Hi!? There have been several requests for another round of the S-100 Bus Extender PCBs.? Since these are essential tools for any S-100 builder I think we should get some more.? We need 20 PCB pre-orders so I can make a manufacturing order. The S-100 Bus Extender board is ready for ?production?.? If you would like to get one or more of these very useful boards please do the new usual pre-order.? I will set aside your board so you get them as soon as they arrive. Here is a link to S100computers.com website with information on the updated S-100 Bus Extender board: http://www.s100computers.com/My%20System%20Pages/Extender%20Board/Extender%2 0Board.htm The PCBs will be $20 each as per the usual arrangement.? Shipping in the US is $3 for a single PCB and $2 for each additional PCB.? Shipping internationally is $10 for a single PCB and $3 for each additional PCB.? This is for the bare basics USPS first class postage with no tracking or insurance.? The builder assumes all risk of delivery as per usual arrangement. Please send a PayPal to LYNCHAJ at YAHOO.COM with the subject ?S-100 Bus Extender? and I will reserve your board(s).? Thanks and have a nice day! Andrew Lynch PS,? We are still doing another order for S-100 Buffered Prototyping board bus and have 6 boards in the queue.? If you would like one or more S-100 Buffered Prototyping boards please let me know.? The pre-order arrangements are identical to the others but please send them in a separate email so I can keep things straight on this end.

cctalk Digest, Vol 122, Issue 20 - Re: Barrys collection - the free stuff

by johnwallace4＠yahoo.co.uk

One day I'll learn to type; till then I will just apologise from time to time for sending half composed messages (and using a rubbish email client). Sorry! > -- Vax 1000 BA-23 Note that it's possible (probable?) that this is an rtVAX 1000, with a KA620 CPU board, and possibly no mass storage in the BA23. The KA620 is closely related to the KA630 (MicroVAX II) with one small but significant difference. The rtVAX family (not to be confusbed with the ftVAX) were sold to run DEC's distributed realtime OS, VAXELN, which could be network booted (or boot from disk). Some rtVAXes had slightly cut down memory management relative to ordinary VAXes, a "feature" which meant they'd never run VMS. Some folk won't mind the distinction, others might. VAXELN is an interesting piece of software in its own right but doesn't seem to be in the VMS Hobbyist program. Regards John

[N8VEM-S100:1971] S-100 80286 CPU PCBs have arrived!

by monahan＠vitasoft.org

Hi All, I will do a detailed write-up on constructing/testing this board when mine arrives. For those wanting to get an early start, a reminder, be sure to use a mica insulator between the 5V regulator and the board (or as a last resort a pair of small washers) . You do not want the traces in that areaon the front of the board touching the heat sink/ground.

Hi! The S-100 80286 CPU PCBs have arrived and I have shipped all the pre-ordered boards. The boards look great and the order has been a huge success! There are only two (2) boards left in case anyone wants one. I am really looking forward to the first reports of the S-100 80286 CPU boards "in the wild". This is going to be fun!

ROM Image wanted, Superbrain

by jbensadon＠hotmail.com

Hi, I've got a Superbrain computer from Intertec that I'm trying to get running. The EPROM is blank (all FF's). I'm guessing over time it erased itself. I tested my eprom programmer with another 2716 just to be sure. Recently, I got access to another Superbrain, but it's EPROM was also bad, (all 00's). I'm hoping someone, somewhere, can make an image of this Eprom and send it??? Many Thanks, Josh Bensadon, Toronto, Canada

OT: Help with BEST competition

by mtapley＠swri.edu

All, Two of my kids are competing in this years BEST robotics design competition. Rules are here, FYI: http://www.bestinc.org/b_game_rules.php The competition is to build a robot which will assemble logic element stand-ins into logic gates and CPU elements (not actual ones, everything is sylized so that the robots can be made out of easily available macroscopic materials). However, an important element of the competition, on which the older child is working, is to write a "business case" for such a robot - do market research, in essence, and convince investors why such a device is useful. When I heard "market research" I immediately thought of this group as probably the best concentration of knowledge anywhere on why anyone would want to build custom-configured logic circuits as opposed to using a generic general-purpose microcontroller for the same task. I *think* I know part of the answer. My thoughts are generally: 1) Anything custom-configured to the task at hand can have number of logic gates, number of transistors, etc. optimized to that task. Register length can match precision of sensors, etc. Thus, *all else being equal*[1], minimum resources (power, heat generated, etc.) will be required by the resulting system. 2) Anything custom-configured can have performance optimized - state machines or flip-flops (vs. combinatorial logic) implemented only when necessary, path lengths shortened where possible, etc. to provide minimum feedback-control times. 3) Anything custom-configured can have minimum complexity. For mission-critical applications, this means it becomes exponentially easier to "prove" correct control system functionality and to predict performance even in the case of SEU or other problems; general-purpose microcontrollers are much more difficult to validate in this sense. I would love comments, and particularly references (places to look on internet, conference proceedings, etc.) from anybody who would care to provide them. Replies on the list to the extent you think they are on-topic, or direct to me and my cc'd daughter if off topic. Thanks in advance! [1] I know microcontrollers have the advantage of gate size *far* below what any discrete components currently can achieve; that's the caveat I'm trying to leave with the "all else" comment. I assume part of the business case has to be that a robot assembling logic designs can be made arbitrarily small so that gate feature size for the discrete logic can compete with gate feature size for large-scale IC's. -- - Mark 210-379-4635 ----------------------------------------------------------------------- Large Asteroids headed toward planets inhabited by beings that don't have technology adequate to stop them: Think of it as Evolution in Fast-Forward.

AT&T Sceptre

by kylevowen＠gmail.com

Hi all, I found a Sceptre set-top box without the keyboard a while back, and finally got around to checking it out. Just for curiosity's sake, I took it apart and photographed the insides. Pictures for the equally curious: http://imgur.com/a/cibFD Has anyone managed to get a Sceptre or other Videotex box to do anything besides keeping papers from blowing away in the 21st century? I have an Asterisk server and analog card that I was thinking might could send some data to the box to display some messages, etc. How feasible would this be? Is there protocol documentation available? Also, is this box basically useless without the wireless keyboard? Does anyone have a spare keyboard? Thanks, Kyle

DEC Terminals, free P/U in CA

by dm561＠torfree.net

>From the VC forum: I have several old terminals that have been wrapped in plastic for the last 3 decades or so that I'd like to give away: (a) DEC VT-131 (b) DEC VT-241, and (c) a Wyse 350. All three have keyboards and original manuals, and all were in excellent shape when I put them away. I live in Moreno Valley, CA, and I would prefer to have someone pick up whatever they want if possible. If anyone is interested I'm willing to plug any or all in to make sure they still power up and take them to UPS, but boxing and shipping is on you. I don't know if this is the right place to list these, but I thought I'd try to see if anyone wanted them before I just recycled them. Seemed a shame to just scrap them, but I need the space. (No email addy; PM on VCF if interested). m

Looking for some Sun 2 parts

by earl＠baugh.org

After coming very close to getting a couple of parts for my Sun 2/120 and striking out yet again, I figured I'd ping to see if anyone has any other leads. I'm looking for a Sun 2/120 front plate (side plates would be great too, I have some that need restoration, but if I could find some ones in better shape, would save some time). I was chatting with someone in CA who had a empty 2/120 chassis, which also would fit the bill... I have a chassis but wouldn't mind have one to "build up from"... I would like to get one and get it really cleaned to start from, without tearing out everything >from the existing one that is still "together"... would make it easier to work from, since I have 2 back-planes and 2 power supplies... (and it's not clear if both sets are good...) Also a Sun 2 Keyboard and Sun 2 mouse. Drop me a mail off line if you have a lead, or have some to trade/sell. Earl

"Gold recovery" sellers on eBay

by nf6x＠nf6x.net

What's with all of the sellers on eBay in the Vintage Computing section selling ICs and boards for "gold recovery"? Are they just scamming ignorant folks, or do they actually believe they're selling something of value? Do people believe that if they buy some PCB for $25 shipped, there will be more than $25 worth of gold on it after they manage to etch away everything but the gold with acid? Am I missing something, or are those sales about as honest as the typical 419 email scam? TANSTAAFL... Sorry, but I just had to rant there for a moment. -- Mark J.

Moving

by ggs＠shiresoft.com

I have to say that it's been an adventure. I'm almost done moving everything (computer wise...the house is next summer). Just took a load of 12 pallets up to the new place (I could have fit 14 in the truck but I had figured the truck from previous moves would only hold 10-12 and I'd only made 12 ready). I put some picture up of how everything looks after I unloaded the truck. The link is here (there's before and after pictures of the shop...just click on "Almost Moved" for the "after"): http://www.shiresoft.com/new-shop/Shiresoft/Almost_moved.html. I didn't take pictures of the "basement" where I had moved all of the totes a few weeks ago to make enough space for everything else because there's not too much to see other than about 100 totes. ;-) BTW, there's still stuff to be claimed before it goes to be scrapped including a lot of uVAXen (including a VAX 4000/700 I just unearthed today), uPDP-11s, 11/34s, 11/44s, a Sun 4/110, DEC Rainbows and a DEC Robin that I "discovered". The final weekend for picking this stuff up is 10/19 and 10/20. I'm taking the final load up on 10/26. Anything after that will be scrapped the following week (there's some exceptions for folks that are picking up/shipping some *big* stuff...they know who they are and don't have to panic). So if anyone wants anything let me know (no I won't ship anything...it defeats the purpose). TTFN - Guy

Fortune 32:16

/delurk Hi all Do we have a Fortune 32:16 guru on the list? I've searched the archive and there's some stuff back in 2005 but that's about all I could find. Reason I'm asking is I unearthed the disks I copied off the university's Fortune 32:16 back in 1987/88, so I ImageDisked them. But there's pretty much no information on the hardware out there. Seems to be an interesting system, Z-80 running I/O, TTL memory manager, some kind of PAL playing copy protection... would be a pity if the details have been lost. W

old CAD workstation used for MEDUSA

by a13stesk＠student.his.se

Hello In the mid 80ies i was at school in Sk?vde Sweden. At that time that school had a PRIME 9955 system together with the normal serial terminals and also a fair number of specialist CAD workstations. The CAD stations was used for MEDUSA and another Electronic CAD package (we did PCB designs in that system.) I have two questions (because of a foggy memory): what was the maker of the work stations (or who could they be) ? and could someone name a number of pcb design programs for PrimOS ?

Mac 128K board repaired

by ethan.dicks＠gmail.com

Hi, All, For those that might be following the saga (and especially for those who chimed in along the way), I wanted to let people know that the board is running and boots Finder 1.1g off of suitably-formatted floppies (single-sided MFS). Despite numerous reports on multiple Mac discussion lists, et al., A Sad Mac with 6 bits set was corrected by replacing the 6 indicated chips. I can only imagine that the numerous reported failures that were unrepaired by replacing the RAMs were problems with bus buffers or some other thing that dragged down multiple bits on the data bus, or perhaps traces/vias damaged in the repair pricess. In my case, thankfully, it was no more than diagnosing and replacing a few chips (FWIW, I was able to verify that in advance by dry-fitting known good DRAMs on top of the bad ones and observing a positive change in the power-on diagnostics). So that's done, and now it's time to clean and lube the eject mechanism on an old 400K drive, then turn my attention to getting an Imagewriter I working again. I'm sure I can make a cable but with any luck, I already have an official Apple cable in my box of old Mac parts. Not sure about ribbons, though. Thanks again for all the suggestions. -ethan

Moving sale

by ggs17＠me.com

As you may remember, I'm moving. This has required a significant amount of work to get stuff packed. I've been making some progress. I have dug out enough to be able to list *some* of what I have that I don't want to move. Please make offers. I'll consider anything "reasonable" (I'm not expecting eBay prices but I'm not going to give the stuff away either). I'm trying not to ship stuff because frankly I don't have the time. If you're not in the area and really want something it'll probably be best if you can get someone who's local (San Jose/San Fransisco California area) to pick it up and get it shipped. My plan is to get everything moved before October 1. After that anything that I'm not moving will go to Weirdstuff. I've put a lot of stuff on pallets for my ease of handling. You'll get a "deal" if you take the pallet as-is (ie take the lot). I have a lot of small stuff. Sorry but I can't search for little items. If you come by I'll let you search through the various piles of stuff but I won't. OK, so much for the "fine print". Here's a *partial* list: MicroVAX 3100 (30's, 40s, 80s and 90s) VaxStation 3100 (I think) DEC Rainbow 100 (in it's original box...somewhat worse for wear) Printer for DEC Rainbow Documentation for DEC Rainbow HP Apollo (don't know more than that) 12-15 RL01/RL02 drives. I don't know the condition. Some look good, others, well not. 4+ RK05 drives. Most of these don't work (from my notes) but shouldn't require a lot 5-6 Fujitsu Eagle drives. Don't know the condition but they look OK. 2-3 MicroVAX in BA23s Sun IPX (not sure how many) Sun IPC (not sure how many) Sun SS10 (1 or 2) Sun SS20 (1 or 2) Sun Ultra 5 Sun Ultra 10 DEC PDP-8/a SWTPC (no idea what's in the case) 4-5 DECWriter IIIs 2-3 KSR/ASR33s of various types and conditions Micro PDP11s in various cases. Some are in BA23s, some are OEM cases 3-4 MicroVAXs in BA123 3-4 ADM3a. Don't know the condition 4-5 VT100. Don't know how well they work 4+ PDP-11 11/34s (a couple are still in racks) 2+ PDP-11 11/44s a few PDP-11 11/84s (I know one is complete. I'm not sure what state the others are) 1-2 PDP-11 11/24s 1-2 PDP-11 11/05 or 11/10 (these are minimal) a few BA11F chassis (some empty some full of backplanes full of cards) TU80 tape drive TU81+ tape drive 3-4 Kennedy tape drives (some in racks) 5-6 RX01/RX02 dual floppy drives Contact me off-list.

Selenar Graphics II LA-36

by rickb＠bensene.com

I have powered up the LA36 with the Selenar Graphics board in it, and >from the information kindly obtained by list members (Byte Magazine article about the Selenar Graphics II), I have been able to verify that the unit indeed works. The graphics mode works, and all of the other features documented in the Byte article seem to function properly. The issue that I've found is that only 5 of the 7 print pins are working. Numbered with the top pin as number 1, it is the 3rd and 6th pins that are either not firing at all, or are jammed such that they can't come forward enough to make an impression. I can't find a service manual for this unit online anywhere, so I'm wondering what the best approach to diagnosis would be. I do have schematics, but since the unit has a Selenar Graphics II logic board, I'm not sure how well the schematics will help. Since the Selenar board replaces the stock logic board, I can safely assume that it retains the pinouts for the connectors that go from it to the power board that has the drivers for the solenoids in the printhead. So, I can probably scope out the drivers to see if they are firing on pin 3 and 6 when printing characters that require those dots, which I will do when I have time, but I'm wondering the next step would be if I find that there are firing pulses coming out of the pin drivers for pin 3 and pin 6. Obviously, if I find that the pulses aren't being generated, then I have to dig into the solenoid drivers for these pins and figure out what has failed and fix it. If I find that the solenoid drivers are OK, then what should be done next? Would it be to remove the printhead and do what Tony suggested, which would be to use a bench power supply (I have a good Tektronix bench supply does truly does deliver 0.00V) to try to fire the solenoids to see if they are gummed up? If so, how do I go about removing the printhead to do this? Just from looking at things, it looks like I would have to do a lot of disassembly to get the printhead out of there. Does the printhead come off separately from the carriage that it rides on, or do I have to remove the whole carriage assembly? Any guidance would be most appreciated. Thanks, Rick Bensene

Core Memory Failure Modes

by derschjo＠gmail.com

Hi all -- Last night I finally got the Imlac working to the point where I can run programs more advanced than a light chaser, and I'm using my newfound abilities to take a closer look at the functionality of the system's core memory. This is a Dataram "DR-101" system (Docs are on Bitsavers now), 8KW of 16-bit words and when I got the Imlac all the socketed ICs on the control PCB were extremely corroded. I outright replaced the corroded ICs (most of them were too far gone to deal with and the rest were marginal) cleaned the sockets, and at this point it's fairly functional. I whipped up a simple program to walk through memory and test every location (by writing / reading back all possible 16-bit values at every location). The results are mostly positive, aside from a small addressing issue (the upper two MSBs of the address from the CPU are apparently being ignored by the memory's addressing logic so I get 2K repeated over and over again). What I did find was that most of the memory I'm currently able to test (the repeated 2K) tests out fine. However, there are a few addresses in the 210-240 address range that either have dead bits or behave sporadically, and there's a single bit near the top of memory that's stuck off. The failures are 100% consistent (even the sporadic failures always show up at the same addresses) and reproduce identically if the system is "cold" or has had time to warm up for awhile. I'm not sure whether to suspect calibration/alignment issues here -- I would expect failures to be more widespread or have repeating patterns of some sort if the system was out of alignment. I'm tending to think that the core plane may actually be damaged in places, which would be very unfortunate. However, I don't have a lot of experience in diagnosing core memory failures; so far I've been fortunate -- the systems I have that use core memory have not had issues with the memory. Anyone with more experience here have any suggestions? Thanks as always (and yes, I'm still working on the 8/L current loop stuff I've just been distracted because apparently I have no attention span and thanks again for all the help there :)), - Josh

Forsale: TeleVideo Items.

by me＠GarrettMeiers.com

I found homes for some of my TeleVideo systems at VCFMW, but still have a lot left. In getting the ones I sold ready, I ended up finding quite a few systems that were not functioning. So, I will be testing every system this week to find out the ones that have issues, and will know what I have that works/doesn't work. If anyone is interested either in working systems, or possibly systems with issues, let me know. Some of you have expressed interest already, but please feel free to let me know again if you are interested. I'd love to find buyers locally on CCTALK, but need to get these out of the garage, so Craigslist, and then eBay, are my next steps. Here is a list of what I have currently: https://docs.google.com/spreadsheet/pub?key=0Ahk4_RQTUNcYdFpTOFQ3RFdMQ0FocE… Thanks, Garrett Meiers www.linkedin.com/in/theunixguy

old CAD workstation used for MEDUSA

by stefan.skoglund＠agj.net

Hello In the mid 80ies i was at school in Sk?vde Sweden. At that time that school had a PRIME 9955 system together with the normal serial terminals and also a fair number of specialist CAD workstations. The CAD stations was used for MEDUSA and another Electronic CAD package (we did PCB designs in that system.) I have two questions (because of a foggy memory): what was the maker of the work stations (or who could they be) ? and could someone name a number of pcb design programs for PrimOS ?

Reviving elderly BBC Micros

by lproven＠gmail.com

So I have recently been given half a dozen Acorns - one Model A, 4 Model B+ with 64K and one 128K B+. I'm going to donate the Model A, at least, to TNMOC at Bletchley, but I'd like to keep at least one for myself. The thing is, whereas I wouldn't just turn on a 1980s business computer with multiple moving parts, the donations chap at TNMOC has put The Fear into me by sternly warning me Not To Turn Any Of Them On, because They Will Blow Up. So, how does one go about testing a mucky old Beeb that's not been on in 25y or something & has been stored in a dusty attic? Give it a good clean, I guess, but can one hook one to a PC PSU and test its internal PSU in isolation? -- Liam Proven ? Profile: http://lproven.livejournal.com/profile Email: lproven at cix.co.uk ?

KYBE MLC400 tape cleaner -- parting out

by bub7734＠yahoo.com

I have a marginally functional KYBE MLC400 tape cleaner that I'm going to be recycling.? It is almost functional, but one of the cleaning tissue spool motors is missing and the other three motors appear to be non-functional and requiring rebuilding. This thing is big and heavy, at least 70 lbs.? I don't have materials for crating or boxing it for shipping. I'm going to be recycling the unit.? But before I do that, I'll make any parts on the machine available FFS. If anyone has an MLC400 in need of parts, contact me ASAP.? My next recycling pick-up is in a week, and I intend to gut it of any useful parts for hobbies so let me know if you need anything for your unit. Alternatively, anyone in the Minneapolis area can pick up the entire unit. -scott

Help identifying a 9316B ROM

by ethan.dicks＠gmail.com

Hi, All, While tidying up, I ran across the following.. 9316B-4504 KA53895 [GI]7851 I was unable to find anything about this specific part via Google, but I know it's a 9316, made 51st week of 1978. I suspect it's a character generator ROM. Might anyone have a list of those? I can probably toss it in an EPROM programmer and dump it out (once I figure out what the chip select lines are expecting), but just a line >from a catalog page or a note from a schematic could save a bit of fiddling. Thanks, -ethan

introducing the Media Archaeology Lab

by lori.emerson＠gmail.com

Hello all, I wanted to move from lurker to...whatever the opposite is by introducing myself and the Media Archaeology Lab (MAL) I run. I'm thrilled to discover your listserv as I'm learning a lot just by reading your posts and I think many of you will be interested in the MAL. http://mediaarchaeologylab.com Founded in 2009 and housed on the University of Colorado at Boulder campus, the Media Archaeology Lab houses obsolete media from the early twentieth century to the twenty-first century for hands-on research, teaching, and research creation. I've come to see that the MAL is a remarkable configurable conceptual object that, depending on how you approach it, houses items for research and teaching, items that actually generate research; is a site for artistic interventions, experiments, projects; is an archive for media objects; is an archive for original works of digital art/literature along with their original platforms. It belongs equally in literature departments, art departments, media studies departments, history of technology programs, computer science departments, libraries and archives. The MAL is a "living archive" in the sense that, other than our stockpile of spare parts, everything in the lab functions and is meant to be turned on and used for tinkering, play, teaching, and research. It is also living in the sense that it is an ongoing, DIY project primarily run by and for the self-taught that continues to grow and change with every new influx of participants. In fact, one of the strengths of the lab is that there are almost no precedents for it and no clearly established set of best practices. The MAL's strongest collection is its historically important personal computers from the late 1970s through the 80s and 90s - computers such as the Apple II, Apple Lisa, and Apple Macintosh, as well as many early works of digital art/literature from the early 80s through the late 90s. If you'd like to know more about the MAL or if you'd like to donate, please visit our site: http://mediaarchaeologylab.com yours, Lori --- Lori Emerson Assistant Professor | Director, Media Archaeology Lab Department of English, University of Colorado at Boulder Hellems 101, 226 UCB, Boulder, CO 80309-0226 loriemerson.net | mediaarchaeologylab.com

Data General One, EL backilght version

by shadoooo＠gmail.com

Hello. I have two similar Data General One, one with fixed disk, the other is the two-floppy version. Both came with no manual or disk unfortunately. Trying key combinations, I found the CMD-+ and CMD-- way to turn on and off the EL backlight, while CMD-LARROW and CMD-LARROW changes contrast. Any other useful key combination? At power on, the two floppy version doesn't boot (no floppy disks), but it shows a BIOS menu where we could format floppies and use the machine as serial terminal. Nice! I tried to format a floppy (720k or 1.44M) on both floppy, but with no luck, it doesn't work for some reason... :( No way to boot the machine from a previously written 720k disk. I don't understand what the problem could be. Any similar case anybody? The fixed disk version boots nicely the MSDOS still installed on the HD. It seems to work fine. This is a customized version for Allen-Bradley, it has also a big D-sub connector with three rows of pins on the back. It has also a memory expansion in the back slot, with a total of 640K+896K detected at boot (1.5MB total). No way to enter the BIOS menu however... maybe it's missing in this version? Anybody have a scan of the manuals or images of floppy? Thanks Andrea

DEC TSZ07 ..relabeled Cipher 9 Track tape?

Hi, I know that the DEC TSZ07 9 Track drive is made by Cipher. Does someone here know if there is a near equivalent Cipher Model? The Cause of my Question ist, that I think I have a ugly fault in the PSU, when the Drive is in standby, some parts of the circuit are overheating. Look here for pictures: http://www.tiffe.de/Robotron/TSZ07/ I've repaired the PCB but the parts are still getting hot in standby, because standby no fan is running.. Since the Technical Manual of the TSZ07 contains no schematics, I've looking for the equivalent Cipher model to find schematics of that PSU... Kind Regards, Holm -- Technik Service u.

Hi! I have a few remaining "cats and dogs" PCBs looking for a good home. If anyone is looking for the following: 1 ECB ColorVDU (last one!) 2 ECB 6x0x host processor (2 left) 1 ECB MSX cartridge reader (1 left, probably will get some more interest now that N8 PCBs are available) 2 ECB SCG (2 left) (Sound, Sprites, and Color Graphics for TMS9918 video and AY-3-8910 sound) 1 ECB bus extender (1 left) very handy for those with an ECB card cage 3 ECB Cassette interface (3 left!) Kansas City Standard -- read those old data cassette tapes before they crumble to dust! 1 S-100 Parallel IO (1 left!) These are all good boards to build. It would be nice to move some of these which have been sitting here on a shelf all sad and lonesome. They'd like to find a new home on some builders workbench! Thanks and have a nice day!

Looking for DECtalk DTC-01 v1.8 and other non-v2.0 firmware roms

by jgevaryahu＠gmail.com

I know that the original vt240-molded-case DTC-01-AA DECtalk had multiple firmware versions, but all units I've ever seen have had the v2.0 (i.e. the final) firmware installed. I know at least version 1.8 existed in older units, and was wondering if anyone here has a DECtalk DTC-01 with firmware 1.8 (or any version other than 2.0) in it. It should speak "Dectalk version x.x is running" when powered up. Bill G. had or used to have a v1.8 unit, but I can't manage to get in contact with him and I don't know if he still has it. At least one other person on usenet had a v1.8 unit where the eproms all bitrotted to blank after a while. P.S. I'm also hunting for DECtalk DTC-03 (decmodem-rackmount) firmware versions; there are at least three, maybe as many as six different firmware versions for those cards. -- Jonathan Gevaryahu jgevaryahu at gmail.com jgevaryahu at hotmail.com

accepting S-100 RAM&ROM pre-orders

by LYNCHAJ＠YAHOO.COM

Hi! Now that the S-100 6502 CPU V2 and S-100 Parallel IO PCBs are winding down it is time to get the next PCB order rolling. We need 20 PCB pre-orders so I can make a manufacturing order. The S-100 RAM&ROM board is ready for "production". If you would like to get one or more of these exciting new S-100 memory CPU boards please do the new usual pre-order. I will set aside your board so you get them as soon as they arrive. Here is a link to S100computers.com website with information on the new board. Basically it is an 8 bit/16 bit fusion of the S-100 4MB SRAM board and S-100 EPROM board which addresses major issues with each board. Overall this is a much better and more flexible memory board that should be a general solution for almost all your S-100 memory board needs. http://www.s100computers.com/My%20System%20Pages/RAM&ROM%20Board/RAM&PROM%20 Board.htm The PCBs will be $20 each as per the usual arrangement. Shipping in the US is $3 for a single PCB and $2 for each additional PCB. Shipping internationally is $10 for a single PCB and $3 for each additional PCB. This is for the bare basics USPS first class postage with no tracking or insurance. The builder assumes all risk of delivery as per usual arrangement. Please send a PayPal to LYNCHAJ at YAHOO.COM and I will reserve your board(s). Thanks and have a nice day! Andrew Lynch

Collection to sell

by jlw＠jlw.com

There's a chance that the Sun 4/260 in the collection was once mine. I had it between about 1993 and 1997, in Mountain View, CA. I eventually grew tired of the noise and bulk sitting in the dining room, and offered it to interested parties. Barry came by to pick it up, along with the Fuji tape drive, and a loose SMD drive or two, plus the 4119 color monitor and about 50 feet x5 coax to put the monitor far away. He had an online museum that he was going to put it in, somewhere in the Santa Cruz mountains. I don't see the SMD controller in those 4/260 pictures though, and I didn't take the SMD pedestal when I got the whole machine in a fire sale for five bucks. I'm pretty sure I don't need it back. :-)

Disk Format for Rockwell System 65?

by marvin＠west.net

I'm cleaning house (again/still) and found two disks in the Rockwell System 65 I have. So far, I have found no docs/schematics on this machine. If they are the system boot disks, I'd like to get them archived with a disk image to help others who might have one of these systems. The drives themselves are Shugart Model 400 floppy disk drives. Does anyone know what it takes to read the data and/or make a disk image on these disks?

AIX for PS/2?

by jon＠jonworld.com

Some posting on another list gave me a hankering for wanting to try to get the old AIX for x86/PS2 systems running in a VM. I have two old Floppy disks (3.5") labelled AIX BOOT and AIX INSTALL ... the BOOT disk boots but doesn't give an option for installing from the install disk. The install disk doesn't really seem to boot. I assume there are more than just these two disks to get the OS running. Anyone out there have a source? -- -Jon Jonathan Katz, Indianapolis, IN.

Free Sun items for Sun 2 and Sun 3

by silvercreekvalley＠yahoo.com

Clearing my storage unit and have a few bits and pieces of Sun stuff if anyone is interested. All items are not tested, so for parts only, and they are free but collection only. I have some pictures. Sun 3/60 - seems complete with colour frame buffer and memory Sun 3/80 - case, motherboard, floppy drive and PSU only (no memory or HD) Sun 3/80 - case only Sun 2 monitor on swivel pedestal. This looks to be mono ECL but serial number is hard to read so not sure. Hard to find these days. A large CPU board - I think from a SPARCserver of some kind (501-2055), it is fully populated with memory, has an SBUS card (frame buffer possibly), and two CPU modules fitted. A boxed Sun keyboard (probably Sun sparcstation era). Collection from South bay area (near San Jose, CA). All items free. Prefer someone to take everything in one go. Email me if interested.

WTB Apple 2 Serial Card?

by jon＠jonworld.com

All, The subject says it all. I have a ton of data on an old Apple 2 I'd like to get off of it. I tried ADTPro using the audio/tape ports on an Apple ][e but I could never get it dialed-in correctly. In all honesty, I just want the ASCII content out of a bunch of word processing files; I don't need to transfer disk images. I figure if I can "print" those documents over a serial port, through a null-modem cable and into another system I can capture the ASCII as a text file and be done with it. Does anyone have one laying around that could be put to good use? Thank you! -- -Jon Jonathan Katz, Indianapolis, IN.

The large number of serial ports is unusual in a Z80 as with 64K memory there's a limit to what you're going to talk to. I wonder if MP/M was available. that would be terrific. If you're using a terminal I would use a straight-through cable rather than the null modem. A computer to terminal set up is DCE to DTE in the eyes of RS-232 and so no cross overs should be needed.

Sperry 3070-08 PC

by jules.richardson99＠gmail.com

A long shot, but does anyone happen to know the [external] DIP switch settings for a Sperry 3070-08 PC (a bit of googling suggests it's a Sperry "HT")? I think I may have accidentally flipped some of the ones on the back of mine - the system's now stuck in a repeated-beep loop with no display init, so possibly it's looking for RAM where there isn't any (OTOH, it just moved locations, so I'll re-seat boards etc. just in case - but I'm reasonably sure that I caught the switches at one point, so it'd be useful to know where they should be set at for my particular config). cheers Jules

N8 PCBs are here

by LYNCHAJ＠YAHOO.COM

Hi! Good news! I ordered a batch of the N8 PCBs. The N8 is a group project design from the N8VEM home brew computing project. I received some questions about the N8 so I am sending this bit of background on the project. The N8 project is on the N8VEM wiki and mailing list. I had previously offered the PCBs there and here on VCF directly to builders. However now I am also putting them up on VCGM to help get the word out a little better. The N8 is intended to be a "home brew" style computer in the style of early 1980's all-in-one home computers with a usable set of features such as color graphics, audio, an assortment of mass storage options, a variety of ports, etc. Although a bus expansion is supported no additional boards are required. The N8 is designed so builders can assemble it themselves using common tools such as basic soldering iron, VOM, etc. It is a simple two-layer board construction using all commonly available plated-through-hole (DIP and PLCC) components without requiring any SMT skills, programmable logic devices, etc. A quick summary of the N8 features: Processor & memory: Z8S180 CPU (Z80 compatible, 33MHz max), with 1MB SRAM and 512K Flash boot ROM (in-circuit reprogrammable) Primary Interface: Color video (TMS9918A), Sound generator (AY-3-8910), and PS/2 keyboard and mouse ports Mass storage: IDE drives (including CF adapter) port, Floppy drives port (1.44MB 3.5"), and SD socket Expansion I/O: Two Serial ports, Parallel Printer port, Two MSX compatible Joystick ports, RTC w/NVRAM (configuration data), RS-485 networking port Various diagnostic LEDs, "front panel" status indicators, buttons, with optional debugging hex display and keyboard (DSKY) A builder has also designed an enclosure for the N8 http://n8vem-sbc.pbworks.com/w/file/52623834/N8%20Case%20Construction.zip Photos of prototype enclosure http://groups.google.com/group/n8vem/browse_thread/thread/e7cf446f1e33760c# There is an MSX BIOS ROM image (in development) here http://groups.google.com/group/n8vem/browse_thread/thread/c880ea6aa13ccff7 There is a Z-System ROM image (in development) here http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder?m=RomWBW The PCBs should be here in mid to late Jun 2012. http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder?m=N8-final Click to view PLOTS of PCB https://www.freedfm.com/freedfm/0011697403232210/results/plots.htm The N8 PCBs will be the usual $20 per PCB with $2 shipping in the US and $5 elsewhere. I am offering the PCB only. No assembled units as this is for home brew computers. Most of the chips are available through Jameco, Digikey, etc. Some of the specialty chips like the AY-3-8910 and TMS9918 would have to come from eBay, UTSOURCE, Unicorn Electronics, etc unless you have those on hand. I don't know what the final assembly cost would be and it would depend a lot on how you build it. Styles differ dramatically and depending on your supply of parts could vary widely. Several builders have working units on the N8VEM mailing list so I suppose you could ask them or look up costs on the parts list/BOM from the wiki. Since it is an all-in-one design rather than multiple boards there are a *lot* of parts stuffed into the 60 square inches of PCB. However there is only one PCB. There is some efficiency gained by stuffing everything into a single board rather than spreading out over several boards on an ECB backplane. The N8 is a bit like the P112 SBC except it is all DIP/PLCC (PTH PCB assembly, no required SMT) and has richer IO options like video and sound. It is larger though so it is a bit of a trade-off. Thanks and have a nice day! Andrew Lynch PS if you want to see detailed close up photos of the N8 prototype in its enclosure then download the large ZIP file above on the N8 Case Construction. Great photos of the system (credit to Dan)

In anticipation of pulling and replacing 1/3 the DRAMs on this board, I tried the trick of a dry-fit piggyback with known good chips on the locations marked as bad. I can report 100% success. I stuck 6 new chips on the 6 bad chips and got past the Sad Mac. In the light of the several reports I found on support forums, all I can imagine is that if these people replaced their bad RAM chips, either they misread the conversion table and replaced the wrong chips, they damaged the chips or the mainboard traces during the repair process, or they just have a bunch of cold, dry solder joints. Present state: machine gives "bong" when turning on (it always did), usual screep wipe happens, then the "[?]" disk icon flashes. I have one 400K drive, an OA-D34V-22, and (for now), Rev A ROMs. This combination does not work. It tries to read disk, ejects it, then asks for another one. I already have the -B ROM images and just need to burn a pair of 27256s since that's an easier path than locating a working, original revision OA-D34V drive mech. On the OA-D34V-22 I do have, it did require removing petrified grease from the old eject mechanism. I have some white lithium grease I'm contemplating using unless there is some magic grease the job requires. So the repair is nearly complete. Bad trace/repair damage found/fixed, bad RAMs identified and tested, and a couple items to complete to finish the job. -ethan

S-100 6502 CPU V2 PCBs have arrived!

by LYNCHAJ＠YAHOO.COM

Hi! These PCBs are almost gone and there are only two left. I am keeping one for myself so if you want to get one please do it soon.

Shipping in the US is $3 for a single PCB and $2 for each additional PCB. Shipping internationally is $10 for a single PCB and $3 for each additional PCB. This is for the bare basics USPS first class postage with no tracking or insurance. The builder assumes all risk of delivery as per usual arrangement. Please send a PayPal to LYNCHAJ at YAHOO.COM and I will send your board(s) right away! Please contact me if you have any questions. Thanks and have a nice day! Andrew Lynch

Does anyone have any information about this CIT-467 terminal?

by me＠GarrettMeiers.com

I have a C.Itoh CIT-467 Terminal. I've been able to find almost nothing about it on the Intrawebz. Was hoping someone might recognize it, or could point me in the right direction about finding a manual for it, or knowing what it's capabilities are (besides it obviously being a serial terminal). I've not even turned it on yet, wanting to find some more information about it first. I don't have a termcap entry for it, or anything close to it, on a few Linux systems I've checked. Any help would be appreciated! https://www.dropbox.com/sh/rlb1j1jcqqwffrf/t-O8t_8_L4 T ?hanks, ? Garrett Meiers www.linkedin.com/in/theunixguy

Hardware parsing of BASIC?

by derschjo＠gmail.com

So Iwas taking a closer look at the HP 1351A "Graphics Generator" I have. It's currently in operable condition, except that it won't draw text (apparently there's something wrong with the character generator, the :TX commands do nothing at all). I was surprised to discover that the 1351 (c. 1981) doesn't containa microprocessor or microcontroller of any kind -- all parsing of the command language it supports is done in hardware (TTL). (The service manual contains this gem: "The 1351A only accepts commands listed in this manual and in the Operating and Programming manual. Any others, especially those mentioned above will 'lock up' the 1351A such that it will have to be re-initialized...") At any rate, this reminded me of something that I'm prettysure I read here on cctalk years back, but I can't seem to find any reference toit anywhere; there was a computer designed at some university that ran an interpreted language (I'm pretty sure it was BASIC), on the metal-- that is, much like the 1351A and its vector description language, this machine's hardware parsed BASIC program text and executed it directly, rather than implementing some machine language. Does this ring any bells, or am I insane? (It's quite possible that both of these things are true...) - Josh

NEC DKU 743 Disk drive?

by shadoooo＠gmail.com

Hello Holm, I hope you find some part to repair your tape system! If the NEC disks you found have SMD interface (two flat cables, one is wider) and you don't need it, I would be glad to buy it. Thanks Andrea
