>What am I supposed to do if it becomes obvious I am not going to be able to >track the guy down? (which it has, except for the new idea of trying name >lookup directories, I do know his name and his former city and state.) You could pass them on to the next person that needs a copy. Or even start a "library" of sorts with it. You send it to someone, they use it and send it back, and you hold it until the next person needs it. Of course, that gets into copyright issues, but I'd assume either you aren't worried, or it doesn't apply, if you already "borrowed" a copy to begin with. >and hope everyone doesn't think I am some kind of miserable >lying bastard. This was an honest mistake. Like someone else pointed out, don't be TOO hard on yourself... had the guy REALLY wanted it back, he would have hounded you for it (unless he did, and you just didn't share that fact). I don't know about others, but I NEVER loan my only copy of something to anyone that I can't drive to their house and beat them until they give it back (and even then, they have to be someone I know well and trust). But I will happily loan extra copies of something, or duplicates of it. In those cases, I except the fact that I may never see it again, and I don't care... if a basic attempt doesn't get it returned, then I just write it off. Good chance this guy was the same way. -chris <http://www.mythtech.net>

Slightly OT: Ethics

by torquil＠chemist.com

So about 2.5 years ago, I bought an SGI machine off ebay and the guy let me borrow the IRIX 6.5 media. I never sent them back and contacted him like 4 months later and said "Whoa I forgot to send them back, can I have your address?" I meant to send them, but forgot *again*. I have tried to email him every 5-6 months for the past two years, but his e-mail is dead (domain name is gone) and his ebay account hasn't been used since 2002. What do I do? I am thinking it'd be okay to sell the CDs and if I ever do by some chance find him again, then I can give him the money. I feel really bad about this. Any advice? --- Thanks, Torquil MacCorkle, III Lexington, Virginia

No, because I am officially at war with USA, which is an illegitimate colonial occupant of the land I reside on. This land belongs to the Native American people, who rightfully hate "the white man" (their term for the bourgeois USA nation-state) and fully support me and my work, of which they are quite aware (here I mean not my VAX work, but my work on history of civilisation, ET connections and exopolitics).

MicroVAX 3100 M10

by mpokorni2000＠yahoo.com

In general, MicroVAX III could handle 64 Meg, though some CPU boards did not have all address lines brought out of Memory Controll Unit pins. Here my memory gets fuzzy, I am not sure whether that was the case only with those 'workstation' types or that was also a case with backplane based machines. There was an outfit that was retrofitting such CPU boards for full range of addresses and I do rememmer whether they were Stateside or in Holland. The largest Digital memory for backplane based MicroVAX III was a 32 MB board, but that came quite late in the life of MicroVAX III. The initial 'Minimum Configuration' shipments of those systems were with 8 Meg, then that was upped to 16 Meg. The 4 Meg board that is mentioned, is probably partially populated 8 Meg layout. However, there were third party boards up to 48 MB. Rational for that corkey size was that customer does not have to trow away original 16 Meg that came with machine and still fit full 64 Meg complement into two slots.

Once I removed the cover, I could clearly tell that the "chirp" is coming from the switching power supply. There appears to be no activity from the rest of the monitor, including the fact that even with the lights off, I could not observe filaments lighting. The power LED does light, however it's fairly dim - I don't know how brightly it would normally light. The final filter capacitor in the supply is rated at 180v DC. I powered the supply briefly under no-load and the output rose to 140v. With all the connections in place, it is producing about 55v - I have no idea what the normal requirements of the monitor are. This is where a set of schematics would really help (anyone ???)

(Want a few Iisi's, perhaps? A few 20MB Rodime hard drives with external actuators?) What happened with your Iifx? If you're really going to scrap the II I could perhaps be persuaded to give it a home; haven't had my hands on one since I ran one as a file server in 1991-2; somewhere I still have AppleShare and the AppleTalk Internet Router software I used back then. That was a really hot network (not) - 6 SE's, an SE30, an original LC, a Iisi, a II as a server, another II as a workstation, a Shiva Telebridge and an Avatar MacMainFrame SDLC gateway to a remote CICS host and a LaserWriter IINT. All on PhoneNet, too. Another SE was used to dial into the Telebridge at 2400BPS thru a Practical Peripherals modem. 90MB SCSI Bernoulli on the SE30 for backup. We even had a PC in on this party using a PC AppleTalk card. Ran FileMaker II for a workgroup plus Word 5, Excel, PageMaker 3, Canvas 2.1 and the Avatar software for mainframe session access. The Avatar printer emulator ran on a dedicated SE driving an OKI dot-matrix printer through a serial-to-parallel adapter as I recall. Worked fine, too. The leased-line modem for the remote mainframe access was easily as big as a Mac II; as I recall the II sat on top of it. Quite the setup. Drove our MIS guy nuts that this arrangement of odds and ends set up by an amateur - all units were out of production by then except maybe the Iisi - was stable but his Novell setup crashed every few days. I figure your Mac II and my ImageWriter LQ would make a handsome 'couple' while completely covering a good sized desk's top. Nothing like old Apple hardware - I'm still printing on the LaserWriter II I bought new in 1989. Works fine. Slowly, but fine. Seth Lewin

Couple DEC items seen on eBay

by classiccmp＠crash.com

Lost control and wandered through ePay for a bit today. A few things someone might be interested in, all DEC, all the same seller as he caught my eye with a laptop and had all these goodies listed. No affiliation. I know I've had some email conversations, not sure if I bought anything, but he seemed reasonable. YMMV. VAX 8530, single cabinet with Console 380 sitting on top, appears cabling is intact. CI interface. Guy wants $250, wonder if he won't make a deal after nobody bids... http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=1486&item=3091806283 "DEC Memory Array Tester". It's late enough that it's got what look like Euro connectors, but I can't guess what flavor of DEC memory interconnect it's for. Certainly post-Unibus. Has a sheaf of papers in the lid, unclear if they're docs. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=25423&item=3810462266 RK07-EF disk pack, allegedly new in box. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=3756&item=4125693956 Share and enjoy, --Steve.

Help with Atari 1050 disk system - success!

A standard PC drive runs at rotational spindle speed of 300 RPM. According to the FAQ's and some of the documents included with the various Atari<>PC disk transfer packages that I have looked at in the past couple of days, the Atari 1050 drive runs at a nominal speed of 288 RPM. The disk copying package that I managed to download and boot included a drive speed test - my drive weighed in at 287 RPM, so it would appear that this information is correct.

Looking for Atari SC1224 monitor schematic

by dave04a＠dunfield.com

Hi Everybody, Picked up another 520ST (same flea market as 1050 drive) - it's a later edition as it has the power supply and floppy drive built in like my 1040ST. My other 520ST requires an external floppy and drive. Anyway, the machine itself works fine, however the Atari SC1224 monitor that came with it does not. I can hear it "chirp" when I throw the switch, suggesting that the horizontal oscilator is running, however I never get any light on the screen - no apparent "static bristle", so there may be no HV, but I can't tell for sure haven't opened it yet. Anyone got a set of schematics for the SC1224? Btw, does anyone know if the internal floppy drive of a 520ST is a single-sided drive like the external SF354 drive? Or a double sided drive like is in the 1040ST?

Help with Atari 1050 disk system - success!

by dave04a＠dunfield.com

Hi Everybody, (Hi doctor Nick) I discovered that I had a couple of power supplies all along. I remembered this afternoon that I have a couple of Atari 1010 Cassette drives tucked away, so I dug em out and sure enough: Atari 9v 31va supply - just what the doctor ordered. I also found a program called WRITEATA which tries to write Atari format disks on a standard PC drive. It has trouble due to differences in drive speed and the fact that it can't do 128 byte sectors, however I was able to get it to write 130k "enhanced format" 1050 disks. Most Atari DOS images I've found are 90k which it can't do, however I found one called "TurboDos" in a 130k image, and was able to write it and it booted! It booted and then crashed on the 600XL I was originally testing with, however I noticed a message indicating "XE RAMDISK LOADED" ... so I tried a 130XE and everything worked - it comes up in some sort of menu program written in basic, which I could exit (to BASIC), then use "DOS" to get to DOS - so my drive does work! I also found a 130k disk copying disk that works, it appears to have a German version of Atari DOS 2.5 underneath it. Thanks to everyone who helped me figure this out.

MORE 1802s!!!

by rigdonj＠cfl.rr.com

I made a major score of 1802s recently. A couple of weeks ago I went a scrap place and found some old traffic controllers. I opened one and found that they all used socketed 1802 CPUs. I pulled over 50 of them :-) The controllers were Transyt moddel 1800s and they're made in Tallahassee Florida. Here is a not so good picture of what they look like <http://www.signalfan.freeservers.com/controllers/transyt1.htm>. FWIW I also found a couple of Eagle controllers and I checked them, they used 68008 CPUs. OK, Now go find those controllers! Joe

Need help with Atari 1050 disk system

Last night, I took the drive apart and checked it out (all looks good), I could see a rectifier on the input, so I concur that it is AC. I cobbled together a 9V ac supply and powered it up - I did observe exactly what you indicate, the drive comes on, spins, and the head steps out and back >from and to track zero. >The software that came with the 1050 only made it a "dual density" as they >called it drive.

You can send commands directly to the >drives (without DOS) to do "primates" like Format a disk, and data sector >puts / gets. I hope this helps. If I connect the drive to a computer, I observed the following: With not disk in the drive, the computer rapidly issues "Boot error" messages continuously, and the drive remains stopped. With a disk in the drive (not an Aari disk), the drive activates, and the computer issues "Boot error" much more slowly - clearly it is trying to read the unformatted disk. So - I think the drive is working. I was unable to find any way to get the system up with the drive connected, so I don't see how there could be DOS in ROM as some people have suggested. Any ideas? Is it possible to do anything with the disk without a DOS boot disk. This sounds like a very simiar arrangement to the C64 1541 drive, except that the commodore boots "normally" in BASIC and you can send commands to the drive via BASIC file operations - the Atari appears to want to boot from the drive before you can do anything. I'm planning to build a SIO2PC cable as soon as I can dig up an extra Atari peripheral cable.

Need help with Atari 1050 disk system

by dave04a＠dunfield.com

Hi Everybody, (Hi doctor Nick) Picked up some more old Atari equipment at a flea market this weekend, among other things, I got a 1050 disk drive. I have not had one of these before. #1) Can anyone tell me the power requirements of this drive? (voltage, polarity, current) - this information should be on the label of the power supply - as you probably guessed, I did not get the supply with the drive (had an Atari computer supply in the box). #2) The box says "Includes DOS 3 Double Density Disk Operating System", but there were no diskettes in the box at all - presumably I need some sort of boot disk... Anyone out there with one that can make a copy or send an image (Can Atari images be read/written on a PC's drive?) Any help would be greatly appreciated. Regards, Dave -- dave04a (at) Dave Dunfield dunfield (dot) Firmware development services & tools: www.dunfield.com com Vintage computing equipment collector.

save the Mac II (original)

by I.Savvidis＠cmc.ase.gr

Dear Mr. Allain hello. If nobody else is interested I would like to have it, if you don't mind sending it to Fairfax, Virginia. I'll pay of course for packing and postage. Thank you in advance, John Savvidis -----Original Message----- From: John Allain [mailto:allain@panix.com] Sent: Monday, April 19, 2004 6:58 PM To: General Discussion: On-Topic and Off-Topic Posts Subject: save the Mac II (original) Would somebody please take my Mac II? I saved it from being scrapped at the office because of it's history, in that it was Apple's big redesign, the first machine of the new line -- one that completed with IBM's PS/2 line and argubly was a greater success. I'm not a big Apple expert but it just seemed if you were going to have a few Macs that this model would be in the top 5. This one comes with a HiRes graphics card, matching Ikegami monitor (17" but compact) cables, software, etc. They don't seem to be that common, when you strip away all the variants, I haven't really found a place to get this original model. Help save the classiccmp. John A.

by vax3900＠yahoo.com

My friend told me that they are going to get rid off a HP E-series computer from their storage. It is a big box with two rows of switches on the bottom half of front panel. I am a vax guy and need some $$$ to invest into my 3900. Do you guys think it worths to epaying it? Thank you. __________________________________ Do you Yahoo!? Yahoo!

Does anyone have National Semiconductor's Appnote AN-359?

by dickset＠amanda.spole.gov

I have this INS8073-based board with four TIL-311s, an 8255, a 6116 and a socket for another, an 82S23 PROM, and an MM58174A. The MM58174A is a clock/calendar chip for which I can't seem to get the appnote for. Google reveals an old location at the Nat'l Semi webpage (it has been removed from their appnote dir), and a single reference at http://www.nalanda.nitc.ac.in/industry/appnotes/Natsemi/AN-359.pdf which refuses my connections (could be down, could be blocking U.S. access; not sure which). I don't care if the Digital Library of the Calcutta Technical Institute is up or not; all I'm after is the app note for the MM58174A. Does anyone on the list have the file 'AN-359.pdf'? Thanks, -ethan P.S. - I realize a picture speaks a thousand words, but does anyone recognize the device I've described? It was a gift from someone, years ago. I brought it with me both as a source of TIL-311s and because it's a complete INS8073 SBC. From what I can gather so far, it's pretty close to the Nat'l Semi reference design, down to using a 741-style RS-232 converter for the console interface. The only useful markings on the PCB are "MC-1N REV-A". The layout of the TIL-311s and the four pushbuttons on the corners of the front panel suggest to me some sort of digital timer. There's a 2x5 jumper block on the front that appears to be input power, serial in/out and a few of the CPU flag pins (F2, F3). There's a 1x9 jumper block on the back that seems to be just options, not I/O, but I haven't traced the whole board out yet. P.P.S. - in case you don't recognize the CPU part number, INS8073, it's a microcontroller with Tiny Basic onboard - you wire on a level shifter, an SRAM and an optional ROM, and _bang_, a microcontroller with a built- in development system. It's the same processor used in the RB5X robot. I have had this board for years, and last year, I picked up a few CPU chips on ePay for a few bucks each. They are one of the many classic toys I brought with me to play with through the long, winter night. -- Ethan Dicks, A-130-S Current South Pole Weather at 18-Apr-2004 13:50 Z South Pole Station PSC 468 Box 400 Temp -70.8 F (-57.1 C) Windchill -94.5 F (-70.3 C) APO AP 96598 Wind 6.2 kts Grid 074 Barometer 689 mb (10289. ft) Ethan.Dicks(a)amanda.spole.gov http://penguincentral.com/penguincentral.html

TDC1007 / 1007 / TRW / Rare TRW Processor ?

by Innfogra＠aol.com

I have seen some of these before. I had some like this from TRW. Not sure of the numbers though. I remember the TRW was printed on a piece of aluminum which was glued on top of a plastic chip. IIRC one I peeled apart had an AMD 2901 underneath. Most did not have anything printed on the plastic underneath. Seems TRW was quite propriatary. I also had some that I thought were 68000s underneath but with absolutely no markings. We had to take the aluminum cap off before they could go into scrap. Never saw one glued to silicon or ceramic. 2901s were at the heart of some early computers but is not worth the $175.00 that the seller is asking. Paxton Astoria

simple apple questions

I have the Apple][ reference manual and a whole pile of other Apple reference books and material scanned ... I'd like to make this available, but I have not done so due to the copyright question - posting a published book which was sold on it's own merit seems less legit than manuals which came with hardware.

I'd like to make this available, but I have not >done so due to the copyright question - posting a published book which was sold >on it's own merit seems less legit than manuals which came with hardware. >Anyone have any thoughts/experiences on this? A quick follow-up to this before anyone "jumps" on me - I would not even think about posting something which is still available from standard sources - I have not checked to see if you can actually still buy an A2 reference manual from anyone - perhaps there's someone with a warehouse full of them? As noted above, this is not something that I am currently considering. This is more of a "distant future" question - at some point the original material will not be generally available (this may already be the case for some of it), and people wishing to learn about these historic machines will have to either borrow it or steal it (photocopy/scan etc.) - as books get older, rarer and more fragile, borrowing will become harder and harder, as will physical replication. Are there any procedures in place to allow this material to be preserved, or does it just "die off"? Many of the manufactures of obsolete computer hardware/software that I have been able to contact have been very helpful. For example, when I asked Dr. Grant, co-founder of NorthStar computers if I could post the NorthStar OS & software (under my simulator) and scans of NS documentation, he responded "North Star is defunct so there is no problem whatsoever. Have fun.". I've had similar responses from a number of other people who "own" dead computer companies. Books however are a different matter, with published books, you have both the Author and the Publisher with interests in the book. I think it would be a lot more complex to obtain similar permissions, but to be honest, I have not tried - anyone here ever gotten permission to distribute the content of a published book?

Hey all you AppleII gurus... I am starting into assembly/machine code on my apple IIc+ If I am in the monitor - how do I get back to basic? If I am in basic Call -151 takes me to the monitor right? If I am in the monitor A ! takes me to the mini-asembler URL for reference for the monitor? for the mini-asembler? What do I call to get a character? to print a character? Where is the best place to put my Assembly/Machine code program? Other pointers, tips, opinions, suggestions? Thanks!

DEC VAX 785 and PDP11/70's in Kansas City

The proper way to make a real PDP-11 (or VAX or any other Classic computer) available to everyone who wants one is put them back in FULL PRODUCTION. Not just hobby, but real full production and commercial sales (for a reasonable commercial price). I'm working on a new VAX chip and will soon be putting VAXen in full production. I can't do the same for PDP-11 because it just isn't my area of expertise, but my close fried, comrade and associate Stacy Minkin is more on the PDP-11 side and wants to build a new PDP-11 using FPGA technology just as much as I want to do it for the VAX. If you want new PDP-11s, E-mail him at stacy(a)ivan.Harhan.ORG and tell him that you want to buy a PDP-11 and would be willing to pay a fair commercial price and possibly finance the NRE cost. Stacy is a real engineer with a vision just as grand as mine, so given enough people willing to buy this stuff (for real, commercially, just like in The Days when it was new), he and I can build The Real Thing: real microcoded CPU, honest-to-Daemon UNIBUS, etc., not a poor man's emulator.

Since my previous posting, I've been convinced to drive to Detroit and back instead of flying, so we'll be passing through the above cities and probably spending a day and night in each one. Any pointers to good stuff to do/see in or around any of them or the surrounding areas in terms of techie stuff, old computer stuff, technology surplus stores, museums, robotics, shows, vegetarian restaurants, etc. would be very much appreciated.

Digital RL02 available in Gouverneur, NY

Very interesting stuff. We have a Digital RL02 system w/ dual 14" removable disk packs. We also have more than a few spare 14" 10MB disk packs kicking around. We actually used it until Sept. 1999. It ran a LoadSTAR auto parts POS system in Northern New York State, and was purchased by us in 1981. LoadSTAR, a New Jersey company, was recently acquired by CCI/Triad, now Activant. Is this anything that you might be interested in? Or do you know of anyone?

The 4040 is almost the same as the 4004 except a couple added instructions and twice the memory banks. If someone wants to scan them, I have a set of copies I made from my manual. Becides the general information, it includes schematics for the sim-4 and the 1702A programmer card. I also have the code that goes on the sim-4. I've disassembled this as well for anyone that is interested. Dwight
