Offer: Cache RAM chips from old 486 boards

by woyciesjes＠sbcglobal.net

I've got a couple small boxes for cache RAM chips that have been pulled >from old 486 motherboards. If you want them, it'll cost you a measly sum of $15.00 (US), to cover time, materials & shipping costs. Here's the list of what I've got: Qty: Mfg. part number (first line on chip only) 3 Winbond? W2465AK-15 1 GL? GLT725608-15T 11 ISSI IS61C512-15N 8 UMC UM61512AK-15 8 UMC UM61M256K-15 8 UMC UM61256CK-20 26 UMC UM61256CK-15 65 total chips. I can give you more info off of the chips if you like. I also have 2 Dallas DS1642-070 Timekeeping RAM chips. I got them as samples, intending on sticking them in a SparcStation 1+ I had. I've since given up on that box. These 2 were never stuck in any computer. -- --- Dave Woyciesjes --- ICQ# 905818

WTB: Sun3 SCSI card

by rigdonj＠cfl.rr.com

Pat, Pulled the card and got the number. It's a Sun 501-2015-032 (Fast SCSI-2 and Ethernet SBus Card). It also had a 501-2708 CPU module in it (SM50 SUPERSPARC MODULE?) and a National Instruments SBUS-GPIB card and a bunch of Kingston KTS 32000/S20 128MB (2x 64MB) KTS 32000/S20 memory sticks in it. Joe Do you have a PN for the card? I have a SUN sitting behind me with what looks like a SCSI/Ethernet card in it. The cover is missing so I don't know what model the puter is but it's one of the pizza boxs. I'll pull the card and get it's PN.

Help setting up a SBS/Bit3 PCI-to-VMEBus cards

by RMeenaks＠OLF.COM

Hi Chris, Drivers for the SBS 616 are available for Windows XP/Linux/Solaris here: http://www.sbs.com/products/software/280 I picked mine up on ebay. I also picked up a SBUS-to-VME one as well, but its from Performance Tech SBS915 as well. There is currently one on ebay for a relatively cheap price (picked mine >from the same guy): http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=51239&item=3983996787 &rd=1&ssPageName=WDVW And its New in Box condition like mines. Now, if my board needs to use J2 connectors, do I need to install that on top of the terminators as well? The transputer boards has its own J2 plug which I installed on all the slots. Why do you need terminators if the chassis is limited to only 5 slots and all the slots are occupied??? Thanks, Ram

Apollo stuff

by compoobah＠valleyimplants.com

The keyboard on my 425 is a beige, model # 007121 by Apollo, working just fine. Not sure if this is "new" or "old", but it definitely predates the machine (has a D-9 to DIN cable, so later than the modular jack kbds) Where's Bob's stuff at? It would be really nice to get the docs to Al, I'd be willing to try to talk to HP to see if any software (tape images) can be made available publicly. Don't know if I can keep much equipment, though. 10.4.1 is very desireable, it improves SCSI support. I'm trying to cobble together a diff for SAU11/(10.4-10.4.1) from 2 disk images I have. Patches (including the y19.97k bug) are available from HP http://www1.itrc.hp.com/service/patch/wrap.do? pageKey=patch.jsp.archiveJump -Scott Quinn

HHC Basic memory problems

by dbetz＠xlisper.mv.com

I think I have this problem figured out. The RL-H1400 has only 4k of memory. If you press the I/O key after a cold start you'll find that you have around 3123 bytes of memory free. If you then enter Basic and type in a one line program, say: 100 print "hello" and then press the clear key to get back to the top menu you'll find you have only about 2 bytes free. If you try to reenter Basic you get the error message about not enough memory. You'll also notice that the filesystem has a file called "B". That must be the Basic workspace. It seems to take up pretty much all of the available memory and it is why you can't create any more files after having run a Basic program. The solution seems to be to type the "bye" command to exit Basic rather than just pressing the clear key. This must free up the workspace before exiting. If you do that after having typed in the one line program above you'll find that you still have around 3098 bytes left. You should then be able to reenter Basic and select the file you saved the last time and run it again. So, it looks like I have Basic working. I still haven't been able to find any information on SNAP though. I have seen some references that suggest that only the SNAP runtime is built into the HHC. Apparently, development was done on another machine. I would still be interested in finding a description of the SNAP language and maybe documentation on the runtime if anyone has any. David

Early machines from the 'workstation wars', Apollo and Tektronix come to mind, may be of interest in the future. There doesn't appear to be much on the technical doc or software side around for these. I tried contacting they guy who was working on the Apollo port for NetBSD to get the tech info he was able to collect, but got nowhere. People seem to have saved the later SGI IRIS (3xxx series) though, probably because of the neat graphics demos.

Sam's Photofact question

by chrism3667＠yahoo.com

Years ago I obtained from a library an edition based on a Mitusbishi floppy drive, model number I believe was 4151 but I'm not positive. Can anyone clarify this for me, a search proved fruitless. Does anyone have this manual? It's of interest because my Tandy 2000 uses Mitusbishi 4153 drives, and doubtless there's similarities. __________________________________ Yahoo!

11/45 progress & questions

by jwest＠classiccmp.org

Got the 2nd rack attached & cleaned up, as well as installed an 861C power control module. It's ready for the BA11 and then the other peripherals. Of course, when I went to get about mounting the BA11, I realized I have the inner rails (still bolted to the BA11), but I don't have the outer rails. These rails look exactly (to me) like the 11/34 mounting rails, with the pull-forward-and-the-box-tilts-setup. I've heard these 11/34 type rails are unobtanium. So, does anyone have spare outer rails for those type if rails - or any suggestions as to other ways to rack it up? I took the inner "tilting rails" off the BA11 to see if any other slides I have might work (but not tilt of course) and the holes just don't seem to line up in any good way. Thoughts? I have truckloads of RA81 slides spare :> The DL11 controller has a crystal that does odd baud rates, the only usable one by any of my terminals is 110 baud (I think the crystal in it is like 408.xxxx or somesuch. I read in the docs that you can use a different crystal and get more "common" (and higher) baud rates. The docs tell me what speed crystal to get - but is this crystal something I can just order from jameco/digikey/whoever and plug it in? The docs sound like it is only a crystal swap required. Correct? Thanks for any advice! Jay West

I'd think it could keep up with 110 Baud though. Most teletypes have some way for a signal from the computer to throttle the paper tape read ( as I recall ). You might look at connecting some handshake. You didn't state if it was making mistakes from the first character or if it read several right and then lost it. If it read some right, how long does it go before it makes mistakes? Any line feeds involved? Dwight

TSX and RT11 clones

by aek＠bitsavers.org

There was a discussion of cloning various PDP11 OSes a while back (2003) Google for "a PDP-11 question" as the subject. Someone with the handle of 'paramucho' had sources to a clone he had written. There was also someone who popped up around new years a few years ago claiming to have had one written by someone in Canada.

Power and the RA82

by fireflyst＠earthlink.net

My DEC dealer has a RA82 he wants $200 for, and I was thinking of trading him one of my RL02s for it. That's what actually came in this chassis, but I'm really concerned about the power requirements of the disk and controller - I know the KDA50 is a pig, but I do have a separate expansion box for it. My real concern is blowing a breaker in my apartment building. Now, I've read the current surge draw on a RA81 (in the RA81 user guide) is 35A in 110V mode. Is this correct? Also, what are my power bills going to look like running this thing 24/7? A already run one RL02 and the CPU 24/7, and I'm talking about adding an expansion box to it with the KDA50...will I be OK on one 15A circuit? Logic with these numbers says no, but I saw somewhere on the web where a guy said he was running an 11/750, RA82, and some other stuff all off 1 15A circuit. The only way I can see this working is if the drive spins up somehow by trickle charging a cap(or more than just 1) and then spinning up the drive. Can anyone shed any light on this? Will I blow something with this RA disk on my setup? Thanks Julian

Hello, Another box dug up from the pile ;-) This time its DataViews 8.0 for VMS 5.3. Seems to have been hardly used and includes the installation TK50 tape complete with manuals. I am not sure what kind of software this precisely is, but it seems to be something like "a Real-Time Graphical User Interface and Data Visualization Tool" (that came from the net somewhere). Anyway, its up for sale or swap, if interested just simply make me an offer. Stefan. ------------------------------------------------------- http://www.oldcomputercollection.com

Commodore sx-64 keyboard cleaning

by florit＠gmail.com

Hi, continuing the saga of the no worky sx-64 keyboard, I found these instructions. I will be reseating the chips in the sx-64 and following these steps- hopefully the bladder won't be ruined in the process. From http://personalpages.tds.net/~rcarlsen/cbm/keyboard.txt --------- THE SX KEYBOARD: DISASSEMBLY AND CLEANING (from the SX64 article) This keyboard is completely different than previous CBM designs. Therefore, some of the previous information in this article will not apply. You need to know how this one works to be able to safely take it apart for cleaning. The main component is a conductive rubber bladder separated from the PC board underneath by a white or grey plastic sheet with holes in it. The plastic sheet is an insulator. Until a key is pressed, the insulator holds the bladder away from the PC board contact points. If the insulator gets damaged or distorted, some keys will not work or may make contact all the time. Removing the bladder from the PC board requires great care. The insulator tends to stick to the board near each contact point. If pulled away quickly, it will most certainly be torn. I use a dental pick to slowly nudge the tiny areas that stick as I gently pull the bladder off the board. The last one took me about 10 minutes to remove. That work cannot be rushed. Some areas of the elastic insulator deform as they pull loose and must be pushed back into place before reassembly. The keyboard comes apart for cleaning by pressing in on the four plastic snaps on the front edge while separating front and rear panels with fingers. The two center ones are easy... just press in and up on the brown plastic top panel and it will bend upward. The two side snaps need a bit of pressure... use a small flat tool like a screwdriver blade inserted into the slots to make them release. With the top off, the keyboard is visible as several rows of keys over a conductive rubber bladder, which in turn is mounted over a PC board. Each key plunger assembly can be removed for cleaning if one or more are sticky >from a spill. They would -all- have to be removed to gain access to the PC board under the bladder. None of the keyboard parts are interchangeable with a C64. Note that the shift-lock key is not a latching switch as in a C64 or C128, but a momentary contact pushbutton like all the rest. A circuit in the SX forms the "latching" device and an LED on the keyboard key comes on when ShiftLock is on. The following is a report from a fellow user who sucessfully cleaned his SX keyboard: "I am pleased to report complete success with my efforts to clean the key pads on my SX64 and the keyboard is working like new again. Although not a terribly difficult operation, care must be taken. After removing the upper keyboard case half I removed the five screws along the front of the circuit board that holds it in place. I then removed the two screws holding the keyboard cable connector in place. At this point I removed the keyboard from the lower case half and removed the keys one at a time by pressing the two tabs together from the back side of the circuit board that hold the key assembly in place. I didn't bother to keep the keys in order as I would use a C64 keyboard as a guide when replacing the keys. I then removed the two tiny screws that hold a small strip of metal to the black rubber like bladder on the right side. At this point I was ready to lift the bladder from the circuit board. Under the bladder is a grayish colored membrane that is somewhat fragile and care must be taken not to tear it. On several occasions this membrane stuck to the circuit board as I attempted to lift the membrane from the circuit board. I used the tip of a very small thin flat screwdriver to ease the membrane off the circuit board when it would stick. Once the membrane was removed I cleaned all contact pads on the circuit board using cotton swabs (Q-tips) and alcohol. I also cleaned the contact areas on the bladder in the same manner using VERY LIGHT pressure. I replaced the membrane onto the board and attached the metal strip with it's two tiny screws. I attached the cable connector and mounted the board in the lower case half with the five screws. Take care not to over tighten the screw that goes through the bladder to avoid damage. After the board was secure in the case half, I replaced the keys. They simply press into place. The space bar will require a little care to line up all three connectors. Replace the upper case half and that's it. Not that difficult but very time consuming and it does not pay to hurry. While the key assemblies are off the keyboard it is a good time to clean the keys themselves and to blow any dust or debris from the underside of the key. If you find this information useful please feel free to pass it along to others." Charles Houck All I have to add to what Charles has said is some cautions when cleaning the contact points. Never use anything abrasive on the bladder. The black dots are the contacts. They are just a conductive coating on plastic, so rough treatment can easily destroy the bladder beyond repair. A -light- rub with a dry Q-tip is all that is needed on each black spot. For the copper keyboard contacts, I use a #2 pencil eraser to remove oxidation from each contact point, then rub each with a dry Q-tip to "polish" the surface. The resulting contacts should be shiny with no spots or blemishes. I don't use solvents unless the board and/or bladder is contaminated because of a liquid spill. --

Hi There is nothing particularly significant or historic about this particular machine. It is too bad that it will most likely end up being sold for scrap. A museum may want to buy it but it is generally like many current PC's. It is too new to be of particular interest and is too obsolete to be particularly useful. A school might find it useful. I'd like to have the machine but I tend to like to collect useable machines. It would just be floor space to me. Surely a conversation piece but that is about all. Dwight

Altair 680B Toggle Switch Style?

by bill＠timeguy.com

I tried to post this once before, but I never saw that it showed up, so here goes again... I'm trying to build a replica of a 680B using a real 680B case from eBay, authentic switches and LEDs, and a power supply and CPU board of my own design. I've seen both flat- and round-handled toggles in pictures on the web and my old issues of Byte magazine, and have been unable to discern a pattern to it. Can anyone on the list tell me why the difference, and which one is more accurate to use? Thanks.

Commodore 64-sx Keyboard getting stuck?

by dwight.elvey＠amd.com

Hi That sounds similar to the keyboard on my Sun at work ( the one I'm typing on now ). About 3 years ago, I spilt Dr. Pepper on it. It immediately stopped working. I took it apart and washed the layers one at a time and dried them. It is still working today. I can imagine that replacing missing traces would be a little more difficult. I'd think that the current through most of the wires is quite low and one might try using some of the repair stuff for windshield heaters. If that didn't work, a last resort might be to use some small wire wrap wire and melt a channel into the plastic layer to keep from deforming the stack of sheets to much. Just some thoughts.

Commodore 64-sx Keyboard getting stuck?

by florit＠gmail.com

Hi, I pulled out my 64-sx out of the box it's been stored with in anticipation of getting my JiffyDos upgrade installed into it. To my dismay, when I plugged it all in and powered it on, the keyboard wouldn't work properly. Any of the keys have to be pressed multiple times (3 to 10 times) in order to get the character to show up on screen. Any suggested remedies? I'm wondering if the keyboard contacts are just a little dirty and need a little cleaning, but I wanted to check with the gurus before prying it apart.

DEC Microfiche question

I suppose you have to position it manually for each page. nope. it should be step and repeat for the entire sheet, once I understand how to set up all the parameters. the device is not a fiche reader with scanner bolted on. it is an x/y table with adjustable lens and imaging array. there's a pci motherboards buried inside running DOS, which we backed up a couple days ago. here's a picture of one (it's a LOT bigger and heavier than it looks...) http://www.cadcam.org/pscnmekel.php > How many sheets do you have waiting to be scanned? thousands..

DEC Microfiche question

by aek＠bitsavers.org

Pardon my ignorance - but some of the sheets in the manual are horizonal/large. Were the fiche images larger or did you have to enlarge them? (I have some fiche - but they are all the same size images). -- Computer Output to Microfilm (listings and such) will have the same size frames, but documents might not, since they have foldouts. This particular document was all post-processed by hand, scanning oversized frames and cropping to 8x11 or 11x17 effective size. It took about two hours to reformat all the scans.

wild and possibly idiotic idea- what do you think?

by compoobah＠valleyimplants.com

The recent discussions about unsupported software led me to think about old O/Ss in general. It seems that possibly one of the reasons that companies are not releasing them is due to the amount of work involved in contacting all the other groups who licensed bits to the software (e.g. AT&T for UNIX) (I have no idea how these agreements were set up, so it might not be an issue, but . . .) Anyway, to the point- perhaps if some group were able to decide on a list of systems they really want to see available, and secure the permission of other interested parties, then we could see some of these older software available for free to hobbyest users (stuff like DOMAIN/OS/Aegis, older MCA AIX, IRIX). I know that in some cases (PERQ et al.) it will be difficult to figure out who to contact, but some we could just read of the copyright screen. Enough drivel, dumb idea or not? -Scott Quinn

Another DEC KL8-AA Question

by rigdonj＠cfl.rr.com

FIRST. This is NOT the panel that I was describing in my earlier question about the KL8 stuff. This is an entirely different panel. Does anyone recognize this panel? It's marked KL8-AA M8319 on the back. But it's marked by hand so that may not be accurate. It has two ribbon cable connectors that I'm guessing connect to one or two M8319 cards. It also has eight Mate-N-Lock connectors marked J2 through J5 and J7 through J10. It also has eight DB-25M connectors marked P1 though P4 and P5 through P8. Just as a guess I'd say that it can use the cables with the Mate-N-Lock connectors or cables with DB-25F connectors and it looks like it can handle a total of eight serial data lines. Anybody know if that's correct or what machine it's for? Joe

Nice Xerox 820 System...

I actually have one of these and wondered what it was. I rescued it from someone's front veranda a few years ago but have never fired it up. I'd like to give the drives a really good clean before I do but haven't got around to sourcing any documentation on this machine.

DEC KL8-A questions

by rigdonj＠cfl.rr.com

I picked up a panel that's marked for the KL8-A. I know the KL8-A is a Multiple Serial Line Unit for the PDP-8 but I'm not sure exactly what I have here. The panel is 19" wide and is a deep U shape. It has eight H 319 A units on it. Each H319 has a short (18"?) cable coming out of it that terminates with a Mate-N-Lock connector. I also have two cable sets with four small cables (~8' long) in each one that all connect into two 50 pin Berg connectors. The other end of each cable has a 10 pin (4 used) Mate-N-Lock connector that's connected to one of the connectors from one of the H319 units. The other side of the H319s also has a Mate-N-Lock connector but I don't have the cables that connect to them. Q1: What exactly do I have here? Q2: What are the H319 units for? Q3: Anybody have the pinout for the outputs of the H319As? I'm guessing that the Berg connectors connect with two M8365 MSLU cards and that the H319As convert the current loop outputs to RS-232 to give 8 RS-232 outputs. Joe

Hi list, I could grab this if anyone wants it (and can collect it from me soon - I don't have any space to store it, which is why I haven't grabbed it so far).

If anyone wants this, please let me know SOON (including a definite date when you will pick it up from me) and I'll go out and grab it. Don't know anything about the condition of it, I'm afraid.

Dear Joe R Good morning For Z8002 you need Compiler or technique to use it, I have so many Z80 , I try to use it in the begining , but then I shift to 8051 and Atmel AVR microcontrollers, its fine. At tat time I have Cd with compilers for Zilog , If I will look again I may get it again. I worked a lot on microprocessors system. Also I removed these Zilog ICs from some big PC Bords >from scrap. I think some place I have the pin configration and instruction set for Z8002. Also If you want to exchange two three pieces of Z8002 with Z80s then I may also try. Micro controllers have benifit that no connections are required, but they are slower then microprocessor system Regards ZahisZolo __________________________________________________ Do You Yahoo!?

Make a New Mylar Keyboard, was Re: Commodore 64-sx Keyboard getting stuck?

by marvin＠rain.org

Since I suspect that the keyboards were originally done by silkscreening conductive ink onto mylar, it should be fairly easy, albeit time consuming, to make a new mylar. My guess would be to use something like a Houston Instrument Pen Plotter that would also take a vinyl cutting knife, cut out the mylar, make up a screen, and just silkscreen the traces onto the ready to insert mylar. Or, if the old mylar is not broken, just reuse the old one. I don't know what kind of prep needs to be done in order for the ink to adhere to the mylar, but this (and anything else that comes up) is something that has been done for a long time. Another thought would be to go to someone who already produces this type of switch and find out what it would cost to make up a couple. It might be possible (depending on the size of the company) to get it done gratis, ie as a sample. > On 7/11/05, Dwight K.

WOW!!!! $15k DEC PDP-8 CLASSIC MINICOMPUTER SYSTEM DIGITAL PDP8

by aek＠bitsavers.org

Not much 1000 stuff - I rarely even hear about it. 2000 (2500) is around, but rare. -- I think most of that came back as trades to SGI, or were field upgraded when they could to the 020 IP CPUs. Weird Stuff (was trying to remember when, probably late 80's) got SGI's trade-ins. I wasn't interested in that sort of stuff at the time. Did build a nice 31xx and wrote all of the disc contents to tape from what they had. Was a lot of fun stuff on those discs.. Even back then, there was very little 1000 stuff. The rarest were the 1000 attached graphics terminals running the Stanford V Kernel. I gave the SGI to someone.. probably long done by now. I remember running down to the Univ of Arizona to pick up a 3130 around the same time, and working on the SGI hardware FAQ. They really weren't very useful as a GP workstation, though, because of the way the frame buffer worked. Everything went through the graphics pipe and rendering processor, so you couldn't just BLT to the screen. They used Excelan enet cards so the TCP/IP had the usual problems (IP adr hardcoded, et. al.) Still have a bunch of print sets for the Multibus boards. Just waiting for the last of SGI to croak before putting them on bitsavers.

Some of our domestic RCD breakers can't be held in, but the normal MCBs on domestic mains distribution panels can. I used to hold in the 20A breaker on the circuit to my 19A UPS for a second or two whenever it was switched back on, because otherwise the switch-on surge tripped the breaker (class D breakers like we have in machine rooms at work don't have that trip problem). Oh, and if you don't think a 19A UPS is very big, remember it's 240VAC in the UK. That's 4.5KW, enough to keep quite a few RA82s running. -- Pete Peter Turnbull Network Manager University of York

univac something or other

by brian＠quarterbyte.com

Anyone know what this is? http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=7335084988 It appears too be a CRT terminal of some sort, but the box is pretty large, which is odd. Key to disk maybe? From the styling it looks like late 70's, early 80's? This is the item's second time up. I've written to the seller twice for more info but he's not bothered to respond. I'm curious to know if anyone recognizes this. Google didn't turn anything up. Brian

univac something or other

by GOOI＠oce.nl

Hi Brian, for a moment I thought it was an SSP, but the SSP would have some 8 inch floppy drives. IIRC the SSP (System Support Processor?) was needed to startup the 1100 series before you could mount a tape with a sysgen'ed bootable system. Unisus (Sperry) machines required a sysgen for every disk or tape drive or whatever. Very unlike PDP-11's which recognize what options are connected to the bus. But then again, an 1100 is quite a different league, as is EXEC, the Operating System. This is all very vague to me. Anybody, please feel free to correct me. So, I am not sure Brian. The SSP's I ever saw where alike, but then different :~) my 2c, - Henk, PA8PDP. -----Original Message----- From: cctalk-bounces at classiccmp.org To: cctalk at classiccmp.org Sent: 11-7-2005 20:27 Subject: univac something or other Anyone know what this is? http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=7335084988 It appears too be a CRT terminal of some sort, but the box is pretty large, which is odd.

Discrete Component FlipFlop

by dwight.elvey＠amd.com

Hi If they are JK's, you could make a divider connected to some LED's and use a 555 to run them. That symbol on them must be from some manufacture. These might have been fro some embedded system, such as an elevator and not necessarily from a computer. A machine I worked on in the service had a number of flop boards and other logic boards ( different form factor than yours ) but was not a computer.

international shipping

by chrism3667＠yahoo.com

Can anyone tell me the best way to have something shipped from say England or the Netherlands (or Germany). Or even Brazil/Argentina. Or even Australia. I know it's not ever going to be cheap, but when you calculate 20 or so pounds from S.America - $300+, I figure there must be a better way. For those of you who already don't know it, FedEx usually beats UPS by a mile at domestic postage. Perhaps half in alot of cases. But they don't cover as many areas as it seems UPS does. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

That is what I recall doing when I replaced the bad roller. I don't recall how I got the last little bit of slack out of the tape. I remember holding onto it with a ChemWipe to keep my finger oils off the tape but that only works until is gets close. One still needs to suck in the last bit of slack before putting it into a machine. Like I said, it was counter intuitive to pull on the supply side to get the take-up side to suck in the tape but that is what I recall. It wasn't until now, years later, that I thought about how it could work. Thinking about how the Bernoulli's principle worked with a elastic band helped to figure it out. The more stretched band at the take-up has to have a higher surface speed. It should be fun to confirm by the spool experiment :) It was a fun thought experiment anyway. Dwight

Replace roller rubber on HP 9825 tape drive

by vcf＠siconic.com

I'm trying to repair the tape drive in an HP 9825. The roller has melted (no surprise there). It seems like I could just get a bit of silicon tubing or something that has the same diameter and guage as the existing roller. I know this has been discussed before but I can't find any specific messages (by the way, the CC archive search is broken, Jay). Can anyone provide any tips or guidance so I don't have to re-learn mistakes already made? Any tips for cleaning off the existing material? Isopropyl alcohol? Any thoughts of using heatshrink tubing and applying multiple layers until it has the same thickness as the original roller? Thanks for any help. This will be a candidate for adding to the knowledge base once I've successfully replaced the roller. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]

repairing cracked plastic

by compoobah＠valleyimplants.com

I have had good luck (depends on plastic-see below) with MEK (Methyl-Ethyl-Ketone), works the same way as the dichloromethane, can be acquired in most hardware shops. It doesn't work very well on some of the "alloy" plastics (GE Cyclolloy? mix of polycarbonate and ABS. Superglue doesn't even work here-the plastic disintegrates into a mealy mush). Fortunately, that seems to be only used in newer Suns and PCs. Drywaller's Fiberglass tape might be a good strong inorganic reinforcer, or I sometimes use interfacing (a semi-fabric thing) when I repair books- might work for computers too. In books, it seems to grab the glue better than standard woven fabric. -Scott Quinn

WAS .... PDP-11/23+ and rx-02 drives, need help!!!

by g-wright＠worldnet.att.net

Thanks to everyone that took the time to respond. As the story goes Henk (My 11/60 buddy) was right on the money with the the board location. I started out there a Year ago but in time made the mistake of not following my notes and installing the board below the disk controller. The other problems where, none of the Blank "DEC labeled" disks will Format even now, but will work on a CPM machine. The drive looks for something very quickly and errors even in single density mode. I did get some new "DEC labeled" disks to work now. The other issues where that 2 out of the 3 sets of RK-02's where Bad and only 1 of my RT11 disks will boot. So I had a large hole to dig myself out of. All are working now. I just went through 10 sets of RK-02s and only got 4 going. Most have bad boards. It seems that the lower board is the worst with 5 bad. Most of these came from a Damp location. Someone else had them stored in a barn. I have tested these by swapping the boards into the working machines and using the boards from the working machines in the test machines. On the Hardware side, after cleaning and lubing all seemed to be OK. At least they could boot from either drive. Anyone had any luck repairing the boards ???? What effect does the moisture have on the boards ???? They where not outside just damp air. I have cleaned them with board cleaner and checked the switches for operation. Some of the IC pins are getting rusty. Are the IC's sealed very well or can moisture get in the chips Just think, I still have TE-11/16's and RL-01/02's to get going. Before MY 11/60's. Thanks again Jerry Jerry Wright JLC inc. ....>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> Hi, I'm trying to get one of my 11-23's going and finally got around to setting up a TU58 emulator. got it to boot RT-11 and now trying to get a RX-02 working. I have 3 controllers and 3 sets of RX-02's. All do the same thing. The just seems to not be able to find track 1 or Home or ??? The heads just keep going from home to maybe the first tack and back. The heads do load and the system tries quit a few times then pauses and tries again. It then errors on drive failure or read error directory not found, size function failed depends what I ask it to do. I have tried all of the boards and drives. all or them seem to do the same thing. I do not know how good the drives are but can't believe there all bad. I have recheck the switches in the RX-02 and the Jumpers on the cards. Cleaned the drives. tried different disks. Is there some kind of compatibility issue that i do not know about. Or do I have 6 dead drives. The system is a Micro PDP 11, 8 slot Rack mount, with 1 M8189 1123+ 1 M8067 KB 256k Memory 1 M8639 YA MFM rx50 controller 1 M8029 RX-02 controller in this order. Everything else seems to work.

Hmmm, now that sounds familiar to me. Is it a tiny little card? If so, it did indeed come with GEOS and you had to put it in the //e to get the mouse to work. The copy of GEOS I got at the time had a mouse included and had an option to get 3.5 disks which I did even though I only had 5.25 drives at the time. My copy of GEOS is around here somewhere and I got several other BS applications for it as well.

Talking of the 380Z...

by ard＠p850ug1.demon.co.uk

Since the 380Z seems to be popular at the moment, does anyone have info on 2 bits that are not properly described in the Information File? The first is the dual cassette controller. The pinout of the 7 pin cassette socket is given, as of course is the schematic of the VDU board that contains the cassette circuitry. The controller seems to contain a couple of relays to control the recorders (were these powered from the system 5V line or a separate power supply?) and switching to allow either one recorder to be used, or two with one used for recording the other for playback. It's possible to make some guesses as to how it was wired, but some real details would be nice The second is the SIO-2 board. This was a bit-banged serial port using, IIRC, 3 lines of the user port. 2 ouput lines for TxD and thr reader control relay, one input for RxD. At least knowing what port bits were used would be a help... -tony

Discrete Component FlipFlop

by marvin＠rain.org

Our annual Bazaar was held today with all the leftover stuff now at my house ... briefly! In searching through the stuff this afternoon, I found several boards that I couldn't identify. One is labeled "FlipFlop" and the other "Inverter". I put up a picture of both sides of the FlipFlop at: http://www.rain.org/~marvin/flipflop.jpg While not obvious from the photo, it does look like the board has gold plated traces. Does anyone know what these things might have been a part of?

by cc＠corti-net.de

Hi everyone, I am still looking for information about an IBM card punch which I thought was some variant of an IBM 029. I've found out that this must be an "IBM 545 input output card punch". So, has anyone any information about this punch? (Pictures are on http://computermuseum-stuttgart.de/dev/tmp/ibm029.html) Christian

The small difference is the console IOTs are differently assigned but easily fixed in the code. Its the side effect of their IO devices. Allison

IBM Punch Cards

by jrkeys＠concentric.net

Well pulling out my Hero-Jr robot for some photos I noticed the two card sample booklets I go a few weeks ago. There seems to be over 300 different card stock samples in the two salesman booklets. One is called "general Purpose Card Sample IBM Data Processing Cards" form # 570-0275 9-67 and the other is "IBM Standard stock card formats" form # 570-0440 from around 1970. I had no idea of all the many card formats IBM had.

11/45 is alive (I'm singing "who's johnny")

by jwest＠classiccmp.org

The /45 lives, got a console up with the console emulator today. I never did get a blinking lights program to show up right, but I'm too embarassed to admit what likely caused that. But I got a lot of other few instruction programs to work correctly so I moved on to the DL11 and 9312 setup and got it all working. Only have 8K of core, but hey, it's a start. Once I get it to boot from a peripheral I'll take out the loaned cpu set and move mine back in and see where it chokes. So now I have a few peripheral questions. I was going to put in an RL02 drive, but I've been advised against putting one in the same cabinet as the cpu cab is top cooling intake :\ Now I'm moving on instead to hooking up and testing a LincTape II and a DSD440 drive. I found the docs for the DSD440 drive on bitsavers; my drive is missing the controller to drive cable. From those docs it appears to be a straight through 2x13 pin berg connector at each end. Can anyone confirm this? Also, If the DSD440 drive is set for RX01, will it work with the standard dec boot rom (DX) on the 9312? Likewise, if it's set for RX02 emulation will it work with the DY boot room on the 9312? Or does the DSD440 need a unique bootrom? I also have the LincTape II & controller (&cable), model CO-3000D. However, I don't see any docs for it on bitsavers and my googling gives tons of stuff on the Linc, not the LincTape II. Does anyone have docs for the LincTape II in electronic format? Or better yet... a boot rom for it :> I have spare boot roms (DP, RP02/03 and DM, RK06/07) that I doubt I'll ever use and would be available for trade. Thanks! Jay West

RA81 slides??!##@$

by jwest＠classiccmp.org

If someone knows the magic to pull a RA81 out of a rack and off the slides completely, I'd love to know it! I have two in the other H960 that someone mounted backwards in the rack :\ I pull the drive about halfway out and to get it further, flip up the "rocker" catches under the rail. Then it comes all the way out and clicks to a stop. Most rails I've seen... you have to get them about 3/4 of the way out and then a screw will appear in a hole that you have to take out. These slides have that hole but the screws are already out. What obvious trick am I missing? Jay
