Okay, I admit it: There are many, many things I don't know. :) And one of those things came up in a conversation today, and sheer curiosity leads me to ask: What, exactly, is a resonant transformer? The subject came up here about a month or so back - I think it was in reference to a DEC PDP-8/E power supply, but that could be a mistake - and a look through Google seemed to only bring me sites about Tesla coils, which was interesting but didn't really shed light on the subject. So I'm still curious. :) What does a resonant transformer do that a conventional one does not? Does it have usefulness outside of Tesla coils? What would it be doing in an 8/E (or whatever machine it was that was being discussed at the time)? Any enlightenment appreciated. :) -O.-

Norsk Data Nord-10/S restoration effort on the way!

by toresbe＠ifi.uio.no

Allright, so I'm going to the movie theatres to watch Fahrenheit 9/11 (this was probably about two months ago). The movie theatre I pick also happens to have a conference centre at the lower floors. I'm bored, the movie doesn't start for 40 minutes, so I go down and behold the exhibit I hadn't looked at since sixth grade or something. The conference center, as the exhibit, is owned by Storebrand, a major insurance company here in Norway. (Storebrand literally means "Big fire", hee hee) And the exhibit is full of cool old office hardware (old IBM dictaphones, mechanical cardpunches/sorters, etc). And amongst one of the cards, I see a COBOL card - PICTURE XX99. Ah ha! The smell of opportunity! And old punch card paper! (*sniff* Ahhh...) I call around, and finally end up talking to a man named Dag Wold, who is the archivist and historian at Storebrand, and he explained that he was a retired insurance worker that kept tabs on the archive's inventory. So, finally, I get to come over and look. And what a sight! Apart from a metric buttload of cool old mechanical stuff and dictaphones and stuff, a cool IBM 3270 terminal (I think I'm gonna start a thread on that too :), a VT102 (what was the 2 for, again?), and a nice TI mini I tried but failed to boot (The floppy I tried probably wasn't the boot floppy), and some other cool stuff I really should take pictures of, the crown jewel of the collection was definately (IMO :) a NORD-10/S minicomputer with a 9-track Pertec rebrand tape drive. /S means "With various enhancements, like cache" in Norwegian. Terse language, you see. :P It's in excellent cosmetic condition. I powered it up, and everything seemed to be working, but seeing how I don't know the first thing about pretty much anything from Norsk Data, "working" means "didn't burst into flames" :) Enter Johnny Oddene, the webmaster of sintran.com, ex-Norsk Data-employee, hobbyist, and owner of what was left of ND after they went bankrupt in 1993. (Pretty much just a warezhouse and a trademark) I mailed him, told him a bit about the project, and asked him if there was any documentation or anything availible. He wanted to see the thing, and we decide to meet up at the Storebrand warehouse. He powered it up and started toggling and talking with me about the architecture. And what an architecture!! The most interesting feature is the concept of levels, which was new to me. The CPU had 16 levels, 0-15. A 'level' was pretty much a sort of what IBM would call PSW and Intel called ..was it TSS? Anyway, it describes a running task with all its registers. The interesting thing, is that the registers that you'd normally get from RAM with a Load PSW isntruction or an <Insert Intel equivalent> are actually registers inside the CPU! You just do a level switch, one instruction, and it switches levels and immediately continues the other level! Of course, with what ISTR being 6 GPRs and some things like PC and stuff, this would end up with a lot of registers. But boy, was it fast! In fact, some customers buying the ND-100, the sequel to the Nord-10, noticed a significant decrease in performance due to this. It also would BOOT OVER NETWORKS! IN 1972! In what was called OPCOM (IIRC), which was a small bootloader in PROM, you could boot from various devices. It used to have a disk, but now it doesn't :\ I am impressed at how much he remembered about the machine. Reading his homepage, I find that this was the first computer he used (And the first is always special... I envy him starting on such an ingenious arch instead of a sodding 286 like me) He didn't, however, remember any instructions, so no toggling yet. You could also tell the thing to boot from floppy using a terminal over current loop. However, being the owner of the friggin' company, he of course has a complete set of docs! And a terminal! Yay! He's promised to call me when he's heading up to his warehouse so I get a peek, too. I will of course take pictures if I can get to borrow my (What do you call people living in the room next to you at an orphanage? Neighbour?)'s CyberShot. I will of course start a webpage on this. For people wondering, the PDP-7 is still where it's always been, and waiting for a wire-wrapper. Thanks in advance for all the help you all probably will give me during this project ;) With excited rgds, -- Tore S Bekkedal <toresbe(a)ifi.uio.no>

Q.: Resonant Transformers

by aek＠spies.com

what you want to google for is "ferroresonant power supplies" http://www.mcitransformer.com/i_notes.html for example A ferroresonant power supply is very similar to an unregulated power supply except for the characteristics of the ferroresonant transformer. The ferroresonant transformer will supply a constant output voltage over a wide variation of the transformer input voltage. The problems with using a ferroresonant power supply include that it is very sensitive to slight changes in line frequency and would not be switchable from 50 Hz to 60 Hz, and that the transformers dissipate more heat than conventional transformers. These power supplies are heavier and will have more audible noise from the transformer resonance than regulated linear power supplies.

DEC Stuff available in MA ... Part #1

by richard.beaudry＠gmail.com

Hello all, My company recently decommissioned a small DEC system. They were going to scrap it out, but the person who became the "owner" of the system was loathe to do that, as it was a working system. I spotted the pile of stuff, and asked about its status. Long story short, I am now the owner of the system. However, I know *ZERO* about DEC stuff, so I thought I would make it available to the list. I don't know if the pile represented a single system, or half a system, or what, but it is better than dumpstering it, right? :-) This is only part of the list -- the "small stuff" if you will. The "big stuff" is still waiting for me to go and get it. Once I get it and look it over, I will list it here as well (as a teaser, think B400X, R400X, TS05, RAID array, and MicroVAX). First, the brief rules: - Everything is free if you come get it (Westminster MA, USA, ZIP code 01473). If I ship it, I ask shipping +20% (for my time). "Shipping" includes postage and packaging materials. I buy all of my boxes, etc., at Staples... Please don't ask me to go 50 miles out of my way to get a cheaper box :-) - Please email me *off-list* to indicate yout interest. I will take emails up until Monday 11/15 at midnight, to give weekenders and international folks time to see this. I will decide who gets what in the event of multiple interested parties. I will email the lucky ones sometime on Tuesday. - I will try to answer all questions to the best of my abilities, but remember, my knowledge of DEC systems is less than zero.... OK, on to the stuff: - Terminal, VT-420 C2, manufactured 7-Aug-1990. Amber screen, passes diagnostics on power-up. Screen is kind of dim, and also "wavy" (letters move back and forth at high frequency). Also will need a good cleaning. Has a keyboard attached, LK-401-AA, rev. A02. Keyboard is also quite dirty, but appears to be functional (F3 brings up config. menu, and I could navigate w/ keyboard) - Terminal, VT-320 C2, manufactured 31-Aug-1990. Amber screen, bright stable picture, some burn-in, but not too bad. Startup diagnostics pass. Will need a good cleaning. Has attached keyboard, LK-401-EA, rev A04. Keyboard dirty, but functional. Has a WordPerfect template stuck on above the top row of keys. Again, F3 brought me to config, and I could navigate w/ keyboard. - Terminal, VT-520 C4, manufactured 1994. Amber screen, clean, but definite screen burn. Status line is badly burned in, and screen shows signs of other burn-in. Startup diagnostics pass. Has attached keyboard, LK-411-AA Rev B01, dirty but functional. I was able to bring up config and navigate w/ keyboard. - Terminal, VT-520 C4, manufactured 1994. Untested, because it is still in its original box. The box is opened, but the styrofoam packing is there, and the terminal appears still sealed inside the blue plastic bag it was shipped in. Base is also included, but NO manuals or keyboard. - DECServer 200/MC. Has a 15-pin Ethernet connector and 8 DB-25 male connectors. Also says Model: DSRVB-A. Untested, but working when pulled. - ThinWire Ethernet Singloport Repeater-150. DESPR-EE, rev C02. Looks cleam, missing rubber feet. Untested, but another working pull. - M9404-PA card. Full-height card. Half is just a plastic spacer, the other half says "Q22 Cable Connector". Untested. - M9047 Grant Continuity Card - Manual: "B400X Expander Installation Guide" - Manual: EK-BA44A-IN, "Entry Systems, BA400-Series Enclosures, Storage Devices Installation Procedures" (TWO copies) - Manual: EK-BA44A-IN-003, "Entry Systems, BA400-Series Enclosures, Storage Devices Installation Procedures" - Manual: EK-RF72D-UG, "RF Series Integrated Storage Element User's Guide" - Manual: EK-RF72D-IM, "RF Series Integrated Storage Element Installation Manual for BA200-Series Enclosures" - Plugs, possibly for setting Drive IDs, or Bus IDs? Part Number: 12-28766-19 REV A01. Three plugs with no ID, the rest numbered 0-7. One full set, one with blanks and 0,6,7 only. - Plugs, possibly for setting Drive IDs, or Bus IDs? Part Number: 12-28766-28 REV B01. Three plugs with no ID, the rest numbered 0-7. One full set, one with blanks and 0,5,6,7 only. - FIVE covers, look like they cover hard drives. 7027049-02, Rev. A01 Thanks! Rich B.

Shipping a Model 33 (RO) Teletype

by wmaddox＠pacbell.net

I've bought a model 33 off eBay. The seller doesn't really know how to ship one -- he's just got it in a box with styrofoam peanuts. I'm trying to give him some instructions on how to do it right. I recall that there is a shipping screw that must be locked, but don't remember the details. Can anyone give me some instructions I can pass on to him? If anyone has shipped one of these, I'd like to know what worked and what didn't. I remember a few stories of machines damaged in transit showing up on the list. Thanks, --Bill

one more question about pdp8/e console switches behaviour

by GOOI＠oce.nl

Thanks all for the explanation. I have put some new pictures on my website (www.pdp-11.nl) Goto [Homebrew 'PDP-11'] -> [spin off]. To get the LED's on the photo the colors of the artwork are not correct; the smal picture above it is more like it. The latest source code is available in the ZIP file (and with and without RealConsole in the two S19 record files). The S19 without RealConsole will run stand-alone on the Core Board (no I/O Board needed) if the 32k RAM chip is installed. I will certainly check out David's PDP-8 online. Cool! greetz, - Henk, PA8PDP. -----Original Message----- From: cctalk-bounces(a)classiccmp.org To: cctalk(a)classiccmp.org Sent: 11-11-2004 18:32 Subject: Re: one more question about pdp8/e console switches behaviour I think people have answered your questions but if not my online PDP-8 interface should work like the real front panel.

I have never done this myself, however it is reported by many to work on Toshiba laptops: ----------------------- Begin Quote ---------------------- This method works on all older (ancient) models. This is what you need: 1. Your notebook 2. An empty formatted diskette (720 kb or 1,44 mb) 3. A second computer (e.g. a DOS desktop PC) 4. A hex-editor (e.g. Norton DiskEdit or HexWorks) This is what you have to do: 1. Start the desktop PC and start the hex-editor 2. Put the disk in drive A: 3. Change the first five bytes of sector 2 (boot sector is sector 1) to: 4B 45 59 00 00 4. Save it! Now you have a KEYDISK 5. Remove the disk from drive A: 6. Put the disk in the notebook drive 7. Start the notebook in Boot Mode (push the reset button) 8. Press Enter when asked for Password: 9. You will be asked to Set Password again. Press Y and Enter. 10. You now see the BIOS configuration where you can set a new password. Of course this will only work if you can still boot the machine. Newer models try: Toshiba notebook BIOS password removal via Parallel Port If you make a simple device that you connect to your parallel port, a lot of Toshiba computers remove the password when you boot it up. The device, named "loopback" by some, could be made out of any parallel wire with 25pins connectors. You should connect these pins: 1-5-10, 2-11, 3-17, 4-12, 6-16, 7-13, 8-14, 9-15 For those who care, what is connect to what 1-5-10, 1=Strob, 5 =data bit 3, 10 = ack 2-11, 2=data bit 0, 11=Busy 3-17, 3=data bit 1, 17=SLCT IN 4-12, 4=data bit 2, 12=Paper End 6-16, 6=data bit 4, 16=reset 7-13, 7=data bit 5, 13=SLCT (out) 8-14, 8=data bit 6, 14=Auto feed 9-15 9=data bit 7, n/c sometimes +5v If you have a newer laptop again, one without a parallel port you will need a special USB password removal tool, and they cost much more. ---------------- End Quote ---------------- If you give up on it or otherwise decide to unload it, I have some interest (located in Ottawa).

Hold the scanners

by Watzman＠neo.rr.com

Re: "Obviously the value would be greatly enhanced if we could knock up an index (document title or part number, where it starts, where it ends) and better yet if individual docs could be pulled out into separate pdfs." All of this is fairly easy if you have full-version Adobe Acrobat. I'm not saying it's not time consuming, but it's far less difficult than many people (who have never used full-version Acrobat, but have only used the reader) would suspect. I MIGHT do it if I get access to the files. Downloading 1,000 jpegs will probably take a lot more time than consolidating them into a PDF file, which can then be fairly indexed.

Linux OS

by millenniumfalcon＠cableone.net

I have been ready for 20 years to dump "Uncle Bill" but every time I try to switch to Linux I run into problems that seem insurmountable. Recently I have been looking at the Linspire line of products...Lindows in particular. It looks like what I need, BUT....just as always, when I ask about compatibility with the various applications that I now run under XP I get the same run-around. "Get it and try with Wine and see if it works." If I have to get drunk first, I am not interested...#8-) I can't do that. There are programs I need and I cannot just take a chance that "maybe it will work" My main concerns are Adobe PDF creator, Adobe Photo Shop, Netscape, and particularly Easy Office 2001 which contains all my data in Easy Spreadsheet files that are not compatible with Excel (even though they are supposed to be). I don't want to have to go out and buy an all new set of apps. That makes the relatively low price of Lindows immaterial. And besides, all my files would likely be incompatible so I lose all my old data unless I keep two machines. Also, I use Netscape for browser and E Mail and I have tons of mail files and bookmarks that I would have to figure out how to get over to Lindows...Unless Netscape will run under Lindows. ???? I know there are free apps that can do word processing and spreadsheets and photo processing, but they appear to be "stripped down" versions. I can network the old and new computers ( I already have the LAN in operation with two MS OS computers on it) then I could download all my files and programs into the new computer....IF I COULD BE SURE that they would work with the Lindows OS. Spending $49 to try what might be a failure is NOT an option. Does anyone have any suggestions other than buy it and hope it works?

Hold the scanners! (was DEC Docs, Diagrams, and Diags. on Microfische)

by vaxlion＠postal.lionsden.com

Hi Folks, Long time lurker, first time poster here. I'm the seller of the microfiche collection up on ebay. I apologize that I haven't jump in here sooner and talked about this. The collection HAS been scanned into a ~4GB set of jpegs and tiffs. A professional scanning company was used: www.data2cd.com. At the time, over 2 years now, they were the cheapest and scanned per microfiche. Due to time constrains, absent-mindedness, and bandwidth limitations, I haven't made the files available. The scans are only organized into pages per microfiche... no other sorting or labeling has been done. In some cases, there are more than one set of documents present on a microfiche. There are some pages were data2cd was not able to extract enough detail. Either the density was beyond their equipment and/or the original page was not transfered/photographed correctly. I'd be very happy to flood someone's connection for a weekend to transfer the files over with the promise to organize and host the files for the general vintage computing public. Ideally, it would be nice to have these organized into PDFs. Also, it would be nice to throw some files at an OCR to extract the diagnostic source code. My recommendation is to bet on the auction if you have a desire to collect such material and can preserve it. Please don't bet with the only intention to scan these -- that's already been done! -- Michael

Straight-8 spotted on James Burke's "Connections"

I was watching "Connections", (either ep 4 or ep 5 - "Faith in Numbers" or "Wheel of Fortune", when about 3 min into the show, James Burke fires up a Straight-8 w/LED front-panel lights, and at least a couple of DECtape drives, all to control a planetarium. I just about fell off the couch! http://www.documentary-video.com/displayitem.cfm?vid=854 -ethan P.S. - to make this doubly on-topic, I was watching this on Betamax.

It's best to know what model PS/2. If it's a 95xx, it will be much easier and even fun to set up.

Hold the scanners!

by aek＠spies.com

> outstring (1, "Make multiple copies!\n"); about 700mb (~200 sheets) are on bitsavers after about 2.5 hours. they are in a hidden directory that the ftp mirrors will pick up. i'm guessing it will be some time in the early morning when the transfer finishes. the good news is the diagnostic listings look OK. the bad news is they were scanned with an effective resolution of 200dpi, which is going to make it very iffy to OCR. bundling the diagnostic listings into pdfs combining multiple sheets and adding page numbers should be fairly easy to automate.

VINTAGE COMPUTER HOBBYIST COLLECTION

by rich_bramante＠yahoo.com

I am forwarding this from the Boston Craigslist in case anybody is interested. Reply to: anon-48640258(a)craigslist.org ================================================================= I have a 5x10ft storage locker with 24 years worth of computing, but now I am moving and have to get rid of it. You can keep this in your own collection or sell it on eBay. Help me clean it out within the next few weeks by taking all of it. To keep it serious I'll accept offers for one week. If no offers, not even token offers, I'll take it all to the dump myself. I have a pickup truck and can help transport if you pay gas. Located and available to be seen in Londonderry, NH, at exit 5 off Interstate 93. Little of this stuff is usable in a modern environment, but it all worked when taken out of service. Apple //e. Monochrome and 13-in digital color monitors, 5MB Corvus hard drive, Imagewriter 1 printer. Many cards and accessories. Complete Apple Pascal and Modula-2 system. A whole bunch of software and manuals. Macintosh Plus. 20MB hard drive. Many accessories. Software and manuals. Compaq II 80286 portable computer with 20MB hard drive. Canon 8086 computer and monitor. 80286 IBM AT clone with monitor. All these would make good Minix systems to toy with. 8088 computer and monitor with floppy drives. 80386 DOS laptop. HP Omnibook 300 ultraportable Windows notebook. Sun IPX Solaris UNIX workstation with disk array, 19-inch color monitor, keyboard, mouse. HP Laserjet 3P (needs board). A couple of Epson inkjet printers. A couple of Microtek SCSI flatbed optical scanners.

I think it's incredibly cool--just like the various emulations from the paper versions to the simulator versions to the real copies. They all took a great deal of thought and planning. "Dissing" something like this reminds me of when I still had a shot at flying for my once great company. One of the chief pilots in charge of (pilot) hiring had _nothing_ good to say about simulators at all. He especially _hated_ any PC version of a fltsim. In point of fact, ual had one of the best pilot training programs on the planet, and guess what(?), like all airlines, they train in the sim (full motion, awesomely realistic). The final checkride is in the real thing (to my knowledge, the final checkouts were done on revenue flights). Sims must not be all that bad, eh? Not everyone has access to full motion sims--in fact, almost no one does... I fell in love with the first sim I ever saw. It was a "terrain modeling board" based T-37 full motion sim. Later, we got to fly the cgi versions (which were nightime only, due to the limited graphics capabilities available when they were made). T-38 sims were all cgi based (No mechinal stuff to break down, and it was the instrumentation that they were interested in). In 1980, this stuff seemed "spaced-aged" (esp. the cgi sims, which were crude by today's standards). I've been following PC based fltsims since the early days (and they really were crude by today's standards). There are those who still have nothing good to say about PC-based sims, but I can't say enough good about them. Apparently, a difference in perception... (And, yes, I acknowledge that there is no substitute for the real thing, but they truly are one of the most efficient ways ever devised to turn gold into thin air, and they take up a lot of space and need lots of care and attention! It's definitely a trade-off...) Regards, Bob Greenstreet

New Finds: SGI Indigo Win some, lose some

by rigdonj＠cfl.rr.com

I took a brief trip out to one of my scrap^H^H^H^H^H er, treasure sources today. I didn't expect to find much and I wasn't disappointed if you catch my meaning. However I did find a loose board that looks suspiously like a SGI Indigo board which surprised me because I've never seen any Indigo stuff at this place. I brought home the board and checked on the net and found that it's fairly rare card for the Indigos. It's Real Time Video Capture Card, pn 030-8095-003. But unfortunately it's in really bad condition, something heavy was dropped on it and the board is cracked and at least one surface mount IC is broken in half :-( But the good news is that I also found a floppy disk drive in a SGI sled and it appears to be the right one for the Indigo. The one in my R4400 Indigo is flaky so the trip was worth it after all. Joe

Scanning books

by aek＠spies.com

> Otherwise, the way this is handled is to shear the binding off the book. Sewn book bindings can be disassembled without shearing. Take the journals apart then scan the left and right pages sequentially. Most glued bindings and be peeled apart in a similar manner. In fact, it's difficult to keep a glued binding from falling apart if it's older than 20 years. The problem with shearing a binding is you have to make absolutely, positively sure that all of the pages are aligned, or you take a 'C' shaped cut out of the bound edge of the book. By the time you get a book down to the size where you can make sure the stacks are straight, you may as well have taken them all apart by hand.

one more question about pdp8/e console switches behaviour

I think it's perfectly logical. When you press EXAM, it increments the address ready to read the next word. When you press DEP, it increments the address ready for the next entry. Unlike a PDP-11, where sometimes it increments, sometimes not, and you have to remember the rules :-) It's just a different way of doing it. Remember this is a simpler machine, designed some years before the -11. > When you activate HALT (or SING STEP), the top row of lights > show the Memory Address (aka the Program Counter, PC). > When the knob is then set at "MD" the current instruction (at PC) > is displayed on the 'data' row of lights below the Memory Address. > So far so good (correct?). Yes, if you HALT a running program, that's correct. It displays the address just about to be used, logically, so that if you press CONT it starts at the address which is displayed, just as if you did an ADDR LOAD of that address, and then pressed CONT. > When you press EXAM the *first* time, the data still shows what > is at memory location [PC], but the Memory Address shows [PC+1] ... Yes. It shows the word at the address that was displayed just before you pressed EXAM. Having pressed EXAM, it then displays the next address. > That would mean that the displayed data and the displayed Memory > Address *can* be out of 'sync'. Only after you pressed EXAM at least > once you are sure that the displayed data is from location minus one > from the displayed Memory Address. > Is my understanding correct? It's not really out of sync. When running, or after a HALT, and BEFORE you tamper with any switches, the display shows the current address and the data at that address. Which is probably what you want, most of the time. If you then press EXAM, you will get the data from whatever address was current (and displayed) just before you press EXAM. If you press DEP instead, the data you write would go to the address that was current, and displayed, just before you pressed DEP. When you press either of those keys, the address is incremented ready for the next EXAM or DEP. > Other question. > Is the increment after EXAM (and DEP) *always* done on the pdp8/e? It's always done. It's done as you press the switch down. > The reason I'm asking is that on PDP-11's the repeated sequence > EXAM / DEP / EXAM / DEP, etc. does *not* increment the address. > Address increment is only done when EXAM is pressed after EXAM > was pressed. Likewise for a DEP / DEP sequence. PDP-8 users get the DEP right the first time, and don't need to check it ;-) -- Pete Peter Turnbull Network Manager University of York

Shipping a Model 33 (RO) Teletype

by brian＠quarterbyte.com

Definitely do not let them ship it in a box filled with peanuts. With a heavy object, some sort of liquefaction occurs and the object bangs around inside the box. Poured foam can work if the thing is sealed in a plastic bag. I've had very good luck when the shipper has used pieces of rigid styrofoam, even scraps broken up from the large styrofoam castings used to ship monitors or computers, fit tightly on all six sides of the object being shipped, leaving no empty volume. I just received a paper tape punch and reader from the Netherlands shipped this way and there wasn't a crack or scratch.

Subject: Toshiba T4400 password

by Watzman＠neo.rr.com

Yes, it's not too difficult to remove passwords from older Toshiba models. There are 2 ways, basically. One uses a dongle on the parallel port, the other uses a floppy diskette with some magic bytes in a particular place on the disk. Both the dongle and pre-made floppies are sold on E-Bay. With a bit of effort, you can track down information on how to make either yourself.

I think people have answered your questions but if not my online PDP-8 interface should work like the real front panel. It is a real 8/E but the web interface is a custom board I made. I copied the front panel logic so it should act the same and it seemed to in my testing. http://www.pdp8.net/run.shtml David Gesswein http://www.pdp8.net/ -- Run an old computer with blinkenlights.

one more question about pdp8/e console switches behaviour

by GOOI＠oce.nl

Hmm, is that behaviour of a real pdp8/e console logical? I am not saying it is wrong; perhaps the impementation DIGITAL made is a little strange ...? When you activate HALT (or SING STEP), the top row of lights show the Memory Address (aka the Program Counter, PC). When the knob is then set at "MD" the current instruction (at PC) is displayed on the 'data' row of lights below the Memory Address. So far so good (correct?). When you press EXAM the *first* time, the data still shows what is at memory location [PC], but the Memory Address shows [PC+1] ... That would mean that the displayed data and the displayed Memory Address *can* be out of 'sync'. Only after you pressed EXAM at least once you are sure that the displayed data is from location minus one >from the displayed Memory Address. Is my understanding correct? Other question. Is the increment after EXAM (and DEP) *always* done on the pdp8/e? The reason I'm asking is that on PDP-11's the repeated sequence EXAM / DEP / EXAM / DEP, etc. does *not* increment the address. Address increment is only done when EXAM is pressed after EXAM was pressed. Likewise for a DEP / DEP sequence. again, TIA, - Henk, PA8PDP. > The position is always relevant, but you don't set it to AC. You set > it to MD (Memory Data).

one more question about pdp8/e console switches behaviour

by GOOI＠oce.nl

Thanks very much for the clear answer, Pete. I have a webpage "in development", and hope to add a few pictures representing the latest state of affairs. There is also a ZIP file but it is an old version ... I will clean up the current source (remove some debugging stuff) and make that available for download as well. If you have a working Core Board *with* the extra 16k RAM chip, you can run the pdp8/e simulation without the I/O Board by just assembling the source with the "RealCons" conditional set to 0. The wiring details (and more) are all in the source file. The link to the page is: www.pdp-11.nl -- the click on [Homebrew 'PDP-11'] in the menu at the left, and on the page that opens click the link [spin off] at the top right. enjoy (?), - Henk, PA8PDP. > -----Original Message----- > From: cctalk-bounces(a)classiccmp.org > [mailto:cctalk-bounces@classiccmp.org]On Behalf Of Pete Turnbull > Sent: donderdag 11 november 2004 9:08 > To: General Discussion: On-Topic and Off-Topic Posts > Subject: Re: one more question about pdp8/e console switches behaviour > > > On Nov 11 2004, 8:32, Gooijen H wrote: > > Hello all, > > > > I have the pdp8/e *including* the console running on the Core > > 6809 Board (plus one I/O Board)! > > Nice!
