Folks, Left my IIfx with both batteries out for 3 1/2 days and I still get no signs of life. I know the keyboard's OK as it powers up my IIci. Any thoughts on what else might die over a couple of years non-use? cheers -- Adrian/Witchy Owner & Webmaster, Binary Dinosaurs www.binarydinosaurs.co.uk - possibly the UK's biggest online computer museum www.snakebiteandblack.co.uk - ex-monthly gothic shenanigans :o(

request from a old post "New DEC finds"

by ddsnyder＠zoominternet.net

Ethan, You mentioned in a old post: "I have abundance of VCB02s, so if anyone wants to turn a Qbus MicroVAX into a VAXstation, I'm sure we can work something out (no mice, monitor cables or cab kits, I'm afraid)." >from Fri Jun 27 20:40:38 2003 I have a MV3800 with a 8 plane (256 color) VCB set, but I do not have the bulkhead connector or QBUS faceplate type connector nor the external keyboard, mouse and monitor cable. Do you have any of these? Please let me know, Dan

Blinkenlights for everybody -- follow-up (1)

by GOOI＠oce.nl

Hello All, I have updated the "homebrew PDP-11" page on my website and added a page called "Action!". You can download the latest software and see the Real Console in action in 4 mpeg files. So far, I have received interest to make 10 sets ... if you're not sure what you can do with these boards, here are a few more possibilities. - You can use one output port or, say 6 bits, to drive an anlogue meter via an R/2R network (simple DAC). - Same on the input side : connect a potentiometer via a DAC. - A substitute for defective logic! One example : remove the (defective) boards from the card reader (DEC aka Documation M200) and replace it with a single Core and I/O board (+ software...) - Interface a peripheral. One person was thinking of connecting an IDE drive to in/out ports and access it under program control (no DMA). - anything you wanted to give simple intelligence !!!! Updates to the hardware design are in progress, lifting the design limit of a maximum of 2 I/O Boards to the very comfortable (theoretical) 8 I/O boards. The limit is the number of octal latches that you can connect to the buffer IC -74245 in the datapath to the I/O Boards. So, there is almost no limit to drive a large console, for example the PDP-8i (over 80 lamps), the IBM S3 .... I will keep the list posted! - Henk, PA8PDP.

Digital RK05J

by vax3900＠yahoo.com

Does somebody want one? I found one in a warehouse that is used in a big digital test bench. They ask $299 for the whole bench (maybe 1000 LB) but I can ask them whether I can pull the RK05j and buy that only. I ask $10 handling fee only.

Bad Tapes. 1 bit of info...

by aek＠spies.com

There was a report on a NYC audiotape archive just now. Mentioned was a common problem of tape flaking and one last ditch solution was to bake the tape in a convection oven for 24 hours, presumably to re-seat the oxide into the plastic. Sounds like the temperature has to be exactly right. == Google "Sticky Shed Syndrome" Common problem with hydroscopic decomposition of the tape binder. A temporary solution is to dry the tape out by baking.

Hi there, I have a Mac LC-II (with monitor), an SE-30, and every issue of MacWorld/MacUser from the first issue through about 2002 sitting in my basement in the Denver metro area. I'm offering the computers to anybody who wants them Ffor the price of shipping, if you want them sent) and whatever you think they're worth. First come, first served... As for the magazines, I tried to donate them to our library, but they say they don't want them. If you want them AND can come pick them up (believe me, you to NOT want to pay shipping costs!), they're yours. Send me a message directly (not via this list) by Friday, 4/30/04.

Mac IIfx update

by cb＠mythtech.net

>No jerk, but I've already swapped the PSU with one from another Mac II and >got similar results, though I guess it's entirely possible that one's toast >as well. Nothing obviously physically wrong with the PSU though, no bulging >caps etc. Was there a common cause of death for them? It would seem odd that two supplies would be dead. Another thought. Is the ROM simm installed? The IIfx requires it. IIRC, when I had someone pull the ROM simm from a IIsi, the machine failed to power on without the simm installed. So maybe the ROM simm is missing. Also, if the simm is in place, there may be a jumper to tell the Mac to look for the simm. Look for a jumper marked W1. If it is on, the Mac will NOT look for a simm, if it is off, the mac WILL look for a simm. The IIfx requires a ROM simm, so the jumper should be off and the simm installed. (the jumper info is as per the macfaq.org web site, I've no personal experience with the jumper issue, and I don't know if the person that tested the IIsi for me knew about the jumper or not). >That's helpful of them :) Its a 2.7 MB PDF, I'd be happy to send it over to you so you can see for yourself just how UN-helpful the thing is (some of the tech manuals are great, others leave much to be desired) :-) -chris <http://www.mythtech.net>

Time article about Jobs

by aek＠spies.com

I wasn't sure when they met, but I did seem to recall that Jobs did get Woz the Atari job. Wasn't that where Jobs was working, and they wanted to design a handheld game, and Jobs got Woz to do it, and he did it so well, Atari couldn't figure out exactly how he did it. -- Woz never worked for Atari. He built the first prototype for the game that became Breakout. At the time, Bushnell would pay a bonus based on how few chips you could use for building a game. Woz used HP custom ICs, which were unavalable to the outside world to do it, so it had to be redesigned to take them out to get the game into production. Jobs was the Atari tech on the project (and was the one that got the bonus, which he never told Woz about..) This info was told to me by the VP of Engineering of Atari at the time this all happened.

Looking for Interand 3000 (a.k.a. Interand CT-2)

by vcf＠siconic.com

Ok, now I'm looking for a manual (or actual hardware) for the Interand 3000, which was sold in the Japanese market as the Interand CT-2. The full product name is the Interand 3000 Multi-Point Imaging Worksystem. It allowed full color video-conferencing over a digital or two analog phone lines and had features that enabled conference participants to create and edit documents collaboratively, draw on the screen (allowing the same image to be seen on both sides) and other nifty features. It's similar to the Telestrator that John Madden "invented" (from what I know the Telestrator was based on the Interand 3000). This is related to the Koby Electronics HS300-01 power supply that I'm trying to locate. Anyone have any clues? Are there any museums around that might have one? These are old enough and significant enough that they should qualify. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]

Making the decision to specialize on a particular classic comp. arch?

by dzubint＠vcn.bc.ca

I'm wondering if anyone else has this problem. For years and years, I've basically collected anything non-Wintel old-ish (older than ten years) computer-related stuff. I've got quite a few systems which aren't really "rare" like Commodore 64, Radio Shack Cocos & MC-10s, TI-99s, etc. etc. I've also been amassing a collection of DEC PDP and VAX "stuff" which I work on, use, and enjoy on a regular basis. My basement is a mess and I'm starting to think about scaling back by selling or giving away some of the non-DEC common stuff. (I regularily see Commodore 64s on eBay for $20) Is this specializing the right approach? Am I likely going to be kicking myself in fifteen years because I *had* a working Radio Shaft Colour Computer and I eBay-ed it for $10? Also in my mind is the possible demise of analog TV and it may not be possible to find a TV with a composite-input to plug my C64 into in fifteen years if everything (including broadcast) is digital Any thoughts, comments, or opinions?

IBM serial number query

by vcf＠siconic.com

Someone contacted me and said they have an IBM PC that he was told was the 35th off the assembly line. The serial number he gave me off the unit is 0205544. He also gave me a number he found inside the chassic which is IBM1800841. He said the motherboard has been upgraded to 64K. I don't know if he meant it was upgraded to the 64-256K motherboard or if the RAM sockets on the original 16-64K motherboard were populated. Can anyone shed any light on the serial number(s)?

HP Viper problems

by rigdonj＠cfl.rr.com

Does anyone here have any experience with the HP Viper or HyperViper cards? Now that I have a working HyperViper system I've been pulling out all the Viper and HyperViper cards that I've has stashed away and testing them. I found the the software on the working system works fine with the 82321C Viper cards but not with the 82321B Viper cards. The device loader and BASIC loader both work fine and they start what looks like a HP 9000 type boot sequence that shows all the installed devices and does a memory test. After that completes it SHOULD looks for a HP system file and boot HP BASIC. The C cards work fine but the B cards never find the system. Everything is EXACTLY indentical except the card revision. I'm using the last version of the drivers and according to HP they should work for all versions of the card but I've checked two HyperVipers and two C cards and they all work and yet none of the four B cards work. FWIW I have another system with an older version of the software. It used to work but the hard drive in it has been slowly dying and now it won't can find the system either. It has a B card in it and I think version C software. The odd thing is that it looks exactly like a 9816 or 9836 booting up. It even displays a message saying that it's a 9816 or 9836C (depending on which you select with the configuration utility). The later system says that it's a PC 300 and the boot screen is somewhat different. I think the difference in due to the newer software but I'm not sure. I need to pull the card from the old system and try it in the newer one to be sure. (There is a Boot ROM on the cards and in a real HP 9000 it controls those messages but I don't think that's the case on these.) I tracked down a new sealed package of the Viper software but wouldn't you know it, it's missing disk 2!!!! Does anyone have any original software for these or any experience is getting them running? I'm also looking for some of the key combinations that HP uses to emulate the HP keyboard for thing like the Stop and Reset keys and how to get back to the User keyboard from the system keyboard.

New find; HP HyperViper

by rigdonj＠cfl.rr.com

Hello Bernd, I'm still experimenting with the Viper system. The HyperViper is a real pleasure to use! Today I hooked up a couple of different external HP-IB hard drives and tested them. Two of them were untested and it turned out that both were bad :-( The third one is an old reliable standby HP7958B with HPL, three different configurations of HP BASIC 4, BASIC 5 and BASIC 6 installed on it. At first I couldn't see the drive when the HV started looking for operating systems but I was able to CATalog the drive after it booted the Rocky Mountain BASIC from the PC's hard drive. It took me a while to figure out why I couldn't see the external drive when the HV booted. I finally realized that it was booting so fast that I never saw the list of OSs on the external drive! The funny thing is that it showed the OS of the PC drive for several seconds before it booted but it booted IMMEDIATELY after showing the OSs on the HP-IB drive. I found that I had to press the space bar on the keyboard as soon as the Boot ROM kicked in and started showing system devices. Pressing the space bar stops it from booting after it shows the OSs. At that point you can boot any OS that you choose (same as any HP 9000 200/300). Anyway I was able to do a SYSTEM STORE of the RMB to the HP-IB drive and then boot it from that drive. It appears to work exactly the same as the copy loaded from the PC's hard drive. I could also boot BASIC 4 and BASIC 5 but the display was shrunken vertically on all of them. One configuration of BASIC 4 worked ok but the others of BASIC 4 and BASIC 5 all filled the blank areas of the screen with various characters when you did a CAT. However they all did seem to run. BASIC 6 was the real surprise. It definetly didn't like it! As soon as it started to load, the machine would jump back to DOS. Under normal conditions you CAN jump back to DOS but you should be able to go right back to RMB and your OS and application will still be running as if nothing happened. But in this case, you couldn't go back to RMB until you powered down the system and powered it up again and rerun the device driver and loader. The loader said that RMB was still running but you never could access it again. HPL was just as bad, when I tried to load it the screen cleared and the machine appeared to lock up. I couldn't switch back to DOS and Control-Alt-Delete didn't have any effect. IIRC HPL has a similar effect on the HP 9000 300s. HPL is only supposed to run on the 9826 and 9836. I think it will work on a 9816 but I don't think it will even run on the other 9000 200s such as the 217 and 237. I haven't tried Pascal yet. I have it on a drive but it's on another system and it will be a pain to get to. But I'll probably dig it out tomorrow and try it. I found a long list of optional parameters in the loader program (BASIC) including things like SELFTEST, MENU, SHORT, LONG and others but none of them appears to do anything. Anybody know anything about them? Joe At 06:10 PM 4/22/04 +0200, you wrote: >Hi Joe, >does it run a version of HP Pascal too ? I'm not sure but I believe it will. I think I remember reading that it will boot an OS from an external HP-IB drive just like a regular 9000/200 will. I need to dig out a drive and try it.

More digging later has revealed three Usenet articles from the same week in 1997 of a product called the "BASICON MC-1N REV A" - there's no vendor name on my INS8073 board, but the part number matches. The Basicon, Inc. website says they are the victim of the current economic times. I've written the repair service listed on their page, but we'll see if they answer. In the meantime, has anyone heard of Basicon? Might their "MC-1N" be the same as what I have (INS8073, 2K SRAM, 8255...)? I've figured out most of the circuit - what has me stumped is that the chip selects are all run through a 74S188 burned as an adress PROM (its address lines are attached to A15-A11 of the CPU, and its data lines go to various chip selects on the board). I've tried building a circuit to manually dump the PROM (it's only 32x8), but no success there - all the bits read '0', which means "always selected" for all devices... clearly not correct. Once I figure out where in memory the MM58174A and 8255 are, I can do more than enter simple BASIC programs. I'd like to see if there's room in the memory map to add more SRAM - there's stuff I'd like to port from my collection of PET programs that would need more than 2K (especially since the 8073 doesn't appear to tokenize its BASIC code when it stores it in RAM or ROM). I've tried writing a program to read every Nth location between the top of RAM and the top of memory space (the RAM, I've already proven, is at the standard address of $1000)... because of the way the INS8073 determines its baud rate (110 bps in this case :-P), "empty" locations read back "182" - no matter where I look, though, I can't get any locations outside of RAM space to answer back with anything else. I'd love to get a manual for this, but there just doesn't seem to be that much information on the 'net about it (if I _have_ that particular product). I'm hoping that it is one of these... it's a pretty neat board... 24 I/O lines out the front, 2K of SRAM and either 2K or 4K (2716 or 2732) of ROM and a clock/calendar. There's even optional battery-backup for the clock chip and the SRAM (just add 3V-5V to a particular pin on the serial/power connector). Thanks for any leads. -ethan -- Ethan Dicks, A-130-S Current South Pole Weather at 25-Apr-2004 10:10 Z South Pole Station PSC 468 Box 400 Temp -60.3 F (-51.3 C) Windchill -114 F (-81.09 C) APO AP 96598 Wind 13.3 kts Grid 004 Barometer 685.5 mb (10420. ft) Ethan.Dicks(a)amanda.spole.gov http://penguincentral.com/penguincentral.html

Mine > is dead, so i never got my machine up and running :-( The machine I've looked at so far has a good PSU, but the track on the power distribution board that feeds +12V to the system board is totally burned away, and someone had bypassed it with a piece of wire. Obviously the system board has suffered some major short at some point - I'm yet to find out if the bypass wire was added after they fixed the fault or not! In other words, it's possible one system board is completely dead, in which case yes there could well be a spare PSU. Depends on what state the system board is in this machine, and whether the PSU in the other one works or not; idealy getting two machines working would be nice! You could always use a standard PC PSU I expect. There's six different lines running to the PSU in these Whitechapels; GND, +5V, +12V, power fail are four of them. The purple wire I expect is -12V. That leaves a red wire, which would seem a strange colour to choose for a negative voltage. Maybe it's +15V or something odd, perhaps for driving the display. I'll let you know when I work it out :-) cheers Jules

Whitechapel MG-1 workstation questions

by julesrichardsonuk＠yahoo.co.uk

A few initial questions after a couple of these beasties turned up at the museum: Does anyone have OS install media for these? We've got the manuals, but no floppies and I'm not sure what state the hard drives are in yet. Don't suppose anybody has schematics / service information? Predictably, the batteries inside the machines are toast and have taken half the circuitry with them (grr!). I'll clean everything up and then bypass the tracks which have been damaged / eaten away. Presumably there's a trick to starting these things after battery failure by feeding power straight to the internal relay - any ideas what voltage it needs though? And once running will I still need to keep the relay energised or will the PSU circuitry take over (even in the absence of batteries - I'm just going to remove the damn things completely)? I've got one hard drive to spin up and become ready after dumping half a can of WD40 onto the bottom spindle bearing - it wouldn't even turn before that. Now it just sounds like a sick cat. :-/ Hopefully it'll last long enough to get any useful data off it though. I notice what seems to be a SCSI connector on the system board - can I pull out the ST506 disks and just run a more modern (and hence reliable) SCSI disk from here? Or is the SCSI connector (if that's what it even is!) just designed to support a tape drive, and the machine always expects the boot drive to be an ST506 disk? cheers Jules

VAX Architecture (was KA620)

Hmm, did they seek process page tables in physical or in system virtual memory? If the latter, I don't see how can they be called rtVAX, as that by definition means the former. If the former, how can you do that with a standard VAX chip? Or does CVAX have an undocumented hack pin which when tied opposite to what general specs say causes it to seek process page tables in physical memory? > There's not a huge difference between STD 032 and the books. > There are a few paragraphs missing here and there but I don't > remember anything hugely significant [...] > [...] > [bug lists that were cut] But even these would not help you understand the > architecture any better. OK, I've already figured myself that all the really important "what is a VAX by definition and how to build one" stuff *is* in the published VARMs, so my project of building a new VAX is not stuck waiting for KGB to pry STD 032 out of DEC. I fully understand the VAX Architecture (and have a solid rigorous spec definition) based on the 3 VARMs I have (Rev 6.1, 1st ed. and 2nd ed.) and I should have something exciting on the new VAX front hopefully not too long >from now. It would still be nice to seize and free the full DEC STD 032 for completeness, but this task can be left until later when we can raise a large enough army (using human cloning, genetic eng. and neurolinguistic programming to make perfect killing-machine soldiers) to invade and overrun USA including ex-DEC facilities and archives. > The only major omission is the Virtual VAX stuff (which was > done for some three letter agency but never became a product > - I heard that it just ran way too slowly to be useful). > It has its own SID (09 IIRC, I guess(0)07 was already taken :-)). Ahh, thanks for explaining that! One fewer mystery. I have known about VVAX >from the Ultrix sources (which are on my FTP site), but I didn't know what it was. Now I know. :-) Actually Ultrix was made to run on it too according to comments in the source, though the actual VVAX-specific machine-dependent code is not present in the source tree I have, it just has SID and misc. definitions for it, pointers to VVAX code in the CPU type dispatch table (conditionalised on #ifdef VVAX), and comments mentioning it. And yes, the SID code is 0x09. Now that I know that VVAX was real (and not an Ultrix internal thing - Ultrix does have some fake SID codes of its own that do not correspond to anything in hardware), I now know what's in the gap between 78032 and CVAX SID codes. :-) So they were upset at MicroVAX I for taking 007, huh? So this only leaves SID codes 0x0C, 0x0D and 0x0F as unexplained gaps. I suppose that perhaps 0x0F could have been truly skipped after 78R32 jumped to 0x10 (I guess 78032/78R32 liked power of 2 SIDs), but I can't explain how has VAX 9000 got 0x0E unless 0x0C and 0x0D were reserved for something (that apparently never saw the light of day). Any idea what 0x0C and 0x0D were reserved for? Also what SID codes were assigned past 0x14 in the VAX's dying gasp? NVAX+ (NVAX in Alpha 21064-mimicking pinout) was given 0x17, wasn't it? And what about NVAX5 (NVAX in EV5-mimicking pinout)? Was it also 0x17 or was it 0x18? And then I've heard rumours about there being a never-released NVAX6... And why were 0x15 and 0x16 skipped? One reason it's important to understand the complete history of SID code assignments is that if we start building new VAXen, we'll need a new SID code registry. I plan on calling it DANA, for DEC Assigned Number Authority, in emulation of IANA (Internet Assigned Number Authority). But to make it proper, the new registry will have to start assigning codes exactly where the old one left off. And DANA won't be just for SID codes - there are also VAXBI device types and all sorts of ID codes used in MSCP/SCA, etc. > I think I've said before, what you really want is not STD 032 > but AXE, the tool that runs on your new VAX and checks for > correct operation of instructions. I've never heard about AXE from you, but I have heard about it from other sources. Yes, that would really be nice. Interestingly, however, it appears that at some point there were diagnostic programs available to the general public that, judging from the descriptions, apparently do similar instruction testing, though they were presumably intended for troubleshooting broken hardware rather than for validating new implementations. The KA820 Technical Manual, for example, refers to these: Table 7-2: Program Code Program Name Run-time Environment Hardware Tested EVKAA VAX-generic Level 4 (stand-alone, VAX instruction set cluster boot and run from the used by VDS exerciser: console) hardcore instruction test EVKAB VAX-generic Level 2 (on-line or Basic VAX instruction cluster stand-alone) set, nonprivileged exerciser: basic instruction exerciser EVKAC VAX-generic Level 2 (on-line or Floating-point VAX cluster stand-alone) instruction set, non- exerciser: privileged floating-point instruction exerciser EVKAE VAX-generic Level 3 (stand-alone) Privileged VAX cluster instruction set exerciser: privileged architecture exercise [descriptions of KA820-specific diags omitted] The descriptions of these diagnostics sound very much like AXE. Any idea where to find these diags? MS

Computer History book in Arabic

by vcf＠siconic.com

I just learned that a new book on computer and internet history has been published that is written in Arabic. The author, Richard Hayek (based in Lebanon), is an IT journalist for an Abu Dhabi based newspaper. It is the first book (that is known) written in Arabic on the topic. I'm in contact with the author and am in the process of ordering several copies. As far as I know, the only way to get the book here in the States (or anywhere outside the Middle East) is by ordering it through him. If anyone else is by chance interested in a copy then let me know and I'll order you a copy as well. They are US$8.25 each plus postage. This of course has personal interest for me but I think it also indicates how that part of the world is finally joining the computer revolution. Computer and Internet penetration has taken a long time for most Middle East nations, but some have adapted faster than others. Lebanon, for instance, has some of the highest penetration of the Internet, with Internet cages everywhere. I would imagine other more affluent nations such as the United Arab Emirates and Bahrain probably have a higher per capita penetration of personal computers but I don't know what the controls over the Internet are. Many Middle East nations have internet access of some kind though it is heavily censored usually. Anyway, kinda neat. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]

I think the NeXT Optical drives were intended to provide a functionality like this. Carry your own OD media around, stuff it into the NeXT you sit down at, and your entire (256Mbyte) environment is right there with you. (I'm not sure I have a reference to support this, though. Maybe NeXT sales materials? Anyone else?) Performance didn't live up to the rapidly moving HD performance of the day, and the idea got overtaken by network via ethernet. Sit down, telnet into your machine back home. That makes me think that the idea will only work where 1) the portable medium has pretty good performance (speed-wise) relative to current primary mass storage, and 2) The OS/environment startup process is relatively short (say, maybe, < 20 seconds?) -- - Mark 210-522-6025, page 888-733-0967

Selectric Terminal

by pat＠computer-refuge.org

So, I decided "what the hell" and got one of these: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=3810203578 The auction calls it a Selectric model 731, and it's got a 55 pin round "Mil Spec"-style connector on it. Does anyone know anything about these? The only reference I've found via Google is to using this model of Selectric on a PDP-6.

Blinkenlights (not only for PDP-11) -- the sequel

by GOOI＠oce.nl

Hello all! I have been busy interfacing the "real console" to SIMH last week. During last week Vince has drawn some Printed Circuit Boards (PCBs). Vince and I had frequent e-mail contact working through the designs. Basically, this e-mail is an inquiry to which extend people would like to embark on this project. So, let me know if you would like to participate in this project!! But before you put the $$ on the table I will try to explain in more detail what the status of my project is and what use it can have ... In this e-mail I address the following topics: 1. Some ideas where this project can be used. 2. A small description of the hardware. 3. An introduction to the firmware. 4. The interfacing to SIMH, state of affairs. 5. An estimate on the building costs. 6. What the project participants can expect. Allthough my primary design goal was a "blinkenlight" console based on the PDP-11 and a PC running SIMH, the hardware is multi-functional with the large amount of digital inputs and outputs. You can think of several other applications to control with this harware, for example a robot arm with some stepper motors ... just use your imagination! During this weekend I will update my website with a few .mpg files to show you a console in operation with SIMH, and a few samples of the console running in stand-alone mode. So, check next Monday the site http://www.pdp-11.nl/ and click on the link "homebrew PDP-11" in the left pane. The latest software version will also be downloadable. ** 1 ** Ideas for use. First, let me say that I do NOT support the idea of trashing a nicely working real PDP-11 computer to get a console! If you have a real PDP-11 console, this project will allow you to use the computer that runs SIMH (PC) to be controlled with the PDP-11 console as the real thing! This hardware is an other option for people that do not have a real PDP-11 with blinkenlight console or do not have the space for such a big (UNIBUS) machine. A third option for usage of this hardware is for people that *have* a real PDP-11, but running that system is noticed on the electrical bill! One could build a PC inside the real PDP-11, and disconnect the flat cables from the real console and connect them to this hardware. Running the PC/SIMH with the real console looks like the REAL THING but without the big energy consumption. Of course, the real disks and other peripherals are all "inside" the PC ... This setup might be a solution for a museum. The system is exhibited in a running state, and the changes made can simply be reverted to the original state. The fourth usage is for other computers that have a blinkenlight console, and are emulated by SIMH. The PDP-11 file in SIMH shows how to interface your favorite machine. You can run your favorite vintage computer in SIMH with that sexy switches and light console! ** 2 ** The hardware. We have two different design approaches. The first is called the "combi-board". The combi-board is a single PCB which contains the CPU etc. and *eight* 8-bit output ports and *six* 8-bit input ports. This in/out configuration can support the largest PDP-11 console, viz. PDP-11/70 full console! The second design consists of *two* PCBs, one is called the Core Board, the other the I/O Board. The Core board holds the CPU, etc. and the I/O Board offers also 8 8-bit output and 6 8-bit input. The combi-board is a little cheaper, but the two-PCB design offers expandability if you need more outputs/inputs. (who said this hardware design is for console interfacing only ?!) The design efforts of Vince and I are focussed on the 2 PCB version. Note. If you checked my website and had a look at the schematic diagrams, I must tell you that there are a few minor changes. For example, the expensive Dallas RS-232 converter chip is replaced by the cheaper MAXIM MAX232A chip. Further the 8kbytes firmware EPROM 2764 was full up till the last 500 bytes, so there was little room for any future development. The address decoder LS138 is substituted by one 74LS139 thus enabling the change from the 2764 to one 27128 16 kbytes EPROM. That also eliminates the need for an optional 2nd 2764 EPROM socket, which saves space on the PCB. ** 3 ** The firmware. The firmware contains in approx. 8 kbytes a simple debugging monitor and the console software. Which software (monitor or console) starts is determined by a push-button at reset. Both talk to a terminal via the RS-232 port at 9600 Bd. In the console mode, the RS-232 connects to the interface software added to SIMH to control the console from SIMH. It is completely free to which input port and bit(s) you connect the switches and the (momentary) toggles. Via the firmware you 'learn' the console where the switches/toggles are connected. The firmware handles the appropriate way of processing toggles and debouncing. ** 4 ** Interfacing to SIMH. I added two extra files (one .c and .h), and made simple changes and additions to the files scp.c and pdp11_cpu.c of the SIMH software. Current state of affairs: ADDRESS and DATA LEDs are functional, also the USER, VIRTUAL, CONS, and RUN LEDs. I have not yet spend time to find a way to implement the control from SIMH for the BUS & PROC LED. The toggles LOAD ADRS, EXAM, CONT, START, and DEP work as you would expect on a real PDP-11/40 (aka PDP-11/35 OEM version). The ENAB/HALT switch is operational too, HALTs the emulated software when it runs, and changes CONT and START to STEP and RESET while in the halted state, the switch in the position HALT. While STEPping the software the ADDRESS & DATA LEDs are correctly updated after every single instruction execution. ** 5 ** The costs of the project. First, I need to know how many people would like to participate in this project. The more people join, the cheaper the production costs of professionally made PCBs become. The (single) combi-board will be somewhere around $40 to $50, and the two PCB design (Core and I/O) will be slightly more expensive, the 2 boards will cost approx $10 more than the combi-board. This solution provides expandability for hobbyists, or use in other projects. The required components to populate the PCB(s) can be seen in the diagrams on my website. You can make an approximate calculation what these components cost. Probably prices are lower in the USA compared to The Netherlands where I live ... ** 6 ** What will you get if you join the project? I will write a clear, well documented manual that describes the PCBs, the protocol, and a step-by-step DIY building the PCB(s) with clear *full color* pictures. The firmware and the modified SIMH files can be downloaded from my website. However, I will offer a pre-programmed 27128 for just the cost of the IC (here in The Netherlands). You can also snail-mail me an *empty* 27128, and I will program that one for you, but I doubt if that option would be cheaper ... REMARK. If you would like to participate in this project, but are not sure to successfully solder the PCB(s), I will offer a (payed) service that delivers a working/tested PCB (or two PCBs). The modifications required in SIMH are done for version 3.2.0. The first work was done on version 2.4.0, and I found a few changes were needed, as scp.c was changed. However, when a new version of SIMH is available I will put the required changes on my website within, say two weeks. So, unless SIMH changes drastically, continuity will be guaranteed on short notice, else I will need a little more time! If you join the project for the hardware, but do not intend to use it for a console, but in some other project, you can ask me questions too. I will give answers to the best I can as long as they involve the design, or the software. I have good knowledge of MC6802 assembly programming. Please feel free to write an e-mail to me if you have any questions! I will try to answer all questions in private e-mail, next week. If the question is general I will post a follow-up in this thread. regards, - Henk, PA8PDP.

Nearly on topic-ish. Digital HiNote VP laptop

by witchy＠binarydinosaurs.co.uk

Folks, Discovered I had said old machine in storage the other day and I thought it'd make a neat little webserver for when I'm away from home working and will have nothing better to do than PHP hacking. First time I powered up it sprang to life but locked up because the CMOS battery (non-standard dammit) is obviously flat. Subsequent powerups with or without battery installed (you can replace the floppy drive with a dedicated AC input) result in a beep and pretty much nothing else. Anyone come across these wee beasties before? Aside from when they were new, obviously :o) cheers -- Adrian/Witchy Owner & Webmaster, Binary Dinosaurs www.binarydinosaurs.co.uk - possibly the UK's biggest online computer museum www.snakebiteandblack.co.uk - ex-monthly gothic shenanigans :o(

Time article about Jobs

by cb＠mythtech.net

>Jobs met Wozniak when he was still in high school (introduced to each >other by Bill Fernandez). Wasn't it Jobs who got the job for Woz at >Atari? I wasn't sure when they met, but I did seem to recall that Jobs did get Woz the Atari job. Wasn't that where Jobs was working, and they wanted to design a handheld game, and Jobs got Woz to do it, and he did it so well, Atari couldn't figure out exactly how he did it. Or am I mixing up another incident (or possibly even an urban legend) -chris <http://www.mythtech.net>

Hello, I have an Otrona with 5 1/4" disk drives. Problem is that I don't have the boot disks for the machine. I wondered if you send me a copy if you still have them. What would you charge for them? I would appreciate any help you could provide. Thank you, Don Radford, Cincinnati, Ohio

From alt.sys.pdp11 -- PDP-11's in SoCal need rescue from scrapper!

by wmaddox＠pacbell.net

I saw the following posted on alt.sys.pdp11: [from Jeff Davis <jdavisgoogle(a)soupwizard.com>] Hi, I frequent the University of California - Santa Barbara surplus store and noticed they have the following PDP stuff that is heading for the scrap heap this week unless someone comes and buys it (and considering that the alternative is scrap prices, it'll probably go cheap): (from memory, so it's probably 85% accurate): - 4 waist-high 19" racks containing the PDP stuff. - 2 each PDP-11/23 rackmounted - 2 each PDP-11/73 rackmounted - at least 4 RL02 drives - a couple or more RC25 (I think) cartridge drives - other random equipment that I can't identify - 2 Decwriter line printers/consoles - A big push cart full of (looks like unused) RL02 packs and RC25 carts. - RSX manuals and a bunch of other documents All this stuff came from an installation that was finally turned off, so it looks complete. I'd get it for myself, but I just do not have room. If you're in the Santa Barbara / Los Angeles area and are going to pick this stuff up and need a hand, let me know.

CUDA Switch

by alhartman＠yahoo.com

"CUDA" doesn't mean anything by itself. It's not an Acronym. It is a shortening of "Barracuda". The main chip in the Mac that controls the Clock/Calendar, PRAM, and some of the I/O is called the Barracuda chip. It was a question on my Apple Certified Technician Test. - Al __________________________________ Do you Yahoo!? Yahoo!

I've heard John Oliger's stuff is quite good. A friend had his TS-1000 all tricked out with a John Oliger Disk Interface, Parallel Port, Color Graphics Interface, Joystick Interface and more...

Time article about Jobs

by aek＠spies.com

> My recollection may be off, but this is straight from Woz, Al. Woz is a nice guy, but after his plane crash / amnesia there is a lot that he doesn't remember. The story came from Al Alcorn who had to fix the unshippable mess that Woz created. I had wondered about the story about a year ago, while Al and I were going through some of the old Atari documentation that he still has, and I made a point of asking him EXACTLY why they couldn't ship what Woz had built. The specific part of the circuit is the on screen score circuit. There is a fairly complicated glob of gates there around a seven segment decoder IC which HP had reduced to a single IC. Woz had used that part in the proto that he built. Atari had to replace it with conventional logic. They knew EXACTLY what he had built, they just couldn't put it into production using the parts they could buy.

They are testing Williams, Desmet, Lattice, Computer Innovations and Digital Research tools. The artical is fairly long - about 13 pages. If this is of interest to you, I could scan it and put it somewhere where you can get it. Btw, this particular issue (Aug 83) is entitled "The C Language", and has a lot of good material in it: Theres also a comparison of 5 CPM/80 compilers which also uses the Sieve as one of the main benchmarks, There's alse a comparison of 9 PC/DOS compilers, but I don't think (from cursory re-read) that they use the Sieve in that one. On top of that, there's an artical by Steve Johnston and Brian Kernighan describing a lot of the design philosophy and early experiences, a couple of general "into to C" type articals, and artical on C in unix systems, A C bibliography, an artical on C compatibility issues between Unix and CP/M and a bunch more - really a good issue (which is why it's one of the few I've kept). Don't think I want to scan the whole thing (unless you want to wait a *LONG* time) - but I will do what I can to get any parts you are interested in to you.

I wonder what Jef Raskin would make of > that comment. Though it is true that Jef Raskin started the Macintosh project at Apple in 1979, his Macintosh was to be an 8-bit utilitarian machine. It would have had a bit-mapped screen, but no GUI or a mouse at all. Jef Raskin has always been very devout in user interface which promotes keeping your hands on the keyboard. His 1987 Canon Cat is more along the lines of what Raskin's Mac would have been. Raskin simply gave Jobs an easy existing platform "vehicle" to take over, when Jobs was denied control of the much touted Lisa project. Raskin left Apple in 1982 after Jobs took over (but I think he still signed the Mac inside case - anyone?). Jobs wanted to out "Lisa" the Lisa project, and so the Macintosh quickly went from a $500 consumer computer, to $1000, to $1500 and finally to $1995 - that is before Sculley thought it should be $2500 minimally (thus was born Apple's outrageous profit margin on Macs). Jobs certainly does deserve a huge amount of credit, however wrong he might have treated anyone, for his pure force of will in the creation of the Mac as we knew/know. He forced some design decisions which were wrong and Apple paid for (closed architecture, etc.), but he was 90% on overall (appliance design, one button mouse). His direction with Apple in the last 6 years has been mostly very good. Apple's stock is steadily rising now. The Mac consumer market remains at about 6% in the US, but their server (OS X) market is growing big-time. The Mac OS is excellent. I still love to set up my cube and run NeXTSTEP 3.3, which I now understand a lot better. Here are some recent opinions of Jef Raskin's about the Mac: http://www.macminute.com/2004/02/11/jeffraskin Best, David, classiccomputing.com

TI Bubble Memory?

by yakowenk＠yahoo.com

Just some useless info, FWIW. All this recent talk of bubble memories got me to remembering.... A company I worked for in Buffalo NY around 1982 was putting bubble memories into a small diskless machine that they sold (or rented?) to golf-course pro shops. It was called a "handicaputer" - it kept track of golfer's scores and handicaps and such. No idea how many were made, but my impression is not very many. But it might be something to watch for, for anyone into bubbles. We also had, IIRC, an SS-30 card (SWTPC I/O bus) with a bubble memory on it, for which I hacked Flex "disk" drivers. (Somebody else had already written the lower-level bubble read/write code.) At one point it booted into Flex. Might have been called "disk-bub" or "flex-bub" or something similar. Sold only a handful though. Really cool but probably too expensive unless you really needed bubbles for some reason. One went to some research station in Alaska (or Antarctica?) - they said disk drives would have frozen up. Bill. __________________________________ Do you Yahoo!? Yahoo!

EC-1

by effectivehcps＠bellsouth.net

Dwight, I ran across your posting about the EC-1. I am afraid I go back to the EC-1 period and used hybrid analog-very early digital computers at North American in the early 60s. I wondered if you knew of a source for a fairly good condition EC-1? I just purchased one and am in the process of getting it to work again. But would like to have a second unit to share parts with, etc. Hope this gets to you. Thanks. Larry Royster.

Byte Sieve of Eratosthenes Results?

by mtapley＠swri.edu

All, A question: I wondered if results from the Byte Sieve of Eratosthenes "benchmark" are publicly available anywhere, or if I have to root out a copy of Byte Magazine? I googled for it, and found nice C and Forth versions at http://home.iae.nl/users/mhx/nsieve.html and *some* results, but I'd sort of like to re-read the original article and see what the results for all of the classic computers they tested were. The above URL cites Byte, Sept. 1981, pp. 180, and Jan. 1983, pp. 283. Copyright law being what it is, I assume the articles are still Byte magazine IP, but I'd think they could gain a fair amount of publicity from having that article posted somewhere as a "teaser", particularly if they link to some of the url's showing modern machine performance. Can't find such a pointer on their site, http://www.byte.com however. And the site itself is not encouraging. -- - Mark 210-522-6025, page 888-733-0967

New find; HP HyperViper

by rigdonj＠cfl.rr.com

Today I finally had a chance to check out a PC that I found a few weeks ago. I had picked it up becuase it had an HP-IB connector on one of the expansion cards. When I looked closer I saw that the card had a sticker marked "HP 82324". Bingo! That's the part number of the souped-up Measurement Coprocessor card that's commonly called a HyperViper! I have a number of Viper cards with 68000 CPUs but I'd never even seen a HyperViper card. The HyperViper uses a 16MHz 68030 CPU. The Vipers and HyperVipers are HP 9000 series 200 or series 300 computers on a board. You install them in a PC and run a driver and it switches over to the 680xx CPU and runs (almost!) exactly like HP 9000 computer. It has a built-in HP-IB port and supports additional HP-IB cards. It also mounts a HP 9000 file system in one file on the PCs hard drive. It uses the PC's parallel and serial ports and uses the PC's keybaord and monitor for user I/O. Anyway today I opened it up and cleaned all the dirt and insects out and fired it up. It booted to DOS then loaded the HP software then switched over to the HyperViper card and booted HP BASIC version 6.2 (Rocky Mountain BASIC) without a hitch. Wahoo! I'm in business now! It even has the last version (D.00.00) of the HP divers. HP's Viper and HyperViper site >> <http://ftp.agilent.com/pub/mpusup/pc/old/vp_over.html#m5> Joe

Selectric Terminal

by brian＠quarterbyte.com

I have one of the these too. They were standard IBM IO Selectrics, modified electrically for what appears to be use on a military aircraft. I'm planning on building a serial or USB interface for it so I can use it as a remote terminal for my IBM 1130 simulator. I've gathered a lot of information about it including the connector, signals etc. If you're interested, let me know and I'll send you what I have. These machines being sold on eBay, by the way, are in wonderful shape mechanically but most likely have a shorted or open control soleloid. Brian

Got that INS8073 SBC to respond!

by dickset＠amanda.spole.gov

Thanks to all who sent me copies of that MM58174A app note. I'm not quite to the stage of using the contents, but it's nice to have. I do have scans of the board that I intend to put up on my website, in the meantime, I have been tracing the board and have puzzled out the 10 pin connector - it's power, gnd, battery-backup for the 6114 and MM58174A, serial in/out, and three of the I/O bits (SB, F2, F3) on the CPU. I have raided the local electronics scrap bin (we have to sort our waste into numerous categories from "burnables" to "food waste" to "light metal", etc., including "electronic scrap") for the connector off of a dead CD-R drive, mounted the power connector and the audio/master-slave connector to a piece of perfboard, and constructed a daughter card that gives me easy-to-plug-into access to the signals that the board needs, and, ta-da, I just got a '>' prompt from its Tiny Basic. At the moment, I haven't puzzled enough out to enter programs (I get an "ERROR 1" - Out of Memory), but I can write statements in immediate mode and see the results (FOR loops, PRINTs, etc.). If I pull its 6116, I don't get a prompt, so I don't think it's a problem with the SRAM, but "PRINT TOP" gives me -32768 rather than an expected 4353 or similar number. So one thing I'm going to do with this is to change its baud rate from 110 bps to the max of 4800... After that, who knows. I could use an enclosure for it. For something out of my junk drawer, it's pretty cool. I'm going to write to the guy who gave it to me to see if he knows what it was used for. I used to have access to an RB5X when I worked at COSI. Now, at least, I can play around in its environment. Somewhere at home, I have a backup of our robot disk. I'll have to see if I've brought an image of that in my C-64 directory. Let me recommend the INS8073 for anyone who wants that late-70s/early-80s BASIC experience in a bread-board computer. I think you could put one together on a single (large) breadboard slab. You'd need 40 pins for the CPU, another 24 to 32 pins for the SRAM, and some sort of RS-232 level shifter, like a MAX-232. The rest is all caps and resistors. -ethan -- Ethan Dicks, A-130-S Current South Pole Weather at 21-Apr-2004 23:40 Z South Pole Station PSC 468 Box 400 Temp -81.4 F (-63.0 C) Windchill -113.3 F (-80.7 C) APO AP 96598 Wind 7.2 kts Grid 059 Barometer 687.1 mb (10361. ft) Ethan.Dicks(a)amanda.spole.gov http://penguincentral.com/penguincentral.html

Dead Mac IIfx

by witchy＠binarydinosaurs.co.uk

Hi folks, After getting a nubus ethernet card and a radius 24bit accelerator I thought I'd dig out my olde IIfx......trouble is it's refusing to power up even with different keyboards/known good PRAM batteries. It worked when I got it a couple of years ago; I even treated it to knew batteries, so anyone know of any instant fixes for dead machines? I'm going to steal the PSU from my other Mac II and see if it makes a difference....I know they're the same apart from the IIfx one has a variable speed fan.

Ebay Heartbreak (was: ebay shenanigans)

by Innfogra＠aol.com

Looks to me that the guy has a high volume of scrap go through his place, or he has access to a scrapper. A lot of his sales are chips that he sells through the vintage listing. Looks like he completes less than 10 percent of his sales. Mostly due to high prices. I am surprised at the price of Gold Scrap though. He first started off trying to sell 10 pounds of fingers. After a couple of times he dropped it to 2 pounds at a time. Sold one for $99. He seems to think scrap is worth $49 a pound. Most scrappers have found that they should list it under Gold Bullion not antiques. I sold off about 4 pounds of old pentium processors and, surprisingly, got nearly $36 a pound, which I thought was higher than the scrap value???????? Paxton, Astoria

Trouble getting IRIX 3.3 instaled.

by jkunz＠unixag-kl.fh-kl.de

Hi. I am trying to install IRIX 3.3 on a PI 4D35. I have distribution tapes and a 4D35 support tape as distcp(1M) images on disk. I created tapes >from this images with distcp(1M) on IRIX 4.0.5. I can boot the standalone tools from the 4D35 support tape. But I can't install anything. I get allways: Reading product descriptor from <where ever>: Can't read product descriptor. <where ever> is the tape device or the disk directory. When I had problems with the tapes I mounted the IRIX 4.0.5 disk by hand and pointed the install system to it with the "from" command. Same result: "Can't read product descriptor." Whats wrong here? -- tsch??, Jochen Homepage: http://www.unixag-kl.fh-kl.de/~jkunz/

On-Topic digital camera (was Re: Camera's are off topic!)

Makes automating certain operations impossible. I'll try to remember to play with my QT100 tomorrow, but I *think* GraphicConverter can deal with the native format. I'm not sure if you need the QT software installed (possibly, and then GC just uses the hooks enabled via the QT extensions), but even if that is so, GC has some half way decent automation abilities, so you may be able to use it to automate your jobs. If it can read them, you may be able to ask the author (Lemke Software) how he did it and that may help with a Linux tool (unless he requires the QT extensions, then you are just SOL for Linux) -chris <http://www.mythtech.net>

I tried Iggy Iggopolis the other day, ran WAY to fast to be usable. You can't even control Iggy, he just gets stuck in the corner... and the games timer runs out in about 10 seconds. I'd planned to try vMac to emulate a Mac Plus and see if it was better. I don't know if vMac tries to duplicate the speed of a 68k mac, or if it will try to run as fast as it can. I'd guess since ZeroGravity plays at the same speed, that's proof of decent programming. The author didn't depend on the slowness of the processor to regulate the game speed. Capt Magneto is also still mostly playable (no MacInTalk speech, but other sounds are all fine). The only problem with it is trying to fight enemies... the attack power counter goes so fast you can't even hope to use skill to get a high value, its just click and hope for a good number. -chris <http://www.mythtech.net>

Ton of *free* DEC stuff

by kdavis＠ndx.net

I'm moving and will only have room for one small system so I need to give away some things. I have a bunch of stuff that I got from a company that used to make Q-Bus cards. Here some of the stuff I is going: Boards Q-Bus and some U-Bus Manuals VAX, PDP. Some print sets Cables (Cabkits, Serial, drive, network, etc) Media (Mag & Mini tape, disks) Software (lots of dec stuff including several Distros) TK & SCSI Drives Various cabinet parts, rails, hardware, etc Hard drives (5.25 ESDI & ST506) Some Apple & Atari stuff Nothing larger than a BA23, most of the stuff is in boxes. Looking at about 15-20 boxes. *** This is local pickup only *** Preference give to someone that will take it all at once :-) Kirk

Dead Mac IIfx

by cb＠mythtech.net

>This is really nice to know. I tried bringing a few Mac II's to life to >no avail a few months back. I figured there had to be a trick because >they could not ALL have been dead. Many Macs get stuck when the PRAM battery is dead or dying. Some won't do anything, some will start but not boot (power on, spin up the drives, and just hang at the grey self test screen), some will boot but you will get no video... and some will just act plain wonky. On some Macs, there is a 'CUDA' switch (no idea what CUDA stands for... anyone know?). Its a little tiny push buttin switch on the logic board. Pressing that switch will do a deap PRAM reset, which will usually cure the dead battery issue (although if the battery doesn't get replaced, the issue will come back eventually). This can be done in place of removing the battery for 24 hours (but not all Macs have the CUDA switch, so some you are just stuck pulling the battery). -chris <http://www.mythtech.net>

Seems I have been > mistaken, I guess I will keep the CDs afterall. Not necessarily. Each machine has the right to use the latest version that was supplied for that individual machine (ie, that serial number). As far as I understand it, if you had, say, an Indy that originally came with IRIX 5.3, and had a support contract that entitled you to upgrades through IRIX 6.2 to IRIX 6.5, you could pass on the 6.5 CDs you got, along with the Indy. But if you didn't have a support contract, and SGI didn't supply you with 6.5 specifically for that Indy, then that Indy would only be entitled to run 5.3. Ditto for an O2 that originally came with 6.3 and never had a maintenance contract that entitled it to an upgrade to 6.5. You could buy the upgrade separately, and that would include a right-to-use, but the cheapest way to buy 6.5 from SGI is to buy a support contract :-) At least SGI's licences transfer with the machine, unlike DEC's. -- Pete Peter Turnbull Network Manager University of York

Does the PSU have one >output or seceral ? Have you checked if any of them are stuck at 0V? Hi Tony, I've located a set of rather poor schematics (can't really read most of the component values), but it did include 10 pages of troubleshooting information. According to this, the filaments do run off a winding on the flyback. The power supply has three outputs, a main one which is supposed to be 115v, and two smaller (thin wires/connectors) which are supposed to be 12v and 14v. Under no load, I'm measuring 140v, 15v and 17v, shich is probably about right. With the monitor connected, I'm reading about 55v on the main supply, I have not measured the other two as I'd have to remove the PSU board and tack on wires, however since it's a single-switcher design, I'd guess that they were proportinally lower as well. I do not see any obvious physical signs of failure (discolored parts, smoke etc). When I get a chance, I'll go thorugh the troubleshooting charts - they list a number of voltage measurements, waveforms and components to check for these symptoms. I'm really hoping I can get it going, as I do not have another color monitor for the ST's. (When I picked it up I thought it was another mono monitor as there is no external adjustment/indication of color and it looks exactly like my SM124 mono monitor - once I opened it I realised it was a color monitor - I guess "SC" means "Color" (vs "SM"=Mono).

Hi-res 35mm is probably better than that. Kodachrome certainly is; it can resolve a couple of thousand lines per *millimeter* under ideal conditions. Even fairly conventional fine-grain black-and-white films have been able to manage 1000 lines per mm since the 1940s. That means if you take the full height of a 35mm image, and enough of the width to match the typical aspect ratio of a digital camera (lets say 3:4), the image could resolve the equivalent of 24000 x 32000 = 768M pixels! It's not quite as simple or dramatic as that, of course. It's not just the resolving power of the film that affects the image quality, there are irradiation and halation effects to consider, as well as graininess, lens quality ("the diameter of the circle of confusion" is a phrase I will never forget). On the other hand, there are digital artefacts like edge effects to think about too. Even if you take a normal fine-grain silver halide image, under average conditions, you'd have about 15M pixels (I found that in a few references on the web). That's about 5 times more than a 3.1M pixel digital image -- except they're analogue pixels, in a sense; the size and colour are infinitely variable, not variable in discrete steps. Moreover, 3.1M pixels in the camera aren't 3.1M pixels in the final image. It depends how they're used, but in the camera, you typically need three pixels, one for each of R, G, and B, to get one RGB pixel in the image. Some techniques use even more (the Bayer algorithm uses 4). -- Pete Peter Turnbull Network Manager University of York

Ebay Heartbreak (was: ebay shenanigans)

by CordaAJ＠NSWC.NAVY.MIL

Every once in a while you win, though... I was at a 2-day hamfest last year and ran across a gentleman selling vacuum tubes, old test gear, etc. for what I considered outrageous prices. Under the table, he had a complete PDP-11/05 sitting with some other stuff. I kinda figured it would be also be overpriced, but when I asked him, his reply (as well as I can remember it) went like this... "Oh that? Thats part of an antique computer... If I had the whole thing, I'd want around $1,200 for it. it's RARE ;-) At this point, I was kind of curious, so I asked if I could look inside. It appeared to be a complete 11/05 with core memory, so I asked what he thought was missing. "It's just the _control head_", he said, "The REAL computer computer itself was MUCH larger that that!" At this point he proceeded to inform me that all computers of this vintage had to take up at least a full equipment rack. (all his companions sitting on the tailgate of his truck nodded and mumbled things like "Trust him, he's an EXPERT"). "Well, how much for just the _control head_?" I asked. "I'll take $35.00, but understand that all sales are final! And that's how I got a fully functional 11/05 for $35.00! 8-) Yep, sometimes the hunt, and the satisfaction of getting a good deal from a greedy self-appointed clueless expert can be worth as much as the find itself! -al- -----Original Message----- From: Joe R.

Other collecting activities?

by MTPro＠aol.com

I don't take the opportunity enough to engage in much actual discussion on this list, but I would like to. I also rarely get a chance to actually "play" with my keeper collection of computers, which I have recently narrowed down to just "keepers." Anyway, with a busy job, three kids and a house, time is always short, but I do find time to enjoy a couple of other hobbies. I guess after twelve plus years of ravinously reading everything about computer history, and having owned more or less every important old computer at one time or another, my interests are shifting. This doesn't mean that I won't be playing with the collection, but in a more limited way. Gotta get the garage setup finally with some work areas. As for other hobbies, I am mostly doing a lot of reading online, and reading physical books as well. I've recently added to my extensive computer history / collecting library some very nice books about Disney Imagineering, Disney history (Walt and the parks, movies, etc.), and some books on toy collecting. I'm also very interested in sceptical research and debunking of psuedoscience, bad MLM and so-called health related products. But toys have always been a soft-spot for me, which my first computer started off as (C64). My daughter has an Easy Bake oven, and I just got my son a Queasy Bake. We also enjoy the number of sets of Creepy Crawler ovens too, remember those anyone? Anyway, I'm intrigued with the history of cooking toys now and have been looking deeper into that, as well as checking out eBay for such items. My family loves to cook and we're big fans of the Food Network. I have started on the path of the history of cooking toys and the collecting of them. There are many interesting types too: ovens of course (desert baking mostly)pizza oven (Pizza Hut, Dominoes and Chucky Cheese)slushie makersCotten candy makersice cream makersgummy makerschocolate candy makersdrink makers... geez, the journey begins. So, anyone else like to expose any other collecting and/or strange behavior of their own? Ah, the kicker too . . . have their ever been a microcomputer controlled cooking toy? Could their be? Hmmmmm . . . Best, David Greelish, classiccomputing.com

Apple IIC+ Pointers on getting programs to and from machine.

I can't find any actual figures on Kodak's website. The figure I used is one I saw in a couple of places on the web, and in some old notes (see LP Clerc, Photography: Theory & Practice, sec.349). I used to be really into photography, and about 30 years ago, and I did a 3-year HND course which included a lot of theory. I've seen references to about 1/10th or even 1/20th of that in various places, too. That seems too low, but there could be several reasons for that. Firstly, it used to be the case that only Kodak would process Kodachrome -- one of the reasons professionals used to use it only for special purposes, preferring Ektachrome because it could be processed locally (and therefore quicker, and with "adjustments"). That's no longer the case, but I don't know if Kodak have changed the process (quite likely) or just made it available to other processors. I do know that professionals could get a different service from Kodak than normal users (because I could, via the college I studied at) and that could make a big difference to the results. We used to reckon a 35mm Kodachrome slide roughly comparable to a 6x6cm Ektachrome. Not that Ektachrome's at all poor: want a good colour print? Take an Ektachrome slide and make a Cibachrome print. Except I don't think you can get Cibachrome any more. The low figures I've seen for Kodachrome have been on pages where it's compared to other colour films, and I think they're suspect, because I don't think they're the result of optimal (or even close) conditions. I'd be prepared to believe that 2000 lines/mm is a theoretical figure based on grain size. If so, that won't be the true figure for a real exposure in a real camera, so I'd take it with a pinch of salt. A "good" lens on a 35mm camera typically has a resolving power no better than 150-200 lines/mm (ref LP Clerc again, and MJ Langford, Advanced Photography). -- Pete Peter Turnbull Network Manager University of York

Looking at the source for parts of gphoto suggests that's common, so I wouldn't be at all surprised to find it's the norm, even for higher-end cameras. If you were a camera manufacturer, and your competitors claimed 1.3Mpixels, would you be more honest and claim 0.4? But I don't actually know. -- Pete Peter Turnbull Network Manager University of York

Seems to me that if the book is out of print and the machine a long-discontinued one that you'd be on safe ground sharing scans of reference material for free. Apple's lawyers, never a shy group, will certainly let you know if they object. I've got a couple of hardbound Apple reference manuals here too - for the ImageWriter LQ and for the LaserWriter II and would be glad to scan portions for anyone needing such info. Seth Lewin
