just hit me as to a typical failure that I have seen in floppy drive controllers. Look at the output drivers on the controller and see what the signals look like. These chips are typically open collector buffers of some kind (7438, 7406, 7407, and peripheral chips 7549x series). I have seen these chips have output problems and that could certainly create problems. best regards, Steve Thatcher -----Original Message----- From: "Dwight K. Elvey" <dwight.elvey(a)amd.com> Sent: Jun 28, 2004 12:33 PM To: cctalk(a)classiccmp.org Subject: Re: Floppy drive oddity?

Upgrading a KDF-11B ROMs for MSCP Bootstrap (disassembling a bootstrap ROM?)

by bob＠jfcl.com

Hi, I have a KDF-11B (that's the quad sized PDP-11/23+ CPU with onboard serial ports and bootstrap/terminator) that's too old to know how to boot from MSCP (e.g. RQDX/RD5x) drives. I know later versions of this board could do that and I was planning to just upgrade the EPROMs on my board, but all the later EPROM images are 8K bytes - my board has only 2K (2716) 24 pin EPROMS. There's no way (at least no simple way) to install 8K 28pin EPROMs. Actually, the EPROM sockets on my board are so close together that I don't think I could get 28 pin devices to fit even if I did "flying leads" for the extra 4 pins. Did the later KDF-11B boards really have 28 pin sockets? Is this upgrade hopeless? Does anybody have a system for disassembling and then re-assembling these EPROMs? If I throw out all the useless bootstraps (e.g. the RK, MRV11 ROM or DECnet boots) there ought to be room even in 2K for a DU boot. Bob Armstrong

Hexbus interfacing

by rcini＠optonline.net

Hello, all: I'm researching ways to interface my TI74 to a host PC. TI made a PC interface cable which I've been able to find from a third-party vendor now that IT is out of the CC40/TI74 business. He wants $94 for it. Way too much for my cheap blood. Sensing a homebrew project in the offing, I've been doing some research. I've been able to find the software for the PC but I've found no info on the cable. The cable probably has a Hexbus chip in it, which knowing my luck is no longer available. The Hexbus specifications ("Intelligent Peripheral Bus Controller" dated 9/83) don't reveal a chip number but does indicate the fab -- LSI Logic. Does anyone have any info on the Hexbus silicon? I've spent some time with the FTP archive on Western Horizon Tech's site but I'm coming up empty. Thanks. Rich

More Amiga 2000 help/info needed.

by netsurfer_x1＠fastmailbox.net

Well, thanks to everyone for their help on my A2000. Now that I've cleaned it out (you wouldn't believe how much dust there was inside!). It seems as though this machine is having some more problems. It now shows the self test screen colors in the following sequence: dark grey-light grey-yellow. Can somebody *please* help me out! I don't want to have to confine this machine to the trashpile! Also, if someone can direct me to a PDF version of the manual, I'd be very appreciative!

manuals in pdf (resolution, compression)

by aek＠spies.com

Using tiffcp to change the compression from lzw to g4 more than doubles the size to 1.6 MB. That's for a single page. -- Something is really broken with what you are doing. A normal 400dpi G4 compressed text page should be 50 - 100k. Scanning though the sizes of a manual I just scanned, it's closer to 15 - 50k / page.

character codes, was RE: Really stupid PDP assembler question

by melamy＠earthlink.net

another reason, the CDC 6400 (circa 1960s) COMPASS assembly language instruction set made sense "opcode" wise to express it in octal. They had 15 bit, 30 bit, and 60 bit instructions with a 60 bit bus. best regards, Steve Thatcher (who does still write in assembler...and most everything else)

Philips P2000C disks

by julesrichardsonuk＠yahoo.co.uk

I think a couple of people expressed an interest in boot disks for the Philips P2000C a few weeks ago. I only just got into the museum stores today to see what we have. Reading off disk labels (I know *nothing* about these machines!)... Specific (original) 2000C floppies I found: Copower disk CP/M Copower disk MSDOS 2.11 Wordstar 3.3 Calcstar 1.45 CP/M 2.2 ABASIC P 2509-L / TTY P 2526-L Grafox Dataplot+ P2000C Maintenance Program MN11 Also the following copies (I have no idea how a P2012C differs from a P2000C!): P2012C CP/M P2012C MSDOS Utilities P2012 Cardbox P2012-16 CP/M boot disk for MSDOS (P2000C mode) <non-IBM MSDOS s/w> P2012-16 CP/M boot disk for MSDOS (PC mode) <IBM PC software> P2012-16 MSDOS (P2000C mode) System disk <non-IBM PC software> P2012-16 MSDOS (PC mode) System disk <IBM PC software> P2012-16 P2012C CP/M MS-boot, MS-util, R/disk copy of master disk P2012-16 P2012C MSDOS utilities copy of master disk P2012-16 Copower disk CP/M copy of master disk P2012-16 Copower disk MSDOS 2.11 copy of master disk P2012-16 CP/M 2.2, Wordstar 3.3, Calcstar 1.45 copy of master disk P2012-16 ABASIC P 2509-L TTY P 2526-L copy of master disk P2012-16 Grafox Dataplot+ copy of master disk P2012-16 Maintenance program MN11 copy of master disk P2012-16 Test pattern disk for use with MN11 maintenance software A lot of those copied P2012 disks sound suspiciously like direct copies of the P2000C originals. What's the difference between the machines? What's the easiest way of copying these? I can put a 360K 5.25" drive in my desktop PC and run off some disk images, assuming they aren't some oddball format which the PC controller can't cope with. What's the best software to use? (I can boot MSDOS, Linux or Win 2k on the desktop) No idea if data is intact on the disks of course, but they're all boxed and look to be dust free. I also found the following P2000C documentation, although scanning is probably out of the question (happy to look stuff up though!): P2000C System reference and service manual set CP/M reference manual MSDOS user guide Copower board reference manual Calcstar manual Wordstar manuals 1 and 2 Disk BASIC reference manual P2000C operator manual Dataplot+ user and reference manual Advanced BASIC interpreter operator manual TTY user guide CP/M user guide P2000C software catalogue cheers, Jules

At least it can format blank media. True more or less, but sells the Rainbow a bit short. It has both Z-80 and 8088 (arguably 16-bit?) processors, runs CP/M-80 and CP/M-86 as well as the DOS you described (and VENIX? Not sure that that is still resurrectable). The "Rainbow" was (according to at least some of their literature) intended to be a bridge between the 8-bit and the 16-bit software worlds. -- - Mark 210-522-6025, page 888-733-0967

DEC & HP available - a trip to an infrequented collecting spot in stlouis

by jwest＠classiccmp.org

I had an opportunity to visit my absolute favorite spot in St. Louis for old puter stuff. It's definitely not open to the public and the opportunity came to get in today so I went. I found some stuff that may well be of listmember interest. First. Pallets and Pallets of DEC disk drives... RD52, RD53, RD54, etc. I even found a case (about 8 drives) that were RD54's that were new or refurbed and STILL SEALED in antistatic bags. There were several mounting trays and rails for these drives, sealed in bags too. There was also some other drives that were RZxx, I don't remember the xx part, and they looked just like RD53's do. Two DEC LA120s (very yellowed) A pallet of IBM selectrics. A really nice microvax cabinet, but it had been stripped of all cards. A bunch of 1/2 mag tapes, 6250bpi , still in original seal. A few HP line printers... don't remember the model... but they are pretty big. Maybe 4 feet tall, about 8 buttons on the top. Looked to be in good condition. Freestanding units built inside a cabinet with wheels. I have seen and sold these before but I'm drawing a blank on the model. I am guessing around 1987 era? This model is known as a tank/workhorse. An odd dec item I've never seen... it was something like TA90Z... I figure it was a tape drive. Pretty huge. But on the front through the cabinet cutout were the buttons I'm familiar with on 14" drives - run, stop, fault, drive ID plug, etc. And in the front was a recess where a removable hand-held keypad unit sat. This hand held unit had like 40 or so buttons on it, almost looked like a diagnostic keypad or something. Odd. There was a nice dec rack with something in it that looked like a disk drive... HSC... something. Didn't get too close of a look. A few HP lowboy cabinets, and some 7980S tape drives. Several microfiche readers that looked in good shape. I spent a lot of time talking to the owner, and sucessfully built a rapport. I'm welcome to come back any time, and they'll let me just walk through. They also agreed to call me when stuff comes in that may be of interest so I can have a looksee before it's torn apart. The "big iron" stuff listed above they will let go very cheap. However, the RDxx drives they know get some amount of money on ebay, so those they will not let go dirt cheap. If anyone is interested in any of this, let me know. They will be moving buildings before too long and want to get rid of as much as possible so they don't have to move as much. That means their motivated to get rid of the heavy stuff cheap. I'm also curious just what that TA90Z thing was. Jay

S-100 stuff found

by waltje＠pdp11.nl

Hi gang, Just returned from a customer in Norway. While cleaning up some issues there (which included doing some *literal* cleaning up; the place's machine room had never seen a cleaning... eeeew !) I bumped into a box with "ohyeah, thats old stuff, just throw it out" kinda stuff. Obviously, I opened it up, and found a couple PDP-8 boards (DP-8 programmable timer) with manuals, and about 14 what looked to be S-100 boards. More checking and some calling last night indeed confirmed these to be S-100 boards: Cromemco 64KZ 64KB RAM board Cromemco PRI printer interface Cromemco 16FDC floppy disk controller Cromemco WDI hard disk interface unknown 32KB STATIC RAM board (qty 2) XCOMM 001785 ? serial interface board? (qty 2) XCOMM 001790 SA1000/ST506 interface (qty 2) unknown TMM416-based RAM board (64K it seems) NNC CPU-Z80-IEEE NNC CPU board (qty 4) If anyone wants there, make me an offer I cannot refuse. Yes, I can bring them to the U.S. next week, if so desired, and ship em >from there.

Macs: Billions and Billions sold

At one MacWorld I attended one vendor had taken dozens of Pluses, SE's, SE30's and Classics and built what can only be called a throne out of them, with a Lisa for an ottoman - and ran the Pyro! screensaver on them all, then photographed show-goers sitting on it and handed out the Polaroids. That took dozens of mini-Macs but perhaps you could use the few you have to do something equally silly - run the Energizer Bunny, network version. Hook 'em together with PhoneNet, install the init on them all and the "Start Wabbit" application on one, and let it rip. Bunny marches across one screen, then the next, then the next and around and around. I have the software if you want it. Sort of a deranged kinetic art form... Seth Lewin

Macs: Billions and Billions sold.

OK I'm not talking about the burger. But anybody have any creative ideas on what to do with two or three Mac Classics that I keep finding. I can't throw them out, on conscience. John A.
