cctalk Digest, Vol 2, Issue 13

by Joel.E.Bradley＠syntegra.com

Is there actually a demand for these kinds of things anyway? I happen to work at the company known as the former CDC and we have a lot of this stuff around...in fact, we still support a lot of it. The Cyber 675 is still in use! Would this stuff be worthwhile trying to rescue from the 'scrap heap'? I also have lots of CDC branded merchandise...

VCF 6.0 pictures

by classiccmp＠vintage-computer.com

I added descriptions to the pictures and integrated the VCF 6 stuff with the rest of my site. Feel free to check out www.vintage-computer.com/vcf6.shtml and please let me know what you think, especially if I missed something, misidentified someone or otherwise messed up. The show was truly awesome this year. I can't wait to hear the attendance numbers from Sellam. I'm pretty sure records were broken. The displays were amazing, as always, and the computers were incredible as well. It's fun to realize that you were in the same building as 3 of the maybe 30 or 40 remaining Apple Is in existence. There were two equally rare Mark-8s in attendance and several other machines that you just don't see every day. Thanks! Erik Klein www.vintage-computer.com/vcforum The Vintage Computer Forum

repainting plastic terminal parts

by ian_primus＠yahoo.com

I recently got an old Adds Regent 30 terminal (it says "Honeywell" on the front, must have been rebadged). I have repaired the electronics (I took pictures and documented the process, I'll put it on my website when it's ready), and the terminal works now. It was extremely filthy, however, and I cleaned up the outer shell with a little windex with no problems, but the brown plastic around the monitor and the keyboard was very sticky. I tried cleaning the plastic around the keyboard with just plain water, and with Windex, but it was still very sticky. I tested some Goo Gone on the back of the part, and it didn't damage anything, so I used it on the front. It appears that the paint is coming off. The Goo Gone made it come off a little, and I noticed that on the rest of it, just rubbing it with my finger could cause the paint to come off. It appears that whatever grime got onto the terminal ate away at the paint, as the paint on the inside does not have this problem. Here's my question - what is the best way to go about painting things like this? It was originally a dull finish (I think), do they make spray paint that has similar properties? Does it come in "Honeywell Brown"? Has anyone had experience painting plastics, or repainted any computer cases before? Any help would be appreciated. Ian Primus ian_primus(a)yahoo.com

If so, I have both parts but just > need a cable. Sounds plausible. Mine came on its own, no cables, no drive, so I'd be interested to know what's "inside the box". I assume an ST506 drive, a PSU, a Xebec card, and probably something to connect a ribbon cable to. Is there a connector on the outside of the drive box? If so, what type is it? We could probably work out the pinout required. -- Pete Peter Turnbull Network Manager University of York

identify this ISA card?

by pete＠dunnington.u-net.com

This one's barely on-topic, as it has a silkscreen legend which states "(C) 1992 GSM-SYNTEL LTD". Above that it says SYN-PC302. It has a couple of Actel FPGAs on it, and space for another similar-sized IC, three 75160 interface ICs next to a 26-pin male box header, spaces for 8 ZIP devices (RAM?), and spaces for two miniDIN sockets (an 8-pin and a 9-pin). Anyone have any idea what it might be? -- Pete Peter Turnbull Network Manager University of York

Interesting video board....free!

by geneb＠deltasoft.com

In cleaning out some of my old stuff, I ran across a Diamond Stealth 64 PCI VGA card. What makes it interesting is that it's got a full size 15 pin d-sub connector instead of the 9 pin size, high density 15 pin d-sub connector. The chipset is an S3 Vision968. Anyone that's interested can have it for the cost of shipping. g.

Roland LAPC-1 Card

by kbudd＠solace.net

Hello. I just ran across a message where you were asking someone else if they still had any Roland LAPC-1 cards. I have one that has been on my shelf for years. Do you want it? As far as I know it works, but it hasn't been in a PC in over 8 years. I'll mail it to you if you'd like. If it works, you can give me whatever you think it's worth. If not, you can just have it. :-) The board has the following inscription on it: MODEL LAPC-I ROLAND ASSY 75420300 00 MADE IN JAPAN Let me know! -K.C. kbudd(a)solace.net

Floppy drive alignment tools

by GenealogyPro＠RicVa.net

Can you identify any sources for floppy drive alignment tools similar to Floppy Tune that was put out by Data Depot of Clearwater, FL? That company tells me its product has not been available for more than a year and it is not certain when, if at all, it will again become available? With what I recall I paid for the same, it would be worthwhile to buy either another copy or a competitor's produce since the drive I need to realign is in a laptop computer and thus would, unless I could find a "junked" computer with the same floppy drive that still works, cost as much to replace as what I originally paid for the laptop itself as I bought it used.

It's more than a souped up 11/780, but I guess in this company it's a fair description. :-) If noone goes for it, I'd love to get my hands on the cards (especially memory). Update have one 8650 up and running 24/7 with NetBSD. I'm about to embark on an ambitious project of getting the device driver from Ultrix working in NetBSD, if someone else feels like joining in... Does anyone have any good ideas what the problem can be if an 8650 have problems booting the FE, by the way? It fails about 50% of the time. I've checked all cables, tried two different FEs, tried different RL02 drives and packs. Different controllers. When I get an error, it's a problem with the RL02. That much I can tell >from the error, but unfortunately, that specific error is actually not mentioned in the DEC documentation for the 8650. The only thing I just realized I haven't swapped is the Q-bus backplane...

If you're running them as a LAVC (Local Area VAXCluster, used to be any cluster using Ethernet instead of CI) then this was done all the time and I'm sure still is. They probably haven't called them LAVC's for years and years, though. If you're saying you're going to interconnect the backplanes per the discussion here and in MicroNote #26, then if people did it it was a not a very common thing. And as others have pointed out, the normal OS candidates won't have support for it. That's not a reason to stop the project, just be aware of the necessary effort. --S.

From a motorcycle list that I'm on. Please respond to: one2dmax(a)aol.com Hello guys, I have a ton of electronic stuff and will probably never use it. There are hundreds of semiconductors, chips, diodes, ect... in the lot. I originally purchased the stuff for the storage containers. I'm sure some of this stuff has some value though and hopefully one of you has a need for this stuff and can make me a fair offer. Contact me off the list for pictures and offers. I have no idea what it is worth so try to be fair with me. I think some of it went to a training kit and other stuff goes to an auto repair kit as I had a manual that came with it.

Moving- stuff must go

by ccmp＠ovay.com

Hello. I' in the process of moving, and the storage space I thought I had did not materialize, so... If there is anyone in the southeastern MA/RI area that can pick up some of these machines, they are yours for the taking (mostly Tandy 1000 and Apple stuff). They are located in Taunton, MA, but I can also bring them to Fall River, MA, where I now live. I only have about a week tops to get rid of this stuff. If anyone is interested but can't pick the stuff up in a week, I may be able to hold on to it for a short while longer. Unfortunately, I won't be able to ship anything at this time. You can view the list of stuff at http://www.ovay.com/list.txt and I'll be updating it when stuff goes. Email me at ccmp(a)ovay.com and I'll get back to you. Thanks so much for reading this.

Has anyone on the list ever worked with, built, or seen such a beast? Did any interesting OS research projects of the time use this feature (I'm thinking V or Mach)? --S.

Fwd: Non Tech - Selling electronics gizmos

There are hundreds of semiconductors, chips, diodes, ect... in the lot. I originally purchased the stuff for the storage containers. I'm sure some of this stuff has some value though and hopefully one of you has a need for this stuff and can make me a fair offer. Contact me off the list for pictures and offers. I have no idea what it is worth so try to be fair with me. I think some of it went to a training kit and other stuff goes to an auto repair kit as I had a manual that came with it.

Giveaway Schtuff

by zmerch＠30below.com

AFAIK, everything's on topic, but if not, oops... Been doing more basement cleaning, and have some stuff for giveaway (with more to come). Cost: Cost of actual shipping. =-=-=-=-=-=-=-= MicroSoft Visual C++ Version 1.0 SDK manuals (all of 'em -- comes up about kneehigh to me!) - Cost could be prohibitive via UPS, but at least in the USA, Postal Service "Book Rate" should be affordable, even if it takes a while... =-=-=-=-=-=-=-= OS/2 Version 2.11 on 3.5" Floppy - Still Shrinkwrapped!!! Communication Manager/2 for OS/2 Version 1.1 - still shrinkwrapped, but one corner is 'torn' - you can tell it's never been opened, but the shrinkwrap has seen a few better days... ;-) =-=-=-=-=-=-=-= Atari 800xl (works) with another 800xl (parts, not tested...) This comes with some software, but I have no clue what... I believe I have power supplies (I found 4 so far, but not sure which ones are for the 800xl's... 1050 disk drive, CX-85 numerical keypad, XM-301 modem, and other assorted indescribabibbles... ;-) I can throw in a joystick or two, and I think I have a set of 'normal' paddles (not the ones that came with indy racing...) I'm still looking & sorting, so I dunno what else I have Atari 8-bit based, but you can get the whole lot for shipping... ;-) =-=-=-=-=-=-=-= That's all *for now* - anything not claimed in 7 days will be dumpstered or epayed - it's gotta go...

12 bit S-100 memory card ????

by rigdonj＠cfl.rr.com

Found this in a pile of scrap boards today. It looks like a S-100 memory board but has 2 banks of 12 memory chips. The chips are AM9016EPCs which I think are 16k x 1 DRAMS. Also there's no 5 volt regulator or address jumpers or switches. It appears to be a 32k x 12 bit memory card for a S-100 system that has built in 5 regulation and at a fix address. Anybody have any idea what system it's for? The only markings on the card are what looks like an overlapping C and H with the opening on the C facing down instead of to the right. The H is below and to the left of the C. Joe

Erasing Eprom by using UV-Led

by A.Haunstetter＠VR-Web.de

Hello Mr. Shannon, in the topic "A way to erase OTP components?" I read that you succeeded to erase windowed 27C512 using a UV-Led. Because I'm about to build a combined Programmer/Eraser, where erasing shall be done with UV-Led, I like to ask you about your experiences. What type of Led do you use? How long do you need to erase? What was the distance between Led and Chip? Did you made Test with other devices? I hope you take a little bit of your time to answer me. With best regards Adrian Haunstetter

What HP OS could it be??

by rhudson＠cnonline.net

Ok HP experts out there One saturday my programming class in high school went on a field trip to Santa Clara University. We got to try out some of the minicomputers there. I asked the people who were with us if I could come back and use the computers any other time, they said "sure as long as you don't get in anyone's way", so for almost a year, in the dark morning hours I would go down and program in fortran.. using the card punches and seeing my output on the line printer. What OS was I running? Here's everything I remember: HP2100, Card Reader, Beehive CRT terminal, Line Printer, Flat-slip in horizontal cartridge disk drive/with fixed platter, Paper tape punch and reader, and a plotter The machine was in the engineering department of University of Santa Clara, in around 1976 Jobs were written in Algol or Fortran, and punched on cards. Job control cards had //somthing blah.... The boot loader was stored at (i think) 102077 (punch this in the switch register and hit run???) What was I using?

Re. HP64000, aka offering help to duplicate HP64K disquettes

by Bissonnette.Michel＠ireq.ca

Hi! I was brousing the web to see if something new on the web related to that good old HP 64000 beast. I collected HP64K related stuff since 6 years and I have about 60 Manuals titles and 40x 5 inches Floppy softwares disk for it. I Have been faced to the problem of preserving the files on those old originals Floppies. With the time I found a software for that usage and wrote a procedure to duplicates the diskettes with a PC. I will be glad to help anybody who wish to preserve that heritage especially if you can offer something for trade. Ex. Cards, pods, accessories, manual, software diskettes, expertise, etc. Michel B.

Any background > material on the 64000 would also be appreciated. You may have yelled just in time. At one point I had (5) of these things in my garage. Most of the extra hardware is gone (although I may have one or two extra pods), but I did hang on to a large box of documentation and have all the latest-and-greatest software on diskette. I was planning a trip to the landfill, but will hold off on that in case you want any of it. If you are located within driving distance of Burlington, VT, you could also cart away one of the floor-standing 8" hard-disk units (weighs > 100lbs. and stores a whopping 5-MB). I wouldn't even consider shipping that beast. Let me know if you are interested in the docs. The diskettes would have to be duplicated, which means finding time and space to fire up the remaining system unit and remember how to use it <g>. Perhaps someone on the list knows of a utility which permits copying the HP64k diskettes on a PC? Steve

Help! need 400k/800k Mac os 6 or 7 diskettes!

by cb＠mythtech.net

>It takes more than ROMs. The SE originally shipped with the original >IWM floppy controller, which cannot handle MFM disk format (either 720K >or 1440K floppies). To use the Apple Superdrive (FDHD) 1440K drive, >you need BOTH the newer ROMs and the newer SWIM floppy controller. Then does that mean there weren't any 3rd party 1.4 drives that could be used on the 800k SE? I thought there were. Although maybe they were and used SCSI, or their drivers just had a way to get around the floppy controller short comings. -chris <http://www.mythtech.net>

Help! need 400k/800k Mac os 6 or 7 diskettes!

by cb＠mythtech.net

>Was there such a thing as an external 1.44 drive? If there was >could my SE use it? Yes, and maybe. The ROMS in the SE dictate that it can't use more than an 800k drive. So a standard external 1.4 drive will still only operate as an 800k drive in an SE that doesn't have the newer FDHD roms (if it works at all). However, I do believe there were drives that had special drivers that let the SE use 1.4 disks. I'm just not sure of brands or availability. -chris <http://www.mythtech.net>

LK201 key stuck

by chd_1＠nktelco.net

I have been working on a DEC Pro 380 and the LK201 keyboard I have causes the Pro to report a stuck key and hang. So I opened up the keyboard thinking I could clean out whatever had jammed in there. Looking at it, I don't quite know how this thing works. Each key is supported by a "cantilever" spring. This spring has a piece that looks like it has a contact of some sort, but this is all on top of a layer of rubber and it doesn't even look like the "contact" touches the rubber. Below the rubber is a piece of clear, flexible plastic with circuits on it. So does anybody know how this thing works? Contacts? Capacitive? Inductive? Has anybody ever fixed one? -chuck

ASR33 Teletype interfacing

by tomj＠wps.com

>I have been attempting to get my ASR33 teletype connected to something >and communicating, but so far I have not been successful. I have built >the interface here : >http://www.daedalus.co.nz/~don/computing/20mahack.html It wont work, sorry... Teletypes are inductive loads. Though they only want 20 mils, the voltage needs to be high to get the initial magnet pull-in (basic RL theory). ASR33 loops were generally run at 100V or so, but I run my Model 28 at 14V, with non-perfect error rate, and I don't use the keyboard. The keyboard and printer are IN SERIES. If you hit keys while it's printing you foul it up. Normal. Because it's inductive, it makes a spike when yuo turn the voltage off. You need to suppress this with a diode, a resistor and capacitor, for example. They're not subtle interfaces, and weren't meant to be. If you just want to print, you can rig up a power transistor, two resistors, a diode, and a high-voltage DC power supply to do the trick, and drive it from the serial port. If you want to receieve also, you can use another transistor and resistor to pick off the change in loop current that happens when you press keys which open the loop, and drive the serial port. I've done one of these fairly recently, and if poked with a not-too-sharp stick, I'll scan the schematic and pu on my website.

Last call: 7" 9 track reel tapes

by cb＠mythtech.net

Last call on 7" 9 track reel to reel tapes. They are labeled as "Endura 800 BPI to 6250 CPI BASF". All have data on them, none will be erased before shipping. I have 3 cases of 24 left. A case is $8.00 to mail in the USA via Media Mail rate. I had been asking $10.00 for a case plus shipping ($18.00 total for 24 tapes, so less then a buck a tape). If I get no takers, they are going in the trash, so I'm open to offers on their sale price. And for you googlers that are going to see this posting 6 years from now and ask... this is dated 10/10/03, and the tapes will be in the garbage by 10/13/03... so if you are reading too much later than that, don't bother asking, they are already gone. -chris <http://www.mythtech.net>

Box of assorted chips available

by cb＠mythtech.net

I've got two small boxes of assorted chips available. I have NO idea what all they are. They are just random pulls from motherboards and cards and things like that. There may be CPUs, or bios, or cache, or ram, or FPU, or who knows what. Nothing is of the "current" genre, that's why I'm offering them here (almost all should be 486 or earlier era stuff, with lots being 286 era). Not all the chips are in great shape, and none have been carefully handled or packed. They have all just been tosed into two Priority Mail video tape boxes. So pins might be bent or otherwise damaged. If anyone wants them, just cover the postage (plus my buck for gas/paypal). -chris <http://www.mythtech.net>

5.25" floppies available

by cb＠mythtech.net

I've got a large pile of 5.25" floppies available. These seem to have no resale value on ebay, so I'm offering them here. I've got some that are labeled as HD, some as DD, and a huge pile that are not labeled at all (which I know some are HD and some DD). All the disks are used, and most have labels with writing on them. Some have multiple lables stacked up, some have write protect tabs. Just about all have sleeves (I noticed 3 or 4 while sorting that didn't). Some may get bulk erased before they are sent out, but most will be left in whatever state they are in (if you have some amazing interest in reading market research reports on products from 10 years ago, then this is your chance) If anyone wants some, tell me how many you want, and where you want them sent. All I'm asking for is postage + $1.00. For that price, you can have as many of whatever kind you want (up to the max number I have, which I don't yet know as the pile is still growing). -chris <http://www.mythtech.net>

Help! need 400k/800k Mac os 6 or 7 diskettes!

by cb＠mythtech.net

>Do older external 400k drives work with System 8? I doubt it. I'm pretty sure Apple removed support for 400K disks at the OS level starting with 8. Although I could be wrong. > I find it hard to >swing a dead cat without hitting a pile of external Mac (or Apple II) >disk drives. Are you sure they are 400k drives? The platinum colored ones that were pleantiful and worked with the mac and the IIgs are 800k drives. If you really find an old external beige 400k drive for the Mac, I'd love to have it.

If a server is busy, it might queue mail up; mail queues are normally run at regular intervals but the size of the interval depends on the sysadmin who set it up (15 minutes is common). If there's a temporary DNS failure, mail might be queued for longer. There are various other things that might delay mail -- on a busy server, set up to use idents, mail from a PC might get delayed long enough to be deferred until the next queue run (and then deferred again, and...)

GE 73 bulbs for RL02

by dundas＠caltech.edu

Can anyone recommend a good source for the GE 73 bulbs used in the front panel switches of the RL02? A web search turned up Atlanta Light Bulbs. They claim to have them for $0.99/ea, minimum quantity 10. However when you try to check out, the minimum $ order is ~$30. I don't mind buying 10, but 30 is too many and I'm not really short on other bulbs at this time. Any suggestions? Thanks, John

[hunts through directories on nearby machine] Ah, that one's for the passive (DIN plug) one: A three-resistor divider chain, 1K0 at the top, 220R in the middle, 1K0 at the bottom, connected to ground (pin 2). Data+ (pin 1) goes to the to of the 220R, Data- (pin 4) goes to the lower end. A pair of 56R resistors goes from each of Clock+ (pin 3) and Clock- (pin 5) to the top of the upper 1K0. A 10 uF electrolytic goes from the junction of the 2 x 56R and upper 1K0, to ground. Jules Richardson has my pile of paper schematics, and I think that's where the other one is :-( Oh, but of course I have the box itself. Here we are: C1, C2: 10uF 10V C3: 10nF ceramic R1, R2: 56R R3: 100R R7: 470R D1: OA47 (anything with a low Vf, eg a Schottky diode, should do) IC3: LM7805 LED1: any old red LED (or you might want to change the colour for the combined clock/terminator unit) SK1: 5-pin 180deg PCB DIN socket SK2: power jack Fit wire links at LK1, LK2, LK3. Do you needs the component values for the collision-detect circuitry as well?

HP9k video and other questions

by kd7bcy＠teleport.com

Does anyone have a pinout for the video connector on an HP9000/425? Or a list of compatible monitors(doesn't seem to be VGA unless the whole thing is dead)? Lucky me, I went to Wacky Willy's yesterday and found an Apollo keyboiard and mouse and an HP-IL mouse! Another question that is a bit OT... Same WW visit I found a Fujitsu RA12 DSL modem. OK, it seems that it's for Verizon frame relays only, and I don't have a PS for it anyway. But trying to reverse engineer the thing I found a PS port pin labeled "PRW_GOOD". What does that mean? the rest of the unit wants +/-15v, 5v and 3.3v on various pins but it's probably going into a parts box, I'm just curious what it might be and what sort of signal it would be. -JR

Do you really _need_ oiled tape, or can you get by > without it? I odn't know how it's oiled (mist probably) but it's oily enoug that if you leave it on a stack of paper, magazine, clothing, etc it leaves a nasty stain the next morning. Haven't touched the horrid stuff in a decade or two but I bet it ozidizes faster. Unless you're punching out the assembly source to your FORTRAN compiler or something I doubt you'll wear out you punch with casual use of dry tape. You might try running a manually oiled foot or two of tape (punch RUBOUTs) once in a while to manually oil it. Just a guess. Chadless 5-level oiled tape is the most 'fun'. Instead of holes it punches little toilet-seat-shaped "U"s. Umm not so good for optical readers, but fine for mechanical readers what stick a little rob up the hole to read. I have an article about different types of readers talka about readers that blow air through the holes, detected with a little 'sail' on a microswitch, and running the chadless tape over a corner to tilt out the flaps for optical reading. Sheesh, why bother.

I don't know why everyone's so hot to buy old oxidized crumbly tape when you can buy it BRAND NEW MANUFACTURE from www.westnc.com for cheaper... mylar too (not cheap). * Mylar is shiny and strong. You can (almost) tow a car with it. * Paper is, well, paper. It rips. * Except when it's not: there are paper-mylar-paper hybrid tapes, which were once popular; it handles like paper but is much tougher. In the URL below, the larger picture on the left is hybrid tape. * There are oiled paper tapes, but those were mostly for mechanical systems. Most "modern" punches handle mylar. ASR33's and the like do NOT, they like oiled paper. Many really-low-cost readers, like from the early hobby computer era, prefer black tape, since the cheaper reader heads needed 100% contrast (and yellow tape passes yellow->IR (incandescent) light). http://wps.com/projects/paper-tape/index.html PS: A quick check of WestNC's website shows skyrocketing prices!

Retro Computing Society of RI

I'm fowarding this from Geoffrey Rochat of the RCS/RI, confirming that they do, in fact, still exist. Oh yes, the RetroComputing Society of Rhode Island is still very much in business (www.osfn.org/rcs). {As is the Rhode Island Computer Museum (www.osfn.org/ricm).} I don't know why you couldn't get through by e-mail, other than the fact that "Shrimp", the RCS/RI's faithful Sun server, has its good days and its bad days, and it's anyone's bet what today is. And I don't know whether the phone is still there or not, but unless it's a monthly Open House it's a crap shoot as to whether anyone's on-premises to pick it up. I for one don't subscribe to Classic Comp, having dropped it after having watched a particularly ferocious case of flaming break out, so this was kindly forwarded to me by Marc Bileau, who is very active in the RCS/RI's activities. So, just what is this item up for auction? I doubt we're bidding on it in any case, as money is a bit tight all around right now.

by cb＠mythtech.net

>> I may have an old SE/30 ethernet card... > > >Also, I believe that I'll need some sort of riser? The cut-out on the >case is 2 inches above where the motherboard is... No, the SE/30 Ethernet card is a two part card. One part plugs into the mobo's PDS slot, then there is a ribbon cable that connects it to the 2nd part which screws into the slot casing for external access. So no riser card as the ribbon cable spans the distance. -chris <http://www.mythtech.net>

These are labelled J1 through J6. J1,J2 are motor control. J3, J4 are read card. J5,J6 are write/control card. J1,J2 are closest to front. On the top edge of the write/control card (closest to rear) are the two fifty-pin I/O connections. The manual says nothing about JA through JD. Perhaps it is an add-on formatter, which is not detailed in the manuals. Hope that helps, but I don't see how. Nothing matches for connectors.

Update: VAXen available.

by cmcmanis＠mcmanis.com

I talked with the folks at BDI and these lots aren't going to be part of this week's auction after all (they had a lot of stuff queued up) they assure me that next week (closing on 19th of October) the lots will be available. Next week I will follow up with the exact lot numbers for those of you who were discouraged by the extremely difficult to navigate mechanics of their site. --Chuck --------------------- Previous Email ... A number of VAXen are available this week from www.auctionbdi.com. I gave them all of my "spares machines" which I cannot store and no one in the Bay Area wanted. The good news is that BDI will ship them to you pretty much anywhere in the country and the minimum bid is $25. The lot to look for has 3 MV3400's (in BA213 cases), one VAX 4000/300 (in a BA440 case) and one MicroVAX II in a pedastal BA23 case. I don't recall how complete they are, I do thing the 4000/300 is complete except for some DSSI plugs which I needed to bring my 3800 on line. Two of the 3400's have the front "door" (one says MicroVAX 3400, one says VAXServer 3400). If you've got a 3400 or 4000/300 there are plenty of parts to "enhance" your system. I believe the 4000/300 has 192MB of memory but can't swear to it) There is also a MicroVAX 3600 in a H9644 rack. This one I've never looked at in depth other than to note that it has a 4 SCSI drives and a tape but a gap where the SCSI controller had been. Given that it couldn't talk to the disks I pretty much ignored it. Finally there are some PC parts with a nice 17" NEC 5fg monitor (including the special NEC VGA cable). The monitor is nice but not an "Energy Saver" (it stays on as long as power is applied, no standby mode) Probably not of interest to this crowd but I thought I would mention it. --Chuck

Multi-CPU Qbus VAXen

While the note doesn't describe how, it does indicate you have to reconfigure the auxiliary processors. Things like disabling the TOY clock, the bus arbiter logic, setting the address of the Interprocessor Communications Register (ICR, the "mailbox" you referred to). You can however do this in regular backplanes. Okay okay, you may want to make sure you use a BA11-S since it's Q22 and all Q/CD slots. The common BA23/123 backplanes would be pretty short on Q/CD slots for more than two processors unless you don't need memory for them... And then the bus termination would get pretty funky, too.

While there are plenty of applications where UMA is handy, necessary, or essential, there are cases where it isn't. I'm sure somebody used the feature, or it never would have been put in silicon. When I thought about the 3520/3540 I wondered if they used these features with redesigned CPU boards to provide a different memory interconnect but take advantage of the ICR etc. --S.

To me the inside of a Fujitsu > M2351A Eagle is as impressive machinery as a Harley engine. Now that would be impressive! Showing the engineering, machining, and general complexity of gear like this would I think be literally awesome. You might not get the kiddies to conceded that it could be cool to play games that aren't photorealistically rendered (let alone ASCII), but I think they'd be dumbstruck by seeing how enormously complicated real world objects can be. The real-world analogy would be the moving partial cutaways of motors seen at autoshows. I'm sure it's come up before, but I don't remember seeing anything like this at the Boston Computer Museum many, many years ago. Are there some exhibits like this in the CHM's new digs? --S.

DEC 11/23 FP option (FPF11/M8188) information request

by pat＠purdueriots.com

I've managed to pick up an FPF11/M8188 (PDP-11/23 Floating Point option) for my PDP-11/23, and I'm wondering if anyone here knows how to set up/ configure this thing. It's a standard-looking dual-height QBUS module, with a 2x20 pin header at the top of the card (with the QBUS fingers pointing downward. I've got a non-+ 11/23 CPU board that I'd like to get it to work with, currently stuck in a BA23 cabinet.

And presumably you can 'get way' with more on shorter networks. Indeed. I once ran a whole classroom (about 16 Beebs, I think) using cables made up of a short length, about 6", of thin screened 4-core with a DIN inline socket on one end, the other end going to a DIN plug to which I also soldered a longer (3'-6') length of the same wire, ending in another DIN plug. A daisy-chain of those worked fine at full speed. Later Econet starter kits used Y-adaptors (3 DIN sockets in a Y shape) and low-cost DIN cables (as often used for low-end MIDI systems, cassette recorders, etc). > > Level 2 Filserver -- runs on a Beeb with a 6502 Second Processor, uses > > > Level 3 Fileserver -- runs on a Beeb with Beeb with a 6502 Second > > Processor, ADFS, and a 10MB or 30MB winchester.

The Acorn hardware certainly supports that. No, I don't remember ever trying to install one on a 20MB or any size other than 10MB or 30MB, but I don't see any reason to suppose it might not work.

DEC 11/23 FP option (FPF11/M8188) information request

I've got a non-+ 11/23 CPU board that I'd like to get > it to work with, currently stuck in a BA23 cabinet. You mean a dual-height KDF11-A ? I'm not sure if it'll work with that; it's designed to work with a quad-height KDF11-B or an 11/24. The same FPF11 works in 11/23 Qbus and 11/24 Unibus systems, and MINC systems. You ought to have a 40-way ribbon cable with a 40-way (2x20) female header on one end and a 40-pin DIL header (to fit into a normal 40-pin DIL IC socket) on the other. If it didn't come with that, you only have half the system and you should claim a 50% rebate from whoever sold it to you. Failing that, it's in a dangerously incomplete state, and you should probably send it to me for safe disposal... QBus fitting: The 40-pin DIL header goes into slot 2 on the KDF11-B -- that's the 40-pin socket next to the CPU chip, nearest the centre of the board -- with the red stripe (which marks pin 1) on the side of the cable furthest from the edge connector fingers, and the cable exiting from the plug/socket towards the centre of the PCB. Fold the cable back over the DIL plug and the CPU chip, then fold at right angles so the cable comes off towards the back of the KDF11-B board with the red stripe on the left (as you look into the backplane from the back of the machine with Slot 1 at the top). The 40-pin female header fits onto J1 of the FPF11 with the red stripe on the left, and the FPF11 fits into Slot 2 of the backplane. Ditto for a MINC. Unibus fitting: The 40-pin DIL header goes into slot 7 (may also be marked E4) on the KDF11-B -- that's the 40-pin socket nearest the Row A side of the board -- with the red stripe (which marks pin 1) on the side of the cable nearest the Row F fingers, and the cable exiting from the plug/socket towards the edge connector fingers. Fold the cable back over itself and pass it over the back of the CPU card. Then give it a half-twist so the red stripe is now nearest Row A, fit it to J1 on the FPF11 and fit the FPF11 in Rows A...D of the first slot *after* the memory cards. The order of cards on the bus should be: ------------- 11/24 CPU ----------- ------ Unibus Map (or memory) ----- --------------- memory ------------ --------------- memory ------------ --------------- memory ------------ --------------- memory ------------ ---------- FPF11 ------ (empty) terminator or jumper Jumpers: There are 12 jumpers labelled W1...W12. W6 and W9 are always fitted. W1,W2 are near the edge fingers for Row A. W3 is near the fingers for Row B. W4,W5 are near the fingers for Row C. W6 is near the back of the board between Rows C and D. W7,W8,W11,W12 are near the fingers for Row D. W9,W10 are near the back of the board opposite Row D. Jumper: W1 W2 W3 W4 W5 W6 W7 W8 W9 W10 W11 W12 Unibus: R R I R R I I I I R I I QBus: I I R I I I R R I I R R (I = inserted R = removed) -- Pete Peter Turnbull Network Manager University of York
