Kaypro System disks?

by brain＠jbrain.com

I have been fortunate to acquire a Kaypro system that appears to be in great condition and looks to work. It looks exactly like this: http://www.computermuseum.li/Testpage/Kaypro-I-Micro.htm Thus, it says Kaypro 1 on the artwork Still, the sticker on the rear says Kaypro 2, so I'm confused. In any event, I have no system disks for it (There is a slight possibility they are part of the stash with which the Kaypro was bundled, but it's 100 sq ft of stuff). Thus, I'm wondering if there is a kind soul who might be able to ship me a set of disks. (I'll pay shipping, of course). I also am the proud owner of 2 Obsorne machines (one works, the other seems to have drive issues. They are the redesigned units, but (as I suspected) the systems disks won't work on the Kaypro.

CMD CQD-220 ROM fixes

by fraveydank＠gmail.com

A while back, I mentioned that I'd found and potentially fixed the "bricking" problem with the CQD-220. To recap, for those that werent following, the problem lies in the code for the on-board 8086 when you set the number of both disks and tapes to zero. The 8086, during its routine to load the values from the EEPROM, loads the total number of disks and tapes and executes a loop with a counter predecrement; if the counter is loaded as 0, it effectively runs through the loop 256 times instead of 7 (the max), which spins out of control and blows away some RAM somewhere before crashing. Fortunately, through a compiler bug or some such, there are 5 bytes available from a totally redundant instruction (loading a value into a register where the same value is already loaded) in just the right place to test the total number of devices and jump to the "uninitialized device table in EEPROM" section of the routine if it is zero. With one byte to spare! (good thing NOP is only a byte in 8086) This applies to the A7A revision of the ROM, anyway; I haven't gotten to the A8 version yet, though I know it exhibits the same bug. Hopefully it also has the same redundant instruction. In any case, I should be able to find and fix it quickly once I have the time, because I know where to look. So, here's the thing; I've finally gotten the time to test the fixed ROM image (was temporarily short of 27256 chips, but that's been resolved) and I'd like to get the fixed images somewhere they'll be easy to find if anyone else runs into the same problem (this took me over a year of sporadic attention to fix). Does anyone know where I should post this? There's my own website, which is really not a thing anymore, but there are probably lots of places Google is more likely to find. Also, are there copyright implications to consider? I know CMD is long gone, but I still worry about these things. Last thing: does anyone know the difference between the A7A ROM and the A8? I've not found anything different; I assume it's probably an obscure bugfix. The images are only 64K total, so I shouldn't imagine they'll be bandwidth intensive. - Dave

Mac Performa 6400/200VEE

by jules.richardson99＠gmail.com

I found a Mac Performa 6400/200VEE at the dump today, but no keyboard / rodent / display. It seems to have 128MB of RAM installed, along with a video I/O board (the 'VEE' bit, I suppose) and Ethernet board. The downside is that there's some significant battery corrosion toward the bottom of the system board PCB. I'll try some vinegar and see how it goes, but obviously it doesn't make sense to source a keyboard, mouse and display from anywhere if the system's toast. 1) Is it possible to wire the 15-pin monitor connector up to a PC's VGA monitor? Or, 2) Can I hook the composite out on the video I/O board up to a TV and expect to be able to see something at boot time? (I'm not sure if that board's only initialized after the system's booted) Done with hard disk disconnected, obviously - but will the system even output anything to the display with no keyboard or mouse present? cheers Jules

I haven't been able to quickly find a reference picture for the variable density (sometimes called "Western Electric") system, but it consists of density gradients along the sound track (think "analogue bar code"). Magnetic sound track gives itself away as a strip of brownish color (like audio cassette tape) that is laminated onto the film along one edge. Sometimes there is a second "balance" strip along the other edge so the film will spool up more evenly. > After processing this was read using a lamp and photocell, the signal > from the latter was the original audio.

All three systems were available for 16mm film, my Siemens System 2000 projector would be capable of playing them all back. There is a switch at the amplifier (in the projector base) to select between optical and magnetic audio and a knob on the optical reading head to select width or density modulation. > Super-8 8mm film could have a magnetic soundtrack (I have never heard of > opticla sound on such films).

Projectors and cameras obviously could not record sound in this system, but optical sound package movies became briefly popular, particularly in Europe (mainly because they were cheaper to produce - though the projectors cost more). Although the optical sound should have been inferior in quality to magnetic sound (running at 3.6 inches per second for 24 frames per second), in practice it was often much better, largely because packaged movie magnetic sound was often poorly recorded." No mention of audio tracks in any form in the Regular-8 article however. Arno

KA655 SLU without proper bulkhead

by fraveydank＠gmail.com

Hey all, I recently acquired a KA655-AA (MicroVAX 3800/3900 CPU) and some appropriate RAM, and I'm having trouble grokking the console SLU output. If I'm reading the docs correctly (and I have to go all the way back to the KA630 docs to find the proper switch polarity), if I'm running it without a bulkhead attached at all, the serial speed should be 300 baud. When my terminal is running at 300, 8 bit, no parity, 1 stop bit, I get some garbage on screen but not much more. Am I missing something? Do I need to do some magic with the front panel ports to make it cooperate? I'm using a DB25 serial cable that I've been using on my KDF11-B CPU board with no trouble; if I look at the docs, it looks like it should be fine assuming I can let DTR float (it's unused in my cable, since it's an external clock pin on the KDF11-B). I can also see the LEDs on the spine of the CPU counting down, though I didn't watch for long enough to see if they ever got to zero. As far as I know, the memory is connected OK and works, though I assume I don't really need that if I just want to see a console prompt. I'm using a very short (~3") 50-pin SCSI ribbon cable, which I assume is OK. And it's an MS650-BA, which the KA655 manual specifically calls out, because the -AA is too slow. - Dave

DECnet MOP download file formats??

by bob＠jfcl.com

I've got a little "satellite" PDP-11/23 with just a CPU, memory , some serial ports and a BDV11 bootstrap card. One of the serial ports is connected to a bigger PDP-11 running RSX-11M+ and DECnet-11M. My goal is to use the DECnet MOP bootstrap built into the BDV11 to download a "bare metal" application from the RSX system on the bigger -11. So far, so good. After a little twiddling with the DECnet configuration I've got it so that I can trigger the BDV11 boot and the host will download the secondary and tertiary loaders to the satellite. Amazing :-) Now the problem is for me to write some application for the tertiary loader to download. Writing a PDP-11 assembly program is not an issue for me, and I've got MACRO-11 and TKB on the host system, but I don't know exactly what DECnet wants. How is the application system image supposed to be made? What's the file format that DECnet wants to download? It's probably made with TKB in some way, but what are the proper TKB options? Where (in memory) does it get loaded on the satellite? What address does it start execution at ? Is the MMU turned on? Is the I/O page mapped? Are any useful values (e.g. a pointer to a valid stack, the address of the download device CSR, etc) passed in the registers? So many questions ! Can anybody point me to documentation on this, or an example of a little program that gets downloaded via DECnet MOP? In the olden days, people probably would have generated an RSX-11S system and downloaded that, but I don't have an 11S kit so that's not an option. Thanks, Bob Armstrong

Moving gear

by ggs＠shiresoft.com

While this is mainly for folks in the Bay Area, I'm posting this for informational purposes and if anyone happens to be in the Bay Area to help, I'd appreciate it. As many of you know, a couple of years ago I moved out of my shop and put everything into storage. It dawned on me that what I was paying in storage fees would finance a mortgage (ouch!). After a brutal 6 month search, my wife and I found a property that met all (ok almost all) of our criteria. One of the fundamental criteria (which nixed a number of houses that we liked) was that there be a "shop" on the property. This one does. The main level of the shop is 3 rooms totaling ~1000sq ft. Then there's the upstairs which is another ~400sq ft (with 6' head room) and finally the "basement" which is ~250sq ft (with 5' head room). I'll post a link to pictures once I put them up. Remember, this is the shop. The house is *spectacular* and I'll cover that if folks are interested but I'm not going into detail here since it's off topic. This is our retirement property (yes we're getting to that age unfortunately) and is about 180 miles from our current home. On the plus side, the property is almost 10 acres. I spent this past weekend moving ~150 "totes" from storage up to the new shop. I barely made a dent in my storage units. I need help in moving all of this stuff. Much of it is going up to the new place. However, there is a large quantity of stuff that I've acquired that came along for the ride as I was acquiring other stuff. Some of what will *not* be going (more will follow as I dig out more stuff): - Sun gear. I have a number of IPX's, LX's, SS2's, Ultra5's. I don't know the status of them at this point but many of them (especially the Ultra5's) are in great shape and I expect them to be fully functional. - microVAX. I have fair number of these. From pizza box styles to BA123s. - Q-bus based 11s. I have a number of these, but I didn't run across them this weekend so I can't give a complete inventory - 11/34s. I have 2-3 of these. They're pretty well stuffed. I haven't actually run these and they're still in the rack(s). Here are the rules: - I will *not* ship. I'm under serious time pressure and I have *no* time to pack and ship stuff. - I will *not* look for specific stuff. I'm basically a packing robot at this point. I'm operating on a binary decision: go or not. I'm not looking at stuff in detail, there's no time. - You come and help me move, you get to pick stuff that you want (that I'm not taking). - If you don't want to help move, you will be expected to pay a "nominal" value for the item. - If you come to help, I expect you to work. I don't have time to waste on jaw boning. - If you want stuff, I expect you to come...look, (pay), take and leave. - Tell me your availability. I'm doing this on weekends. I will *not* be doing any of this during the week. My "real" job consumes all of that time. Sorry to be a bit blunt but I'm in a bit of a rush and need to get stuff moved. Ideally, everything will be moved by 6/1. Oh, and for those of you who might ask, anything that's left will be sent to WeirdStuff. If you're interested, please contact me off-list. TTFN - Guy

TM100 anywhere? (Kaypro drive woes)

by brain＠jbrain.com

Anyone got a working TM100 in their spare parts box? Or, alternatively, anyone up to diagnose a dead TM100 for a fee? The K4+88 needs one. It drags the PSU down completely when plugged in, and the mech won't read a disk with a known good controller. Also, the drives in the K4 (half height, I forgot to write down the model number) run but are out of alignment. If someone is up to aligning them, I'd pay for the efforts.

Last chance on Local Pickup machines in Flushing MI

by dm561＠torfree.net

----- Original Message ----- Date: Sun, 21 Apr 2013 01:14:49 +0000 From: "Sam O'nella" <barythrin at gmail.com> > The point of whoever posted the complaint originally was more of the lines > of "300$ or it goes to goodwill". I got the point the first time, thanks; he could also have read it as: "I need to get rid of the following items and would like $xxx; if no one is prepared to make an offer that's worth my while I'll donate them to charity." As Richard says, if you want 'em and are prepared to pick them up, make an offer; Landon's not a committed generous collector, he's a dealer with a dubious rep, and IMO the prices are actually reasonable by ebay standards. If not, move on; don't waste time bitching because you don't like Landon and his prices or Goodwill's policies, think he *should* be prepared to ship and/or break them down for parts, etc. etc. They're PCs and Macs, not Kenbaks or PDP-6s... But bitching at/about other people is what this list is largely about these days, alas...

SDSX.SYS in RT-11

by jhfinedp3k＠compsys.to

Has anyone been able to successfully use SDSX.SYS under a Mapped RT-11 Monitor? Or does it have a bug and if so, does anyone have a fix? For as long as I can remember, I have used SDX.SYS (= SDHX.SYS) to debug my programs under RT-11. Unfortunately, the SDHX.SYS variant freezes everything in RT-11 (all jobs, device drivers, monitor and even the clock) when the program is stopped at a breakpoint. Note that DEC supplies two variants of SDX.SYS which execute under Mapped RT-11 Monitors: (a) SDHX.SYS which is called HARD (b) SDSX.SYS which is called SOFT In both cases, the file of the chosen variant MUST be copied to SDX.SYS before that variant can be used. Obviously, only one variant can be used at a time. Very recently, I had the occasion to link VDT.OBJ (the ODT variant modified into VDT) into my program and I found that other jobs were no longer frozen. I hoped that SDSX.SYS => SDX.SYS might produce the same result. However, not only does SDSX.SYS not perform in that manner, but as soon as I attempt to activate other jobs (almost always, those other jobs are KED variants executing as system jobs which display the listing for the potion of the program which is being debugged) which are in an IOWAIT state (holding for keyboard input), RT-11 usually crashes immediately, especially when the breakpoint is in the RT-11 monitor. Does anyone have any experience with SDSX.SYS which is different, specifically when SDSX.SYS actually works and still allows other jobs to execute at the same time while one job is stopped at a breakpoint under SDSX.SYS and the other jobs are KED variants which are displaying a listing of the program which is being debugged. While SDHX.SYS works perfectly, since it freezes everything when the program is stopped at a breakpoint, I had hoped that SDSX.SYS would allow the other jobs to move to other portions of the listing as other portions of the code were being executed, often instruction by instruction. In case this information is helpful, the other system jobs which are executing KED variants have opened the listing file in READ ONLY / INSPECT mode, and no other file requests are being executed. I had somehow hoped that if VDT could execute correctly but still allow other jobs to continue, that SDSX.SYS might also allow that as well. Can anyone help or at least comment? Am I doing anything wrong? Is there a bug in SDSX.SYS which no one else has found? While I am using a Mapped Monitor which has Multi-Terminal support, the same problem is present when the DEC distributed monitor, RT11XM.SYS without Multi-Terminal support is used. While <CTRL/X> must be used with the same terminal to re-activate a system job, when SDSX.SYS is used, the same problem occurs. So does SDSX.SYS have a bug and if so, does anyone have a fix?

Wanted: DEC VT100

by rsnodgrass＠gmail.com

I am looking for a DEC VT100, or possibly VT102, to add to my computer collection. I spent many years early on programming on VT100/102 series connected to VAX 11/750 and VAX 4000. I've wanted to have one as my terminal for quite some time. Does anyone know of a nice one that is available? Thanks. Ryan

Public mainframe system

by fraveydank＠gmail.com

Not to reignite a somewhat sensitive topic, but if anyone was interested (like I was) in a publicly-accessible modern(ish) IBM mainframe system, the FanDeZhi system at zos.efglobe.com seems to be back up. You can acquire a free account here: http://zos.efglobe.com/cgi-bin/mainframe/mainuser?F=APPLY I logged in today and quickly discovered I have no idea what to do. Time to read up... - Dave

Like I said, I've learned my lesson; since offering something for sale here before it is scrapped is not appreciated and instead earns the censure of folks like you who on principle won't buy it from me anyway, I'll avoid offending you and simply offer it elsewhere and/or scrap it *without* offering it first. > Unless you are also Steven Landon (and maybe even then - see below), or > unless you've pulled such a stunt in the past and I've lost track of it, I > don't see why _you_ are getting bent out of shape over this. I have no love or respect for Landon whatsoever but I can see myself saying exactly the same thing, i.e. "I've got to get rid of some stuff and if I can't sell it by YY/MM/DD then I'm going to give it to Goodwill" (where you could presumably pick it up anyway if you're in a position to pick up in the first place); thus, the critical replies and comments could just as well be directed at me, which is why I stuck my nose in. If I give it to Goodwill or scrap it I never have to think about it again; no waiting for folks to show up who never do, no endless email exchanges, no listening to their complaints, no seeing it on eBay for $100 the next day, etc. etc. and I think I'm entitled to choose whether to put up with those hassles without any compensation. If you think that making my choice clear is emotional blackmail, then so be it. > ...the response from someone who actually cares about the hobby instead of > about yanking others' emotional chains would have been more along the > lines of "oh $#!+, is that what they do? Then...", or perhaps "actually, > I asked them and the real policy here is...". I guess I accepted a long time ago that millions of tons of useful and valuable stuff gets buried, crushed or melted down every day and I don't get as emotional about it as you think I should; if I think it should be saved and am in a position to do so, I will; what other people choose to do is up to them. Sorry if I'm not caring enough about the fate of old computers, or sensitive and considerate enough of your feelings... As I just replied to someone off-list, I find it sad and a little depressing to see the animosity, *judgements* and personal attacks so prevalent on this list, which is after all intended to bring fellow members of a community together to share knowledge, experience etc. and in general help each other...

Mylex MAE486-33 BIOS needed

by teoz＠neo.rr.com

I won an old 486 EISA motherboard on ebay missing a few chips most importantly is the BIOS. Mylex MAE486-33 Rev P2, anyone have the BIOS file for it? Manual says: l Verify that the BIOS chip is a 28-pin, 27512 chip, with a 200 ns access time. W For the MAE486 - verify that the BIOS chip is marked "EISA BIOS 486 MAE rev xx" I found the bios for the MBE486 online but that's a different board. And I did find the EISA config files. I think it is missing the keyboard controller, and 2 Dallas RTC chips as well (have one of them at least). Working EISA 486 are getting hard to find. Thanks TZ

Collection reduction - PDP 11/45

by jim＠g1jbg.co.uk

Hi all, I'm going to get rid of my PDP11/45. The processor is complete, and has solid state memory (non-DEC), and has power supplies. There is also an RK11 backplane in the processor box (may have some spare cards somewhere). The machine has not been powered for 5 years, and will need the power supplies looking at. There is also a unibus expansion box, with power supply (no cards / options fitted), and an untested RK05 drive. This is all in an original DEC cabinet with side panels and rear door. The machine is to be collected from Southampton, UK. I am open to reasonable offers (I know roughly what I want, but I'll see if I have the value about right!). Thanks Jim.

Was someone on here expressing interest in a Mac LC475?

I was emailing with someone recently -- as in the last few weeks -- who was interested in one for the cost of postage from the UK. However, foolishly, I have lost the email thread. (I have 22,512 threads in my inbox.) If you're interested, do please drop me an email. I've dug the machine out to check it boots, and I have found a suitable (well, slightly overlarge) box. -- Liam Proven ? Profile: http://lproven.livejournal.com/profile Email: lproven at cix.co.uk ?

Waste Management (the company) and vintage computers...

by jules.richardson99＠gmail.com

Anyone had any dealings with them in this regard? I expect that they run a lot of local landfill sites (at least here in the US, but I think they're a global company). I've got a contact at my local one who tries to set aside for me anything that they think I might find interesting, but management policy is that nothing can leave the site once dropped off, and it sounds like this rule will be more strictly enforced in a couple of weeks' time following a site audit. I was considering contacting their management to see if there's any way to officially secure vintage items, and was wondering if anyone else has done this successfully? (In particular, it would be nice to know ahead of time what their main concerns are - if it's a liability issue, say, or if they perhaps see monetary value in e-waste) cheers Jules

Available S-100 PCBs

by LYNCHAJ＠YAHOO.COM

Hi If you sent a PayPal for one of the S-100 PCBs and have *NOT* received an email confirming I've shipped your boards or the boards themselves PLEASE CONTACT ME IMMEDIATELY! There has been an instance of a PayPal email either not arriving or getting lost. I don't know if this is a "one time" deal or part of a larger problem. Maybe its related to the general confusion and nuttiness happening in the US over the last few days. Whatever the problem is I need to know right away. If you've paid for a PCB, it will be shipped or you'll get a refund. No exceptions! Thanks and have a nice day!

DEC M7522 card (RUX50: RX50 for Unibus)

by pbirkel＠gmail.com

All; I've made a bit of progress in my quest, having serendipitously acquired a DEC M7522 card (RUX50: RX50 for Unibus) as part of a pile-of-parts. It has two obvious problems. 1. A 0.6"-wide 40-pin socketed DIP that is top-center on the board has been trashed (literally, the top scraped off and the die exposed!). (The socketed 82S105 just below it mid-board is just fine.) The ruined chip appears to be a CPU; what is it really? Maybe a T-11? (The FD1796 is somewhat to its right -- midway to the Berg connector, soldered-down, and looks just fine!) 2. A pair of 0.6"-wide 28-pin socketed (presumed) EPROMs (mid-left on the board, next to a pair of HM6264P-15) are missing. What are/were these (type, speed)? The board otherwise looks absolutely perfect, excepting damage to some of the handles. I'm still having no luck finding any documentation for this board; a printset is especially desired. I throw myself onto the good graces of the community to examine that M7522 card that you have in your system (or on your shelf) in order to verify what the apparent-CPU is/was, the EPROM-type/speed (2764? 150ns?), and to either point me to a copy of the EPROM contents for the chip-pair or graciously offer to extract a copy of yours :->. I'd be happy to send some blanks if you have the means to make copies. A quality scan of an intact board would be a helpful start on the chips. Thank you, very much! paul

I happen to think that I not only have a legal right to choose what to do with what most people would consider worthless junk, but that it's really none of your business. But your censure doesn't bother me one bit, and your turning a *Goodwill donation* of fairly common junk into 'dissecting an ASR33 into party favors' just tells me something about trying to discuss something with you... I used to think that when I get rid of something people would appreciate a heads-up before I scrap it, but knowing that you and perhaps others will on principle "refuse to ...buy from" me (thereby *increasing* the likelihood that it'll end up as scrap) and not wanting to get your (and others') underwear in a knot, I just don't bother any more to offer things that have a poor chance of selling before I scrap them (as I have done with dozens of large/heavy systems including several Cromemcos, VG, etc.). >> If you think that such things are precious and need to be protected, > If you don't, what are you on this list for? Considering the OT and childish/judgemental/argumentative/insulting crap that I have to wade through these days I've been asking myself that very question more and more lately... I dunno, I thought perhaps someone might be able to use a part from those systems I've scrapped, or maybe some of the obscure software filling my shelves, or even some useful knowledge from my 40+ years in the field, but no, I don't think that any of the systems in question are particularly precious or rare nor do they need to be "protected"; there are lots of IBM 5150s out there including three rusting in my basement. Some people just want to own them and get upset because they can't for whatever reason... >> then do something about it. Buy them yourself. [...] Anything. >> Just don't go bitching to the mailing list and then expect someone else >> to do it for you. I agree completely; instead of bitching, appreciate that it's being offered at all instead of going straight to Goodwill/scrap/the dump! If you want it then buy it; if you don't and no one else wants it either then it's obviously not worth very much... m

RX11/12 available in Canberra

by doug＠dougswordclock.com

Hi cctalk list! I was wondering if there is anybody in either Canberra or Sydney Australia who has some old DEC hardware that is in need of a new home. I have a PDP11/34 system that would love a RX11 or RX12, so I was looking for a set of drives and a M7846 board for them to plug into. I have a Dick Smith System 80 that I would happily swap :-) -- Doug Jackson DougsWordClocks 35 Fred Lane Crescent, Gordon, ACT, 2906 Australia http://www.dougswordclock.com/

subject tagging, was Re: Who is the moderator of this list?

by barythrin＠gmail.com

In fairness a lot of times its a nondefault but mailing list per user configurable option. I think it isn't perhaps on this server or software but that would be one method of satisfying most. Its not a problem on a real computer or mail client worth a grain of salt however I'm often mobile and also can't view subfolders easily from this crapberry so having a subject line but keeping it in my main inbox would also benefit my ability to keep track of mailing lists and topics. Its also the reason I can't modify the original mail text I'm replying to half the time.
