Mac Plus with (minor) issues

by cb＠mythtech.net

Sounds like the barrel rectifier at position CR5 on the analog board is going bad. Tech book I have here says its a MR824 rectifier. I had to look up the position and the part number in a book I have (Dead Mac Scrolls), but I have done this repair on a few Mac Pluses (same analog board as the 128 and 512), and they had similar symptoms. They had the Chirping noise, as well as the right side of the screen would move in and out (which would appear that everything is shifted left like you describe). Notes from the book. Original rectifier is a GI854, R-SI, 600V, 3A... and they recommend replacing it with a MR824, R-SI, 400V, 5A to avoid having the problem come back. The rectifier is kind of top center of the analog board. The analog board from those Macs was notoriously flaky. Lots of under rated parts that burned out easily. Probably Apple worst power supplies. Ironically, the 2nd worst are the CRT iMacs that brought back that same style computer. And ironically, the iMacs are bad for the same reason, under rated components that burned out from normal use. You would think Apple would have been more careful the 2nd time around :-) BTW: While you are in there working on the analog board, check and possibly resolder joint J4 on the main cable on the center of the board. Its pin 1 on the cable. That joint was bad on I think EVERY Mac Plus I worked on. So there is a pretty good bet that even if you aren't having problems with yours now, you will in the future. The solder would split off the board causing the cable to lose connection, causing the video to blink out. Smacking the side of the case would cause it to restore temporarily... its the only time I've had a computer company give me an official "repair" of "whack the side of the case" =:-O -chris <http://www.mythtech.net>

Mac Plus with (minor) issues

by mtapley＠swri.edu

All, Two separate (?) issues with my Mac Plus. 1) Screen display is too far to the left. 2) System seems *very* sensitive to voltage setting. What I've got: Mac Plus (upgraded from 512k), original mouse/KB Brainstorm 16MHz 68000 upgrade Kensington System Saver Mac (switch, fan, and surge protector, mounts on top of system). La Cie external SCSI hard drive, 230 MBytes Analog (Radio Shack, automatically suspect) VOM. Mac OS 6.0.8, 7.0.1, 7.1 (chosen by System Picker utility) all on HD Screen Display issue: Everything (all pixels) is shifted uniformly to the left about 5 mm. I found the "width" setting on the analog board (well duh, read the label on the cardboard shield) and fooled with it (system on, plastic tool). Works fine, image gets narrower and wider. I can set it narrow enough that pixels are all on the phosphor, so the system is usable - but it's aesthetically slightly annoying to have everything to the left of where I expect it. I could not find a setting to shift left/right. Problem is present either with or without the Brainstorm installed, so I don't think it's related to that. I *think* the problem first appeared when I took out the "Elf Armor" mu-metal ELF shield that I got back when that was hot psuedo-science, my wife used the machine a lot, and we were expecting our first child (see the connection? :-) ). Significance of that is I had to unplug the cable >from the back of the CRT, so might I have knocked something askew? Voltage sensitivity: System started occasionally resetting itself. Opened it up, stuck the VOM on ground (frame) and 5 V (using the pin in the middle of the Analog -> Digital board connector, at the digital board) and found it reading a *little* (maybe 0.05 V?) shy of 5 V. OK, (duh, read the label on the cardboard analog board shield again) set the voltage higher, with system running. I can set it quite a bit higher, up to around 5.1 V. System keeps running. However, when I power-cycle at that setting, it goes into an endless loop of "chirp, chirp, chirp..." and the VOM stays near 0 V (wiggling at each chirp). I assume that means there's an overshoot on 5V coming up which triggers the crowbar, which sets up for a repeat. Q1) Is that supposed to work that way? I'd expected the 5V rise to be critically damped or better, so no overshoot. In other words, I'd expect if it'll continue to run at a given Voltage setting, it'll start at that setting. Have I got a latent problem forming? OK, sooo... set the Voltage back down some, try the "reset" button.. (repeat a few times) ... "Bong" ... starts up nicely ... runs a while and then freezes. (Here and below, "freezes" means some sort of bad instruction. Could result in lock-up, could mean drop into MacsBug, unable to continue, could mean reset.) This behaviour is not present unless the Brainstorm is installed (at least not obviously. It could be true but with a longer time constant between freezes). Sigh. So try setting Voltage barely higher. Works, but freezes *sooner*. Hmmm. Voltage lower. Works better. Voltage lower. Finally found a setting very slightly below 5V, (mmmm..maybe 4.98 V?? But remember the instrument I'm reading from here...probably about 1 significant figure) where it seems to run indefinitely ('til bedtime, anyhow). Q2) I thought that all digital stuff basically ran better until it over-voltaged - which the crowbar was supposed to prevent. So I'm surprised to see freezes/crashes at *higher* voltages (but still low enough to avoid the start-up overshoot) but see them less frequently at lower voltages. Q3) I assume there is a minimum voltage at which I'll also start to see freezes/lockups. True? Am I better off hunting for the lowest possible voltage, or try to find a "happy medium"? Q4) Have I got some incipient problem (dying isolation cap?) that is closing my window of working voltages? Warning: I'm on digest mode, the system is at home and I'm usually at work while accessing email, so my response time is likely to be ~24 hours for anything that requires tests/measurements. And then there's the kids' YMCA soccer (football) league .... TIA and no urgency, as the system appears to be running at the moment (raps forehead soundly) 'Knock on wood'. Kids are getting hooked on "Sim City" while I'm at work. But the Brainstorm may cure that...Sim City appears to run twice as fast with the 16MHz upgrade as it did with just the original 8MHz processor. Which reminds me: The Brainstorm is on a little daughterboard with 2 other IC's. The daughterboard plugs into a socket which is installed piggyback atop the original 8MHz 68000. There is also a flying resistor that solders to one leg of another component a short way away on the motherboard. If I pull the Brainstorm daughterboard off, and desolder the resistor lead, the system works just as before, with the 8 MHz CPU. If I plug the Brainstorm into the socket and connect the resistor, the system runs (see above, sometimes) at 16MHz (apparently). (FWIW, there are a couple of other modifications to the motherboard. I *think* they are just IC replacements.) I *think* this means that when the Brainstorm is plugged in, both 8MHz and 16MHz processers are running simultaneously. Bonus Q5) Is that right? Isn't that a recipe for thermal and electrical disaster? (I guess not, it runs, but....) -- - Mark 210-522-6025, page 888-733-0967

6809 (was: Anybody ever use Aztec C for APPLEII?)

by dave04a＠dunfield.com

>> I'm not as familiar with the 6809 as I am with the 6502... what differences >> in architecture make it better? Larger stack frame? More (and larger) >> registers? > It also supports more addressing modes than the 6502 like position >independant (indexed off PC) and indirect addressing (in C, this would be >dereferencing a pointer). It also has a fairly orthogonal instruction set >which also helps in compiler writing (in my opinion). Of all the 8bit CPUs, >this happens to be my favorite. One of the biggest advantages of the 6809 to a compiler is the fact that it does all kinds of stack relative addressing. The 6502 can't even push/pop all of it's registers let alone perform relative or indirect stack addressing with them... This ability makes it very easy to deal with C's stack based local variables. For example, you can access memory on the stack (or through any index register) with a 0, 5, 8 or 16 bit offset, and you can use an 8 or 16 bit accumulator to calculate an offset. You can also perform indirect operations using stack based pointers, all in a single instruction. Plus, all index and stack registers on the 09 are 16 bits. The 6502's 8-bit index registers are somewhat at odds with C's notion that a pointer can point 'anywhere'. So, on the 6502, you end up using zero page 16 bit "registers" a lot, and these involve more overhead to manipulate. The 6809 is also my favorite 8-bitter (perhaps that's why there's 6 CoCo's in my collecion). The very first edition of my C compiler was targeted to the 6809. At one point I even designed my own portable 6809 computer (hardware and software), you can see it (and even try it out with a simulator) at my "old computers" page: http://www.parse.com/~ddunfield/museum/index.html Look for entry called "D6809". In addition to the OS, the system has a "bunch" of utilities, several editors, an assembler and a simple implementation of APL. there's even an 8080 emulator which allowed me to easily bring over code from my Altair which was my main computing platform prior to this one. It's disappointing that the 6809 never received as much acceptance or use as it should have. It was truly in a class by itself. Motorola documents show two circles, one containing the words "8-bit" and one containing the words "16-bit". A third circle, linking the other two contains the word "M6809", and this is a good description of the part. It was an 8-bit CPU with a great deal of 16 bit capability. Btw, I have scanned the "Motorola M6809-M6809E Microprocessor Programming Manual" and a fair bit of other 6809 reference material, which is all available on my site.

Fastest VLB Video Card for Windows 3.11

by teoz＠neo.rr.com

A while ago I put together a 486/66 system to play around with all my windows 3.1 apps I have used in the past. I was wondering what the fastest VLB video card ever made for windows 3.1x was. I remember Diamond bragging about its Viper cards back in the day being the best, but who knows. Google has allot of information about what the best DOS gaming card was, but not that much on windows 3.1 (which is what I am interested in). Also what's the best video intensive benchmarking app to test out cards with? I have the following cards (and others but they are slower): Diamond Viper VLB 1mb VRAM Diamond Viper VLB 2mb VRAM (while both have the P9000 chip for windows acceleration they have 2 different chips for vga) Diamond Video 3000 (Stealth 64 Video Vram VLB) 4mb (S3 968 Chipset) Diamond Speedstar pro VLB 1mb DRAM Hercules graphite 1mb VRAM (IIT chipset) Matrox Plus 2mb VLB (early matrox chip and a very long card that has space for another 2mb vram) These cards are from the early 90's so it should be on-topic for the list.

Yes, absolutely - and I did run OS/9 on my CoCo sometimes when it was an "in use" machine... however I do recall that when initially getting going with the machine "out of the box" it was frustrating to figure out why they had done some of the things they did - I guess the real problem is that the CoCo was designed "on the cheap" and did not have things like a real serial port, and relied on a lot of ROM software to make other devices work. It's funny - in a way you've made my argument for me - That you needed to run a completely separate third-party system in order to allow the CPU to be used anywhere near it's potential is pretty much the point I was making. Btw, I did not buy my first CoCo to run OS/9 - I wanted to put my own os (CUBIX) on it, and I found it required much more learning/understanding to get to the point where I could "take over" the machine than it did with other systems (Boot puts one sector >from disk-0 here, here's the disk controller, here are serial ports to talk to terminal - a bit of typeing and you are up and running...). Having the ability to make use of existing ROM code for the devices - at least initially - would have helped. All I'm saying is that this ROM heavy/limiting design was one factor (and only one in a larger list) that prevented the machine from widespread acceptance/third party support. This is consistant with the CoCo's design as a "cost is everything" home "appliance" console, not a serious business/scientific machine which is what the 6809 CPU was worthy of. And this is not necesarily a complaint - just an observation as to some of the reasons a decent machine with an outstanding CPU didn't do better than it did. Unfortunately it is the only common machine using the 09 that most people knew of, and this did not help to win 09 supporters. I believe SWTP made a nicer 6809 machine, however I never did get my hands on one :-( -- dave04a (at) Dave Dunfield dunfield (dot) Firmware development services & tools: www.dunfield.com com Vintage computing equipment collector. http://www.parse.com/~ddunfield/museum/index.html

More 6809

by chad.martin＠fli-invent.com

Just to let you guys know, there were much larger 6809 systems. The 6809 was a great processor. I worked for many years on a 6809 system with 4Mb ram, scsi disk interface with hard drive and ms-dos 3.5 floppy, 68030 floating point co-processor. This was in use from about 1980 until 1992, when superceeded by the new system. The 6809 was retained for so long due to the software investment. Originally it had a custom disk interface to 5.25 floppy only, which was upgraded to scsi and ms-dos fat file format around 1988. It also originally had a smaller stack based floating point chip, but we needed faster float speed for coordinate calculations. So we upgraded to using the floating point co-processor that was used with the 68030. All of this and the memory managment was custom hardware. It started out being a couple of boards, but later was reduced to one board for all the cpu stuff. These systems also had several other 6809's in them. Originally the pattern rec vision system used one also. The material handling system, and motion control axis used the smaller 6805s in them. It was used on the Kulicke & Soffa wire bonders, used to manufacture computer chips, including Motorola of course. http://www.kns.com/prodserv/equipment/8060.asp Chad Martin

Help ID/recovery of unknown word-processor files?

My brother interviewed two women who drove across the U.S. by themselves back in 1920-something (a substantial feat, if you know anything about U.S. culture then or 1920's roads and automobiles), published a little 500-copy book of it. It's long since disappeared, and never got the attention it deserved. I want to put it on the web. He's gone now, and so is the computer the files were typed on, and I don't even know if it was CP/M, Mac, PC or what. They have extentions of "CWK" and simple 8-char filenames.

SCSI disk spin-down question

by julesrichardsonuk＠yahoo.co.uk

Not sure if this it OT or not! Anyone know if all SCSI disks support spin-down under software control? Is it a SCSI-1 and above thing, SCSI-2 and above, or something which is only implemented by some manufacturers? (Or maybe it only applies to modern disks with an SCA infterface even?) I'm just thinking about putting some more drives in the home fileserver - but it's noisy enough already, hence I'd like to be able to power-down disks I'm not using except for when I need them. Possibly even hooking into samba code to spin the disks down after x minutes of inactivity and only spin them back up when a data request comes in... As all my classic comp data will be on said drives I suppose that sort-of makes it on topic :-) cheers Jules

Does anyone have the Nov 1980 issue of "Electronic Design"?

by dickset＠amanda.spole.gov

In researching the INS8073 CPU, I ran across an ancient Usenet article that mentions that the 22-Nov-1980 issue of "Electronic Design" has an article that might be of interest. a) might anyone on the list have that particular magazine, and... b) would you be willing to scan the article? I can accept just about any format you might want to throw (TIFF, GIF, PS, PDF...)

Stuff in Portland, OR

by healyzh＠aracnet.com

Is anyone in the Portland area interested in collecting a bunch of misc. computer (as well as probably some electronics) stuff? It's for local pickup only, and until I start digging it out, I don't know what all will be in there. Definitely PC realated stuff (PCI era), and at least a little Sun stuff. Probably some other cool stuff as well, especially if interest is expressed, or cash offered. If no one in the area is interested, it's probably going to get dumped on BadWill. The classic stuff really isn't in much danger at the moment, I just have to do something to free up some space (if someone interested in picking stuff up is interested in classic stuff as well, some of it's available). I'll probably be dumping the non-classic stuff this weekend if I haven't heard from anyone. Remember LOCAL PICKUP ONLY! Zane

DEC VAX 11/xxx wanted

by jwest＠classiccmp.org

My previous deal on a VAX 11/7xx fell through, so I'm back looking for one. I would really like to get an 11/750, but would settle for a 730. Anyone care to talk trade? Email me offlist if so! Most of my trading stock is HP gear, but I have some DEC gear too. Guess there is always cash if you want to go that route. Regards, Jay West --- [This E-mail scanned for viruses by Declude Virus]

I'm pretty sure I'd be interested in another > audio dongle for the SparcStation 1 if indeed you do have some. Hiya. This took a while, because I had to do quite a bit of digging, and I'm still not done. - But I have a Sparc 1 audio dongle still in the original plastic bag -- plus a few other ones that have actually been used a bit. I thought that it was somewhere in the bottom of the pile, and I was right. (Imagine that!) - I also have a big pile of various SCSI cables that needs a home: these are ones that I used with my Sparc 2 and various external devices, and they're a mix of micro-SCSI (like the connector on the back of the Sparc), DB-50, and Centronics-style. There's at least: 3 DB-50 to Centronics, ~4 ft 4 DB-50 to DB-50, 2-3 ft 2 DB-50 to DB-50, 1 ft 2 DB-50 terminators 2 DB-50 to Sun micro-SCSI connectors, 3 ft 1 bizarre IBM double Centronics...you tell me, it's in the box plus: about 4 more Centronics-style cables I found yesterday - I have an SBus expansion box. It's a pizza-box the same size and shape as a Sparc 1/2, but designed to let me you plug in more cards. But: I don't have the connector/card for it. I have seen those offered around the 'net from time to time, but not for a while. - I have a Sun 911 enclosure. This is about twice the height of a 411, and it's designed to hold 4 SCSI disks. Caveat: while removing the disks >from it ('cause I was still using it) I noticed one loose wire on the big harness that connects everything. I don't know if it was (a) always loose and thus not a source of any problems or (b) I knocked it loose while pulling the disks. I'm just not inclined to mess with it. - I have a couple of AUI-to-10BaseT transceivers with attached cables: one end plugs into the AUI Ethernet port on a Sparc 1/2, the other end (about 10 feet or so) has a 10baseT plug. Handy, but I don't need them any more. Cost for any of this? Make me an offer that's at least enough to cover shipping. ;-) Really. If you can use it, and I can get it out of here without losing money on the deal, it's yours. (I'm going to be moving soon, so the less stuff I have to pack...) There's other stuff as well but I haven't made a real list yet: old SunOS distributions (at least three of the SunOS 4.1.3/4.1.4 era), Solaris distributions (2.5, 2.5.1, 2.6., 2.7, and a still-stealed 2.8), and so on. I'm making a list now and will send that too. ---Rsk -- 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 ]
