> Do you have any specific model numbers for "3D graphics terminals"? I am drawing a complete blank on the product numbers (5xxx series?) but IBM made a series of CAD workstations in the mid-80's.

I didn't think they were IBM RT based. http://www.cadazz.com/cad-software-history-1980-1985.htm Is sort of interesting, too.

short haul modems

by aek＠bitsavers.org

I picked up a bunch of Black Box "Short Haul Modems" yesterday. I hadn't ever looked at such things closely before, but they are just powered RS-232 to current loop converters. Very handy for old CPUs that only have current-loop TTY interfaces, like the Varian 620, or hooking a 33 to modern gear (assuming it can talk 110 baud). I'll get the circuit traced out in the next few days, and check what current they are running through the loop.

Over the course of time, about ten of the two-port desktop units ("T-Box" 2502) and four or so of the 32-port rackmount boxes ("S-Mux" 2532) found their way to the University computer museum of Erlangen University where I work. I've heard there once were lots more of them used here for timesharing the computing center machines form terminals scattered all around the campus. We're toying with the idea of setting up a small segment of CATV cable (we still have some old Magnavox line amplifiers, splitter jacks and such), but we seem to miss a crucial piece of hardware: the bootloader box, from which the "modems" receive their firmware and channel assignments and without which they consequently won't work. We suspect it was junked together with the main stock of modems about ten years ago. I've not been able to find much about LocalNet online, so I don't know what type designation the bootloader box has, what it looks like and so on. Since it is most important for the functional demonstration network we'd like to have, I'd be very thankful for any information. Yours sincerely, -- Arno Kletzander Stud.

external sorting with 9-track tapes

by legalize＠xmission.com

Hey, I was just skimming Knuth's Art of Computer Programming chapter where he talks about external sorting. It occurred to me that doing a massive external sort would be an impressive demo for someone viewing a collection. Does anyone here own enough 9-track magtape drives to do external sorting and multi-tape merge operations? It would be cool to watch a time-lapse film of the operation! -- "The Direct3D Graphics Pipeline"-- code samples, sample chapter, FAQ: <http://www.xmission.com/~legalize/book/> Pilgrimage: Utah's annual demoparty <http://pilgrimage.scene.org>

Anyone have interest in an IBM 3363 drive? I've seen a couple on e-bay that didn't sell. I have one, with 2 PS/2 controllers, and a couple of blank media. I don't (and never have had) a functional PS/2 machine to plug it into. Status is unknown (as I have no way to test it), in original box with original manuals/driver disks/etc. What is it's value, anyone want it for reasonable value/shipping costs?

Looking for an Altair 88-DCDD Manual Scan

by eric＠rothfus.com

I have a copy of the manual on its way to me, (thanks Jack!) but in the mean-time does anyone have a PDF of the Altair 88-DCDD floppy disk manual? In particular, I'm looking for the section regarding data encoding - format of the data on the disk itself. Probably some form of FM, but with hard-sectors. I've looked everywhere, but for some reason, most Altair doc sites don't have the DCDD scan. Yup, the Altair is the next target for the SVD. (http://www.theSVD.com). Eric

punched card equipment trove

by brian＠quarterbyte.com

If you haven't seen this yet, there is an amazing lot of unit record equipment up on ebay: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=8792244955 It should go to a museum. (The Computer History Museum has all of these items already but someone else...) Heck, it IS a museum. The 2821 controller is a particularly useful if you want to hook up the 2540 card read/punch and a 1403 printer to your parallel channel mainframe :) The seller has some other mainframe gear up. All of the prices at least 5 times too high, but maybe will be negotiable after the lots close without a bid? If anyone is interested in a part of this, perhaps we could put together some group proposition. I'd be willing to discuss it anyway. Write off-list if interested Brian

That's a big and fat 1/2" 200/556bpi 7-track magtape designed for use with Honeywell computers (I have a series 16 controller for it). Pictures and information can be found on my h316 website http://h316.hachti.de --> Stuff --> Tape Drive I NEED some information and help. I want to get in touch with everybody who ever operated, maintained or even constructed such devices.

External 3.5" drive for TRS-80 4P?

by kawninja＠cableone.net

Hi all, I'd like to add a third drive, which would be an external 3.5", to my TRS-80 4P. The 4P never came with an external floppy connector like the TRS-80 Model 4, but the 4P floppy controller apparently does support four drives and some folks have successfully modified them to use external drives. Any ideas on how to do this? I'm thinking maybe just set the 3.5" drive select jumper to DS2 (there's DS0, DS1, and DS2)... connect enough straight floppy cable and connectors for everything to the internal controller jack... and see if the 4P recognizes the 3.5" drive as :3. Thanks, Steve P.

Streched bands on QIC DCs

by aek＠bitsavers.org

> (1) did the band formulation change in the early '90s to eliminate the problem? Not that I know of. I just think the useful life is limited to 10-15 years. I don't think the designers of these tapes ever thought about the need to read a tape written 20+ years in the future. > since they seem to be being dropped rapidly, and many computers won't bootstrap > off of anything else, it looks like there might be a problem in about 5 years. There has actually been serious problems with keeping the drives going as well as the pinch roller decomposes. Be VERY careful the one in your drive doesn't soften and turn to goo when you're using it. If you follow the discussions about this over the past few years, a LOT of HP software on DC100 tapes has become unrecoverable because of deterioration of the rollers and the bands fusing to the tape. The most important thing right now to get as much data preserved as can be recovered. This is why I've been trying to read as many of these tapes now as I can before the data I have becomes too expensive and time consuming to recover.

Help ID oddball SCSI controller

by SUPRDAVE＠aol.com

In a message dated 4/7/2006 11:57:47 A.M. Eastern Standard Time, dgy at dakotacom.net writes: Hi, I've got an oddball SCSI controller card that I would like help identifying (actually, I have several *different* ones but we'll start with this one :> ) Card is full length. PCI. Appears to be made by IBM (FRU 76H6875). Has three AIC-7880's on it connected to three "internal" wide SCSI-2 connectors -- and a single external connector presumably tied to one of these three busses. Onboard PowerPC and what appears to be a connector for a flying CF card. A pair of 10 pin headers one of which has a "SERIAL" legend nearby. A third header labeled JTAG (no doubt for manufacturing diagnostics). External connector appears to be LVD or SE (bummer, I was hoping to find a HVD in this box of goodies...) I'll assume it's a RAID controller. But, question is how well (if at all!) it is supported and whether it is worth my time or if I should just toss it in the box and dig out the next "mystery card"? Thanks! --don ------------------- Its probably a Serveraid 5,6 or 7 series controller. Somewhere on IBM I found a document that listed the capabilities of the controllers over the years.

downloading & installing using VMSINSTAL problems

by compoobah＠valleyimplants.com

I am trying to install some layered products on my AXP-VMS machine (VX42 Multia running v7.3-1) and I keep running into the same error. for $@sys$update:vmsinstal (product, tried with CXX065 and AXP_DECWRITE31A) dka0:[install_sets] options n it prints "error reading dka0:[install_sets] AXP_DECWRITE31A.A software block CRC error invalid block size in save set invalid record size in save set invalid record size in save set" several times and then errors out to DCL. I'm getting the sets from vmsone.com, but I do have to launder them through other machines, as Bet doesn't have internet access or a web browser. I've tried Windows at work (high-speed network access), thought it was the Windows bitrot that sometimes occurs, but the "A" saveset of DECWRITE31A doesn't even work when downloaded from a Macintosh (tried with VMSINSTAL and BACKUP). What am I doing wrong, or is it just my cheap equipment (other weirdness- when DECwindows starts it locks up the keyboard - bizarre, don't know if this is a Multia+VMS problem or an issue with the Multia+VMS+SGI keyboard. I'll have to do some testing), What's a good baseline for Alphas in terms of usability with VMS7.3+? the 233MHz LCA seems to be not much faster than a VAXstation 3100/76, and if I do find another Alpha, I don't want to spend a lot on something that creaks along (and I know what the SPEC scores say- but this VX42 is not up where other machines scoring ~100 SPECxx 92 are in basic useability)

Ultima Underworld

by julesrichardsonuk＠yahoo.co.uk

yeah yeah, it's a game and I don't normally do game posts :-) Does anyone happen to have a copy? I was watching the lad playing some 3D adventure game on the playstation 2 earlier and it brought back memories of playing Ultima back in the early 90's on my old 486 PC and just how darn good that game was. Other than the low screen res by modern standards, I reckon it should have stood the test of time pretty well. I've got a copy of the game (actually, I can't remember which of the two variants it is) on tape back in the UK, but won't be back there for a few months (plus I have no idea if the tape will still be readable) I've just installed DOSEMU / Freedos under Linux on the laptop that I have with me and it's happily playing an Ultima Underworld demo that I found on the 'net, so there's every chance the proper game would work. (I don't have sound going yet, but I don't have sound configured under Linux itself yet - I *think* DOSEMU's capable of providing soundblaster emulation for programs that it runs) cheers!

Streched bands on QIC DCs

by compoobah＠valleyimplants.com

So, forward thinking on this problem (1) did the band formulation change in the early '90s to eliminate the problem? if not, then (2) has anyone tried anything for replacement or (3) how do you keep QICs in good repair band-wise? since they seem to be being dropped rapidly, and many computers won't bootstrap off of anything else, it looks like there might be a problem in about 5 years. Fortunately, it looks like the tapes aren't creased.

Convert D1000 to LVD?

by dgy＠DakotaCom.Net

Hi, I have a D1000 array and wonder if there is any way to convert it to a LVD interface? (I have lots of LVD *PC* controllers but only one HVD and that's SBUS). Thanks! --don

Help ID oddball SCSI controller

by dgy＠DakotaCom.Net

Hi, I've got an oddball SCSI controller card that I would like help identifying (actually, I have several *different* ones but we'll start with this one :> ) Card is full length. PCI. Appears to be made by IBM (FRU 76H6875). Has three AIC-7880's on it connected to three "internal" wide SCSI-2 connectors -- and a single external connector presumably tied to one of these three busses. Onboard PowerPC and what appears to be a connector for a flying CF card. A pair of 10 pin headers one of which has a "SERIAL" legend nearby. A third header labeled JTAG (no doubt for manufacturing diagnostics). External connector appears to be LVD or SE (bummer, I was hoping to find a HVD in this box of goodies...) I'll assume it's a RAID controller. But, question is how well (if at all!) it is supported and whether it is worth my time or if I should just toss it in the box and dig out the next "mystery card"? Thanks! --don

Sticky tapes

by aek＠bitsavers.org

> I'm now wondering about streched band That is EXACTLY your problem. The tensioning belt isn't tight enough any more and as the tape rolls it goes slack. When it stops at EOT, it folds over itself, and often creases the tape, creating a bad spot that you hit on every pass. I have had to replace 100+ belts as I've been reading all of my tapes. Pretty much any tape from the mid-80's earlier will have a bad belt. Sometimes they're so bad they snap on the initial retension (you do know you have to retension the tape before you try reading it, don't you?) Scotch DC450+ carts from the early 90's have been my primary source of donor belts. The bad news is the piles of surplus carts that were all over Silicon Valley in the late 90's are pretty much all gone now..

Sticky tapes

by compoobah＠valleyimplants.com

It's not what I thought it was- looks like the tape "emulsion" is fine. The looping only seems to happen when the tape gets to the end and is ready to rewind. Listening to the tape, it sounds almost like there's some slack or slippage, but the cartridge seems tight when I look at it (take it apart, poke and prod, etc. The tapes that I'm having problems with (both trapped loops binding the tape and plain read errors) are noticeably noisier than trouble-free cartridges. I'm now wondering about streched band or lubrication issues (they have a much duller surface than newer DC600/DC6150s).

AViiON 3000

by dgy＠DakotaCom.Net

Hi, I've inherited a 3700 so my 3000 is now looking for a use :-/ I expect to get DG/UX running on the 3700 (when I have some spare time to deal with those issues). It would seem wasteful to also install that on the 3000. I figure I can fill the 3000 with drives and glue other peripherals onto it and turn it into a "media machine" (i.e. support many different types of tape, disk, etc.) and file server. Choice of OS to install on it becomes an issue. It's a quad Pentium box so ideally something that supports SMP. I would *like* to find something that can support blocksizes != 512 (for my MO drives). I'd also like to find an OS that would let me treat the multiple drives as a single *big* drive (e.g., DG/UX supports virtual drives that can span multiple physical drives) so I can set up a nice /distfiles filesystem. The box will run headless. Suggestions? --don

Programmer's conundrums

by cclist＠sydex.com

I recall that one test we'd use on new assembly language programmers on the CDC 6000 series was a routine to save the contents of all of the registers without using an exchange jump. It's much harder than it appears to be at first. No register assumptions like B1=1 allowed, either. Are there any similar tasks on other architectures that try a programmer's mettle? Cheers, Chuck

sticky tapes

by compoobah＠valleyimplants.com

I'm working to image some of the CV tapes from the CADDStation before they fade away, and I'm running into a problem with "sticky tapes". They're not losing the coating, they're just sticking to something and catching, requiring dissasembly of the tape cartridge (QIC) before they will run again. One had an extraneous loop when I popped the cover. The two that I have done this with so far imaged fine after I messed with them, but is there a way to fix this to start? I'm not even sure about the etiology. Is the "baking" from the HP tapes thread likely to help? The tapes that have a manufacturer's mark are 3M DC300-XL/P All date from about 1988.

BASIC-80 manual online anywhere?

by frustum＠pacbell.net

I have an original copy of Microsoft BASIC-80 (c) 1979, Release 5.1. It is for Heath/Zenith systems, but really that part of it is just an insert at the start of the manual. The rest of the manual is generic and applicable to all BASIC-80 versions. Before spending the time to scan it, is this online anywhere already? I did a google search on BASIC-80 manual but didn't find any hits in the first few pages. Likewise, I have an original manual for a similar vintage MS BASCOM (basic compiler). Thanks.

Replacing 80C188 and 68HC11

by kyrrin＠bluefeathertech.com

Fellow Techies, I have a device (a GPS-referenced clock) that uses an Intel N80C188-16 microprocessor, in a 68-lead PLCC package. Odd as it may sound, I suspect this chip of being defective, and I've been attempting to locate a match for it so I can prove or disprove that theory. The original part is, of course, no longer manufactured as far as I can tell. Hunting around on the 'net turned up a couple of modern equivalents, one of which is an Intel TN80C188EA20. As near as I can tell, the only difference with this chip is that it can be clocked a bit faster (20MHz instead of 16), and that it has an extended operating temperature range. There are two other possible candidates available, though not in stock at the moment. Both are made by Intel. One is the N80C188XL20, and the other is the other is the TN80C188XL20. I know just enough about these chips to be wary of differences in prefix and suffix letters. With that in mind, I have two questions for the group. (1) Of the above replacements I've mentioned, which one is most likely to be a direct plug-in replacement for the suspect chip? (2) Failing that -- Does anyone happen to have a known-good N80C188-16 that they could be convinced to part with? In this same instrument is a Motorola MC68HC11A0FNC11W in a PLCC-52 package. I need to find a viable replacement for it as well. I've had a harder time tracking down possible replacements for it. The only ones I've come across so far, that are available without an enormous minimum purchase, are the MC68HC11E0CFN2, the MC68HC11E1CFN2, and the MC68HC11E1CFN3. Once again, I'm very leery of mixing/matching suffix codes due to lack of knowledge. I do know this much: The Motorola part is operating with an external EPROM, so the chip itself is ROMless. Assistance with this mess would be much appreciated. Thanks in advance. -=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner & Head Hardware Heavy, Blue Feather Technologies -- http://www.bluefeathertech.com kyrrin (at) bluefeathertech do/t c=o=m "If Salvador Dali had owned a computer, would it have been equipped with surreal ports?"

Old apple ascii keyboard

by us21090＠yahoo.com

Hi, I'm thinking about building one of obtronix's apple 1 (ebay 8790381782), but he doesn't supply a keyboard with these latest kits (like he used to). These are the old-old ascii style. Connection to the keyboard is via a socketed 16 pin dip. The signals are 7-bit parallel with a strobe signal. Gnd and +5v are supplied to the keyboard from the Apple1. I'm told that Apple II and II+, early Franklin apple-clone systems used a compatible keyboard. The Apple 1 manual: "Any ASCII encoded keyboard, with positive data outputs, interfaces with the Apple system via a "DIP" connector." I've been looking around for a keyboard, without cannibalizing working systems (even the Franklin). Any of you have working keyboards on non-working Apple II/II+/Franklin-clone that you are willing to part with? Thank you! Scott P.S. (hmm, maybe I shouldn't have made the crack about the Franklin). --------------------------------- Talk is cheap. Use Yahoo! Messenger to make PC-to-Phone calls. Great rates starting at 1¢/min.

Tek 4041

by josef.deuschinger＠web.de

Hi Roger, I don't know, if you still have your 4041, but I have the solution for your problems. I found some DC-100 tapes, changed an ASCII keyboard, so I could type in the necessary commands and stored them on tape. It works great with a notebook and terminal program. Perhaps we can make a change, because I am looking for the programmers reference and operating manual (e.g as PDF files) as well as for the Utility ROM pack and ROM pack manuals. I would appreciate hearing from you. Best regards, Josef ------------------------------------------------------------- *Roger Goswick* ccfsm at ipa.net <mailto:cctalk%40classiccmp.org?Subject=Tek%204041&In-Reply-To=> /Wed Jul 28 12:34:54 CDT 1999/ Hi All: Does anyone have any information on the Tektronix 4041? I've got a hankering to play with the IEEE-488 bus but can't see paying the current prices that most people seem to want for a IEEE-488 controller for a P.C. I've acquired an Tek 4041 with 512-K and the rom Basic development firmware and even the manuals. But I don't have the (optional) keyboard OR the diagnostics tape. If I could find this tape then I could simple use a RS-232 terminal for program input. I've even got a nice HP 150 that could serve as a terminal, but I need that tape!! Speaking of which, this thing uses a DC100 tape. Know where a soul can find any of these tapes for less that $25.00 each? I know that GP-IB controllers are considered kind of low life - but for some reason I'm hooked on this one (could be the 68008?). Hell, you know what? I'm afraid that old computers are going to be as addicting as old analog synthesizers and Tektronix mainframe o'scopes. Thanks all.

Z80 TRAP and CP/M

by melamy＠earthlink.net

actually it was the Intel bozos. Intel released the triple supply 2708 then TI released their triple supply TMS2716. Intel released the 2716 single supply and then TI was forced to create a single supply chip and they called it the TMS2516. I don't recall TI ever making a triple 2732 by the way(probably did, bit I don't remember). TI stuck with the 25xx designations because they did not want to confuse their earlier triple 2716. best regards, Steve Thatcher >>(ref: IC Master 1982) >>Presumably chosen by Mostek to be as close as possible to the MK385x, MK387x >>F8 family numbers just to make the probability of confusing everyone as high >>as possible. > >No, *that* distinction goes to the bozos at TI with their >non-2732, 2732 (IIRC).

ComputerVision CADDstation 32

by compoobah＠valleyimplants.com

I've tied into the CV 3000-20 Model 32. Haven't replaced the cap yet, though. Does anyone know if the Sun machines have the P1&P2 terminator paddleboards with switches at either end of the VME bus (the swithches sound like some sort of bus grant adjustment from the manual). The magtapes have a dull surface to them. Does anyone know if this is normal, or will something need to be done to stabilize them before imaging? I have pictures of the boards, but no place to put them. Several people have expressed interest in seeing them. I can either hitch a ride on someone else's website, or do direct e-mail. At this point, they are big (~3.5 MB each) JPEGs that you can read chip numbers from, but they could be downsampled. Have outside front, connector side of the cardcage, and the 3004 CPU, framebuffer, GPU, GPU interface, tablet interface, and the (SCSI & 2 RS-232) cards.

I started using this a few years into the project, so the early stuff isn't this way. The <description> has been getting longer since I moved to a server that supports long filenames. And, to answer your earlier question, I don't think I saved any AED terminals. I do have the schematics, users manual, and rom source. The AED 512->1024 are a single large PCB.

Programmer's conundrums

by marvin＠rain.org

My experience indicates that anyone who is very good at what they do, regardless of the field, would qualify in your description. It is the mediocre <insert profession here> who seems to be more interested in talk than doing. Unfortunately, our society is becoming more talk rather than action oriented. Getting the job done seems to be less of a priority with new people to the workplace from everything I've heard. BUT to be able to get the job done quickly under trying circumstances does take experience and the work ethic to gain that experience, and that does leave the future in doubt. > You needed special people for that kind of work.

Tektronix 4632 Video Hard Copy Unit -- Manual? & 4631 parts

by djg＠pdp8.net

>Does anyone have a manual for this? > Yes, I can try to scan it this week. The foldout schematic pages are slow to scan so if you only need the text pages email me and I will make them available first. I bought what should have been a 4631 and is labeled a 4631 but somebody put the 4632 interface board in it. Does anybody have a parts 4631 I could get the interface board in the back from?

OT: video signal question

by bert＠brothom.nl

Hi, Appearently something like video printers exist. They have "normal" video inputs and are somehow able to extract a command to make a hardcopy from the video signal. In my case the command is triggered by a button on an edoscope control panel. Can anyone tell me how the trigger signal is embedded in the video signal? Thanks! Bert

Norsk Data Technostation

by toresbe＠ifi.uio.no

All this talk about CAD workstations here got me thinking about the Technostation. My braindump on this is that it was a ND-5xxx-processor (the 32-bit workhorse) with a ND-1x0-processor (16-bit CPU running the OS and I/O), with two gas-plasma displays emulating the standard Tandberg TDV-2215 ( http://toresbe.at.ifi.uio.no/nd-skjerm.jpeg ) terminals, and a large Sony screen displaying the graphics. Just a relatively standard ND server with the custom logic board(s), I guess. It also had a special desk, and a cursor pad. Also, by coincidence, I came across this in some old newspapers I was going through (Norwegian!) http://toresbe.at.ifi.uio.no/technostation.jpeg about a design award it won in Norway, though I guess that's useless unless you're Scandinavian or know how to translate rot13. ;) Anyone know any more about it? I guess it's a shot in the dark. An ex-ND employee told me about some West-German incentive program for high-tech businesses or something which would sponsor the purchase of a TechnoStation. Field technicians would come home almost crying after having placed the machine in moist basements and barns and places like that. :) -toresbe

Installing 3.5" drive in a TRS-80 Model 4P

by kawninja＠cableone.net

Hi all, I've got an old Teac 3.5" drive (in 5.25" mount) with jumpers set as Drive 1 that I want to install in my TRS-80 Model 4P. Tried to tackle installing it today, but was unsuccessful. Supposedly the TRS-80 Model 1, 3, and 4 machines will read / write to older 3.5" drives with jumpered drive select. The 4P's drive cable is card edge only, so tried using a PC drive cable hooking up the original 5.25 drive and 3.5 drive using both the cable's end and middle jacks. The 4P wouldn't recognize either drive in any position. Anyone know what I'm doing wrong? Maybe it's due to the wire twist found on PC floppy cables? I'm about at my wits end trying to find a way to transfer TRS-80 DSK files from PC to 4P. Thanks, David

AT&T Pixel Machine Available

by jnugen＠gmail.com

I'm moving and need to get rid of this: AT&T Pixel Machine Model: PXM 964dex Serial No.: PXM-10178-FB Date: OCT/02/89 I have the machine, the interface card to a VME-based Sun workstation, and some manuals. I was unable to locate any software, however. Here is a PDF that describes the machine: http://www.cs.yorku.ca/~amana/research/parallel.pdf Local pickup only!

Anyone have ideals for this guy?

by bob099＠centurytel.net

http://www.diycalculator.com/sp-hrrgcomp.shtml Our cunning plan is to design ? and hopefully one day build ? what we are calling the Heath Robinson Rube Goldberg (HRRB) computer. This would be a (possibly cut-down) version of our DIY Calculator <http://www.diycalculator.com/aboutdiy.shtml>. However, we don't intend to simply replicate Harry's work ? where would be the fun in that? Instead, we wish to create something even more on the "Cool Beans" side (if that's possible). What we're pondering is a beast that combines multiple technologies (relays, vacuum tubes, transistors, silicon chips, etc.). Imagine a row of glass-fronted wooden cabinets on the wall. Each is implemented in a different technology, and each contains some portion of the computer, such as the system clock, the ROM, the RAM, the ALU, the CPU's status and control logic, the CPU's addressing logic, and so forth. We will elaborate on this core concept in the following topics ? what we're trying to do here is to convey our "vision." The idea is to first come up with a specification for the functionality to be represented by each of the cabinets along with a well-defined interface into ? and out of ? each function/cabinet. This would facilitate different design teams tackling the different cabinets. Furthermore, as opposed to having the cabinets linked by bunches of cables, we were thinking of providing each cabinet with a wireless communications system (or maybe they could communicate via the building's power cables, since each cabinet will require a power supply anyway). This would (a) make things look nice and (b) allow the various cabinets to be located at arbitrary distances from each other. Note that this project could grow to such a size that we'd need a big facility to host the final machine and display it to its fullest effect (possibly a museum or an airport or ... Contact Us <http://www.diycalculator.com/about.shtml> if you have any ideas ... all suggestions will be very gratefully received).

Tektronix catalogs? Have 1982, 1985 want > 1985

by aek＠bitsavers.org

> I tried looking for other documentation on older Tektronix > products through this interface and nothing useful was found. The best way to find logic analyzer manuals is test equipment manual brokers. The DAS 9200 was not my favorite (we had moved to 16500's by then) so I haven't spent time digging for them. I have the svc docs for the 9100, which I need to get on line. A few years ago, I bought the complete set of TEK catalogs on eBay >from the late 50's forward. They're in the queue to be scanned, but it's not something that can be done quickly. Most of the material on the 4050 series is on bitsavers. I have a few other 4xxx series manuals scanned but not on line yet.

Another Panasonic HHC

by ard＠p850ug1.demon.co.uk

A couple of weeks ago I mentioned I'd bought a Panasonic RL-H1400 handheld computer with printer/cassette interface. I've now got a second one. This one also came with a printer, but also with something labelled 'EPROM Extender' This is a tray that the computer fits into one side of, and the printer into the other side. Underneath there's a PCB with 8 EPROM sockets. The plastic housing was glued together, but I've got it apart without too much damage. The PCB also contains 10 or so TTL chips (all pin-through-hole), a voltage regulator, etc. I've not worked out the details yet. One odd thing is that these EPROM sockets, while the type that take EPROMs in plastic carriers (i.e. they're not normal DIL sockets), are 28 pin, not the 24 pins ones in the HHC itself. Is this the unit that would take the SNAP development ROMs? I also have the dual-voltage (110V/240V) mains adapter (my first machine came with the 110V-only version). This thing (for all it has 2 fuses inside. in nice little holders) is a royal pain to dismantle. It's assembled with 4 system-zero tamperproof screws (designed to be impossible to remove without the right tool), down holes too small to take the right tool. I ended up drilling out the holes slightly (8mm I think), then using the system-zero driver to get the screws out. It appears (but don't blame me too much if I'm wrong) that the HHC doesn't use the NiCd pack as a shunt regulator, there's a proper regulator circuit on the logic PCB. In which case it should be safe to connect the adapter with the NiCd removed or defective. -tony

HP9000/345 SCSI Problem

by vp＠cs.drexel.edu

ard at p850ug1.demon.co.uk (Tony Duell) wrote: > I don't know if it's any help, but there's a CE manual (a boardswapper > guide) over on http://www.hpmuseum.net. [...] Indeed, this is a very good site, highly recommended for HP computer-related manuals. I did consult the CE guide you mention, but it is totally confusing and this is the one that got me in trouble in the first place. This guide gives an example of the boot screen with all the on-board peripherals. This could not be further from the truth: (a) the high speed HP-IB controller is mutually exclusive with the SCSI controller, and (b) the ordering of the items in this menu (and hence which keys to press to select various options) is wrong. Great! The former misunderstanding caused me to expect to see the SCSI controller even when the fast HP-IB controller was connected to the motherboard. In fact, all I had to do to get the SCSI controller to come to life was to unplug the fast HP-IB daugherboard from the motherboard. The second misunderstanding caused me to waste my time trying to get the machine to switch to the serial port. I did not have a VDU for this machine, and I did not want to spend time trying to find one just to switch to the the console to the serial port), so I was typing the sequence blind. Since the ordering was wrong I was not actually configuring the serial port. I was rescued by the NetBSD HP300 FAQ which gives the correct order for the probe. Anyway, back to the SCSI problem. I tried an ancient Quantum 100Mb drive (yes Mb, not Gb), and the machine passed its SCSI diagnostics but failed to detect the drive. This may well be because the drive does not contain an HPUX boot code although I am sure I did not see the drive access light come on during the search for boot devices. **vp

by aek＠bitsavers.org

It would be nice to find the TEK 4100 series documentation. Brokers tend not to have TEK display terminal manuals. They were the last gasp of stand-alone TEK graphics displays before workstations killed the whole market off. My last job before going to Apple was as the architect of AED's VME and QBus display board set, which emulated 41xx's (and had things like X running on-card).

Hi, the library of our research institute has copies from at least 1/1977 completely in the shelves (they say 1/76 but looking there, the first ones were missing). At least the three articles of the TinyAsm are there, and I could make scans of them on demand. You can find an index of Byte at http://www.devili.iki.fi/library/publication/10.en.html so if you have specific articles (limited!) you're interested in I could pdf them. I won't scan everything due to lack of time, and I won't make them publicly due to copyright concerns, but we could talk about few articles. Yes, the tiny assmebler was rather structured, a nice example how to write good assembler code. Unfortunately, the Byte articles only has a hex dump - the paperbyte book had a commented disassembly, but I lost that eventually :-( Regards Holger

11/45 RTC

by fireflyst＠earthlink.net

Have you tried this with M7800 and M787 instead of M7228? I'd say if not, try that, if yes, and if that works, then look over the DL11-W manual for some sort of compatibility issue with the 11/45. This is just speculation, but it's possible that you may have to use a M787 and disable the RTC on the DL11-W or something strange like that. > -----Original Message----- > From: cctalk-bounces at classiccmp.org > [mailto:cctalk-bounces at classiccmp.org] On Behalf Of Jay West > Sent: Monday, March 27, 2006 11:32 PM > To: General Discussion: On-Topic and Off-Topic Posts > Subject: 11/45 RTC > > Given that the system seems to pass a lot of diags, but fails > the LTC test, I'm focusing there.

Need help using cgsix in IPX

by fernande＠internet1.net

Hello All, I've got an IPX that I've started working on a while back, but sort of forgot about. I've already done the NVRAM battery, messed around with Openboot, and done a NetBSD install. I haven't done anything with it since.... I still know very little about NetBSD, or any other Unix for that matter. Any way..... I have this Sony GDM-1602 sitting here. It's max refresh rate seems to much less than what the cgsix in the IPX wants to work with. I tried specifying resolution and refresh rate in Openboot, but it still doesn't work. Assuming I can use this monitor with the IPX, I don't know enough to figure it out. If I flip the monitor off and on a few times, I can see the it's getting a signal, but the characters are sort of skewed across the screen about 3 times. Any help would be appreciated!

old HP manuals + HP Journal

by aek＠bitsavers.org

I think it is great that they want to collect the old manuals (too bad they won't scan them themselves though). -- It takes a significant amount of work to do a good job of scanning and post-processing an HP manual. Many of the schematic sheets are extended length (>17" long) I wonder what happened to all of the content they took down several years ago (things that included mid-90's test gear like the 16500C) FYI, I took a look at the 1630 manual, and it was recovered from microfiche. I should bug someone I know about getting a paper copy to scan.

Looking for a few NEC upd6145s

by ethan.dicks＠gmail.com

I'm contemplating a project using a upd6145 "SPI interfaced On-Screen Display" chip. If I have the era right, it's from about 1993, and would have been used inside TVs and VCRs to crate menu/overlay text for setting preferences. There's one on eBay right now, but I hate to do this kind of work with one chip and no spares. Also, I can't seem to find the specs on it. There is at least one project out there using it, so I could probably determine all the pins from where it fits in the circuit, but a datasheet is always handy. So... before I dig too deeply, does anyone here know of a vendor that might have 2-3 of these? I'd probably settle for a brand/model number for a sighting if anyone happens to be into TV guts. Thanks for any pointers, -ethan

Auto dealer closure uncovers...

by innfoclassics＠gmail.com

An old Auto dealership closed and I got some interesting older equipment. A Reynolds and Reynolds 1000 Z80? 8 bit computer, two floppy from about 1980. An all in one with keyboard, monitor and two early 5 1/4" floppys. 2 ADM 5 terminals, the classic early ADM all in one design. 3 Televideo 925 terminals with keyboards Reynolds and Reynolds 2000 tower server (Multibus 1) No HD This is actually a NCR 4350 7102. Original IBM XT286 wi original box, no HD Original IBM CGA Color Monitor wi original box and packing. TI 820 Dot Matrix printer in its box. A real classic workhorse. 2 LA 120 Decwriter III printers. Why oh why do I want these. Will part out or ship whole. Nice IBM 2390 Plus 24 pin dot matrix printer. A old Cosmowriter 4000 daisywheel printer with both parallel and serial interfaces A bunch of RJ45 serial cable kits. And a OT Mac G3 300 small tower, Sony Monitor and no Hard drive. I think I am going to try to get this to work. I have a spare HD but no OS. I understand it will run OSX but slowly. They kept all the hard drives rather than let me erase them. They even stripped the Reynolds and Reynolds 1000 down trying to find a HD, not realizing it is just a two floppy 8 bit computer. I had to put the housings back on to get it in the van.+ The NCR 3450 tower is very heavy and awkward and I am inclined to strip it down unless someone objects. If anyone on the list is interested in anything let me know. Please contact me off list or at whoagiii at gmail.com. I thought I would mention it to the list first before it hits eBay. I am a good packer. They had lots of space so anything they discontinued use to got sent to the basement. I remember early Data General systems running in Auto Parts stores also. This is one of the reasons I check the old users when they close down. Unfortunately much of the equipment is quite dirty. -- Paxton Hoag Astoria, OR USA
