All: I?m trying to build this 32-bit debugger program (using MASM on MSDOS 6) and it doesn?t build anything past the first obj file.

Are you aware of the fact that the RL02 will appear as five drives to OS/8? RLnA to RLnE? Apart from that, I can't help you at the moment. My PDP8 systems are all offline, and have been for a couple of years now. Although I have a real 8/A with RL02 drives, which do work. Too long for my memory to be fresh on this one.

hey, a digest reader has an eBay feedback comment!

by classiccmp＠memory-alpha.org.uk

Hi, > On the buying side, I also have a good suggestion - so much of the >buying on eBay these days is facilitated through PayPal (50 % or >better?). As a result, eBay knows when a seller has been paid. So >why not give automatic positive feedback. I mean, what really would >a seller have to say after the buyer pays? I can tell you what a seller might have to say.... I had a case of a US buyer paying immediately for an auction he'd won, but the postage specified was for UK delivery and there was a clear instruction for international buyers to contact me prior to sending payment for postage costs. Needless to say, he refused to pay the extra few pounds for postage. But instead of emailing me to arrange to back out of the deal so I could offer it to the next bidder, he contacts eBay and PayPal and has PayPal freeze my account because I'd allegedly ripped HIM off and didn't have the item I'd auctioned! I got the last laugh though. To get PayPal to reinstate my account I had to provide them with a tracking number for the parcel....the amount I'd charged for postage just barely covered surface mail to his location, which would take 12 weeks to get there....!!!! LMAO! Outside of a couple of non-paying bidders, that was the only time I've been forced to leave negative feedback. But unfortunately, there are some real aholes out there. :-( TTFN - Pete.

It uses the same kind of leaf switches but mounted in a completely different way, and the leaves themselves don't act as electrical contacts on the CIT one, just as secondary springs to push the thin contact plates. If I remember correctly, the CIT keys look sort of like this if chopped in half down the middle: II-||-II ICLKK I ICLKK I _CLSS _ |C LS | -------- D where C is the contact plate assembly S is the main spring K is the bottom of the key plunger L is the leaf spring _ is the place where the key plastic comes into two halves I is the tab which holds the bottom half onto the top half - is the bottom of the key D is the solder tabs for the contact plate | are the walls of the bottom part of the key The leaf springs look like this if zoomed in, if I remember right: side: | | < \ \ front: _______ |_ _| | | | | |_._| / _ \ |_/ \_| I also worked out the complete key matrix for the CIT keyboard at one point, I'll see if I can find it.

Now I need some OS/8 experts...

by charlesmorris＠hughes.net

Now that OS/8 is running on my 8/A, RL02 system, I find I'm in need of some more detailed help. Although I'm wading through the 900+ pages of the "OS/8 Handbook" (and the Device Extensions document which at least addresses RL01's), I'm having a problem adding device handlers as follows. When I built the OS/8 image, it looks like I added only one RL02 partition (here is the current BUILD printout): >sim> bo rl > >.SET SYS NOINIT > >.RUN SYS BUILD > >$PR > >BAT : *BAT >KL8E: *TTY >LPSV: *LPT >RK05: *RKA0 *RKB0 *RKA1 *RKB1 RKA2 RKB2 RKA3 RKB3 >RX02: *RXA0 *RXA1 >TD8A: *DTA0 *DTA1 >R2SY: *SYS *R20A > >DSK=R2SY:R20A >$ Doing a DIR shows "118 Files in 2517 Blocks - 1515 Free Blocks", or ~4000 total blocks on the disk, which is also consistent with one RL02 partition (A=40%,B=40%,C=20%) of the total 10000 free blocks. The RKB0: Diagnostic Pack has several handlers including: RL2SY.BH (which is what I am using), and also RL20.BH, RL21.BH, and RL2E.BH (not sure what that one is). But any attempt to LOAD RKB0:RL20.BH (for example) causes SIMH to stop with a "HALT instruction, PC: 20100 (ISZ 122)" message. I tried removing R2SY: entirely (after setting SYS to RKA0:) and still it won't work when trying to install other RL handlers. Also when reloading it will only allow n=1 (platter) which I suppose is correct. This may be why I only have one partition. I did this over a year ago and don't remember all the details. ANY ideas how to install the next partitions (R20B and C)? Also, since I am planning on adding a second RL02 drive, I will need (I think) R21A, B, C to appear in the active list. Is it even possible to add a second RL02 under OS/8? The C partitions aren't really necessary and are slow. I doubt I will ever get close to filling up even the A and B's (8 Mb per pack).... Thanks for any help. -Charles

hey, a digest reader has an eBay feedback comment!

by mkath＠charter.net

I'm compelled to comment on the eBay topic. First, I have to say that while it isn't bits and bytes, it is relevant to the group. A lot of collectors of classic gear actually get that gear from eBay. Every one of my 20 or so classic systems came from eBay... Anyway, I recently bought an item and received this in a form e-mail >from the seller: 3)Am I going to receive a feedback from you since I paid immediately. Due to overwhelming feedback request(we are all feedback junkies), I set my system to Automatically leave POSITIVE feedback to buyer when the following TWO conditions are met: i) item is paid. AND ii) Buyer left me a positive feedback. Of course, I was steamed about this. It's just not in the spirit of how eBay is supposed to work. I actually went to eBay to try to find a policy about this, stumbled into the discussion forums and quickly realized that eBay, like Chuck said, has all the integrity of "open-air bazaar in Marrakesh". Tony's suggestion of keeping feedback private until both parties submit feedback seems like a workable idea. On the buying side, I also have a good suggestion - so much of the buying on eBay these days is facilitated through PayPal (50 % or better?). As a result, eBay knows when a seller has been paid. So why not give automatic positive feedback. I mean, what really would a seller have to say after the buyer pays? It's amazing that in their recent revamp of the feedback system, what they delivered is the best they could do. -Matt

new ebay feedback

They now let you grade description, email responsiveness of seller, etc. Hopefully this will improve the feedback score to a more meaningful metric, but it will probably take a while to accumulate.

VTserver : update

by charlesmorris＠hughes.net

I have found, by scoping the data lines in and out of the laptop, that the endless loop on the laptop is only an internal display glitch - i.e. even though when I type characters they echo endlessly on the screen until another key is pressed, only the one (correct) character is sent to the PDP-11 at each keypress. Similarly, when ODT sends a single "@", continuous "@@@@@@@..." echoes on the display. Who knows why. It's annoying but apparently does not affect the functioning of VTserver. Then there was some more learning to interpret the cryptic messages for input and output devices. Although I thought the program was supposed to send my OS/8 image automatically from the "virtual tape" (and its name is in the .vtrc file with 0 = copy bootstrap, 1 = image file), I eventually learned that entering "vt(1,0,0)" (or maybe it was "0,0,1") would accept the OS/8 image file for input. Not sure if my output device command is correct though. I'm trying to write to my second RL02 drive (RL1: on the PDP-11/23+ with a "1" key) and the only output device string that would work is rl(0,1,0). The program does not explain the significance of the (n,n,n) fields, although it does prompt for a string in that format. It did display a confirmation each 100Kb, and did write the entire 2.5 Mb file to the RL drive! Although it's anyone's guess as to whether I did this correctly. When I put the pack in the RL02 attached to my 8/A and press Load, the "Ready" light does not come on, which I believe means the heads have not locked on the servo track. Which is strange because even if I wrote to the wrong places on the disk, it still should be able to sync up. AFAIK it is not possible to overwrite the servo tracks by writing blocks to the disk through a controller card? Or maybe the light is burnt out... or the pack I used is bad... Please also explain to me the limitation for the size of each partition under OS/8 again? 2500 Kb is less than 2 Mw at 12 bits per word? thanks -Charles On Thu, 24 May 2007 08:15:14 -0700, you wrote: >On 5/24/07, Charles <charlesmorris at hughes.net> wrote: >> yep, Win XP Pro. >> I don't want to go backwards to 98 though :) >> Anything else you could recommend? >> >> -Charles >> > >I wouldn't want to install Windows 98 on a system I was currently >using either.

O YEAH! What a deal!!!

by jba＠sdf.lonestar.org

While $89.93 is quite an oddball price, I wouldn't say its outrageous. This graphics card is for sale in an eBay store, not on an auction, so it will just site there until someone buys it. Its conceivable that there is a Rainbow or two left somewhere in some forgotten industrial application where replacement is not an option without some extreme costs related to it. I've seen Rainbow parts on sale for much higher, mostly from DEC resellers. I still use a Rainbow, and there was a time when my stock of parts was much lower that I may have considered purchasing this card at this price. You have to remember that there is some cost to maintaining a stock of obscure parts that probably only a handful of people in the world would even ever consider purchasing. If he sells it for that price, though, then I think i'll consider getting into the used Rainbow parts business ;-).

CiTOH terminals (was Re: Well, now I've gone and done it... Dragged home more big(ish) iron...)

There was a 101 there, and cheap too, but > it had no keyboard. I may haev a few CiTOH terminals to drag to VCFmw if there's any interest. Closer to the event, I'll inventory what I have and see if I kept any spare keyboards "just in case", if anyone out there already has a terminal, but can't figure out why their VT100 keyboard doesn't work with it. I remember back in the day, since we had dozens of CiTOH and DEC terminals, looking over the available schematics for both and not being able to figure out how the keyboard works. I think it was a matter of inadequate/fuzzy docs more than anything else. Does anyone know of a good printset to pore over to see the nuts-and-bolts of a VT100-era keyboard? ISTR the crux of it was a 6402-type UART squeezing out the keystrokes at some slow baud rate, but I can't recall any essential details right now. I'm just curious if it's possible to swap a crystal or make a simple, switched change to allow one keyboard to work across both vendor's product lines. We used to have lots of dead keyboard when there was one or two terminals on everyone's desk. Since the company was shrinking at that stage, we never bothered fixing them - we just pulled one off a vacant desk and kept working. The number of working keyboards never shrank below the steadily decreasing size of the staff, so economically, it made sense. I think I only saved working keyboards in that set of 4 van loads, but it's entirely possible I picked up one or two dead ones. Right now, I have to search the pile for a VT100 keyboard to get my DECmate I back up and running so I can press it into service as an RX01/RX02 image archiver and finally whittle down my cartons of floppies. -ethan

Microvax II

by chrism3667＠yahoo.com

um, I've had this thing for a while now. It's pretty shabby. The front plastic bezel thing fell off (prolly cause SOMEONE keeps pushing the Honda against it). Other parts and pieces are strewn around the yard. I resisted the urge to send all that crap out for the metal pickup (oh anyone want a rusty 1914 Dalton lathe - only $75 if you pick it up. Real nice babbitt spindle bearings ;). So what to do? Should I actually turn it on? Some board fell out of it not long after I pulled in the driveway 2 winters ago. What's it good for anyway? I hate to just chuck it. At one time these things were going for a G+ on duh bay. Not this puppy though. I'm totally open to suggestions. If anyone has a clean doner (or parts) I could very well be interested. I can't say I have much in the way for a trade though... ____________________________________________________________________________________You snooze, you lose.

govliq: Would anyone near Norfolk "relay" Rolms to me?

by erik＠baigar.de

Hi there! In Norfolk there are quite often Rolms 1666B for auction, which can readily be exported to Germany since they do not require demil. Is there any vintage compunter freak out there who would pick up such a lot and send them to me? A commercial carrier charges wants $750 to $1200 for this task. I am not willing to pay that much money since this is only a hobby for me. Maybe one of you is there by occasion??? Does anyone know a cheaper way for shipping of govliq lots? Best regards, Erik.

MicroVAX I console port pinout

by hoelscher-kirchbrak＠freenet.de

Hi, I'm currently building a MicroVAX I (slowest VAX ever) from parts. I've already got the BA23 box, CPU (2 boards), memory, disk and ethernet controllers. But unfortunately the MicroVAX I console patch panel is missing. Has anyone got a spare one to give away or swap? Or does anyone know the pinout for the console port on the M7135 MicroVAX I DAP module? There are two connectors which look like this: |-----------| | o o o o o | | o o o o | |-----------| The connectors are identical to e.g. those on a DLV11-J serial interface. I guess one is for the console connection and the other one for the baud rate selection. Another interesting question is: What are the two switch blocks on the M7135 DAP module good for? Anyone who knows about that? Any help is very much appreciated! Regards Ulli

PDP-11/84, PMI and Q-bus

by RodSmallwood＠mail.ediconsulting.co.uk

So in order of preference: KDJ11-BF (M8190-AE) Goes in slot 1 KDJ11-Bx MSV11-JD Slot 2 MSV11-JD Slot 3 Right so that's the answer. Good I shall now look for those.

Practically speaking, if you can't get a KDJ11-E M8981 PDP-11/94 or /93 board, the next best is a KDJ11-BF M8190-AE which is the 18MHz board with floating point accelerator used in an 11/84 or 11/83. But any KDJ11-B would do, the permutations being 18MHz or 15MHz, and with or without FPA. The plain M8190 (no suffix) KDJ11-BC can't have an FPA added. The other common flavour of KDJ11 is the MM7554 used in the 11/53 but that can't use PMI (which you need). All the above are quad-height boards. You do not want the dual-height KDJ11-A. > " Put a memory card type MSV11-xx (M????-??) in slot2." MSV11-J, M8637, or failing that, MSV11-RA, M7458. Look in http://www.dunnington.u-net.com/public/PDP-11/QBus_memory to see how much memory the various versions have. One or two MSV11-JD would be best. > " Put another (optional) memory card type MSV11-xx (M????-??) > in slot3." See above. And that is the correct order. If you only get one memory board you may also need a Minimum Load Module for slot 3. -- Pete Peter Turnbull Network Manager University of York

Need help with VTserver

Anyone? I'm having a problem since I think VTserver was originally intended to work with hardware flow control (handshaking) and 11's console port is a simple three-line with no flow control. This is the version I'm using, that runs on Windows machines: http://home.alltel.net/engdahl/vtserver.zip Max SLU speed on the -11 is 19200 so that's what I'm running. I tied pins 1,4,6 together on the DE-9 connector to COM1: (to "fake" a handshake). After starting ODT on the 11/23+, and "VTserver 19200" in the laptop's cmd window, I see more or less continuous strings of "@" until I hit ^B and then ^A to download the bootstrap. The "copy" file then downloads successfully, but when prompted for the input device (RL), when I hit the R key, it echoes continuously at high speed (RRRRRRRRRRRRRR....) until I press the L, then LLLLLLLLLLLL... etc. and when hitting return, of course it's a "bad device" message. Is there anything I can do about this? Is it possible to use XON/XOFF flow control (I don't think the "copy" program does, though?) What did I do wrong? thanks Charles

I have not used it in a couple years, but it is my recollection that when you start the VTServer executable, and assuming that your INI file is set up properly, it opens the COM port, which is connected via (I think) a null modem cable to the console serial line on the PDP-11. It then copies an ULTRIX OS to the PDP-11 and boots Ultrix. It seems like it took a few minutes to copy the Ultrix shell to the PDP-11. Once Ultrix is up and running, you can copy files to and from the PDP-11 disk packs. I have pulled images of many packs to my PC this way, and I have also copied disk images from my PC to an actual PDP-11 RL01, RL02, and RK05. It always worked fine for me except when a pack had bad blocks. I think that my version of VTServer is more current than the one that Johnathan Engdahl has on his site. When I was working with VTServer, I encountered some bugs. Fred Van Kempen fixed these for me and sent me an updated VTServer system. It sounds like you could use a PDP-11 to create RL01 or RL02 packs for use on the PDP-8. However, as someone mentioned in an earlier post, you could not do the same with RK05 packs because the sectoring is different. I think the metal hub that is mounted on the platter is different as well and has a different number of grooves in the hub. If you want my version of VTServer, let me know. I may stick in out on my web site so it can be downloaded. Ashley http://www.woffordwitch.com

PDP-11/84, PMI and Q-bus

by RodSmallwood＠mail.ediconsulting.co.uk

Hi Jerome, Sorry I did not pose the question very well. I am trying to get back to the original issue. Which is: 1. I have an 11/94 with a missing cpu board. 2. The correct CPU board as you know is too expensive. 3. Please will somebody give me a low cost alterative in a form I can understad. 4. So all I want is for somebody to say is something like: " Put CPU board type KDJ11-xx (M????-??) in slot 1." " Put a memory card type MSV11-xx (M????-??) in slot2." " Put another (optional) memory card type MSV11-xx (M????-??) in slot3." or what ever order is correct and will run in a PDP-11/94. (xx = please supply correct suffix) (M????-??) please supply correct module number) 5. So far I know a lot about what won't work but not a lot about what will!!

FOG DOS discs

by aek＠bitsavers.org

> > these? > > - http://www.znode51.de/fog/filelist.htm nope. Those are the CP/M and Language discs FOG started supporting DOS later. The master discs that were donated to the Computer History Museum start around 1986 and go to 1990 (vol 408). There were also specialty collections for various CP/M boxes, but unfortunately they are water/mold damaged are are unreadable (the discs are glued to the inner sleeve). I'm grinding through FOG_DOS today, and will put them up under http://bitsavers.org/bits/Users_Groups/FOG later today when I've finished reading them.

Need help with VTserver

by charlesmorris＠hughes.net

Thanks to a creative suggestion from Ethan, I want to use VTserver to transfer a bootable OS/8 RL02 image from my laptop (which works fine under SIMH PDP-8) to an RL02 pack on my 11/23+. Then I will remove that disk from the drive on the -11, place it in the 8/A's RL02 drive, and voila - it should boot OS/8! (The disks are identical format regardless of system, only the programs themselves differ). Meanwhile I am confused about VTserver's use and terminology of serial ports. I got a PC-executable version here: http://home.alltel.net/engdahl/vtserver.zip and modified the .vtrc file (as recommended in the embedded comments) to send only two tape records, "copy" and the RL02 image. I realize a null modem cable will need to be made. So far so good? But I don't understand the difference between, say, "ttyd1" and "ttyp9"... those are Unix terms, not DOS... will one of these be correct to enable the serial port connector on the back (one of the COM ports)? If not, how do I patch this? I was a hardware designer and 8/16 bit assembly language writer (and that was over 20 years ago) and definitely never a C, Unix or Windows programmer, so please bear with me. Any helpful hints appreciated :) -Charles

Pat, what you have is what I would describe as an 11/93 with an Qniverter. That will not be exactly the same thing as an 11/94. The KTJ11-B, which is DECs Unibus adapter, have some special signals to the CPU telling it that the KTJ11 is there, and that changes the behaviour of the Qbus, according to the manuals. I haven't said that the wiring of the memory slots in an 11/84 (or 11/94) isn't the same as in a Q/CD backplane. It must (by default) be atleast very similar to a Q/CD backplane. However, there are some special signals, and also some signals that change behaviour in an 11/84 and 11/94, according to the manuals. And that will only happen if you have a KTJ11-B in there.

PDP-11/84, PMI and Q-bus

"Rod Smallwood" <RodSmallwood at mail.ediconsulting.co.uk> skrev: > Hi > > Well that's seems to define the 11/84. > How does this all apply to the 11/94 > (which is the real problem) Well, the UBA is the same, so the same PMI Unibus signals are originated at that end. No memory can exist in an 11/94 though, since all the memory are on board. However, the communication between the CPU and UBA is using the PMI protocol, still. However, the dealings with interrupts and so on must still be done in the same way as for the 11/84 as well. So I would say that the 11/94 behaves exactly like the 11/84. (Do anyone know if an 11/94 with 2 megs on board could use an external 2 megs?)

Hi Well that's seems to define the 11/84. How does this all apply to the 11/94 (which is the real problem) Rod -----Original Message----- From: cctech-bounces at classiccmp.org [mailto:cctech-bounces at classiccmp.org] On Behalf Of Johnny Billquist Sent: 21 May 2007 21:41 To: On-Topic and Off-Topic Posts; Pete Turnbull Subject: PDP-11/84, PMI and Q-bus Okay, since this topic have become a subject of much discussion and some diverse opinions, I decided to really read the manuals to try to find the bottom of this all. My main source of information here have been the "KDJ11-B CPU Module Users's Guide". EK-KDJ1B-UG-001 Now, to start with the position of the CPU card in an 11/84. Chapter 7, section 7.2. Page 7-1: "7.2 PMI INTERFACE The PMI interface signals are defined as the PMI bus master signals, the PMI slave signals and the PMI Unibus adapter signals. These interface signals are assigned to the C and D rows of the backplane and are defined as the interconnect bus. The PMI interface signals on the C/D bus are normally assigned two pins to provide an interconnection between the slots. The KDJ11-B module is only assigned one pin and therefore its position in the backplane is critical. The LSI bus signals that are used with the PMI protocol use the A and B rows of the backplane defined as the LSI bus." Now, if Pete is correct in that the PMI bus on the 11/84 really goes to both pins on all slots, then it should be okay to place the CPU in any slot. I haven't tried that, but I might when I have the time. I suspect he's right since otherwise I would have expected the CPU to be in slot 3. But DEC could be doing some fancy wiring... :-) The fact that the placement is critical is obvious if we talk about Q-bus systems, and I suspect the comment is written from that point of view. As for wether Q-bus memory (or any other Q-bus peripherial) will work, I'll quote some signal descriptions. Chapter 7, page 7-4. Table 7-3 PMI Unibus Adapter Signals "Pin: CF1 Mnemonic: PUBSYS L PMI Unibus System In a Unibus system, PUBSYS L is asserted by the UBA to direct the KDJ11-B to follow PMI protocol for all data transfers, wether the PSSEL L is asserted or not. LSI-11 bus protocol is disabled for all PMI devices when PUBSYS L is asserted. In an LSI-11 system, PUBSYS L is always negated. If PSSEL L is negated, the KDJ11-B follows LSI-11 protocol and the PMI memory then responds to the LSI-11 protocol by the LSI DMA devices." Chapter 7, page 7-5. Table 7-4 LSI Bus Signals "Pin: AF2 Mnemonic: BRPLY L Reply During PMI cycles, BRPLY L is asserted by the KDJ11-B and the PMI slave to prevent the next bus master from gaining control of the bus too soon. In a Unibus system, BRPLY L is asserted by the UBA as a slave response during the PMI DATOB cycle and interrupt DATI cycle. *** NOTE *** The PMI memory slave modules in a Unibus system must have BRPLY L disabled at all times. Pin: AH2 Mnemonic: BDIN L Data Input The BDIN L signal is only used in PMI Unibus systems during interrupt grant cycles. The KDJ11-B asserts BDIN L after it gates the interrupt priority, BDAL bits <3:0>, onto the bus. The UBA then latches the interrupt priority data using the leading edge of BDIN L. Pin: AM2 Mnemonic: BIAKI L Interrupt Acknowledge In Pin: AN2 Mnemonic: BIAKO L Interrupt Acknowledge Out These signals are only used in PMI Unibus systems during the interrupt grant cycles. The KDJ11-B asserts the BIAKI L signal, and the UBDA acknowledges it by asserting one of the Unibus bus grant signals. Pin: BB1 Mnemonic: BPOK H Power OK This signal is only used in PMI Unibus systems for the Unibus power-up/power-down protocol. This signal is asserted and negated by the UBA in response to the Unibus AC LO signal. The assertion of AC LO may be prolonged by the Unibus devices or the PMI memory during power-up." I could go on describing more details on how these signals are used, since it's all described in the manual. Suffice to day that the KDJ11-B *knows* when it's in a Unibus system (i.e 11/84) and will not behave like a normal Qbus. First of all, it will always use PMI protocol to access memory, no matter what the memory might claim. Second, interrupt handling is done differently, since all interrupts are expected to be dealt with via the UBA. There are also schematics for different signals in the manual, and you can clearly find the PUBSYS L signal included in some decoder path as a way to force a specific behaviour independent of other signals that might exist. Now, can we now accept that it's not a Q-bus in the 11/84? :-) Johnny -- Johnny Billquist || "I'm on a bus || on a psychedelic trip email: bqt at softjar.se || Reading murder books pdp is alive! || tryin' to stay hip" - B.

Original PC Needs Rescue

by yakowenk＠yahoo.com

Hey, all, I've got mail from somebody with an original IBM PC from the first batch to be sold by IBM to its own employees. Apparently they selected employees >from a list by lottery to determine what order to deliver them, this was in the middle of the list, delivered in October 1982. (Isn't that a little late for first batch? Was the production rate not up to demand at first?) Anyway, there are several pieces: system unit, keyboard, monitor, etc.; mostly (or all?) in original cartons with docs & software & such, some still in shrink wrap. There is also some amount of PS/1 stuff, available together with the PC stuff or separately, depending on who wants what, the order in which responses arrive, and the phase of the moon. This stuff is all in Colorado, but the owner is willing to pay shipping (presumably assuming domestic!) so the location doesn't much matter. I'll collect responses and forward them in a batch, and the owner will decide who to contact and so on.

In a Unibus system, BRPLY L is asserted by the UBA as a slave response during the PMI DATOB cycle and interrupt DATI cycle. *** NOTE *** The PMI memory slave modules in a Unibus system must have BRPLY L disabled at all times. Pin: AH2 Mnemonic: BDIN L Data Input The BDIN L signal is only used in PMI Unibus systems during interrupt grant cycles. The KDJ11-B asserts BDIN L after it gates the interrupt priority, BDAL bits <3:0>, onto the bus. The UBA then latches the interrupt priority data using the leading edge of BDIN L. Pin: AM2 Mnemonic: BIAKI L Interrupt Acknowledge In Pin: AN2 Mnemonic: BIAKO L Interrupt Acknowledge Out These signals are only used in PMI Unibus systems during the interrupt grant cycles. The KDJ11-B asserts the BIAKI L signal, and the UBDA acknowledges it by asserting one of the Unibus bus grant signals. Pin: BB1 Mnemonic: BPOK H Power OK This signal is only used in PMI Unibus systems for the Unibus power-up/power-down protocol. This signal is asserted and negated by the UBA in response to the Unibus AC LO signal. The assertion of AC LO may be prolonged by the Unibus devices or the PMI memory during power-up." I could go on describing more details on how these signals are used, since it's all described in the manual. Suffice to day that the KDJ11-B *knows* when it's in a Unibus system (i.e 11/84) and will not behave like a normal Qbus. First of all, it will always use PMI protocol to access memory, no matter what the memory might claim. Second, interrupt handling is done differently, since all interrupts are expected to be dealt with via the UBA. There are also schematics for different signals in the manual, and you can clearly find the PUBSYS L signal included in some decoder path as a way to force a specific behaviour independent of other signals that might exist. Now, can we now accept that it's not a Q-bus in the 11/84? :-) Johnny -- Johnny Billquist || "I'm on a bus || on a psychedelic trip email: bqt at softjar.se || Reading murder books pdp is alive! || tryin' to stay hip" - B.

CiTOH terminals (was Re: Well, now I've gone and done it... Dragged home more big(ish) iron...)

by RodSmallwood＠mail.ediconsulting.co.uk

Hi I have just remembered how the later version keyboards worked. It was still a counter sytem but the values where fully decoded. It worked on a matrix system. Each key on the keyboard sat across the junction of one of the matrix points. The columns, say 16. Would be the output of a 4 in 16 out decoder and the rows were the inputs of a say 16 in four out encoder. Stopping the clock by pressing a key gave you an 8 bit keycode. Serialize in the usual way. Finally dedicated chips appeared. But same old matrix system.

Well, now I've gone and done it... Dragged home more big(ish) iron...

by ian_primus＠yahoo.com

Eh... another in a series of things _not_ to put into a Chevy Venture, this time featuring... A Vax 11/750 and a Vax 6210. Fortunately, this isn't going to be as bad to remove >from the van as those CDC drives were. I just need to talk some friends into helping me. But, I do want to try and get this 750 running soon. The TU58 has a bad roller (suprise, suprise) so I'll have to get some of that tubing I saw mentioned in the archives. But, I have no cartridges, so it does me little good to fix it... Any source of boot images for this critter so I can boot it with a tu58 simulator on a PC? Also, what do I really need in order to boot and install an OS, say, NetBSD? At the moment, I have no disks (anyone have a Unibus SMD controller?), or for that matter, a working, compatible tape drive (no pertec controller...). I assume that the machine needs to boot initally from TU58 every time, and then after that, it can bootstrap from disk or tape. I found the 11/750 FAQ, but it doesn't have a section for "I dragged home a big heavy Vax, now what?". Thanks! -Ian

CiTOH terminals (was Re: Well, now I've gone and done it... Dragged home more big(ish) iron...)

by RodSmallwood＠mail.ediconsulting.co.uk

I don't know if it helps but I did work on terminals in the early 1970's. Before my days at DEC I did work on keyboards. The usual design was a counter going up to 127 or 255. Pressing a key pulled down the data lines for the number representing the value of the key. This was compared with the output of the counter and when they where the same the counter stopped. Thus at this point the counter held the value of the key. Some counters could be shifted (clocked) out serially or you transferred the value to a shift register and serialized the code that way. UARTS could be used like a shift register. (Parallel in serial out.)

DEC remote power controller cable?

by charlesmorris＠hughes.net

Via the Dayton Hamvention and Dan C., I now have a nice "new" corporate cabinet for my 11/23+ and two RL02's, installed and working. It came with an 874-D Remote Power Controller which I would like to use as intended (i.e. turn everything on by flipping the BA-11SA front panel power switch). That switch connects directly to a 3-pin male Molex connector on the rear of the BA chassis. The 874-D has several 3-pin female Molex connectors labeled "DEC Power Bus". Am I correct in assuming that I just need a 3-wire extension cable between the BA chassis and one of those Power Bus connectors? If so, is there a DEC part I should be looking for? If not, any ideas which mating connectors to order (it's not critical that I use factory original pieces)? The two connectors are not identical families (the BA-11SA's connector is flat on one side and rounded on the other; on the 874-D they are rectangular). Thanks for any help. -Charles

Any Palm developers on the list?

by ethan.dicks＠gmail.com

Hi, I have been dusting off some old Palm Pilots (III and V, mostly) and am running into "decayed link" syndrome on most of my searches. I'm finding fragmentary web pages and links to abandoned projects from 7-8 years ago, and only a few things that encompass what I'm working with. I joined the Palm Developers Network, but they don't make older SDK files available for download. I'm really looking for the kit they used to have available that allows one to develop PalmOS 3.3-era stuff - so around 1999 or so, I think. Does anyone on the list have something that sounds like that? If so, please reply to me directly rather than clutter the list with stuff about Palms. To tie this search into recent events, I did see a few, very few, Palms at Dayton. The best price I ran across was a Palm V w/cradle and wall wart for $10 (and another for $15 with box). Unfortunately, that's more than they go for elsewhere. I got home and ran across a Palm Vx at the nearby thrift for $6.99 w/cradle and wall wart (along with a Garmin 12 GPS for $1.91!) Since the DragonBall is essentially a dressed up MC68000, I've always appreciated the PalmPilot innards, but I've never had a need to build my own apps. These days, everyone wants to support the Tungstens and Treos, etc., and have left monochrome Palms in the dust. Thanks for any assistance in locating ancient development tools. -ethan

Price vs value for DLT tapes

by ethan.dicks＠gmail.com

All, I have the chance to get an inexpensive "HP DLT40" drive or two... >from my googling, it seems that these drives can read/write DLT III (10GB), DLT IIIxt (15GB) or DLT IV (20GB) tapes. Are DLT IV tapes (20GB uncompressed) worth the effort of tracking down and shipping? We pitched out several hundred new-in-box DLT IV tapes from South Pole over six months ago, partially because we hadn't unwrapped one in over 4 years (we had moved up to SDLT @ 110GB each, some time prior to 1 Jan 2003). Old though they are, I'd consider an inexpensive SDLT drive and a stack of tapes to be a somewhat useful density to use for backup on any system I have lying around. What's not as clear, though, is if tapes that hold less than 20% of that are worth more than the cost of shipping. At the moment, I can get a couple of drives for essentially free (under $5, and, no, not at Dayton). What concerns me is the expense of the tapes, and more from a shipping standpoint than an actual per-tape cost. If we were throwing out these tapes last year, I can't imagine that I can't find someone else doing the same this year - it's just a matter of how much it costs to receive them. Given the things I'd like to back up (laptop, main Solaris file server), I'd want to be able to rotate tapes in a sensible scheme so as not to write to the tapes too often, but I have enough stuff to cover that one 20GB tape per month just isn't enough; I'd need several tapes per month at that density. Over the course of a year, I'd probably need tens of tapes, but perhaps with a higher density (SDLT, say), I could get away with a dozen or so tapes per year, but the drive and tapes wouldn't be as close to free as DLT IV (I've seen eBay prices on SDLT drives in the $20-$50 range). We stopped using SDLT at Pole last year (2006 data was written to SDLT and Ultrium tapes), so, again, I can see that the modern world isn't going to be as interested in them as some of the newer, multi-hundred-GB-per-tape schemes. I guess another way to phrase this might be, does anyone on the list know of a source of extremely inexpensive piles of DLT IV or SDLT tapes - either density media quickly adds up to more than the present cost of drives, so in the end, it's the weight of the tapes that's the limiting factor. Thanks, -ethan

The real differences are bug fixes. Essentially the RQDX2 is a bugfixed RQDX1 with later firmware that is aware of a larger (at that time) assortment of drives. In the real world of MSPC controllers RQDX3 is most desireable and RQDX1 the least. FYI: some flavors of RQDX1/2 didn't pass interrupt grant and MUST be the last card in the chain. Allison

Friden Flexowriter

by sethm＠loomcom.com

Well, this is either the stupidest thing I've ever done, or a really cool find that will fill me with joy. I just won a Friden Flexowriter on eBay (Item #180115571829). I've been looking for one of these for almost ten years, and up popped this one, with no bids but mine. It's almost local, so I'll be picking it up in person to avoid shipping. It'll cost more in gasoline, but it should protect against the danger of shipping damage. I'd love to hear from anyone else who has one, or who has worked on one. I've downloaded the MIT memos regarding the operation of the PDP-1 and TX-0 Flexowriters from Bitsavers, but that's literally all the documentation I have. I'm not even sure what character set this one has -- it is lacking the upper-case symbols on the number keys, for instance, and the "1" key seems to be on the right ("2, 3, 4, 5, 6, 7, 8, 9, 0, 1"). I understand they were frequently customized with their own character codes, as well. The Flexowriter in question is "not working", although it looks like it's in excellent shape physically. I've become quite handy with typewriter mechanisms recently (don't ask), so I'm hoping that whatever the problem is is fixable without terrible difficulty. If not, I'm close to Los Altos Typewriter, who (I believe? I'm not sure on this) repaired the Soroban console for the Computer History Museum's PDP-1. Wish me luck with this potential white elephant. -Seth

It loads from the system. If there is a ROM it would most likely have such a name. Do remember that the 8086 was a full 16 bit bus.

MGE EPS 2000 UPS available

by ingrammp＠earthlink.net

Ok, it's not a computer, but it's certainly computer related... i have an MGE systems 50KVA UPS available that we just removed from service yesterday. Unit has been running for 10 years ( we moved up to a newer unit ) under maintenance from MGE. This is a 480VAC 3phase input, charging a string of 40 batteries at about 512 volts, and providing an output of 220 3phase through a step down transformer. It's a big heavy thing, approx 1700 lbs for the UPS and same for the battery box, in a stage of partial disassembly now ( to get it out of the room it was in ). Best part is it's free... just come by and pick up ( liftgate truck is required... its heavy and we don't have a loading dock ) We're located in Tucson AZ. It should be a matter of nuts and bolts and having a good electrician to reassemble this fellow if you wanted to bring the whole thing up or.. if you have one of these, it's a great source of spare parts ( since they aren't made any longer ) Mike

help identifying unknown ISA card

by bear＠typewritten.org

Howdy, guys. I've got an 8-bit ISA card here that I pulled out of an IBM PC/AT 5170 machine (which apparently was a VM/PC development machine at one point, and contains program code for the PC3277/GA). I wondered if anybody could help me identify what it might be. Parts have date codes in 1985; chips of note are 32k in 70ns 4Kx4 SRAM; intel 8086, 8259, and 8254; and a pair of 12-bit monolithic DACs. I/O is by one DE9m and one DB25m.

Easy. By listening to me. :-) I have an 11/94 box, with an 11/84 CPU and PMI memory in it here, and running. It's the same backplanes, and the same Unibus map.

Correct. So if people could stop assuming that an 11/84 have a q-bus, we would get a long way towards clearing this up. If people don't know about the 11/84 or 11/94, don't write answers based on your knowledge of the q-bus based KDJ11 setups. > Figure 8-6 in EK-PDP94-MG-001_Sep90.pdf shows a PDP-11/84-A backplane > with the MDM M7677 in the MDM slot, the KDJ11-BF M8190 in slot 1, a > MSV11-JB/JC M8637-BA/CA in slot 2, and a MLM load module M7556 in slot > 3.

In fact the -JD and -JE don't even claim to be PMI memory, but just plain Q-bus memory (according to the field guide). That's definitely not useful.

Now that makes a lot more sense. So PMI memory choice is: (2 Max) MSV11-JD M8637-D 1 MB ECC PDP-11/84 or PDP-11/83 MSV11-JE M8637-E 2 MB ECC PDP-11/84 or PDP-11/83 The CPU choice is: Module Type Speed RAM ROM LTC SLU ------ ---- ----- --- --- --- --- M8190 KDJ11-B M8190-AD KDJ11-BA 18 M8190-AB KDJ11-BB 15 0 Y Yes 2 M8190-AC KDJ11-BD M8190-AZ KDJ11-BF 18 0 Y Yes 2 So..... 1. Plug in one or two memory cards. 2. Plug in a CPU card 3. Insert Bus Grant cards (Which end of the slot?) 4. Insert in Slot nine a M9302 UNIBUS TERMINATOR and a M9713 MIN. LOAD MODULE 5. Now we would have: Slot 1 M8190-Ax KDJ11-Bx 11/83 - 11/84 CPU Card Slot 2 M8637-X MSV11-Jx PMI Memory Slot 3 M8637-X MSV11-Jx PMI Memory Slot 4 M8191 KTJ11-B Unibus controller Slot 5 M7547 TUK50-BB Tape controller (Bus grant as well?) Slot 7 G7273 NPG and BUS Grant / Double Grant Slot 8 G7273 NPG and BUS Grant / Double Grant Slot 9 M9302 UNIBUS TERMINATOR Slot 9 M9713 MIN. LOAD MODULE 6. Connect up a terminal (I have several 420's) to the SLU connector. 7. Connect a TK50 drive (Which I have) to its controller. 8. Check for correct boot proms on the CPU card. 9. Switch on. Wait for smoke to clear. Look for output on the terminal. 10. Insert a bootable tape. (Which I don't have yet) All those in favor of this config say Aye!

Sorry, but your options are very few. The first three slots of that backplane are not Q-bus, but a special adaptation of it for the PMI memory and nothing else. You cannot use Q-bus memory on it, and no other Q-bus options either (atleast according to the manuals, I haven't tried in real life. I could check out if any signals differ, if it were real important). Second, the Unibus adapter required some special signals from the CPU-board as well. Your options are basically the 11/8x and 11/9x CPU boards. No others will originate the signals for the Unibus adapter required. Memory wise only PMI memory boards will do. For an 11/94, all memory are on the CPU board, so for those, the two PMI slots should always be empty. To make the power supply happy, you normally have some bus loads on them. If you go for the 11/84 instead, you also need to find PMI memory boards. That's the CPU/memory part of your system. You then need to configure the Unibus correctly, which means you need unibus grant cards in theright place of all empty slots. You probably also want some disk controller in that system.

Re Last of the Line - The answer

by RodSmallwood＠mail.ediconsulting.co.uk

Thanks to Johnny Billquist our intrepid Swedish pdp-11 collector we now have an answer to the 11/94 problem. The answer is any M8190 CPU and any M8637 memory. CPU in Slot 1 Memory in Slot 2 and 3. So CPU's M8190 KDJ11-B M8190-AD KDJ11-BA M8190-AB KDJ11-BB M8190-AC KDJ11-BD M8190-AZ KDJ11 Memory MSV11-JD M8637-D 1 MB ECC PDP-11/84 or PDP-11/83 MSV11-JE M8637-E 2 MB ECC PDP-11/84 or PDP-11/83 Before I go to the dealers does anybody have any of these?

Hi The Elliott core stores I worked on must have been the next generation. The electronics were in the two spaces either side of the core box. The boards were about a half to three quarters the size of those shown. The power supply was in the bottom of the cabinet and physically the same size as the store module. There was no monitor panel. The cabinet was full when there were four store modules and the psu present. I think the cabinets I knew were wider than those shown.

A little help w/shipping from the UK, please?

by ceby2＠csc.com

Richard, I've dealt with containerized shipping if that's a help. You can ping me off list and I can give you some pointers. But the level of effort is probably absurd for what you're attempting to achieve. Basically you just want to get quotes from ANC Express (now owned by FedEx) and ParcelPost, from the UK websites. They both do a roaring domestic surface trade, and have international shipping capabilities of course. Given the exchange rate, I hope you got a good deal, because the shipping is likely to seem expensive because we've gone from $1.70=?1 over the last two years to $2=?1. Best of luck anyway.

I want to purchase this item from ebay 130113266639 and the seller quoted me this for shipping: "The total weight is 45kg! The cheapest freight I have found costs approx #200.00 (approx $400) with UPS. It would need to be shipped in 2 boxes. If you can find a cheaper shipping quote from London, UK, N10 3AB then you are welcome to arrange your own pickup by a delivery company from here if you win the auction." Any suggestions on a more cost effective way to ship this? I suspect the person got an air shipping quote and not something slower but less expensive.

Try an actual shipping company, the kind that load big wooden pallettes onto ships.

Only drawback, you often have to pick up from their docks yourself or you'll be charged a disproportionate delivery fee for the last 10 miles, with the driver expecting a serious tip for carrying the goods in.

Not sure whether a 10-year-old quad Xeon is OT here or not - it's very late by the standards of many machines here, but I found it to have some "interestingness" value. Anyway this machine died on me recently and I don't have the heart to figure out what's wrong with it & get it going again. I offer it here first in case anyone local could use it (or the spares it constitutes), otherwise it'll go on the local freecycle. Stroller.

Not entirely sure. I got that from the field guide. If you look at the M8190 there, you'll see that the KDJ11-B is only used in the 11/84 (unibus only). The KDJ11-BA, -BB and -BD is marked as Q-bus only, and only 11/83. The KDJ11-BF is the final version, and is marked as working in both 11/83 and 11/84 (both Q-bus and Unibus). Of course there are other problems as well, such as the FPJ-11 socket on some versions, as well as speed.

Does anyone know for certain that this backplane it compatible with MSV11-J modules, and if so in which slots they would go?

AT & T UNIX pc's

> I have a 7300. I've come to learn a bit about the 3B1, > which could be considered the same thing (?). Pretty much. Architecturally, they're the same. The usual distinction is the 3b1 has a "hump" to accomodate a physically larger disk drive. There has been a suggestion, though debated, that the 3b1 also has a beefier PS. > I have a load of disks and docs for the 7300?. > Unfortunately they were all stored improperly and are > worthless. Being I already have the media (and can > prove it) I'd like to have working images of these > disks. Anyone have a clue? That's a good question. Because they contained UNIX SYS V R2, most everyone was pretty careful about throwing around copies. So I don't know of any online images of them. Your best bet might be to find someone who has a set they'll send you, or perhaps a set they've backed up. In general, the first place to look is Peter da Silva's page: http://unixpc/taronga.com > My hard drive does work, but is a bit flakey maybe :( There's a classic issue of corrosion on the PS connector.

I used to do quite a lot with them, but haven't fired one up in probably 5 years. I used to maintain the archive that Peter maintains now. BLS

Offtopic-ish: Classiccmpers in Yorkshire?

by gpearce＠curiousgroup.com

Hi folks, I'm going down to the Citro?n Car Club rally in Wetherby this weekend. I wondered if any classiccmpers fancied meeting up at some point. ISTR there's a few in that part of the world... Gordon
