Have to concur with this. Even the "minimalist" (i.e. non-GNOME/KDE) *nix "desktop environment" projects these days are getting so bloated that I've given up bothering with them and set up an X environment one component at a time. Currently running Window Maker with SpaceFM and ROXTerm; getting it all properly set up and tweaked to my liking took some doing, but the payoff was well worth it. Now if I could only excise the GTK3 blight entirely, I'd really be set.

There was a recent discussion about code density (I forget whether here, or on TUHS), and someone mentioned this paper: http://web.eece.maine.edu/~vweaver/papers/iccd09/iccd09_density.pdf which shows that for a combo of benchmarks, the PDP-11 had the densest code out of all the ones they looked at. (They didn't look at the PDP-8, but I suspect that since it's a single-address design, it's almost ceertainly not as dense.) The PDP-11 dates back to the days of core (it went through several generations before DRAM arrived - e.g. the -11/70 originally shipped with core), and given core prices, minimizing code size was pretty important - hence the results above. So if you want to get the most bang out of 16K buck... Not the simplest machine to implement, mind - the -8 is a lot simpler. Which axis is the most important to you? Noel

There's also the Afterstep/Window Maker crowd, open-source reimplementations of the NEXTSTEP desktop environment, which predates even Windows 3.x. Win95 was certainly very influential in the design and refinement of many other desktop environments going forward, but it's not the be-all and end-all of anything. >> Liam Proven wrote: > > How many graphical Unix desktops are sold or distributed in the world > today that are not Linux?

But this is kind of a questionable standard to begin with, because the whole point in the Freenix world is choice. No distributions offer those as default options during the install process, but all of them (aside from CDE, which only just went open-source a couple years ago and is still in the process of being cleaned up and forward-ported to modern *nixen) are available in the repositories for most major distributions, and all of them are still actively updated. > BeOS used the Windows model. Kinda-sorta-not-really. BeOS (like just about everything post-1995) takes cues from Win95, but its roots are in classic Mac OS and it definitely hews closer to that in most respects, despite the absence of a global menu bar. > Outside of Apple, I think it is fair to say that no new OS or desktop > environment since 1995 has used anything other than the Win95 model.

This "aside from the things that don't match up with my argument, my argument is flawless!" line of reasoning is novel.

I mostly use rio (based on the same named windowing system on Plan 9) for my window manager so at least I get to avoid the dancing frogs.

It was only a processor card. > Eric, I'm going to stand by my assertion that the Softcard was a single-board computer on the technicality that it did have its own RAM - you apparently forget that registers are a form of RAM - HA! They're memory, they're addressed over a bus (that just happens to be within the microprocessor), and you can directly access any register at any time (random access). As for I/O, that's what the Apple ][ bus was for, right? As Opus from Bloom County, among other comic characters, was known to utter, "PBBBBBBTTTTTT!!! ? Microsoft did offer a RAM expansion board specifically to allow the Softcard to access 64K of RAM dedicated to CP/M, and the Premium Softcard //e provided on-board RAM to CP/M for the Apple //e, as you noted. All models of the Softcard could output 80 x 24 text, not only through third-party cards, but Apple's own 64K RAM and 80 x 24 video combo card, which was often offered in packages, especially through dealers that supported business customers (that's how my system came delivered). The "etc." I mentioned was the functionality provided through the glueware logic on the Softcard that enabled RAM and 80 x 24 text output, as well as other I/O over the Apple ][ slots bus. When I was in the Navy, our ship called at HMS Tamar in Hong Kong, and I followed verbal directions (26 stops on the then-new subway under the harbor into the New Territories) to the basement level of a shopping center. There, I found clones of everything from Apple ][s and //es to every expansion board and peripheral available in the early 1980s, including both the original Softcard and the Premium Softcard //e. Everything came complete with the floppy disks and every page of the documentation, not just photocopied, but professionally typeset and offset-printed. In your missing-the-forest-for-the-trees response, you completely missed the point of my post - that the Softcard was an extremely important early product for Microsoft, the critical connection between the Softcard and the QDOS prototype for x86 MS/PC-DOS, through Seattle Computer Products, and that the number of CP/M licenses was much larger on Apple computers than S-100 systems. For those that cited the Amstrad systems, I was referring to the S-100 and Softcard timeframe. CP/M was only provided with the Amstrad CPC664 and 6128 floppy-disk based models, and the DDI-1 disk expansion unit for the 464 (only CP/M 2.2 with the 664, and 2.2 and 3.1 with the 6128). The Amstrads came along four years after the Softcard was introduced, and three years after the release of the IBM PC. By that time, Digital Research's influence had faded into insignificance, despite the full release of CP/M-86 within six months of the IBM PC's debut (albeit at six times the price of MS/PC-DOS). I do know that CP/M was used in European banking systems well into the late 1990s, mostly because it wasn't broken and didn't need to be "fixed". It probably would have remained in use well past 1999 if it weren't for Y2K's impetus for massive upgrades to current technology for 2000 and beyond.

PDP8A Power Distribution Board

by marco＠familie-rauhut.eu

Hello alltogether, i am restoring a PDP8A at the moment. The machine got a problem in the Powersupply. I think one of the emergency ciruits trigger a shutdown of PSU. In tracing this isue i hab two questions. My 8A`s manufacturing year is 1977. It`s model is 8A620. On Bitsavers i found a matching shematic for the BA8C Power distribution Board from 1976 (File: EK-8A002-MM-002_PDP-8A_Miniprocessor_Users_Manual_Dec76.pdf page 597). The Board Number is 5412000-0-1. My first question is if somone has the Board Layout with it's component locations? My second question is about the DEC4011 Chips. As i inspected the Board i found the DEC4011 Chips. First i think they are the standard CMOS 4011 quad two-input NAND`s. In the shematic it look more like a four Transistor array. Did anyone know somthing aput these Chips? Are there any equivalent parts? Have anyone a Datasheet of it? Marco

Selling keyboards without the terminal

by jnc＠mercury.lcs.mit.edu

> From: Al Kossow > The quality of modern keycaps is poor. > These guys are after mechanical boards with double-shot keytops. There's something I'm still not quite grasping. I can see two reasons for people liking the old keyboards: - i) Higher quality construction - ii) Connection, through a historial artifact, to an earlier age Am I missing any? I can definitely see the first (I myself find many modern keyboards to be complete crap), but if that's _all_ it is, I'd think there'd be a market for modern production of quality keyboards - not a large market, true, but I'd think it would be large enough to be worth servicing? (Unless the cost to produce such would be so high that there wouldn't be any buyers - but that seems at odd with some of the prices being mentioned.) So maybe people _only_ want keyboards that have both i) and ii)? Noel

Selling keyboards without the terminal

> From: Doc Shipley > You guys want people to stop scavenging those irreplaceable treasures? > Ante up, pure and simple. That works for keeping stuff out of the hands of scrappers (who are, after all, business-people) - but not for fetishists who will pay totally mind-blowing sums for them. Sorry, I'm not paying $5K for _any_ keyboard. You can buy (for example) a complete PDP-11/70 for that much money. > In the end, that system is worth twice as much as desoldered parts as > the best offer I got. But will _all_ of the constituent parts sell, or just some of them - the rest being destined to sit on a shelf, un-sold, until they are pitched? There's a similar debate in other areas of collection - e.g. antique Japanese woodblock-printed books. One can usually make more money by taking them apart, and selling them a page at a time, as opposed to selling them as complete books. (At least all the pages do tend to sell.) Some people consider this vandalism - destroying a 200-year old artifact to maximize $$. I can't say they're wrong... Noel

FYI: From: Lars Brinkhoff Date: Fri, 19 Oct 2018 11:08:29 +0000 I have Alan Snyder's C compiler running in case anyone would like to play with it. It's from around 1975, so the syntax is yummily archaic. The primary host is a PDP-10 running ITS, but there may also be machine descriptions for Honeywell 6000 series and PDP-11. At some point it seems like this compiler was tangled with Stephen Johnson's PCC.

Working with Old Tapes

by technoid6502＠gmail.com

Probably preaching to the choir, but if you are going to be mounting an old tape, there are some issues to be aware of. Tape is really stable over time and your data is likely still there. As tapes age, the surface of the gluey oxide coating degrades. The symptoms will be very discernable with a nine-track drive as you can see the head/tape interface easily. The surface of the tape in contact with the drive's head will ablate, leaving gunk on the head. The tape will make a squeaking noise while running and may eventually stop moving due to sticktion at the head. Cleaning the head from time to time may get you through a read of a tape for backup purposes, but there is a machine called a 'tape cleaner' which is a drive which leads the tape through a path seeded with knife-edges. As the tape travels through the machine, the knife edges scrape a layer of oxide coating from the tape and smooths and polishes the surface exposed. This will restore a tape to full usability and should not affect data stored on the tape. Pinch rollers can also collect oxide and need cleaning. Pinch rollers on old drives may be so degraded as to make the drive unusable. I had a Data General cart drive using Qic 300? tapes. The drive roller was wrecked. I found in my junkpile a roller from an Epson Actionprinter 3250, removed it from the printer's output roller and after cleaning the drive axle in the qic drive, used some windex to lubricate a ballpoint pen barrel, stretched the roller onto the pen body, held the body to the face of the drive axel and pushed the roller on. It worked beautifully from then on. Stone knives and bearskins. You can carefully make a set of knife edges on a board, thread the tape through the edges, and use the drive you have to move the tape through your homemade cleaner. Best, Jeff

All, I received this request from Matthew who isn't subscribed to either the TUHS or cctalk lists. He knows how to read the lists archives. Many thanks for any help you can provide. Cheers, Warren ----- Forwarded message from Matthew Whitehead ----- Date: Mon, 15 Oct 2018 08:25:39 -0400 From: Matthew Whitehead Subject: Ultrix Tape Blocks Warren, I wonder if you can give me a referral. I want to install Ultrix-32 on my MicroVAX II using the ancient TK-50 tape drive. I know the tape files are on your archive, but I need to know the block size for each of the many files; it can vary a lot. Who might be able to help me with this?

RT-11 DY install

Right, the hardware only has 18 bits of 'buffer address' (in both UNIBUS and QBUS versions). But one can still plug one into a QBUS system with more than 256KB, and use it - you just can't use memory above 256KB for transfers to/from the RX02, since it cannot physically create those addresses. If sounds from Jerry's description as if SIMH refuses to emulate an RX02 if the emulated system is configured with more than 256KB - which would be a bug, if so. Noel

Josh - You may want to contact Denis Kohlhagen, at Butler Winding. IF this is for the preservation of an HP terminal in the museum, they may wish to assist in rebuild/rewinding that flyback. There are US firms that can perform this work, and publicity of preserving history is desired by some corporate marketing dept.

Wanted: tech docs on original Iomega 8-inch full height 10MB Bernoulli drive (Alpha-10)

by spacewar＠gmail.com

Does anyone have the user, technical and/or service manual for the original 10MB Iomega Bernoulli drives? Bitsavers has the manuals for the later half-height 10.0/10.5 MB "Alpha-10H", but I'm looking for docs for the original model, which was full-height with a SASI (pre-SCSI) interface. I have the drives, about 20 cartridges that I want to image, and some additional scratch cartridges. I've never used Bernoulli drives before. These drives and cartridges were last used around 1986. I'll disconnect and test the power supply before powering up the actual drives, but is there anything else I should be concerned with? Does anyone have known-working 8-inch Bernoulli drives?

Maybe head cleaning is what is troubling the others - but I have no idea how I'd jam a cotton swab in there and find the heads to attempt a cleaning. I have a Bernoulli card in a PC that will lift the bits from DOS-formatted cartridges, and I hook the drive up to an old Mac with a SCSI card in it to image other arbitrary types (I've seen them used as audio recording devices as well as external storage for HP equipment). - David

Apple IIe addendum

by drlegendre＠gmail.com

Folks, Yay, I was wrong! The IC seems to be OK, the issue was a stuck-on kb switch. A quirk of the Apple design causes the last-pressed key to repeat continuously if any key is being held 'on'. That leaves me needing two kb switches and possibly one 'tilde' key. This is the beige IIe kb with small black print. Thanks for the space, Bill

TeleVideo Systems stuff

by pat＠vax11.net

After VCFMW this year, I've been looking at old projects I have and was wondering if anyone has any leads on TeleVideo systems. I'm looking for TS-800 terminals/systems, and interested in probably any 1980s Televideo terminals, depending on price, especially the 950, and 965s... and keyboards for them. I'd also like to find a TPC-II (the 8088-based portable computer). I used to have one growing up, and there's a bit of nostalgia there. It seems like there's more Televideo stuff lately than I remember being on eBay before, but it's all fairly expensive, especially the computers. I have picked up a few affordable things (970 & 965 terminals missing some keyboards and a TS-803 that I'm still waiting on). I have a couple of TS-801's, TS-806C and a TS-816 that are in various states of repair, that I've been poking at. I also have various Qbus era DEC stuff that I could probably trade for it. Any leads would be appreciated! Thanks, Pat

Altos 386/1000 boot/diags images?

by gordon+cctalk＠drogon.net

Long shot, but you never know... I recently obtained an Altos 386/1000 system (80386 + 4GB RAM in a tower case with tape drive and floppy) After a quick clean and check it powered up, gave a whinge about a flat battery (which I'm told is to be expected), and then booted SysV r3 Unix OK. After an hour or so poking about, I shut it down then powered it up again a short time later... Now, it starts up, does the power on checks (including the battery whinge), loads Unix, prints some information about memory and a 16 user license then stops. No more messages, no keyboard input, nothing. So I'm a bit stuck. I've found some manuals online but they're not really helping - I'll take it to bits later and see if I can read the internal SCSI drive on another system but I'm not convinced there is an issue with the drive though. So wondering if anyone knows of any installation (or diagnostic) images for these machines? It has a SCSI tape drive and I have some tapes for it, so with some SCSI shenanigans I'm fairly sure I can write a boot tape on a Linux system, or maybe even the floppy - but I need the images... Any clues? Thanks, Gordon

WTB: BPK-72 or Bubble Memory Dummy Module + Seed Module

by saburwulf＠gmail.com

Currently working on restoring some bubble memories and I'm looking for some modules originally included in Intel's BPK-72 development kit, specifically the Dummy Load module and the Seed module. http://archive.computerhistory.org/resources/still-image/Intel/intel.dummy_… These are used for testing a bubble memory system as well as repairing bubble modules which have had some sort of failure which requires manually re-seeding them. I have all the parts I need to work with the modules, I'm just missing these parts. The manual shows the schematics, component values, and layouts of both of these modules, so I can fabricate them myself if need be, but wanted to see if anyone had them handy first. Thank you again!

Anyone know where uPD2167 SRAMs appeared?

by ethan.dicks＠gmail.com

Hi, All, I asked a version of this question earlier this year. I have not been able to find any vintage machines that used these 16Kx1 55ns SRAMs. Anyone recognize them? Lots of them for sale on eBay. Probably few buyers. One would want to know which systems used them, thus my question. They probably would have been excellent in a DEC MOS memory board but I have no evidence they were used thusly. Contemporary DRAMs were cheap and 64Kx1 so that's what was in consumer gear. Anyone? Fast SRAM? Anywhere? There's little point in wiring 8 of them up into a byte vs using a 62256 except for speed. 55ns is faster than any 8MHz machine really needs (100ns-150ns was typical for those depending on bus architecture). I could see these being cache RAM for a minicomputer vs primary RAM. -ethan

WTB: BA11-K Rack Rails

by jnc＠mercury.lcs.mit.edu

> From: Paul Anderson > I don't remember the D tilting. http://gunkies.org/wiki/File:BA11-DSide.jpg This is very similar to the slides on the BA11 (-11/20), which also had the rotation, so I suspect they were all this way (i.e. there no early versions without, etc). Having said that, if anyone has a -D with something else, please send me an image so I can document it. > From: systems_glitch > I'd prefer a set of original outer rails, but something newer or > something I have to modify a little would be fine. Probably the easiest option is to buy a set of those C-230-S's; the mounting holes on their inners match the locations of the swage nuts on the BA11-K sides, so it's straight simple bolt-in. You'll lose the rotations option, though. Noel

> From: Bill Degnan > What is the part number for the -D ? Do you have the inners? The only -D inners I know of are the kind shown here: http://gunkies.org/wiki/BA11-D_Mounting_Box and if you have those, you're in luck; the outers from a still-available Chassis Track unit are perfect replacements for the original outers. Kinda pricy, mind, but at least they're available. If you have a different inner, I'd love an image, so I can see what it is, and document it. If you have no inners, kinda ugly. You can buy that CT unit, but you'll have to drill matching holes in the inner - and you lose the rotational capability. Noel

> From: systems_glitch > I do have the inner rails/latch system for tilting the box, they are > plain aluminum. Like the lower picture: http://gunkies.org/wiki/BA11-K_mounting_box there? I'm guessing that's zinc-plated steel. Alas, I don't know who made those (may have been DEC themselves), or a source for them. _But_.... I have some Chassis Trak outers which are almost compatible. (I say 'outers', but actually many slide sets are 3-part; there's an outer which bolts to the rack, an inner which bolts to the mounting box. and then a third piece, a 'middle' I guess we can call them. Sometimes the middle and outer can be separated, with a safety latch you have to release - but I think I recall seeing one set where you can't extract the middle mrom the outer - at least not out the front.) Anyway, the silver inners do fit into the track in the middles of those CT units - all except the two wheels at the inside end of the inners! Too bad, because I have no use for these outers, and would be happy to hand them over to you. The other possibilithy is that I _might_ have a spare set of the silver outers. I have 2 sets of the outers (2 left, 2 right), 4 of the special pivot bolts - but only one set of inners - at least that I can quickly find. Let me have a look around, and see if I'm really missing the inners - if so. I might be up for trading you a set of outers for something I can use. Noel

The -K has the power supply on the end, the -D down one side. What slide hardware, if any, do you already have?

I used to have a SCSI interface version of that drive type, I made backups of my Mac Plus (I think it was) hard drive. Since I don't have it currently, I believe I gave it to a friend along with the rest of my Mac Plus peripherals. I don't recall the capacity of my specific drive, but it used a "data cassette", which had a notch in the tape case to prevent use of regular cassette tapes.

CPT boards

by jules.richardson99＠gmail.com

I borrowed a pile of scrap 1970s-era PCBs from my local recycler yesterday, just to make sure there was nothing important among them before they go off for processing. Among them are six boards branded as CPT, which I assume (as I'm in MN) is the CPT Corporation that was in Minneapolis. The double-sided boards are organized in five rows of five ICs, with 44-way edge connectors and IC date codes in the 1973-1977 range. I seem to have p/n's 910012, 910014, 910015, 910017, 910018 and 910022. In addition to this there's a smaller board which references "deck 1 heads" and "deck 2 heads", and appears to have a p/n of 910025. Does this ring any bells with anyone? The Wikipedia entry for CPT mentions the 'VM' machine in 1976 with dual tape units, so I wonder if they're from one of those... if so, I'm curious if there are any surviving intact examples out there (or other info, there doesn't appear to be any CPT stuff on bitsavers) cheers Jules

Ethernet names...

I was there and it was always called "The Ethernet". When the 10 Mb standard came into being, it was then referred to as "The Experimental Ethernet".

Digico computer

by cc＠informatik.uni-stuttgart.de

We recently got a Digico Micro 16V computer including a Pertec 3342 disk drive. It is a 16 bit minicomputer based on 74181 ALUs and a couple of 4k core memory modules. Since the condition of the system is not the best (dirt, dust, some bent wirewrap pins), I'm looking for the usual information :-)) - technical manual, schematics - software I'm thankful for any information.

Ethernet names...

It's quite possible that in Metcalfe's interview (which is what the WWSUL account seems to be pretty much wholly based on), N years after it all happened, his memory flaked and he got the sequence wrong. I've had the same thing happen to me, trying to recall the sequence/timing of early IP work at MIT. I was sure X happened before Y, and then Jerry Saltzer dug up an old progress report... There's a reason that the gold standard for historians is contemporary documentation. Along those lines, here: http://www.chiappa.net/~jnc/nontech/tmlotus.html is an amusing story of my encounters with this effect on some Lotus Indycar research I did. Noel

Ethernet names...

Does anybody know names / terms that correspond to the original 3 Mbps Ethernet? I.e. 10 Mbps Ethernet is also knows as Ethernet II (2) and D.I.X. (for Digital, Intel, and Xerox). Was the first 3 Mbps Ethernet simply called "Ethernet" with an implicit "I" (1)? Was there a name to differentiate it from D.I.X.? Grant. . . . unix || die

PDP-15 documentation

by mattislind＠gmail.com

I have now finally concluded the PDP-15 documentation scanning project. Many year ago my father saved a big lot of PDP-15 documentation that was thrown out from Philips in Stockholm. I have over the years scanned documents on request which has ended up at bitsavers. Some docuements were already present on bitsavers. Now I took a stab and finalised this project. All the remaining PDP-15 has now been scanned and I put them here: http://www.datormuseum.se/documentation-software/pdp-15-documentation Many documents already has made its way to bitsavers but many remains. There are DOS-15, XVM/DOS and various general documents such as operators guide, course handouts etc. The only remaining document to scan is the RSX PLUS III reference manual which will be tricky to scan without damage it. Happy reading!

Source code listings from REDAC PDP-based PCB layout system.

by mattislind＠gmail.com

I have a set of around 5 to 8 binders with printed source code listings >from a PDP-15 system. The listings appear to be from a REDAC SOFTWARE LIMITED PCB CAD system. The name of the software seems to be REDAL 3 MARK 7. There are dates on the listings in the range 74 and 75. https://i.imgur.com/m1ji9uR.jpg https://i.imgur.com/SzaiH78.jpg First of all does anyone has more info on the REDAL software from REDAC? Then secondly is there anyone interested in these binders with listings? I think the quality of printout is good enough to do OCR on. Note that there is no guarantee that these are the complete set of binders with listings. /Mattis

Rack-mount or tabletop version of DEC RX50 floppy drive?

by spacewar＠gmail.com

Did DEC offer a rack-mount or tabletop box version of the RX50 floppy drive, as they did with e.g. the TU58 and TK50 tape drives? I'm wondering how they expected the RX50 drive to be packaged when used with a Unibus PDP-11 via the RUX50 controller.

Ethernet names...

by w9gb＠icloud.com

Grant - Occasional vague references to ?I?, when Ethernet II was used (as I remember). I assumed the reference was for initial 3 Mbps work at PARC. Gateway Communications started in Irvine, CA (1981?) offering G/Net (~double the 3 Mbps), I remember installing their demonstration system (1982 or 1983?) By 1983, 3Com ThinNet (10-Base-2) released for IBM PCs. University of Iowa graduate college installed one of their first LANs with an Altos sever (8086, 10 MHz). greg == From: Grant Taylor <cctalk at gtaylor.tnetconsulting.net> Subject: Ethernet names...

Ethernet names...

by jnc＠mercury.lcs.mit.edu

> From: Eric Smith > 3 Mbps was sometimes referred to as experimental Ethernet, but AFAIK > the only official name was "Ethernet". > The best way to refer to it is probably "3 Mbps Ethernet". I was trying to remember what we called it at MIT (which had one), but my memory was hazy, so I want back and looked at the sources for the packet switch I wrote (which supported the first Ethernet, before the 10Mbit version even came out), and I found (slightly to my suprise) that it was "3Mbit Experimental Ethernet", or just plain "Exerimental Ethernet". (Of course, that was just MIT - other sites may have had different terminology.) No doubt we renamed it once the 10Mbit version showed up - I can probably search for early versions of the code to confirm this, if anyone cares. Anyway, I'd vote for the latter, short name. > From: Bill Degnan > See where wizards stay up lote by Katie Halner and matthew lyon. Interesting! It looks (from the Notes) like this was gleaned from an interview with Metcalfe, and she was _very_ careful (I helped her with the technical details - you can find me in the Acks), so I'd tend to believe it. My _guess_ is that was his early, 'in his head' name for the thing, and when they set out to actually build it, it was re-named 'Ethernet' (as Al's memo search seems to indicate). Noel

Looking for HP 1000 A990 backplane jumper board and memory frontplane

by glen.slick＠gmail.com

I have an HP 1000 A900 20-slot box with a working 4 card CPU set (sequencer, data path, cache control, memory controller). I also have a 12990-60102 A990 CPU card that would replace the 4 A900 CPU cards and install in place of the A900 memory controller card. What I don't have is the 12990-60020 jumper board that would install in the A900 backplane instead of the A900 sequencer, data path, and cache control cards, nor a 12230-60001, 12230-60002, 12230-60003, or 12230-60004 memory frontplane to connect the A990 CPU to one or more memory array cards. I'm not very hopeful, but is there any chance anyone on the list happens to have a spare HP 1000 A990 12990-60020 jumper board, and/or a 12230-60001, 12230-60002, 12230-60003, or 12230-60004 memory frontplane that they would be willing to part with? Not expecting these for free. These might be parts that 360 Technologies had before they recently closed up shop, although if they did they probably expected business critical prices for them. (For reference, the HP Museum site has a copy of the HP 1000 A990 Upgrade (HP 12990C) Installation and Service Manual, 12990-90011).

PDP-11 in russia?

by jwest＠classiccmp.org

Someone has contacted me about a pdp-11 that controls a "measuring machine dea epsilon". It appears that they want to replace the pdp-11 with a "ibm" (I'm guessing a pc), and then they would give the pdp-11 as a gift. That is all the info I have. Are there any listmembers in Russia who would be able to take on a project? J

6809 Monitor

by guykd＠optusnet.com.au

At 12:24 PM 2/10/2018 -0700, you wrote: >Does anyone have source to a 6809 monitor program? > >I'm looking for something I can make work in a CoCo. > >Functionality I'm looking for is something that will let me read and >write to memory. Attached is the zipped C source code for a 6809 monitor I wrote in the early 1990s. Compiler used was HiTech C. Build files included. It worked, but of course 'there may be bugs.' :) It's fairly generic, so not many changes needed for other CPUs. I also did an 80C196 ver. If the zip file attachment fails, it's online here: http://everist.org/texts/6809_Mon_V2.zip Doco from the MONITOR.C file: /* File: MONITOR.C For machine: Dual 6809 game board. Compiler: Hitech 6809 C. Written: Guy Dunphy, 4/9/94, derived from an earlier version. (by me) This file contains all code for a versatile serial monitor. It is event driven, and time sliced, so it can operate in the background with other CPU tasks. All data is stored big-endian. All serial I/O is via the functions aux_get_ch(), aux_put_ch(). Serial Tx is polled, while Rx can be either polled, or buffered interrupt driven with hardware handshaking (via RTS). See monitor_init(). This monitor can be used in multi CPU systems, where only one CPU has a serial comms interface, and each has different IO/mem maps and codespaces. If there is a means for passing strings between the CPUs, then the one with serial IO is used to run a 'master' copy of the monitor, and the other CPU(s) runs a 'slave' monitor version. The master CPU does all command line entry/edit operations, and can be set to pass complete command lines on to other CPU(s). It also will echo text returned from the slave CPU(s) to the serial interface. To use this file:- * For single CPU operation, just compile it as is. * As a 'master' (talks to a slave), predefine symbol MON_MASTER. * As a 'slave', predefine symbol MON_SLAVE. Monitor commands (See also mon_help_text[] ) ---------------- Multiple cmds allowed on a line, use ';' to separate. Upper/lower case of commands and parameters is not significant. A 'range' may be:- start start end start length (Shorthand form: if length is small and < start.) start L length space (as 1st char) Repeat last command. Execute or re-edit. tab (as 1st char) Repeat 'saved' command. Execute or re-edit. tab (not 1st char) Copy cmd to 'save' buffer. esc (as 1st char) Allow re-edit of following 'repeat' cmd. (... twice ) Kill 'pass cmds to slave' mode. D range Dump mem. D (no other chars) Dump another 64 bytes F[W][I] range data Fill memory. W=word, I=increment. G addr Go (call) to addr M start [data]... Modify mem. data ::= hex_byte | string | char string ::= "text" char ::= 'c R [reg_name = value] Optionally modify register(s), then display all regs. reg_name ::= cc a b d dp x y u pc Z [flag_val] Zot! Set operation mode. Bit flags set are:- b0 Halt system (no return from monitor). b1 Inhibit serial echo. b2 Inhibit serial prompt output. b3 Inhibit all monitor output (incl help). b4 Pass all cmds to slave CPU. ESC,ESC to exit. Examples:- Z Re-initialize monitor. Lose trailing cmds. Z 0 Restore normal operation, continue. Z F Just accept commands, no system, echo, etc. Z 2 Normal, but no echo (ie half duplex). S1ccaaaadddddd....ddss<CR> Motorola data record. Load to memory. Each hex line is treated as a command, so there is no special 'load' cmd. Before sending hex, best to do a Z6 or Z7 to stop all other time consuming tasks. When finished, do a Z 0 to restore normal ops. An ASCII ACK ($06) is sent when line processing is complete and no error found. This can be used as an acknowledge. If an error is found, a '?' is returned. See s19_decode(). S0.... and S9.... Header and end records: ignored.

pdp-11/34 extravaganza

by jwest＠classiccmp.org

I was contacted about an 11/34 system available. It appears to be not just a system, nor just a system in a rack, but pretty much a full installation and all the trimmings (printers, terminals, documentation, media, etc.). I am pretty sure some of the terminals will invoke interest at the very least ;) Note - the person who has it is looking for a sale. No prices have been discussed, but my impression is they aren't going to let it all go for $50 :) The stuff is located in the Detroit metro area. I am not (nor do I want to be) involved in this transaction in any way. I'm just passing it on. I would prefer to pass it to someone who has a demonstrated ability (and resources) for rescues of this size and type of equipment. All I care about is that the equipment is rescued and by a responsible party. Do not email me expressing interest in just one or two items. I will pass it all to one person - if THEY want to part it out *after the deal* that's fine. I do have a single picture I can forward. If interested email me directly..

Computer books and PC parts clearance

by dave＠mitton.com

On this list, about 2.5 years ago, I offered up a bunch of misc computer books, PC parts, and software, for the cost of shipping, but then I got occupied with some other parts of life, and didn't follow through with those that responded. I still have the emails and will let those that answered before get first dibs. I will follow up with them in a day or so, if their emails still work. But I have added more stuff to the list, including some misc hardware bits. The current list is on http://dave.mitton.com/computer_clearance.html I will give priority to the first, but if you don't come through with pickup or shipping costs, they will go to the next in line. I am hoping to move this stuff out in the next few months. Thanks for your patience, hope some of this is useful. Dave. Sent from Mail for Windows 10

I have two of them (long in storage in the house, but they ran when I pulled them from their Unitote/Regitel rack a couple of *decades* ago. There is an RDOS - disk images, available at: http://simh.trailing-edge.com/software.html (Top entry in the list) It is about a 2.5MB disk image. I suggest that you might download SimH and that image, configure SimH as a straight Nova (rather than a /3 or /4) and see if it runs that image OK. If so, there you go! Beyond that, I *might* be able to help, but it will depend on what the status of copyright is on what I have, and whether your system can even run what I do have. I am looking into the copyright part of it - that may take a week or two. (This is something I needed to to anyway). In the meantime: Do you have a way to *write* a tape image? I have an AWS format image of an RDOS starter system. Note, however, that the label on the RDOS starter image I have suggests it may only be appropriate for a NOVA 3 or NOVA 4, so it might not run on your system. So, I'd have to take some time to boot it and try and set up a system for a straight Nova. As this would take several hours, I'm not keen on doing that unless you know that one from SimH will not work for you. I also have some OS and compiler DG floppy images, if you have a DG-compatible floppy setup. Several different operating systems there. Same issue: one would have to see how many are compatible with a straight Nova. I have images of the floppies. Diagnostics for DG systems are notoriously difficult to find. I have a few, in listing format. JRJ

What platform can run m68k COFF binaries?

by ethan.dicks＠gmail.com

Hi, All, I have a backup of some old code that I thought came from a Sun3 machine, and indeed, there _are_ binaries on there, in a directory 'sun' that _do_ run on a Sun3, verified under emulation with "tme". The part that puzzles me is the collection of object files and binaries in the directory above that. 'file' tells me that they are "m68k COFF" files. From what I've read so far, COFF binaries are from System V Release 2-4. What I can't reconcile is what they might have been compiled on. Is it possible these were made for A/UX? The relevant file dates (late-1988 through mid-1989) do overlap availability of A/UX version 1. If these are for A/UX, it would be handy to verify this, then it would be more handy to be able to run them (I have source for some of this but I'm having problems getting modern C compilers to digest 30-year-old crufty code, and for a couple of the utilities I need, there is no source). I'm reading of a "shoebill" emulator. Anyone have any experience with it? Additionally, I'm reading that FreeBSD has a binary compatibility layer for COFF but I wonder if that's for Intel binaries only or if it extends to m68k. I have a lot of experience with UNIX but my thinnest amount is in the m68k arena (mostly some dabbling on Sun3 workstations and a Perkin-Elmer 7350). Thanks for any pointers or tips. -ethan

Vice News September 25th 2018

by alan＠alanlee.org

(cross-posed to cctalk, vcf-midatlantic, and AHCS lists) Imagine my surprise when I was catching up on my daily Vice News diet today - watching today's and yesterday's episodes - when VCF Mid-Atlantics's own Corey Cohen, InfoAge, and a VCFed banner popped up! They did a story on an auction house and verification of an original Apple 1 board up for sale. They called on Corey and his expertise to verify the condition of the board! Way to go Corey! If you want to check out the segment, I've hosted it here: https://www.atlhcs.org/links/Vice_Apple_Auction.ts Enjoy! -Alan H.

More CRAY, ETC

by useddec＠gmail.com

I sorted about 15 or so more of CRAY and other supercomputer items today. Among other things were a bunch ACM Transactions on Mathematical Software and a ton of Parallel Computing booklets. There were probably 20 or more full CRAY folders. Also 6 or so CRAY "gifts", like a key fob, a semi circular blade and other items. He is not sure if he is going to keep them, and I have no idea what kind, if any offer I should make. There are probable 15 boxes of research papers, and he went to conferences almost everywhere. I figure I might get it all moved by Friday, then I'll have to go through it. Paul
