MASSBUS disk emulator (Was: Unibus controller for MFM disks)

by jnc＠mercury.lcs.mit.edu

> From: Paul Birkel > Maaaaaybe there are three ribbon cables back there Sure looks like it, and running to a standard MASSBUS connector, to boot. (Not that I have any use for the latter - absolutely no MASSBUS cables at all. But one could just run flat cables from this, to one's RH11/RH70.) I don't see a second MASSBUS connector, wonder what they do about termination? Maybe it's onboard? So I guess one could only have one of these things per MASSBUS port? Not really a problem, of course! ;-) We _definitely_ need to put these things in 'production'. Noel

Reasonable price for a complete SOL-20 system?

by james＠attfield.co.uk

> From: "Mark J. Blair" <nf6x at nf6x.net> > Subject: Re: Reasonable price for a complete SOL-20 system? > > The gunstock wood origin story sounds more plausible, but less fragrant. > > -- > Mark J. Blair, NF6X <nf6x at nf6x.net> Not to rain on anyone's parade, but speaking as an owner of probably one of the first Sol-20's in the UK I would have to comment that the wood (which we always thought was a nice touch) was actually quite light in appearance and weight and if anyone had suggested wharf wood at that time I am fairly sure the suggestion would have been met with a degree of scepticism as would the suggestion of gun stock wood (I had achieved my marksman status by then and had some small experience of the feel of the stock in the hand and shoulder). For all that, I liked the SOL-20 as the best word processor on the planet at that time (with the Electric Pencil ROM) as it took great advantage of the VDM-1 memory-mapped display board to achieve what products like WordStar struggled for years to do. In fact, we often used to marry the VDM-1 to the Horizon for that very reason - that and the fact that we could then play ATC (Air Traffic Controller) on the North* which was a great mapped video game unavailable to serial terminals. It was also liked because it had a great keyboard with a good feel and, turn and turn about, could also have the North* drives bolted on to make a great little twin drive system. Another advantage was that we didn't have to solder up all the boards and assemble it like the IMSAI and some of the North* boards. I did love my IMSAI though, but the 8080 CPU was a drag as everyone was gung-ho for the 'new-ish' Z80 even though CP/M was still in 8080-land. Then came Cromemco and everything changed with CDOS and Cromix. People still wanted CP/M though - I recall even now assisting with porting CP/M to a Cromemco Z2 I took down to the Byte Shop in London one weekend. Of course, my IMSAI never flew better than when it was filled with Cromemco boards and a 299B drive on the side :) - those lovely blinkenlighten! Anyhoo - back to the SOL-20 - we always figured that the reason that the wooden side panels were featured was simply because the Horizon (the Big Dog at that time) was available with a very attractive wooden case cover for those who preferred something other than a functional blue metal case (in fact strangely remarkably similar to the blue of the SOL-20). Of course, although opinion may vary, either was arguably more attractive in an office than the metal mesh that SWTPC went with. I say this with some affection since as I write this my foot leans against the case of my old SWTPC AC-30 cassette interface. The innards gave up the ghost long ago but I can't bring myself to skip it as it brings back too many fond memories of a basement, an SWTPC processor, a lovely dual 8" drive unit and FLEX. In summary, if you don't mind an 8080 and you can get some decent drives for it (we were never very fond of the Helios drives) a SOL-20 is a very nice, well designed integrated system. I would have one again in a trice. James

ROM dumps of Intel MDS-2 IOC

by fulivi＠tiscali.it

Hi everyone, I'm looking for the images of ROMs installed on the IOC (I/O controller) board of Intel MDS-2 development systems. In particular I'm looking for the content of the character generator ROM (A19-2708) and of firmware ROMs (A50 to A53-4x2716). So far I had no success in googling them. My goal would be to contribute a good emulation of MDS systems to MESS, especially for what regards the look of the video terminal. Well, this is the plan, when "real-life" is not inteferring too much... Thanks a lot. -- F.Ulivi

One last epay for the day, TEC terminal

by jwsmail＠jwsss.com

Since some need to possibly use current loop, I was searching and thought it useful to bring this to people's attention. The TEC is also one of the terminals in the video I posted a few days ago related to "Jobs" if you care to look. I've used these and at the time the only problem I had was dropping them on your foot, they are not light. the vendor says that Bitsavers has the manual, which may make this a bit attractive as well, saving looking all over the place for documentation. The screen doesn't look great, but might be usable w/o a huge amount of work. Another thing that ones here may be able to use is that it has the video output option installed, so one could drive a modern monitor, or presentation projector in a display situation with this one. I think the ones we had were a bit fancier, and had a block of indicators on one side or the other that you could blink, this one does not. 1972-TEC-440-Serial-Terminal-/ http://www.ebay.com/itm/262674442502 no affiliation, just wish I had room for it, hope someone can use it. i'll throttle myself for a few days unless I see a random 360/50 or so for sale so I am not bothering those who don't like these.

Anyone with a CDC disk pack reader that can help Paul Vixie?

by spectre＠floodgap.com

Apparently Paul Vixie's got a CDC Hawk disk pack from an Alpha Micro AM-100/T that he'd like to get the bits off of (he'll worry about the file system separately). I have a controller card in an unknown state but I don't have any way of reading the disk pack, so it will probably be easier to do this in a separate working system, which does not need to be Alpha Micro. If you've got a means of doing this, I'll get you in touch with him. -- ------------------------------------ personal: http://www.cameronkaiser.com/ -- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckaiser at floodgap.com -- One learns to itch where one can scratch. -- Ernest Bramah -----------------

Xerox 6085 IOP firmware

by aek＠bitsavers.org

On messftp/uploads/6085_IOP_Firmware.zip I have been working on trying to get Smalltalk running on it, so I went through and checked all of my IOP boards for different revs of firmware. There are only two that I found, the later one added support for >80mb disks. The 6085 has a 80186 instead of the 8085 in the 8010, and there is much more code running on it than what was on the 8010.

Offer: HP-200 Series S/W

by silent700＠gmail.com

I have two boxed copies of Text Editor/200 for the HP 200-Series (aka 9826, 9836, 9816, etc.) and I probably don't need two of them, so I may as well pass one on: https://dl.dropboxusercontent.com/u/13043699/pics/HP200_1.jpg https://dl.dropboxusercontent.com/u/13043699/pics/HP200_2.jpg It's so new it's still in the shrink wrap, so I can only go by the text on the back (second pic link) that it includes both 3.5" and 5.25" disks. The HP Museum site has Teledisk images of the 3.5"s already, so you may as well leave it in its shrink for display (though I would like to see the documentation scanned, someday...) http://www.hpmuseum.net/display_item.php?sw=34 Who wants it for cost of shipping?

Unibus controller for MFM disks

If the system is simple it'll be easier to support, 110b is not, given the number of persons coming in from the other end so slowly. No one barely has a phone line anymore as it is, most (95%) of the external traffic will be telnet. If the bbs allows those few of us with phone lines to connect at 300 to 1200b to get to a handshake and resolve to a simple welcome screen for hardware testing purposes, that would be a good start. Get that running see what kind of traffic results, and plan phase ii from there. I imagine it will be best once this system is up and running that people call in on Sunday afternoon so visitors to the museum hear the inbound calls in real time like a sys op would running a bbs from his basement.

> From: Richard Schauer > My message to him, which I did save, is dated the evening of March 12, > 1997, and I seem to recall the list started a couple of days later. OK, so the 'unofficial' early archives which I'm hosting: http://ana-3.lcs.mit.edu/~jnc/cctalk/ do go back that far, so it doesn't look like we're missing much. The earliest ones there are from 13 March 1997, so we may be missing a few, but not many; the first posts are clearly 'hi, here's who am I' kind of things, apparently in response to an earlier message, which does alas seem to be missing. I scanned down the list, looking for names I recognized, and found this: http://ana-3.lcs.mit.edu/~jnc/cctalk/1997-March/0070.html which seems like it must be someone's very first post to this list!! :-) I do have the 'missing' archives (i.e. between Feburary 2005 and November 2014) in mail archive format, and once I figure out how to run Hypermail (this has been on my to-do list since last September, maybe I'll take a run at it today), I'll add them to the unofficial archives. Once done, it may take Google a few days to index them, but once that's done, it should be possible to search for content again. Noel

any interest in a power macintosh 6100/66?

by lyokoboy0＠gmail.com

I picked up a bit of an odball power macintosh 6100 a while back. It has a 486 cpu at 66 mhz in it as well, so you can run dos on it or something. Overall looks to be in somewhat working shape, but does not boot. I do not hear the hard drive spinning, I am guessing it is bad.I can get it to power on to the little flashing icon with the question mark. It came with a huge pile of cables for connecting extra monitors, and i should have a spare keyboard and mouse too. Anyone want this thing? I am open to offers. I can't absorb another world. I have too much on the table, and am just not interested in the PPC mac stuff. I thought it would be cool to have a machine that would run both mac software and dos, but I already have plenty of DOS machines here and did not bother. I have a couple of other tiny performa PPC machines that a monitor can sit on top of as well, those I know to be fully functional. those are up for grabs too. I can get pictures and specs upon request, that would require me to make a spot on my desk and fire them up. --Devin

Bootable 8" floppy needed for PDP-11/23

Hi, I have a PDP-11/23 system with a DSD-440 dual 8" floppy drive. On reset, it prints: 28 START? and waits for the operator to insert a bootable 8" floppy and type DY0. The problem is I do not have a bootable 8" floppy. The DSD-440 should be compatible with either RX01 or RX02. Can anyone on this list help me out with a bootable 8" floppy? I will gladly pay for the floppy + shippng costs. Thanks, Scott PS: Pictures of the system can be found here: http://sierracircuitdesign.ddns.net/temp/pdp11

According to the first page, the single volume Sun-1 System Reference Manual from July 1982 was replaced by two volumes the User Guide, which I have, and the Programmer's Reference Manual which I do not have. The older manual is probably more useful but this one is expanded (according to revision page) to include 1/2" and 1/4" tape drives and Fujitsu disk drives. I see that the CDC Lark operation is in here, the Sun-1 that I dealt with had a CDC Lark cartridge unit and I still have some of the old Lark cartridges and no possible way to read them. -- Richard Loken VE6BSV, Systems Programmer - VMS : "...underneath those Athabasca University : tuques we wear, our Athabasca, Alberta Canada : heads are naked!" ** rlloken at telus.net ** : - Arthur Black

ASR 33 buzzing

It's not a matter of bothering.. it's a matter of not knowing what I'm looking at yet. ?I was checking what I thought were all the clutches in the back.. they all seemed good. I guess changing caps would be a smart idea right off given they look original. ?I'll check the diodes too. ?I am just nosing around.. given it wasnt shorting out when it left.. I'm concerned something might have shifted in transit.

You'd have found that the clutch that reset the keyboard could be released. The buzzing may also be related to your fuse blowing the supply that feeds the receiving coil may have a shorted diode or capacitor. That would both explain the fuse and the buzz.

Doesn't work.. the bar is stuck.? At any rate, I put the metal piece over it and the carriage returned on its own (spring action).? I then wound the motor some more and got a bell sound.? After that, the keys started to work properly -- I can see the little arms (code bars?) changing as each key is pressed. Thought maybe if the keyboard was jammed that might short the motor.. but still blows out fuses. AFAIK the unit was working before it was shipped, sort of.? The seller mentioned powering it up and doing a carriage return successfully before shipping.? I'm inclined to think something happened during shipping.

Getting out of the hobby

by jnc＠mercury.lcs.mit.edu

> From: Jason Howe > I really really want to aquire a PDP-11 ... Given the price of these > things in the world right now... If you're willing to live with a QBUS machine, and not a UNIBUS one, it doesn't necessarily take a mountain of money - if you're patient and wait for deals. I've bought 11/23 CPU boards for as little as $40 recently, and memory and serial interface cards for console are on the same order of money. And I got a BA11-S box, complete with power supply and backplane, for a little over $100, IIRC. The real hangup is mass storage; the older drives, at least, are all real money now. I don't know about the later ones (from the uVAX era), those seem to be cheaper, but I don't know anything about them. If Dave B and I can get the QSIC project to the production stage, that would probably alleviate that side. Noel

Getting out of the hobby

by lists＠loomcom.com

Hey folks, Recent activity on the list, especially the "Ka... ching!" thread, has had me reevaluating a lot of what I get out of this hobby. I think there are two things going on that make it less fun for me now: The money, and the age of the stuff. I'll try to explain. I've never been a real "collector", I suppose. I don't feel a burning need to fill every hole in a product line, or to put things on display. I've also never been in this for the money, far from it. No, the only reason I've ever collected classic computers is because I've loved playing with them. That's really all there is to it. I enjoy the sights, sounds, and smells of firing up vintage computers and seeing them work. On the money front, as I said I've never been in this for the money. There was a time when most of this stuff could just be had for free, and that was fun! Going on rescue trips was a blast. I'll never regret driving down to LA from the Bay Area to rescue a PDP-11/34, or the time that a bunch of us got togethr and picked up an 11/45 and an Imlac PDS-1 >from Bill Gosper's house. What a time that was -- I didn't even keep any of it, I was just there for the rescue and the camaraderie. But nowadays, there's so much less of that. 99% of what trades hands seems to go back and forth on eBay for real big bucks. And that's probably just the sign of a maturing hobby, but it's not really what I enjoy. And secondly, lately there's been a lot less of "firing up vintage computers and seeing them work", and a whole lot more "carefully replacing capacitors and praying that the vintage computer will still fire up". We've reached the point where the hardware I love is dying. It's been dying for years, I suppose, but now it's in hospice care. And, frankly, that part of it is so much less fun for me than actually using the systems. Am I just lazy? Maybe. And don't get me wrong, I've learned SO MUCH about electronics from taking care of these systems, so I don't consider it a loss at all. It's just not what I want to spend my time on. I've been ruminating on all of this pretty hard for the last couple of months, and I've concluded that my enjoyment just isn't there any more. Now that I'm surrounded by a bunch of stuff that I'm not getting much out of, I feel like I'm being weighed down by the hobby. I think it's time for me to move on and concentrate on other things. I'm not sure yet what that means for my current collection. It's already much smaller than it once was, as I've found homes for a lot of things over the years. I've moved a lot, and every time I've moved I've found homes for things I didn't want to take with me. It's probably time to do that again, only without the moving part. I think probably I'll have one last big "sale" of stuff, which I'll post about here. At this point most of what I have is vintage home computers, terminals, and QBUS PDP-11 stuff, so not everyone will be interested in it -- but maybe some people will. -Seth -- Seth Morabito web at loomcom.com

the perennial '937' problem just installed 6085 XDE 5.0 from floppies but there is no option in the installer to load and setup to boot settimedove.boot from the copilot volume someone must have figured this out on the other hand, since none of the compilers or actual useful stuff is installed, since you're SUPPOSED to fetch this off the XNS network, maybe not.

Panelman Update.

by rodsmallwood52＠btinternet.com

Hi Guys Having established a good stock of panels. I now have got a little time to move my PDP-8/i project along a bit. The front I already had . A kind list member let me have a lights board. I built and and tested it It is compatible with the original /i in form, fit and function. This means you could attach wires and paddle (Filip Chip Type ) boards to it and plug it into a real /i and it should run. As I have said before the /i is a wire wrap back plane and loads of flip chip boards. It would not be possible to duplicate it. So modern technology front and center please! The Raspberry Pi is cheap, available and I have one. I also found a 32 port Pi I/O expansion board that you can have up four of on one Pi. SimH runs on a Pi and it does do 8/i emulation. It looks like SimH is written in C. Not a language I have used but I'm sure the hundreds of different versions are all very good ! Hopefully you can declare and call SimH functions under Python. The four 32 port Pi I/O expansion boards I ordered should be here to-day or Monday. They are accessed using the I2C bus from the Raspberry Pi The switch panel is a bit more of a problem. I'm sure copies of the DEC butterfly rocker switch will become available. in the meantime commonly available rocker switches will suffice for development purposes. Although Oscar multiplexed his lamps I may be able to find out how the system signaled it needed to update the lamp display.

Yeah I'm sure we must have bad cap(s) here. ?I think pretty much everything is original on this thing. ?I've no idea how old it is. I'll have to read through the manuals and figure out where the cap is. ?I'm assuming it must be round.. although directly under the fuse is a little black box connected to it. ?

A shorted (or open..) cap can certainly cause this issue. Shorted and it draws excess current in the cap, open and it may prevent motor starting / running which likewise draws excess (stall) current, but in the motor windings. Also, it shouldn't be too hard to isolate the motor assy. itself from the rest of the circuit - lift the correct lead(s) from the AC power distribution system. It may be much easier if you can deal with the motor / cap assy. as a single entity, rather than within the rest of the complexity. This is just generic advice from a guy who's never fixed a 33. But assuming yours has the standard AC synchronous motor, it should all apply. Motors only draw excess current for a very few reasons - overload / stall, shorted windings, bad start / run caps and possibly associated start / run relays.

Gould 32/77

> From: Jon Elson > we got an 11/45 used and ran RSX-11M with about 4 users on it, it > worked VERY well About when I first got to MIT ('74), they were running the main introductory programming course for CS students (6.031, for those to whom that means something) on an 11/45; it had (IIRC) about 30+ Decwriters hooked up to it. It ran a home-rolled OS called 'Delphi' (written in Macro-11, I suspect); the course covered assembler, Algol (compiled, I think - but it may have been interpreted, I'd have to check) and LISP (interpreted). ISTR that the response time on the machine was usually pretty good. By a very odd chance, some years later I got that very machine in a trade, and it became the main time-sharing machine (running Unix V6) for our group (CSR) at LCS (545 Tech Sq). We beefed it up with an Able ENABLE and I think 1MB of memory, and IIRC the optional Able cache for the ENABLE, and it was _quite_ zippy - I think 'mips' returned about 3.0, about as fast as the DSSR 11/70 on the other side of the 5th floor at TS. Of course, it didn't have the mass storage I/O bandwidth of the /70, but we were very happy with it. > of course, when we moved up to a VAX, that was even better! Heh. Give me an 11/45 with an Able ENABLE any day! :-) Noel

TeleVideo progress

by isking＠uw.edu

Hi all, I've posted looking for help with a TeleVideo TPC-1, and I've heard a lot of crickets - apparently this isn't a commonly held machine. :-) But I've made progress with it, which I want to share. When I first got it, the display would light up and ask me to insert a floppy. Doing so would promptly douse the display. I figured, 'power supply', and recapped the entire thing - after the venture of figuring out how to open the case! I found a post in netnews that strongly suggested TeleVideo had suppressed information about opening the case to protect their service centers' business.... It's an odd combination of 'push there, pull there and be bold', but I got it open. Recapping was a success, and the machine attempts to boot from disk 0 - and tries, and tries, and.... I figured that drive 0, being the most used, might have issues, but wasn't looking forward to pulling out the drive cage and swapping them as a test. But then I noticed that drive 1's circuit board was visible, and I rejumpered it to be drive 0 - and success, the machine booted into CP/M! Sure, I could just leave it as a single-drive machine, or swap the two and pray - but this is a restoration. I've ordered an exact, tested/guaranteed working replacement from ePay, and I'm going to have everything working to spec before I snap this thing back together. Yes, I'm having fun. :-) -- Ian S.

Gaming on old systems (was Re: Twiggys [was: Re: ka... ching!])

I am actively seeking lists of favorite games on all platforms prior to 1995. Specifically, things that require Windows and a Pentium and newer are out of bounds. I'm attempting to breathe some excitement into a retro-gaming meetup I hold a few times a year at our hackerspace. I'm already bringing the hardware - to date, Commodore PET, Commodore 64, Apple II, Atari 2600, PDP-8 (emulated for now), and curses-based UNIX games, and would like to add more platforms. I'm especially interested in any favorites that run on dumb terminals (I have numerous ones to bring in, and have a VT220 already in the collection). Yes, I know a bunch of games that run on those platforms. I'm looking for other people's favorites because that is what will stimulate interest in the meetups. I already bring my own favorites, but learning what other people remember fondly - tapping into their nostalgia - will be a big help. In bounds are any machines from the 70s and 80s that a) are common enough to lay hands on or b) have a reasonable emulator on modern platforms. I will probably add DOS games to the list, but that's not the focus at first - 8-bit microcomputers and minicomputers are at the top of the list. Emulation via simh is acceptable but I'll try to dig up the original hardware where possible. If you've played anything in the past 3 years, I'd especially like to hear about it since that speaks to enjoyment and replayability. If you like it, someone here will probably like it too.

When I look into the WayBackMachine I see https://web.archive.org/web/20141025062159/http://www.classiccmp.org/piperm… https://web.archive.org/web/20150103042513/http://www.classiccmp.org/piperm… that between October 25th. 2014 and January 3rd, 2015 some incident happened which wiped out the archives before November 2014. How comes that the 'classical computing' lost it's memory ?? With best regards, Walter P.S.: It's a bit astonishing to me that a list like cctech, which is in some ways about history, has lost it's own history, and even doesn't seem to care about it.

Gould 32/77 (was: NWA auctions)

by jnc＠mercury.lcs.mit.edu

> From: Brad H > the 11/45 is from around the early 70s right? First released in '72, if memory serves. It was in production for a _long_ time, though - no later model really replaced it (if you wanted a mid-sized machine with a lot of crunch), unlike many of the other -11's (e.g. /05, /40, etc). Noel

Any Kryoflux, Discferret, Catweasel, or other floppy flux images wanted

by spacewar＠gmail.com

Would anyone care to donate floppy disk flux-transition images for use in development of utility software and for regression-testing the same? It would be much appreciated. Images from "normal" floppy formats (IBM FM and MFM, e.g., TRS-80, IBM PC, or almost anything using 177x/179x/279x or 765/8272 family controllers) and obscure formats (DEC RX02, Victor 9000) would be welcome. I'd especially like to get IBM 23FD "Minnow" disk images, but I'm not holding my breath for that. If you send me any images, a brief description of what they might contain and/or what system they're from would be helpful. I don't need to be able to do anything with the content; I just want to verify that I can extract the content from flux images into sector images. If you send me any images that you don't want made public, let me know. Thanks! Eric

IBM 6715 / actionwriter "daizy" typewriter "RS232" port ??

by gerardcjat＠free.fr

I know it is a long shoot ! The IBM 6715 / Actionwriter was one of the last daizy wheel typewriter made by IBM Germany. ( said to be made to last at least half century, German design ;-) ) It has "kind" of a RS232 port on the back, I was unable to find any information on this port which was intended to support two "extremely rare" !!! IBM options one beeing a REAL RS232 port, the other some kind of display of the two last line typed. I wonder if someone has even connected this typewriter to a computer. It would be fun to use it like a "modern" TTY but I think the problem is probably that this typewriter expect a "lot of" (??) proprietary commands to set type spacing, margins, baud rate etc .... Any advice ?? Any help ??

Highway interface [warning contains an ebay ref], but is an old VMS network interface

by jwsmail＠jwsss.com

I found an interface I've never seen, a Fisher Rosemont Highway interface. I don't know much in the history of Dec / VMS, but am guessing this is for Vax system only. HIGHWAY-INTERFACE-49A8569X052-62-FISHER-ROSEMOUNT-DC6450X1-HA5-40B1745-W-CABKIT-/ http://www.ebay.com/itm/371645465846 I found this flyer sheet about it with the info on the interface. I'm guessing if you don't have one of the central boxes, you have some expensive gold scrap in these boards. http://emersonprocess.com/systems/support/documentation/provox/docvue/Produ… The fact this reference is where it is suggests there must be embedded systems using it to justify the price though. Also the other manual referred to indicates that there is something that runs on NT, as well as a mention of AIX. http://emersonprocess.com/systems/support/documentation/provox/docvue/CHIP/… thanks Jim

PDP-11/23 system for sale in Portland Oregon

by scott.l.baker＠gmail.com

Update: After removing all the boards, checking jumper settings, etc. and reinstalling everything again. I am please to announce some progress. The PDP-11/23 now boots up to the diagnostic monitor. Thanks very much to people who replied with technical help and particularly to Glen Slick who helped with board identification and configuration and help me fix the QBUS slot assignments. The original slot assignments were wrong and the bus termination was not at the end of the QBUS. The current slot assignments are: Row 1: AB - M8186, CD - 256KB memory Row 2: AB - DSD disk interface, CD - grant continuity Row 3: AB - M8028 DLV11-F async interface / console port Row 4: <empty> Row 5: <empty> Row 6: <empty> Row 7: AB - M8016 KPV11 power fail / line clock Row 8: <empty> Row 9: ABCD - M8012 BDV11 diag ROM / QBUS termination I have added a few pictures here: http://sierracircuitdesign.ddns.net/temp/pdp11/ Next Steps 1) Find the manual for the diagnostic monitor to figure out how to run some test. 2) Locate some 8" floppies with RT-11 loaded and connect the floppy drive

Video clip from ABC Nightline 1981 with Steve Jobs

by jwsmail＠jwsss.com

If you read further, I decided to post because of the number of machines I've either worked on or owned which were in this. I think for instance the terminals @ about 1:29 are Datamedia. I had several of the beasts. "Academic researchers... is the narration" https://youtu.be/3H-Y-D3-j-M Laughed at some of the discussions in the last half, but worth watching. Has about as much of Job's in it as one can stomach. And is probably before the cult of the Fruit company thing was taking hold. Scenes showing the Apple2 or ][ as some will want, and the Apple3 are shown from the factory. Also appears that Apple was operating out of a hive of buildings, not a central one at the time. Five years into Apple's operation. Thanks jim

Micro Fiche Library.

by rodsmallwood52＠btinternet.com

Hi All I have just had a huge DEC Miro Fiche library given to me. It has the portable (weighs a ton) reader with it. On trying it out. I found the results were awful. A good clean of the light path and removal of some disintegrating foam improved things no end. That left two issues: 1. The reader was for x 42 but the fiches are x52. 2. The plastic fiche holder consisting of two sheets of stiff and clear plastic connected together at one end is scratched to hell. I'd like to work to-wards scanning all of the library into a system. Anybody know anything about fiche scanners. Rod -- PDP-8/e PDP-8/f PDP-8/m PDP-8/i Front Panels ex Stock - Order Now

large Wire wrap cards

by lyokoboy0＠gmail.com

I picked up 3 of these a while back, I am unsure of what kind of machine they go to. The plan was to use them to prototype on, but then I found some even better wire wrap boards and set these aside. I did not want to have to go through getting all the wire off of them. They are up for sale or trade if anyone is interested, I am just curious if anyone knows what they came out of. gallery : https://postimg.org/gallery/1tizoqomi/ --devin

Mark-8 opinion question

by vintagecomputer＠bettercomputing.net

I asked this on vcfed and I don't know how much overlap there is here so I apologize if this is hitting all the same people over again. As some are aware I recently won an auction for 9 original Mark-8 boards (it has 4 1k RAM boards). To say I was elated would be an understatement - I certainly have some unusual stuff in my collection but this is something truly rare. And these are rare both in their own right and for what they are - unused. Pretty much spotless. I feel kind of in a bind about it now though. As an amateur historian, my first impulse is to stick em in a frame and hang em. Not even lay a finger on them. But I've a stubborn practical side. Like that guy that has an original AC Shelby Cobra and actually drives the thing. He was asked why he'd actually drive such a rare and valuable vehicle and he said 'What's the point of a car you don't drive?'. But then he can say that - that Shelby doesn't have zero miles on it. Realistically, I'm never likely to own a complete, vintage Mark-8. There are simply too few of them and I couldn't afford one even if one popped up (I could afford the computer, just not the divorce afterwards :)). So here I am with one path to having one that would be, by virtue of the boards, way more legit than a clone, but still have that 'built in 2016' asterisk beside its name for serious collectors. Anyway, I'm just soliciting opinions from those I haven't already heard from. This is just for the purpose of discussion, because I'm sure this isn't the first and won't be the last time somebody buying vintage gear runs into a situation like this. Whatever I end up doing, it will not happen for years anyway. I'm not at a skill level yet to pull it off, and I'd still like to build that clone first and see what I achieve before touching priceless originals.

If it were me, I would not build on the originals. I would engage someone to repop the boards, their labour cost would be recouped with the sale of a few sets. What I would do is make sure the repops are easily identifiable as such so that they are not in future passed off as orignals at the same time as preserving your investment in the real thing. I recall seeing photos of a WWI biplane fighter being restored by the Smithsonian, and on the new pieces of wood they used to replace damaged or missing fillets, longerons and other parts of the airframe they had clearly stamped 'REPRODUCTION' so that future conservators would know > what was original and what was not. > Steve. Thanks Steve. No honestly.. I just like to talk about stuff like this. ?My mind is nowhere near made up. Regarding repopping.. I thought this had already been done by Obtronix or someone? I saw repop boards on ebay that I think the seller was trying to pass off as original. ?I'm wondering now how they made theirs and if in repopping mine I'd just be reinventing the wheel, or if someone could make them look that much more like the original.

Getting out of the hobby

Front Panels - Update.

by rodsmallwood52＠btinternet.com

Hi Firstly I am pleased to be able to say I have five different PDP-8 front panels all in stock. Secondly a big thank you to Jack Rubin for mentioning my panels in his presentation at the Chicago show. I have the artwork for the PDP-8/L done and I'll get a run done as soon as I get enough interested parties. Thanks to Vince I have been able to make a working PDP-8/i lights board. As we all know the 8/i is made up of a wire wrap back plane and loads of flip chip modules. I am only mad not totally insane. So reproducing that lot is not possible. So its the Raspberry Pi and simH route for me. First job is to go and have another look at what Oscar did/is doing. I know he muxed the lamps on his board. He usually open sources everything. In keeping with my plug compatible philosophy I'll go as far as paddle cards and DEC style edge connectors on my PiBoard The switches are the butterfly rocker type. I should be able to pick up an odd one as a sample. I know Oscar is looking at this whole question so I'll get an update >from him.

I know this is a very long shot, but I'm looking for Figure 6-13 >from the Part I Technical Manual on the ENIAC by Adele Goldstine. In the table of tables at the front of the manual, this table is one of three listed as "in an envelope attached to the back cover." Neither the scan on archive.org, nor the printed manual from Periscope Film, appear to include these tables. Does anyone by any chance know where a scan of any of those three tables (6-13, 7-4, and 8-13) might exist? Thanks in advance, BLS

VCF Midwest 11 Videos!

by silent700＠gmail.com

I am pleased to announce that the full lot of speaker videos from this year's Vintage Computer Festival Midwest have been posted to our YouTube channel. There is a play list of this year's videos here: https://www.youtube.com/playlist?list=PLE-Iywr9LQESedwj_46tFIaPoyrUf-mHs In addition to the fine lineup of speakers, there is a 7.5 minute "highlight reel" showing many of the varied demos and displays, along with some nice stop-motion footage of the crowd at various times of the day. The direct link for that is here: https://www.youtube.com/watch?v=adQIMM7cVg0 Although he is not on this list, I want to thank our full-time "A/V nerd," Jim Leonard (AKA Trixter http://trixter.oldskool.org), who handled all aspects of production, from manning the camera and mixer during the talks and clipping the lav mic on the speakers to his expert editing and production of all the footage. The highlight reel was his idea, too :) We're really proud of our interesting, diverse set of presentations this year, as well as having kicked the production quality of our videos up quite a few notches. We hope you find something of interest among them. -j

Chip info reqd: MR9736-002 CRT controller?

by witchy＠binarydinosaurs.co.uk

Hi folks, The restoration of the STC Executel 3910 I mentioned the other day continues with picture help from another collector who bought one at the same time I did. I've got it powering up and the tiny monitor is trying to display something but the horizontal hold has gone so I'm suspecting dry joints given the state of the back of the monitor board and the microcassette drive next to it when I opened it up for the first time. It's been cleaned and the leaky battery removed since then, fortunately there's no trace damage from the alkali. The display board is powered by the chip in the subject line and neither myself or google has heard of it. It's a 40 pin DIP that doesn't seem to be pin compatible with any CRTC I'm aware of. Anyone? -- Adrian/Witchy Binary Dinosaurs creator/curator Www.binarydinosaurs.co.uk - the UK's biggest private home computer collection?

The assembler is a program that transforms (somewhat) human-readable text into machine code.? There a few ways to go about structuring this workflow.? So far I've been using a cross-assembler that runs on a different system - for example, the original UNIX was cross-assembled on a GE-635 mainframe for its PDP-7 target.? There are native assemblers as well.? These often assumed some sort of secondary store, whether punched tape, magtape or disk, that might hold intermediate stages of assembly and certainly the final product.? A common workflow was: - load native assembler program from <media> - start native assembler program - tell native assembler program where to find the source (which media) - native assembler reads in source, transforms it to object (machine code), sends the results to <media> - programmer loads object from <media> and runs it If you're loading an assembler program from tape, you probably need to give the monitor a 'go' instruction once it's completed (that's how MIKBUG works, anyway).? The assembler may prompt for the input source or may just assume that once you say 'go' a tape is loaded and ready to be read. How do you create the source?? If you're doing it natively, you need an editor that runs on the platform and can send the resulting text to <media>.? Or again, you can write your assembly source on another platform and create (or emulate) appropriate <media>. I hope that helps.? Cheers -- Ian -- Ian S.

So the Cliff Notes version of this is I need to find a copy of SWTPC's assembler? ?(Pretty sure I've seen it referenced somewhere)

SCSI Tape Emulator

by dave.g4ugm＠gmail.com

Folks, I am "playing" with a small VAX and want to install software onto it, some of which are in SIMH ".tap" format files. I was thinking it would be nice to have a SCSI Tape emulator that worked a bit like the USB floppy emulators that are about. So it would plug into the SCSI bus and allow ".TAP" (and other tape formats) stored on some kind of flash memory, say USB or SD card perhaps, to be read by real hardware. Does this sound usefull to any one? Any other thoughts on how this could be achieved? Dave Wade G4UGM & EA7KAE

Data on a Platter!

by silent700＠gmail.com

Here's a scan - and special bonus audio tracks - of a brochure and 7" record I found on ebay recently: http://chiclassiccomp.org/docs/index.php?dir=%2Fcomputing/EG%26G "Data on a Platter" from a company called EG&G (anyone heard of them?) describes their vinyl (as in analog audio record) data storage scheme and how it will fit into your business. There's no date anywhere but the brochure is a great example of 60s typefaces, not to mention language. The recording includes examples of how the data sounds if played on a regular phonograph. Who's up for decoding it? -j
