Whitechapel MG-1 : dead power supply ?

by bernd＠kopriva.de

Hi, since two weeks, i own a Whitechapel MG-1 ... ... unfortunately, i did not succeed in starting the machine. It seems, that the power supply is defect, as i've blown 3 fuses :-(. Does anyone have the schematics for the power supply, or maybe know the specs for it, so i can replace it ? Especially, i don't know, what the O2 output means ... Thanks alot Bernd Bernd Kopriva Phone: ++49-7195-179452 Weilerstr. 24 E-Mail: bernd(a)kopriva.de D-71397 Leutenbach Germany

Reply trimming and HTML posts

by dave＠mitton.com

errr, can some people PLEASE start trimming their replies, particularly for one-liners??? Also, those people that post HTML; It's really nice that the list processor strips them out, and creates a web page and inserts a link, but I just skip by most of them. If you want to be read, post ASCII. Thanks, Dave (bad enough email bandwidth is wasted with spam).

Perhaps you are right; perhaps not - but any such claim of equivalence either springs from ignorance or from linguistic shorthand; anyone, professor or not, who persists in claiming such equivalence after having had it pointed out that real computers have finite storage is simply _wrong_. And in any case, I don't see how what you wrote has anything to do with my point, which is that what looks like a Harvard architecture when considered from one point of view may look like a von Neumann architecture when considered from another, and that restricting yourself to points of view which include the possibility of code-which-writes-code (I hesitate to call it *self*-modifying code) is unnecessarily restrictive, not to mention contrary to the usual uses of the words to the point of being confusing. >>> Also, remember the features of some languages, like APL, which will >>> operate on von Neumann and Harvard architectures, and which APL >>> code might include the execute operator, which facilitates run-time >>> code generation and execution. >> In the sense of "code" for which the underlying CPU is a von Neumann >> or Harvard machine, the execute operator does not necessarily imply >> run-time code generation. > It is disengenuous, and intellectually dishonest, to use a lack of > implication to assert a lack of occurrance. That's not what I was trying to do at all. I read your statement about APL both (a) running on both von Neumann and Harvard architectures and (b) including the execute operator as implying that (c) both vN and H architectures can do run-time code generation. My point was that this implication is false: execute does not require run-time code generation, so (c) does not necessarily follow from (a) and (b). > In truth, there is no logical difference between a hardware based > mechanism of computational processing, and a software based mechanism > of computational processing. There is when you are drawing distinctions based on whether the hardware can modify its own code or not. For example, it is likely that the machine I'm typing this on is microprogrammed with mask-programmed microcode ROM, in which case the real hardware is a strict Harvard architecture, with no possibility whatever of code-that-writes-code. Based on what you've written, it seems to me that this implies you do not think it is reasonable to call it a computer. [more "William R. Buckley" <wrb(a)wrbuckley.com>, another message] > Neither can you alter the microcode of the x86, yet it is the essence > of a computer. This makes it appear that you do _not_ think that being able to alter code is necessary for something to be considered a computer. I'm becoming confused about what your stance actually is here. Perhaps your position is that it is necessary for there to exist some level of abstraction at which code-that-writes-code is possible for something to be considered a computer? If so, it's not at all clear >from what you've written. ["Brian L. Stuart" <blstuart(a)bellsouth.net>] > (Almost no authors highlight the distinction between unbounded and > infinite. [...]) Well, not when writing about computation, at least. :-) This is probably because it's a very subtle distinction, one which I'm not convinced even exists for some models of infinity, and one which makes no difference whatever for (almost?) all uses. > Now here I do agree with the desire to define a computer in terms of > machines that can compute functions that are computable in a > Church-Turing sense.

Very nicely put - and aside from leaving analog computers out in the cold, I think I basically agree with it. > Notice that with the definition above, any computer can implement a > universal Turing machine and [...] such a machine can modify it's own > programming. Only after you make the shift from the universal Turing machine itself (which has fixed code) to the specific Turing machine being simulated by the uTm - and not then, even, if the Turing machine simulator is simulating the sort of Turing machine I studied, which has fixed code, set when its state transition table is designed. (The simulated machine's code (= state transition table) may change from one run of the simulator to the next, but not during a run.) > (Remember that a universal Turing machine interprets instructions > read from the tape.) Yes, and the tape may change - but that doesn't constitute changes in the code being executed by the simulated Turing machine. [Back to "William R. Buckley" <wrb(a)wrbuckley.com>] > I did not contradict myself. I admit fully that the ideal TM has > infinite memory. I also note that typical, contemporary computers > are not exactly a TM. Yet, they are computationally equivalent, Not if there are computations that can be performed on one but not the other. And there are computations that can be performed on a Turing machine with infinite - or unbounded - tape which cannot be performed on any existing, or foreseeable, computer. (As an example, consider computing Ackerman's function with arguments 100,100.) Therefore they are not computationally equivalent. [more "William R. Buckley" <wrb(a)wrbuckley.com>] >>> The important point for computation is closure, [...] > In the case of Turing closure, the notion is much broader. Turing > closure refers to the ability of a system to perform any and all > computations that can be expressed. This is not a prticularly interesting notion, as what computations can be expressed depends on your expressive notation. For example, if I choose the notation of real analysis and calculus, there are computations that can be expressed fairly easily which cannot be carried out by a Turing machine - because the Turing machines cannot work with real numbers, only discrete approximations to them.

Anyone want a Dandetiger or two?

by bob＠copenhagen.cuug.ab.ca

I have two Xerox 1108 machines with the souped-up processor, colloquially known as a "Dandetiger". Both were working until a few months back when I finally moved everything I really needed onto a somewhat more modern machine. The hard disk drives are starting to make dry bearing kind of noises and may be a little hard to boot, but otherwise seem to work OK. I was having some problems with the floppy drives, but maybe that's just because all my 8-inch floppies are antiques. The monitors work well, except that I think there must be a sloppy connector somewhere: sometimes they sit silent for several minutes after power-on before suddenly making the flyback noises and coming to life. In addition to the basic machines I have a couple of "busmaster" cards, which allow the Mesa bus to be plumbed into a PC extension or multibus chassis. I have the source code releases (on floppy) for Intermezzo, Koto, and Lyric, and Koto Beta NoteCards. I also have copies of the LispUsers and Library files, the Koto source files, and floppy images taken before I started having problems with the floppy drives. In theory it is therefore possible to ftp this stuff back to one of the machines and remake the floppies as good as new. Assuming the RIAA doesn't sue me for copyright infringements I will be happy to supply CDs of this stuff to anyone who needs it. There is also a shelf full of manuals (1 set only) and assorted notes I have acquired along the way. Anyone interested in giving them a good home? I will give them away for the cost of shipping. Truly I am going to miss these machines, but I can't really afford the space to keep them, or the time to tinker with them. I don't always keep up with this list, so if you are really interested please e-mail me directly. | "... both Republicans and Democrats stood Bob Bramwell 60 Baker Cr.

Sharp MZ-80K Power Supply Question

by kevan＠heydon.org

Hi A couple of days ago the power supply on my MZ-80K released its magic smoke (a rather nice red colored smoke at that!) from capacitor C501. The machine carried on working throughout, although I did power down as soon as the smoke release was seen/smelt. So the question is, does anybody out there got documentation or can easily get inside their 80K PSU to find out the value of this capacitor so it can be replaced with a new one. Many Thanks -- Kevan

Dec Rainbow prehistory

On 11/18/2003 01:23 AM -0600, Tom Jennings <tomj(a)wps.com> wrote: Tom wrote lots of good things... >Some BOZO designer had, I assume arrogantly, put all the video >interrupts (vert, horiz retrace, etc) starting at 00020h, which everyone >knows is where MSDOS has it's software interrupts. They were in a PAL or >something, and could not be moved. Well, I won't defend the quirks of the Rainbow... (more later) But you're forgetting that the Rainbow 100A design pre-dates the IBM PC, it was first designed as a CP/M machine. MS-DOS came later. And IBM put interrupts on the PC in places that Intel's data sheets documented as RESERVED! IBM did not pay attention to Intel's recommendations and violated a few of their support device allocations. DECnet-DOS was developed in the DECnet group inspite of the Rainbow group at first. Their marketeer felt that Corvus Omninet was going to be the big thing. Only later did we integrate when they got into LAN Manager support. Our first target was the IBM XT with a 3Com 3C501 Ethernet board, and the Rainbow running DDCMP on the serial port. We weren't going to wait for the Rainbow-150 which would be a more industry compatible system. When the IBM AT appeared, that scotched the RB-150 and lead, eventually... to the VAXmate. (Thank KO for the delays) I remember the MHFU watchdog and the Vertical Retrace Interupt. The DECnet kernel basically ran as an interrupt driven background TSR. On the IBM PC we easily shelled off the 1C clock tick, but on the Rainbow, we had to build "clever" reentrancy shells around several interrupts to avoid some wierd stack overflow or reentrancy into the video BIOS. The Rainbow at least had a decent UART with a multicharacter FIFO. I had no problem doing 19.2kbs using C routines. That stupid XT UART could barely do 9600 with an optimized state driven assembly routine. UART FIFOs didn't appear until the IBM PS/2 Model 50. Dave (has two HP16Cs and runs the wprn program)

OT: Need power pinout for Dec Hinote Ultra II

by ian_primus＠yahoo.com

I know this isn't on topic yet, it's not old enough, but I thought I'd check here just in case. I recently ran across a really cute little laptop. It's a Digital Hinote Ultra II model P8X. Unfortunately, I don't have the power adapter for it. It uses a small, three pin connector. The bottom of the laptop says that it takes 11V 2.7A, but it doesn't list the pinout of that connector... Googleing didn't turn up anything helpful. So, I figured I'd check here, and if all else fails, I could always take it apart and see what that connector goes to, but I don't want to mess with taking it apart if I can help it. Laptops are always a pain to take apart and put back together... Also, has anyone had experience rebuilding the battery packs in these? Mine is no doubt dead, and I would imagine it would take standard battery cells inside. Once I get this to power up and verify that the battery is dead, I plan on rebuilding it with new cells. Thanks! Ian Primus ian_primus(a)yahoo.com

HP 2000 TSB simulated?? YES! 2000 E, and F and Access have all be en running.

by MGemeny＠pgcps.org

Hi folks, I just want to express my thanks for all of the support that I have gotten this week from the group. Thanks you all so much. It has been wonderful chatting with so many people with interest in the HP2000 product line. For anyone who I have not already told, I did start up an HP 2000 Access simulation for people to play with. Please don't invest a bunch of your time keying in things as I'm not keeping a regular backup schedule. If I have problems with it, I'll just reload it from the last backup tape image. I have a web page that has a link on it to start your telnet session and it also gives you a few tips and pointers. This will also give us a place to link to other web pages and running systems. <http://www.pgcps.org/~mgemeny/access> http://www.pgcps.org/~mgemeny/access This image has a lot of other accounts on it, and they have a lot of programs in their catalogs. If you want access to more of the system, just drop me a note. I would be glad to send you instructions on how to browse deeper into this system. From the response I have gotten I would estimate that several systems will be running 24/7 by the end of next month. So user accounts on stable systems should be available. I would also guess that we will be grooming SIMH for another 6mo or so and that much progress in recovery of libraries will take place over the coming year. And, by the way, since this thread did start out talking about star-trek, one version is in your group master account. For a listing of the group type "gro", to get a program from this list just put and "*" in front if the name. The break key is not working yet so you may want to list it and know how your going to get out of it before you run it. Please report hung port to my email. Don't be shy about it, it's not your fault, it's mine. Please don't make too much of a mess. You won't be hurting me, just preventing others from enjoying the same pleasure you had. Enjoy, and Thanks again, Mike Gemeny.

Byte Magazines

by roger161uk＠yahoo.co.uk

I have the following issues of Byte Magazine. Unfortunately, they take up a fair amount of space on my office shelves and, as a result, I am contemplating getting rid of them: despite them containing loads of good information, I just don't have time for it anymore :-( Anyway, individual copies are available if anybody has a collection with missing copies and, I am happy to send larger numbers of copies to anybody interested in them, the only provision is that postage and packing must be paid, at cost (or thereabouts), by the receiver. If I receive numerous contacts for specific copies of magazines, or for specific series I may place the magazine or series on eBay or another auction site as a means to resolving the contention, proceeds going to a local old folks home. All are in good condition, although clearly some are in better condition than others. I herewith enumerate all copies, as I do not have a complete set - certain months/years are missing.

PDP8A Questions

by nbreeden2＠comcast.net

All, I was recently given a PDP8A, it's the model with dual power supplies and the 20 slot backplane. It has both the mini-panel and the operators panel. I've been working to get the system operational and have several questions: ===== The unit won't power up, I have been able to troubleshoot this down to the Triac (D7) on the BA8-C that is used to switch AC power to the main transformer. I believe this Triac is bad. (Note: I do have AC power to T1 on the BA8-C PCB.) With the Triac bypassed the system comes up and basic items check out from the operators panel. Does anyone know what a replacement Triac part number would be? I only see what I believe are DEC part numbers. ===== In the print set for the BA8-C the circuit that controls AC power is shown, the circuit uses an opto-isolator. In the schematic one side of the opto-isolator's LED goes to J12-B2, the other side of the opto-isolator is labeled OC1-2 (OptoCoupler 1 pin 2 I assume). Does anyone know where this pin actually goes? ===== I'm assuming that the G8019 board controls switching of the AC power via the opto-isolator. Is this a correct assumption? ===== I have an RL02 controller/drive/disk with the system, what steps do I need to take to boot from this drive? I don't have an operators manual at the moment. ===== -Neil

Simple serial to ethernet question

by jpl15＠panix.com

Regarding the recent (very much info!) thread about serial to network devices, terminal servers, etc... I have a Dumb Analog Engineer Question. And my DAEQ is this: I gots a DEC PDP 11/44 sitting in my garage (heated) and I would like to have the Terminal Peripheral Devices (TPD) in my Office (O). I just want a couple-three VT-type thingies and an LA120, or 36 or whatever. So, if I understand Things: I hook N ports from the 11/44 serial farm via RS232 to the ports on the TS, thence by CAT5[some_networking_protocol] to the TS in the O, and from the corrresponding N ports ports on the O TS to the various TPDs in the aformentioned O. Right? This saves running multiple RS232 lines from the 'Puter to the Toobz, among other things - like being able to play with one's Legacy Computing Device (LCD) whilst slaving away at the Workplace.... And, if a pair of Terminal Servers is what I'm looking for - I assume 8-channel pairs are cheap? Any reccomendations for this specific task? Cheers John

Telling DECTape & LINCTape Drives Apart?

by aek＠spies.com

Physically speaking, how do you tell the difference between a DECTape drive and a LINCtape drive? -- By the time PDP12's were built, DEC was using the same transport (TU55's, later TU56's) for either format. LINCtapes are loaded on the right-hand reel, and forward tape motion is counter-clockwise. DECtapes are loaded on the left-hand reel and forward tape motion is clockwise. The only other gotcha is the timing track is the opposite polarity between the two formats.

DEC Equipment

by ohh＠drizzle.com

I mailed this off to Phil Spanner in reply to his post, and just realized I forgot the CC: I meant to give to the list. :) So here goes: ---------- Forwarded message ---------- Date: Fri, 21 Nov 2003 11:10:21 -0800 (PST) From: O. Sharp <ohh(a)drizzle.com> To: Phil Spanner <pspan(a)amerytel.net> Subject: Re: DEC Equipment Hi! Thanks for your posting to the ClassicComp mailing-list: > A company that has been in the depot repair business of DEC equipment, > for the last 20 years, is about to shut down their repair lines for the > DEC equipment. They obviously have prints, diags and test beds that > they are going to be selling. I'm sorry to hear they're going out of business. My condolences. [Late note: on re-reading this, I just realized it looks like only the DEC repair line is shutting down, rather than the whole company. <slaps forehead> Aiya! Silly me.] I have kind of an unusual question. If this company, which has been repairing DEC computers, is going out of business, it may mean that their customers, having one less service option available, might soon consider retiring whatever DEC machines they're presently using. I'm currently looking for a PDP-12, and would hate to see one end up being scrapped in the belief it was no longer useful. I don't doubt that other DEC machines and other ClassicComp posters could make useful connections as well. Soooo... my question would be: Does the company have any idea what their former customers are considering doing with their equipment, and if any _are_ considering selling or scrapping - most particularly the older DEC models, which are becoming of historic value - could those customers somehow be made aware of the ClassicComp community's interest in older equipment before they take irreversible steps? I realize that may not be the sort of question you were expecting. :) Nonetheless I'd appreciate it if you could consider it, and see if there might be some sort of appropriate way to address it. ...On a much simpler note, if you have anything PDP-12 or DECTape-related hanging around the warehouse, I wouldn't mind the chance to put in an offer. :) :) Thanks very much for your time, and for making yourself known to us! It's appreciated! -O.-

I wasn't told even this much back then!! We weren't told. I/we had to figure it out. It became quickly apparent there was a problem, and only by debugging around the system did we figure out what to do. The VR routine re-enabled interrupts and continued doing video memory things. If you interrupted it, for say comm I/O, and then re-enabled interrupts yourself, and you did not return to it by the next VR interrupt, it would corrupt itself as it wasn't written for reentrancy. How we dealt with this, changed over time, as some of my team got "cleverer" in later releases. But even if it could be made re-entrant, you really want it to run to completion instead of stack up anyways. A semaphore shell on that interrupt routine, and cross-checking this flag in our other interrupts, would make sure it was done before we did any major time consuming work with interrupts re-enabled. ohh gawd, you woke the forgotten memory of the shared HW/SW interrupt vector.... noooo ...

Hello to all, This is my first post to the list, which I thought would be of interest. A company that has been in the depot repair business of DEC equipment, for the last 20 years, is about to shut down their repair lines for the DEC equipment. They obviously have prints, diags and test beds that they are going to be selling. If anyone has an interest please contact me, either on the list or privately at: pspan(a)amerytel.net Thank you for your time. Phil Spanner

CD-ROM on VAXstation 3200

by sebastian.brueckner＠epost.de

Hi! I'm trying to boot my VAXstation from CD-ROM since I don't have a tape drive. It has an Emulex UC08 controller. The internal hd and an internal MO drive are connected to the first port, to the second port I attached an external Plextor UltraPlex 32. I updated the UC08 to rom revision G143R, just to be sure and configured a cd-rom drive on the second port, scsi id 1. When I try to boot from the CD, it is ejected after a few seconds and nothing more happens. Every time i put the cd back in it is ejected again. The same happend when I tried a old SUN caddy CD drive (Sony OEM). Any hints? Regards, Sebastian ---------- This is what the machine spits out: >>>show device UQSSP Disk Controller 0 (772150) -DUA0 (RA81) -DUA1 (RA81) -DUA2 (RRD40) UQSSP Disk Controller 1 (760334) -DUB0 (RRD40) Ethernet Adapter 0 (774440) -XQA0 (08-00-2B-10-1B-D5) >>>b dub0 (BOOT/R5:0 DUB0) 2.. Here it ejects the cd and hangs forever.

Telling DECTape & LINCTape Drives Apart?

by ohh＠drizzle.com

Sooooo not too long ago there was a neato discussion of the differences between DECTape format and LINCtape format. I've got a question that's a bit different: Physically speaking, how do you tell the difference between a DECTape drive and a LINCtape drive? It's been years since I've had a chance to see either kind of drive, and since I'm doing more digging though surplus places lately I thought it'd be good to be able to spot the difference in case I actually get lucky and find one. O'course, if they're actually _marked_ "DECTape" or "LINCTape", it'd be relatively easy. :) Is it that straightforward, or is the difference more subtle (or, indeed, is the difference at the interface end and not with the drive unit at all)? (And as long as we're on the subject, does anyone still manufacture tape and reels for DEC/LINCTape users?) -O.-

Interestingly there does exist a model called a probabilistic automata that operates in just that way. In fact, if you define what accept means the right way for the model, it can be shown that there are non-Turing languages that can be accepted by a PA. Brian L. Stuart

Wavemate Bullet info/docs needed

by r_beaudry＠hotmail.com

Hello all, I recently got a bare Wavemate Bullet board, and would like to get it up and running. I received some 8" floppies with it, and they appear to be boot disks for the board. All but one was readable on another CP/M system. I'd like to get docs for it, or pointers to more information on the board. It's a Z-80 based board, and has the CPU, DART, CTC, DMA, and PIO chips. Looks like it has some RAM (16 MB8264), and some glue logic, plus a Fairchild MB8877. It is labeled "Wavemate (c) 1981 Rev. B Hawthorne, CA. Made in U.S.A." There are two 10-pin headers marked "J3" and "J4", two 50-pin headers marked "J1" and "J6", and two 34-pin headers marked "J2" and "J7". I suspect J3 and J4 are serial I/O, as the traces go to a set of 1488/1489 chips. J1 and J2 are next to each other on the right of the board, and J7 and J6 are next to each other on the top of the board. There's also another 34-pin header near the top right marked "J5". There's an 8-position DIP switch labeled "SW1". Power appears to be from a plug that loks like a typical PC-style drive power connector. I'd like to verify the pinout, though, if possible :-) Curiously, there's no EPROM, nor even a socket for one. My luck, it's some missing part :-( I'd appreciate any help! Thanks, Rich B.

power connection for 8" drive -- tandon tm848-01

by frustum＠pacbell.net

I have an 8" drive that I intend to connect to a catweasel card for the purpose of getting the bits off of a lot of old PT-DOS disks for my Sol computer archive project. If I can accomplish that, then I'll extend my Sol emulator to allow running PT-DOS on the emulator. Supposedly the floppies have a lot of interesting stuff on them, including source code to a lot of PT software. After an hour of googling, I am unable to find what power to feed it. The connector on the back is two 3-pin molex connectors and looks like this: +-------+ | X X X | +-------+ | X X | +-------+ Yes, the middle one of the lower pair is missing. I assume the power is +5, -5, +24, and GND, maybe +12 or -12 too. But guessing isn't good enough. Does anybody know for sure what power to feed each pin? I have found information on how to build a 34-pin to 50 pin cable to mate the 8" drive to the catweasel, so I think I have what I need there. Thanks for any help.

COSMAC: Can U ID this device? (Infinity UC-1800)

by tomj＠wps.com

re: Infinity UC-1800 I'm reasonably sure it's a "trainer", eg. an RCA 1802 in a box, hex keypad and switches and LED display with which to poke in "demo" toy programs. It seems to operate, inscrutably. (Here you can see I try to enter an 8080 CALL instruction to no avail) (kidding). It has an "expansion" connector available in the back. There was a leaking NiCd battery pack I clipped out and tossed, but otherwise it's complete (sans and accessories it came with). Anyone have any documentation? http://wps.com/temp/inf1.jpg and http://wps.com/temp/inf2.jpg

How many of you like HP41C calculators?

by blstuart＠bellsouth.net

While there have been other follow-ups to this thread, I'm picking this one as the point I jump in. This is a bit long and for those of you who don't see a point in this sort of "angels on the head of a pin" discussion feel free to delete. If you want to criticize me for engaging in such a discussion because there's no ROI there, then you can just kiss my big, white... :-) Sorry, too much bean counter frustration at work lately. Another way of looking at this message is that it was suggested that a professor be asked. Well, be careful what you ask for, you might get it:-) >> There are several architectures for computers, with all being the >> equal of the Turing machine. > > That's interesting, because not one of the devices I have called > computers, used as computers, or heard/seen called computers, is even > theoretically equivalent to a Turing machine. In particular, they all > have finite storage. It is indeed correct that in an absolute sense physical computers can be modeled by finite automata and don't need a Turing machine to model them. And it's correct that the reason for this is that the physical computer is finite and a Turing machine's tape is unbounded. (Almost no authors highlight the distinction between unbounded and infinite. But keep in mind that for any recursive function, the Turing machine must finish in a finite amount of time and therefore can only use a finite amount of tape. However, there is no a priori bound on that finite size.) >> Frankly, the Turing machine is the definition of a computer, > > I don't know where you got _that_, but it certainly doesn't match my > understanding, usage, or experience of others' ditto. As I remarked > above, there aren't any computers by that definition. Now here I do agree with the desire to define a computer in terms of machines that can compute functions that are computable in a Church-Turing sense. Of course in doing so we have to keep in mind that we are only looking at bounded approximations. In other words, there are some recursive functions that we can never completely implement with a finite physical computer. So if physical realizations of the computing ideal will always come up short of the models of the Turning machine or the lambda calculus, then why do we ever study these models and why do we make distinctions between recursive and recursivly enumerable? As I see it, the answer lies in the enormous size of the finite automaton that a physical computer realizes. Take even a small (by today's standards) machine with 1MB of memory. Ignoring secondary storage, the machine has 2^8388608 states. Since there are only about 2^34 nano-seconds per year, it would take 2^8388574 years to go through all the states at a rate of one new state per nano-second. Now, of course, one doesn't have to visit all of the states of a finite automaton to recognize an input string. But this observation suggests that regular languages make a poor model to describe the physical computers we build. Add to that the fact that the way that deterministic models (like RAM or deterministic TMs) handle those regular languages most naturally reognized by non-deterministic FAs is by exploding the number of states in a similar way. So the bottom line is that the regular expression model does a poor job of describing the types of interesting problems we use computers for. Now if we flip the perspective and ask about what interesting things can be done on a Turing machine, we find a similar issue. In order for the answer to do us any good, we must get it in our lifetime which implies that there is an upper bound on the size of the tape we will use in an interesting computation. Of course, this gets us right back to the same issues we have with the physical computers. Once I set an a priori bound, the set of languages recognizable is a subset of the regular languages. But once I say that, then all of the structure in the language hierarchy collapses. However, we view the question of Church- Turing computability and the questions of NP-Completeness as something more than just mental self-gratification. Therefore (you knew I had to get there eventually), the Turing machine is a powerful model to describe physical computers just as it's a powerful model to assess the limits of computation in the abstract. Furthermore, it's a more useful model than those that are actually theoretically equivalent. Those who would argue that I've shifted the discussion away >from the semi-original issue of defining a computer have a good point. Just because the Turing machine is one of the best ways to abstractly model the physical computer doesn't necessarily mean that it should define said computer. So how would I attempt to couch the definition of a physical computer in terms of a Turing machine? I'd say that if you can implement a simulation of a universal Turing machine so that the range of it's computations is limited only by the amount of addressable memory, then you have a real computer. I am aware that Cohen defines the term computer in a more abstract sense and I understand why he does so. (By the way, his is one of my favorite books on the subject.) And if I'm wearing my theoretician's hat, then I'm likely to use the terminology the same way. But when I'm wearing my engineer's hat and am appreciating the design of classic hardware and when I'm wearing my historian's hat and am trying to classify early machines, then I'm more likely to use a definition like I've suggested above. If you've stayed with me this long, you have my condolances. However, there's one more interesting point that comes out here. This sub-thread was sparked by the question of whether the potential of self-modifying code was necessary in order to be a computer. Notice that with the definition above, any computer can implement a universal Turing machine and unless you engage in some unnatural limitations, such a machine can modify it's own programming. (Remember that a universal Turing machine interprets instructions read >from the tape.) A more prosaic way of looking at this same point is that I don't need a von Neumann architecture to implement an interpreter which interprets self-modifying code. And if computing theory teaches us anything, adding or removing levels of abstraction doesn't affect the basic power of the model. My apologies for being so long-winded. Brian L. Stuart

COSMAC boards

by tomj＠wps.com

I had no idea they'd be so popular... I live in Los ANgeles, the Cosmac jobbies are in Los Alamos NM, about 1000 miles from me. However, I go there twice a year anyways, so I will buy them all, drag them home and email the list. I don't have any great interest in them, and I'll only want to recover costs. I may have taken photos of them, if so, I'll contact a local (to NM) friend and see if they can pick them up and ship, etc. Don't hold your breath, it will take a while.

Classic Computers WIKI

by rhudson＠cnonline.net

I don't know how to start a Wiki, but perhaps it would be a good thing for all of us. I would provide a "memory location" where we could all add what each knows about each kind of computer. If someone wants to host one (ie provide bandwidth and a webserver) I think the software is free.. Perhaps the classiccomp website can have a wiki branch..

DEC M750 flipchip?

by vrs＠msn.com

Does the lack of replies really mean no-one knows what an M750 "Line I/O Control" is for? Does that also mean no-one wants any :-)? I have pretty much decided that whatever they are, I am not likely to need them. Vince

IRIX setmon question

by owen＠bardstown.com

YAY! With sacrifices to the SCSI and XFS gods, I now have root on my Indy. I was told to do a setmon to improve the monitor problems -- set for better resolution + sync. Gulp... I don't see it in /usr/bin, /usr/sbin, /bin, or /sbin, and it isn't on the path. Any ideas?

AVAILABLE: HP 9000 G30

by waltje＠pdp11.nl

Hi all, One of my customers has available a complete and working HP series 9000, model G30. It includes UX media, the full manual kit (^#*($%#@()$ which is currently sitting in my living room, since they gave me the wrong set..) and, if desired, an HP series-9000 rack. The system currently is *in* that rack. The system can't be shipped, so it's pickup only. Current location is ALMERE, in The Netherlands. Interested parties please contact me off-list. No affiliation etc.. I was there to grab the VAX they were going to give me (and which turned out to be a DECsystem 5400 *yay* ;-) and I noticed that HP sitting idle there...
