I used the AY-3-8910 as the heart of a music board for my 11/10 years ago... I had it connected to a DR11-C (16 bit parallel interface). A friend at the time designed a circuit which allowed me to connect a couple of SGC chips and control them, and another friend had translated the stanford music compiler to pdp-11 code and we got it all working... at one point, I had the keyboard of the console VT52 setup to be like a piano...

Cyber205 was RE: Ebay horror ...

Anything right? Oh nonono. Seymour Cray was one of the founders of CDC in 1957. He was the primary architect of nearly all of their early machines, the first of which I believe was the 1604, introduced in 1958. Seymour Cray left CDC in 1972 to form Cray Research, the first product of which was the Cray 1 which shipped in 1976. About the Cyber 205...CDC started the design of the "Star 100" in the mid 1960s. It wasn't completed until 1973, and being based on 1960s technology, it wasn't competitive. It was redesigned in newer LSI technology and re-released as the "Cyber 203E" in 1979. Shortly thereafter it was renamed to "Cyber 205". But yes, it is rectangular. And big. I would give my right arm to be able to restore/preserve/own a functional Cyber205 (or any Cyber for that matter, anybody have a smaller one available?)...the one at Purdue seems to have been gutted, sigh. -Dave McGuire

Ebay horror ...

by mbbrutman＠bresnanlink.net

I'm so mad. I'm watching on Ebay now as a greedy seller takes apart a PCjr, and parts out the individual pieces for obscene amounts of money compared the the cost of an intact system unit. We're talking almost a complete disassembly - he has even removed the IR receiver for the keyboard from the motherboard, and is selling that bundled with a keyboard. That part has no use without the motherboard. The power card, floppy drive card, parallel printer sidecar, and the "RARE" 64Kb memory card are also being listed separately. I polite email to the seller suggesting that the machine is more valuable as a unit basically came back as "I sold one part, the rest is all gravy, I know what I'm doing so mind your own business." So distasteful .... I wish there was a way to blacklist people like this. Mike

9-Track Magtape data Recovery Technique (Last Ditch!)

by dhquebbeman＠theestopinalgroup.com

Hello all... This message is directed at those you who are actively performing data recovery on old 7-track and 9-track tapes. Last summer, just before I toasted my Prime, I was successful at reading data off tapes that were not previously readable (and by previously I mean MY attempts in the weeks prior to that night had failed). The tapes had been stored in a basement that flooded. Then, they were not recovered from the basement until it was pretty much dry (two years later). Oxide was falling off. There was lots of either mineral precipitate or some kinda lichens or fungus growing on the tape. I couldn't even read the label on one of them. I thought judicious cleaning of the tape head might help. I kept trying, no luck. Then I started to drink. As the alcohol took affect, I got a wild idea. My drive is a Cipher F880 streamer. You can slide it out of the rack tray, and if you enter the right sequence of button presses, you can unlock the front door, and even better, the top lid, which provides access to the tape path during operation. So, I took a cleaning swab, soaked it in cleaner (not Freon TF, and likely a poor substitute) and applied it against the tape, directly before the tape read head. It immediately stopped re-trying, and started streaming! When the swab would get dry, I'd pull it away, and almost immediately, the drive would start retrying until once again, I brought the wet swab against the tape. Doubtless, this is going to leave all kinds of crud on the tape path, and might even shorten the drive's life. But Cipher F880's are a dime a dozen; data on tapes a bit more rare. Has anyone else ever tried this? I know what you're thinking, flaky jerk, getting drunk and burning up vintage hardware. But it worked! I spent a few hours looking at the files to make sure they were intact; they were. I transferred some of them, but not all, as I don't have a transfer program to get stuff off the Prime right now (other than to simply list it and capture the listing). I have other tapes right now that I'd like read; I sent them to someone who tried, and they said they could not even read the first block, indicating that they might be 7-track instead of 9-track (possible). Anyway, there it is, bread cast upon the waters. With any luck at all, I'll get a sandwich out of it. Regards, -doug q

VAXstation 3100

by dittman＠dittman.net

Is there anyone in the Dallas area that would be interested in a couple of VAXstation 3100 boxes? They both have color video boards (not sure of the model, though), but one of the boards has a problem. One unit has no memory other than the 4MB on-board. The other unit has two optional memory boards for a total of 32MB. One of the units has a dual SCSI board and the other has a SCSI/MFM board (and a defective floppy drive). One of the systems was also modified with the faster clock, but a socket was installed so it can be restored to the usual speed. Neither of the units have any internal hard drives. I can't remember if they have the internal cables, but I think they do. I haven't used these in about three years, having upgraded to a VAXstation 4000/60. I don't want to ship them, so if you are in the area you can have them both for $50, or if you think that's too much, make an offer. If I don't have any local takers I'll be open to shipping them. -- Eric Dittman dittman(a)dittman.net

I am not sure this was always true of uucpd; I have a vague recollection of some system on which uucpd was intended to run as an independent daemon that opened port 540 directly, and can't remember whether that was the behavior of earlier BSD Unix or was just a brain-damaged implementation from a Unix vendor that didn't get it. Taylor UUCP supports running uucico directly from inetd. If you give uucico a -l argument it will issue "login:" and "Password:" prompts and do login authentication using its own list of users and passwords (not /etc/passwd).

Interest in UUCP?

If we are talking unique networks, how about: 1. I think what we need is a series of iridium phones and modems, we can be "outside" of the regular networks. 2. Maybe a series of store and forward cell phone sites. You call and download an analog data file and each node forwards the call to the next nearest site until you reach the destination. 3.

Cool find...Quest Super Elf

by jhellige＠earthlink.net

Didn't someone on the list ask about the schematics and such to the Quest Super Elf a little while back? As of today, I am the proud owner of one of these machines. It was shipped from Quest on January 27, 1981 as a kit and assembled by the original owner. The total cost of the kit as shipped was $112.85. He added the full hex display, including low and high address displays and he also gave me it's PSU, Quest catalog dated Jan 81, and the original reference manual. It's also still in it's original box. If anyone still needs info, let me know. Jeff

Book Search

by dhquebbeman＠theestopinalgroup.com

There's a great book by Gordon Bell and others entitled "Computer Structures: Principles & Examples" which is online at www.ulib.org... However, there are a few pages in it they didn't OCR, but instead just scanned and put up on the web. Unfortunately, they weren't scanned in sufficient resolution to be readable. Does anyone out there have a copy of this book? What I need are the instruction-set processor listings for the CDC 6600 Peripheral & Control Processor on pages 737-738, and the isp for the CPU of the same machine, pages 739-742. The scans need be only hi-res enough for me to OCR; as an alternative, I'll take photocopies, but I'd rather not leave this to someone else to OCR for me (actually, I don't mind someone else OCR'ing it for me as long as I can get printed or scanned copies to use as a sanity check). This book should not be confused with Bell, et. al., "Computer Structures: Readings and Examples". Also a great book, but lacking the info I need. Thanks, -doug quebbeman

old external Apple drive

by PeksaDO＠Cardiff.ac.uk

My Western Digital 20AP opens as follows: 1) Grow extra hand 2) Back of case, about 1.5" to right of AC socket, at the bottom of the upper half of the ventilation grill is a small plastic lug. Depress it with a flat blade screwdriver of similar. 3) Simultaenously use two PC (spit !) card blanking plates on each side of the case (There is a small 0.5" slot in the bottom of the three styling ribs on the side of the case) and press to bend the two side plastic lugs 4) You should now be able to lift the top of the case from the back while the front edge rotates about the join between the upper and lower halves. After lifting a little way there will be sufficient play to slide the top of the case forward in order to overcome the bits of plastic in the top of the case which interlock with the bottom of the case.

IBM 5110 available (two)

by sieler＠allegro.com

Hi, Passing this on for a friend...email him, not me! There are two IBM 5110 computers (BASIC only) available from bfrogel1(a)san.rr.com They're in Chatanooga, TN, and are in running condition. They include the large 8" floppy disk drives ... and, no "large" isn't a reference to 8" vs. modern floppies (check the picture and see!) Pictures at: http://www.sieler.com/ibm5110/ I'm not associated with Bernard, or the sale of the two computers... I was thinking about buying them, and put the pictures on my web site so a friend could look at them. (The cabinet below each computer is *just* a dual 8" floppy drive... a year later, IBM had shrunk the drive electronics to the point where they could integrate the drives into the computer, and still have a desktop computer!) I think he's looking for $1500 for the pair, not including shipping. He's the original purchaser, and used them in his business. -- Stan Sieler sieler(a)allegro.com www.allegro.com/sieler/wanted/index.html www.sieler.com

Manuals to PDF advice sought

by Marion.Bates＠dartmouth.edu

Hi, I've run into the same difficulties trying to do the same thing before, using Acrobat 3. I found that if I used the actual Acrobat programs (duh can't remember the names of the individual "pieces") then I always wound up with huge files. BUT if I used the silly little AcrobatPDFWriter printer driver to "print" PDFs from Photoshop, they are always much smaller...undoubtedly this is due to my not understanding what the heck I'm doing with Acrobat Exchange (ah that's the name) but maybe give that a try if you haven't already. Also, and this is something you probably already know, but unless the stuff you're scanning contains images with gradients (i.e. photographic) you can drop the bitlevel to 2 (true black-and-white) and up the scanning DPI to 300 or 600 and get very sharp results with that. They will print like new. If you then print _that_ from Photoshop to the PDFWriter you'll probably get some good results. I think Acrobat has some compression options as well. Can't really remember the details. Re: OCR -- Trouble I've had is (and this is just pickiness, if the actual info's all you care about then it's no prob) you invariably lose the font and other aspects of the original appearance of the document, which is a bummer. I converted a PDF of Sun Remarketing's Lisa DIY guide into HTML with images because I wanted search engines to be able to index the content. I used Omnipage Pro 8 which has a very convenient save-to-HTML feature and it even knows to pull out the images and save those as high-res JPEGs. So if you do end up going the OCR route, Omnipage is great. Textbridge Pro is "smart" about reading text accurately, but I think it lacks the features of Omnipage. You could also send me a sample scanned image (try a few different resolution combinations) off-list and I'll see what kind of results I can get, and send 'em back... HTH. Good luck! -- MB --- classiccmp(a)classiccmp.org wrote: I've decided that I would like to start converting various documentation I have to PDF, mainly newsletters and such for the Model 2000 that seem to be otherwise nearly impossible to find. In fact, I'd like to eventually cut a CD that pretty much covered the machine and it's docs. My question is, how do I best go about doing this? I've tried a couple of newsletters already and scanning them using Photoshop as a grayscale TIFF's at 100dpi, so as to preserve botht the layout and any diagrams and such, and then importing the images into Acrobat ended up with a 6.3meg PDF for a 20page 8.5x11 newsletter. If I scan the newsletters as a bi-tone image the text comes out all blotchy. I also scanned a 4 page 8.5x11 glossy color flyer, using truecolor settings at 200dpi, and it ended up as a 32meg file. I don't have any OCR software but I do have Acrobat 4.0 and Photoshop 2.5.1. Yes, I know it's an extremely old version of Photoshop but it does the job and Acrobat doesn't like my scanner plugin while Photoshop works with it fine. Acrobat PDF Writer works from other programs fine as well, having easily converted my FAQ to a 32k PDF by 'printing' to it from within Netscape. The scanner is a Piotech Splendeur 3024, a rebadged Relisys Infinity Scorpio, capapble of 30bit color at a maximum optical resolution of 300 x 1200. It's capable of 2400 x 2400 with software interpolation. Any suggestions would be greatly appreciated. Thanks Jeff --- end of quote ---

The contacts in the connector only use the lowest 0.475" of the card edge, although the contact area extends to 0.56" from the edge of the board. The housing part of course is shaped to ensure you don't plug a dual- or quad-height card in backwards. Anyway, I just checked on an S100 edge connector (same 0.125" pitch), and its contacts are the same depth as the DEC ones. S100 connectors are getting expensive thses days, so cutting them up probably isn't a good option, but I'm sure any standard 1/8" pitch edge connector will do if you're not worried about the keyways. -- Pete Peter Turnbull Network Manager University of York

Devoted site to the Otrona Attache?

by Robert_Feldman＠jdedwards.com

I don't know of any Otrona specific sites, but do you still provide (http://www.gaby.de/sysdisk.htm) the system disks Don? I have a working 8:16 (upgraded to 640K by Brown Enterprises) with both User Guides and a small Service Guide. I have been corresponding with someone in Australia who has the technical manuals and an Otrona that will not keep time or boot. I've been thinking of scanning my Service Guide for this chap. If I do, I will make it available. I will see if we can get his technical manuals scanned, too. I have the CP/M and MS-DOS 2.11e disks. The latter was in development when Otrona went bankrupt, but was distributed by the Attache User's Group out of S.F. I also have some of the sales literature and the last User's Group newsletters and disks (one of which contains a buggy source of the BIOS). BTW, Don, I have a 5027 I will part with (contact me offlist). I got it as a spare (I had heard they often went out) when I took my Otrona to Peru to use with an archaeological project. A fellow archaeologist here in Chicago at the Oriental Institute used his in the Middle East. He got Autodesk to customize AutoCAD (version 1.4) for the Otrona, although apparently, in the end, John Walker felt it was a waste of time. I still have a copy of the Otrona AutoCAD, but don't have the proper mouse or digitizer to use it effectively.

PC Adapter Tech Ref

I have it, but it's not going to be available for loan. I use it too much. At one point the option cards were covered in the TechRefs for the machines themselves. Then, when it was realised that several manuals contained the same information (after all, many of the options went on serveral machines), the machine TechRefs covered the keyboard, motherboard and PSU only, and the options were covered by the O&A techrefs. Originally it was 2 volums, always sold together by IBM. These cover all the options and adapters that go in the PC and XT machines. Volume 1 covers the expansion cablinet, monitors and printers, volume 2 covers the expansion cards, cables, etc. I think that's right anyway. You get schematics, programming info and often the BIOS source code if applicable (there's the source code for the XT hard disk bios, for example). There are then a lot of suplements. There is one for AT option cards (hard/floppy disk controller, serial/parallel adapter, etc). There's one for the EGA card (this does contain schematics and BIOS sources). There's another complete volume for the 'scientific' options (Data aquisition/control adapter, GPIB card, Professional Graphics Controller (no ROM listings for that :-(). There are also individual suplements for later options, like the 3.5" drives, later hard disks, etc. MAny of the later suplements don't contain schematics or ROM source, though. The older ones do. I have the 2 volume set, the AT supplement, the Scientific O&A volume, the EGA suplement and probably other odd bits. It may still be available from IBM. Last I heard (this was a few years ago), it was out of print but they still had some in stock. It's not cheap, though. -tony

Heh heh. Don't we all collect classic programmers as well? I do. I have three or four including a Data I/O that we used to program 6309 and similar fusible link PROMs for the original model COMBOARD (8Mhz 68000, 32Kb of 2114 SRAM, .5Kb PROM). The one that I use most often is a universal programmer attached to a Commodore Colt. I've asked before about software (I don't have the last rev for it). It's a UP600a. I also have a programmer for the C-64 - "Promenade", I think it's called. While I may be able to program a 2708, I don't think I can do 1702As. -ethan ===== Visit "The Seventh Continent" http://penguincentral.com/penguincentral.html __________________________________________________ Do You Yahoo!?

SBUS graphics cards for Suns to get rid of

by kfergaso＠swbell.net

I have some Vitec Rasterflex cards I'm looking to get rid of. double wide SBUS, 3 of them. Also, a single wide that says Bit 3 Computer Corporation, with a connector that has about 62 pins. That card might be the interface to the graphics controller box, but I don't have that. These are for Sun Sparc, and they work in Sparc 2 and 10 systems, (and possibly others). They are untested, though they did work many years ago. Has software on QIC, and manual. <ebay hypermarketing> Rare!! Upgrade your Sparc 2 to 24bit graphics!!!! </ebay hypermarketing> Best offer by Thursday afternoon, or I toss them, (or worse, try Ebay...:-)) Please reply off-list to kfergaso(a)swbell.net for if anyone wants more info.

Questions regarding a PDP11/34a

by ndiablo＠diablonet.net

Hi everyone! Recently I've been taking a closer look at a system that I rescued last summer from the property disposition department of one of the local higher education concerns - a relatively well-equipped PDP11/34a along with a rather broken RX02 disk drive. As far as I can tell, the PDP11 system is in fine working condition. I had to put a new power cord on it (the old one was chopped off when the system was decommisioned for some reason), but barring that, it powers up and the front panel seems alive. The machine has the following configuration: M8256 PDP11/34a data paths module (KD11-EA) M8266 PDP11/34a control module (KD11-EA) M8204 Microprocessor, DMC-11 code, 1kb memory (KMC11-A) M7867 SDLC or DDCMP sync interface (DUP11-DA) M7867 SDLC or DDCMP sync interface (DUP11-DA) M7856 RS-232 SLU with RTC (DL11-W) BM873-YJ ?? M7859 Front panel console interface (KY11-YB) M9202 Unibus connector M7850 Parity for G651, MS-11 (MM11-BP/CP) G652+H222A 16 kword 16 to 18 bit motherboard with 16 kword 18 bit core stack (MM11-DP) G652+H222A 16 kword 16 to 18 bit motherboard with 16 kword 18 bit core stack (MM11-DP) M9202 Unibus connector M7258 Dataproducts interface printer controller (LP11) I guess I've got a few questions about this machine. They go something like this: 1. Does anyone have the pinouts for the serial line connector on the DL11 board? I've got the board, but the cable had been disconnected from it. 2. Does anyone know what that BM873-YJ board is? I'm just curious. 3. What would be the best way to get this old system running again? I've got no interface to that RX02 drive, and even if I did, I think half of it is pretty well broken - the plastic frame of the disk drive is cracked. I tried to glue it, but even if that worked, I imagine it must be terribly out of alignment now. I thought I remember someone asking about loading software over a serial line? I've got my guesses as to what this system did in a past life. Perhaps it ran as a front-end for the IBM mainframe that the university ran, or perhaps it served as a router-type device on the MichNet network years back.. Maybe it didn't do either of these things. I'm not sure! Thanks for any help! --Sean Caron (root(a)diablonet.net) | http://www.diablonet.net

IMSAI EPROMS

by jweder＠telusplanet.com

Hi all... I've been trying to get some action from this IMSAI for awhile now. Main problem is I don't know what is on the EPROMs on the EconoROM board. It looks like banks A & B, OR banks C & D, can be enabled together starting at address 0000h. There are 6 2708's in A0 through B1, and 8 2708's in C0 through C3. I've been looking for an EPROM burner that can read/write 2708's with no luck so far. We have TWO machines at work, and neither will do it. Anyone know of a burner that WILL? I manually read the first 256 bytes of the first chip, and disassembled it, also manually - I'm looking for a good disassembler program too! I've got one called DASM V1.2 by John Wilson, but have been having some trouble with it. If you've got a few minutes, have a look at what I've included below - the first 128 bytes of code. Let me know if any of it looks familiar. (Or if I messed up the job!) The comments are for my own benefit - I'm pretty rusty with assembler. Addr.
