Tips needed to repair Apple color composite monitor

by dastar＠ncal.verio.com

I just bought an Apple color composite monitor that needs some work. It comes on fine, and the screen goes to a bright white if I turn up the brightness. When I plug it into the computer the picture doesn't change a lick. I tried messing with all the settings to no avail. The picture stays a field of white. Any tips on how to proceed diagnosing this thing? I've got it opened up, the digital VOM is on and the soldering iron is hot.

The Amiga was a great machine for Graphics, Video, AND music during it's time (which is still ongoing). It was very easy to attach a midi interface and there were alot of really killer sequencers available. Plus, the Amiga bore the MOD music file format!

I agree with Anthony. (Why is smashing pottery always such a popular sideshow at the fair?) I have noticed a similar trend in other areas, such as sponsored events to raise money for charity. People always want to be sponsored to do something useless like walking 1000 miles or jumping out of an aeroplane (airplane). If it's a worthwhile cause they are supporting, I'll go ahead and sponsor them, but why can't we have sponsored events like "Pick up all the litter in the neighbourhood - sponsorship per bag collected"? The worst thing is, no-one would sponsor people to do something useful because "Aren't the council supposed to be doing it anyway? Why am I paying council tax? [Rant, Rant]" Sad, but that's human nature for you. Philip.

What it does have that other machines in the same class (early Mac's, early Amigas) don't have is built-in MIDI ports for connecting to musical keyboards and synthesizers. That's what I (would) use in my studio (if I had it all set up) for composition and sequencing. (Doncha just hate moving?) The 800XL is an updated version of the venerable 800. Has BASIC built-in and only one cartridge. Nice machine.

Shame, shame, shame

by maxeskin＠hotmail.com

Well, I don't necessarily see anything wrong with once in a while destroying a useless piece of junk, like a PC or a C64 (despite popular belief, third world countries will _not_ be better off with more computers). In general, moderated violence is vital in society, so that unmoderated violence is not as common. Singing and dancing is good too, but remember that Cain is the one who was a vegetarian. Of course, I have no idea why people showing off technology would want to do it by smashing stuff. Ah, that's life... >The whole exercise is such a Beavis and Butthead thing to do. > >It never ceases to amaze me that, when offered an opportunity to >celebrate in a positive manner, groups of people will choose to smash, >burn and destroy things instead.

I thought the only difference between the logic boards was the PROMs/PALs. Of course, not owning a Lisa, I can't be sure about this, alas... --- end of quote --- This is what I've heard, too. In fact, one of the newer Lisa gizmos sold by Dafax is a "ROM switcher" so you can use both the original Lisa H-roms and the modification 3A-roms without further tinkering. (I guess you'd just put up with oval circles and whatnot in Mac apps, since the ROM switcher doesn't do squat about changing the video.) All these repair manuals say "hang onto your old ROMS so you can run Lisa stuff in the future" which seems to indicate that it's feasible to revert the change. ??? -- MB

Have a Memorex Telex model B7000000 286 machine in a slim line case and a 3.5" floppy on a riser and a Quantum Prodrive 40S hard drive.

Does anyone know if this machine is a software setup or keystroke started CMOS and where to get the setup program or what the keystroke(s) are.

TOPS for PC, from sun

by peacock＠simconv.com

>Well, it says that it is a full networking OS that allows mac's and PC's to communicate, etc. seems somewhat along the lines of what francois has. also has a "secret proprietary etc etc" program disk called "RTERM", circa 1985. Daniel A. Seagraves wrote: > > If it is what I immediately thought it was, (Which it can't be, > DEC owned TOPS, not Sun...) *I WANT A COPY!* > > (TOPS-20 on a PC! The horror!) > ------- Seems there is some confusion here. TOPS-10 and TOPS-20 were DEC operating systems for the 36-bit DEC-10 and DEC-20 mainframes, circa late 60's (DEC-10) thru late 70's (DEC-20). TOPS dies when the VAX came out, thought there are vestiges left in VMS. The TOPS networking cards were essentially Appletalk cards for PCs. It was a low speed network using a Z80 SIO (or SCC?) serial USART and RS-422 drivers instead of RS-232. IIRC the speed was around 230Kbits/second (I have one in the back of a closet, haven't looked at it for a while). No relation to the TOPS operating system at all. Jack Peacock

Parallel-IDE interface for CP/M

by bobstek＠ix8.ix.netcom.com

Allison - IIRC, you were about to write some code to hook up one of these parallel-IDE HD kits to a CP/M machine with an EPP. Could this be made into a more generic project to allow file transfer over any CP/M parallel port? I for one would like to be able to transfer CP/M files from a variety of old systems to a portable IDE drive which could also be read on my PC in order to make archival copies of software for CD-ROMs. And I think there would be other interested parties as well. On another matter, thanks for the RAM 17 manual. And I'm sending you 2 unopened boxes of Dysan 10-hole hard sectored disks for your N*, plus another dozen of used, but perhaps not as used as some of yours, N* disks.

Strange MITS ad.

by rcini＠email.msn.com

Hello, all: While in the process of examining my old P-E and R-E magazines, I came across an ad for MITS from mid-1974. The ad was for a 4-channel digital handheld memory scope (model MS416) for $189. It seems to be a simple digital logic analyzer. Does any one have info on this?

In yet other backplanes, you find that it is Qbus in the AB slots and CD bus in the CD slots for part of the backplane (BA23 = three slots, BA123 = 4 slots) and then it switches to Qbus in both the AB and the CD sides. Bottom line -- make sure you know what backplane you are plugging boards into before you do so.

Shame, shame, shame

by peacock＠simconv.com

>It never ceases to amaze me that, when offered an opportunity to celebrate in a positive manner, groups of people will choose to smash, burn and destroy things instead. If it were some kind of demonstration against a particular company for some kind of social violations, it least smashing a computer made by that company would have some kind of symbolic purpose (albeit still a negative one). But to just smash something for the hell of it. How odd, seems like a natural thing to do. Many's the time I'd like to have taken the PC under my desk, loaded it into the trusty old trebuchet and slung it across the countryside. As for wanton destruction, don't knock it till you try it. Last month I had the opportunity to fire a 75mm cannon at some cars, wasted a really nice Subaru. Then I got to watch as the rest of the cars were strafed by a .50 Browning from a helicopter. It's a great feeling to watch a Lincoln being blown apart. We surely do live in the best of times. Jack Peacock

Odd Q-Bus questions 18/22bit

by allisonp＠world.std.com

< Well I'm not really a Qbus person. I never got into PDP-11s much and apa < from adding and removing boards from a uVAX-II didn't get to play with Q < much. The sort of thing I'm looking at is a little more sophisticated th < "a bus is something that connects cards together" but a little less bori < than a dry description of arcane features of signal timing and decay < (although I've read plenty of these in my time). let's see if I can do a little on this. Q-bus DECs compaction of Unibus. Qbus is a time multiplexed, asychronous, 16bit data and depending on age of the system 16, 18 or 22 bit address. It has termination and controlled loading to allow operation at high spped using open collector drivers. While a 16 bit bus it also supports various byte transfers. Q-bus is compact and fairly sparce in signals but supports memory, device, interrupt and DMA transfers using the bus data lines and a set of 10 control signals. There are other signals present for processor control such as RUN, PowerOK and Binit are examples. There are more pins than actual signals, some are redundant power for example. There are lines for bus mastering, DMA and interrupt grant/ack are examples. Most devices fall into several loose catagories, IO and memory. The lower 16bits are multiplexed on the bus before every transaction using the same lines data will be transferred on. Cards use BSYNC to capture address and start any bus cycle that pertains to them. Memory is fairly straight forward in that its timed off bsync and will use the other 9 signals to synchronize it's operation. Transactions will be read (word/byte) or write (word/byte). One of the characteristices of PDP-11s is they always read before write (a read modify write cycle is the normal thing). IO devices are identical to memory and by convention and use of BBS7 are located in the top page of the 32KW address space (1 11x xxx xxx xxx xxx). The remaining transacions of not are interrupts and DMA. Interrupts are posted via a request line that can be superceeded by another board physically (buswise) closer to the CPU and will be granted by the CPU to the higest(closest) requestor then and acceeding requesting modules. When an interrupt is granted the board will place a byte(7 bits lowest set to 0) VECTOR on the data bus that the processor will use as a pointer to a table in the first 512byts of ram (interrupts vector table PSW and interrupts service address is located in two words). DMA also has a grant acknowledge and positional priority. Once granted DMA may proceed with byte or word transfers of any length, though generally restricted to short bursts to avoid hogging the bus. The basic signals are: BDAL 0->15-L -L denotes active low signal BSYNC-L BBS7-L Predecoded bank 7 signal (IO bank) BAIKO-L Bus interrupt acknowledge BWTBT-L Bus Write Byte BRPLY-L Bus Cycle reply (must be supplied to continue the cycle or a bus time out error occurs) BDIN-L Bus Data IN toward CPU BDOUT-L Bus Data OUT -> to module Bus cycles have a distinct protocal (sequence) and timings. < Does this narrow it down a little? I'm sort of surprised that there isn' < nice description on the web somewhere.... Me too, though trivial it's not. I tried to avoid a description of each line as that is quite lengthly. Allison

Lisa 2 coversion from Mac XL

by bobstek＠ix5.ix.netcom.com

RE: the discussion on converting the Sun Remarketing Mac XL back to a Lisa 2 - I called Sun Remarketing and spoke with their most knowledgable Lisa person (thanks Marion!) who was less than encouraging about the project. According to him, it is not just replacing a few ROMs and PALs, and removing a transformer from the CRT yoke - it requires replacing the main logic board >from an original Lisa, and unless you have a wrecked Lisa, that item may be a little hard to find. On the other hand, this group always seems to have someone who, not knowing a task was impossible, did it anyway! I you're out there and have "done it" - please make yourself known!

>Two, not one, two Imsai's with Imsai disk units up for auction on ebay. Imsai disk unit as in the original 8" Calcomp floppy? Hmm, from '76? Be careful if it is, those drives had an extremely short lifespan (we experienced a 300% failure rate, every drive ordered failed, and replacements failed too).

They sent us a cardboard baffle to try to get it to work but the only real solution for us was to use a different brand of 8" drive. Did anyone ever have a good experience with Calcomp floppy drives? The controller was pretty sophisticated for it's day, used a channel type design, you sent it basic info and it read the data into memory.

Ataris

by kaikal＠MICROSOFT.com

The 800XL (circa 1983) is a streamlined version of the Atari 800 (circa 1979). Although the 800XL has 64K RAM standard, while the 800 could only support 48K, the 800 had an expansion bus that the 800XL lacks. The 800XL is a 1.79 MHz 6502 machine with 24K ROM including BASIC. It accepts most of the same peripherals as the 800, including software (mostly game) cartridges. It has 2 joystick ports that accept 2600-style joysticks. Floppy drives are available, which run Atari DOS. See http://www.geocities.com/~compcloset/atari800XL.htm. The Atari 520ST (circa 1985) is a 16 MHz Motorola 68000-based machine that was created to compete against the Commodore Amiga (Atari almost acquired Amiga Technologies before Commodore did, and was always jealous of that fact). It indeed runs a GEM-based GUI and the TOS operating system. The STf version has an internal floppy drive, and the STfm version has a floppy drive and RF modulator. See http://www.geocities.com/~compcloset/atari520stfm.htm.

TOPS for PC, from sun

by fauradon＠pclink.com

Right but the original post was about the PC-MAC network and not the DEC OS thus the path the thread is taking. There was also a TOPS for UNIX (Sun 386). Also TOPS could work through Ethernet (used mostly when UNIX was involved) wich would allow for more that just PC-MAC networks. According to the Book "Networking with TOPS" the original version was made by SUN. -----Original Message----- From: Jack Peacock <peacock(a)simconv.com> To: Discussion re-collecting of classic computers <classiccmp(a)u.washington.edu> Date: Monday, August 24, 1998 12:18 PM Subject: RE: TOPS for PC, from sun > >>Well, it says that it is a full networking OS that allows mac's and >PC's >to communicate, etc. seems somewhat along the lines of what francois >has. also has a "secret proprietary etc etc" program disk called >"RTERM", circa 1985. > >Daniel A.

Parallel-IDE interface for CP/M

by bobstek＠ix6.ix.netcom.com

Allison - IIRC, you were about to write some code to hook up one of these parallel-IDE HD kits to a CP/M machine with an EPP. Could this be made into a more generic project to allow file transfer over any CP/M parallel port? I for one would like to be able to transfer CP/M files from a variety of old systems to a portable IDE drive which could also be read on my PC in order to make archival copies of software for CD-ROMs. And I think there would be other interested parties as well. On another matter, thanks for the RAM 17 manual. And I'm sending you 2 unopened boxes of Dysan 10-hole hard sectored disks for your N*, plus another dozen of used, but perhaps not as used as some of yours, N* disks.

What I picked up from the ebay auction

by Anthony.Dellett＠Staples.com

Well, not only did I win the Ebay auction for all the 70's electronics parts (he didn't even want my winning bid), I went over this weekend to fill up my car (a 1990 Ford T-bird). I am going back to get the rest next weekend but I was able to fill my then empty trunk with 74lsxxx parts, all brand new in tubes (the guy believes there is at lease one tube of every part in the series in there). My back seat is full of 3M ribbon cable (various wire counts) and tons of din and card edge connectors. I think I grabbed a box full of 68K and Z80 processors also. What I'm nabbing next week; A NEC Spinwriter with a bunch of spindles, a box full of 10MB Priam hard drives, a box full of Shugart 8" floppy drives, more din and card edge connectors and (if I can get Allison's help) a 19" 6-foot rack :) Once I can go thru and sort all this stuff, I'll probably be offering them online for people that need them. I'll probably just charge for shipping, maybe a meager fee to offset the cost of storage. Tony

It's available for just about every computer platform there is (or was), and can deal with communications channels that X/Y/ZMODEM will just stare blankly at (for example, one-way-at-a-time async channels common on IBM mainframes). Even better, it can be just as fast or faster than ZMODEM. I use it just about every day to move data between RT-11, RSX-11, CP/M, VMS, Unix, MS-DOS, OS/8, etc... ----- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology Voice: 301-767-5917 7328 Bradley Blvd Fax: 301-767-5927 Bethesda, MD, USA 20817

Odd Q-Bus questions 18/22bit

by mbg＠world.std.com

>It's definitely hardware only. See my other reply to Daniel as to why I >don't know exactly what's on it.... Is there any service which duplicates fiche? (and produces something readable?) I remember making fiche for listings of various things back when I worked on some DECsystem-10s at the PK1 (parker St, Maynard, MA) facility. The fiche was produced by some device which read magtapes with machine-readable listings, produced on the -10... At one point, I did what was required to produce a set of fiche with the RT-11 listings on it... this was RT V2C.

OK, I've got the RX02 virtual disk images I want on my 486 (it's the one with the 1.2Mb floppy, booted into DOS, and started up 'putr'. I made a RX50 using putr, and go to copy the smltcp.dsk image to the RX50. Unfortunatly it complains that there isn't enough room. I take it that a RX50 is less than 500k? I think the image is 492k. Is there some way that I can split the disk images and then recombine them once I've got them copied over to the /73? I'm just not feeling energetic enough to want to move a RL02 drive around and juggle the controller between my MicroVAX and /73 to get the files transferred tonite. Zane | Zane H.

The only thing I can think of which might affect whether they are readable is whether the disk images you have are sector-by-sector image copies, or block-by-block image copies. If they were copied using one technique, but read using the other, then you'll actually be mixing unrelated sectors together to form a block. I would have to check the source (or ask Bob) which technique is supposed to be used to make image RX01/02 copies so that they work. >I'm wanting to use them on my SMS-1000.

Lisa II/"whats the matter with my Lisa?"

by Marion.Bates＠Dartmouth.EDU

--- <cdrmool(a)interlog.com> wrote: > > What's the matter with your Lisa? > > -- MB > I don't know apples, I usually work on P.C.'s, so I'm not sure. When I try to turn it on it chirps. I've experienced that with monitors before and the man who gave it to me (yes, you heard that right) said that it had been working but the monitor was not coming on anymore. He also added that he was able to get it up if he gently wiggled the circuit board at the back. After hauling it down from the bedroom into my "lab" today and asking it nicely to work, I wondered if it isn't the power supply instead/as well. Colan --- end of quote --- Re: wiggling the circuit board. Perhaps the card's contacts are dirty -- try rubbing alcohol with a lint-free cloth, you might get lucky. The chirping sure sounds like a power supply thing to me...though for what it's worth, that was a real common problem (easily fixed) with the old compact Macs (128, 512, Plus) that used the analog board power supply. There was a distinctive ring of solder points, visible from the non-component side of the board, where the flyback transformer was attached (the blocky part with the little suction-cup connector that sends high voltage to the built-in CRT). Over time the solder would crack from repeated heat expansion and contraction. The symptom was either no video, or a more-or-less chirping sound. Often the solution was as simple as resoldering those points -- maybe there's some similarity with the Lisa's internals? Dafax Processing has replacement power supplies for $250 (gouge! Sun Remarketing sells a entire Lisa for that, I think. But it's Mac-modified, bummer.) Maybe there's a discount if you trade in your old one, I don't know. Dafax's number is 718-746-8220, and Sun Remarketing's is 1-800-821-3221 (maybe they have parts for less?) Good luck! -- MB

It's very very possible that both of the working models have already undergone the "Mac XLectomy". Is it possible to reverse the Macification of the Lisa? I want to run the original virgin Lisa software :) I believ3 that the dead Lisa still has the motherboard, and that it is an original Lisa 2/5 motherboard. Can I just make a swap, or is the XLectomy more insidious? --- end of quote --- The Macintosh Screen Modification involves changing out some ROMS (boot and video) and replacing the yoke coil, as well as performing voltage and video geometry adjustments afterward. It's technically reversible if you have the old parts -- where to get them, I don't know. You'd need the voltage and screen-size specs to get it just right (and avoid blowing the power supply). Sun Remarketing still sells the mod kit, so perhaps they have the parts that were removed to do modifications? -- MB

TCP/IP for RT-11

by healyzh＠ix.netcom.com

OK, I've found the TCP/IP distributions on the Kent University web site. The thing is, they're on RX02 disk images of some sort. How on earth do I deal with these? They obviosly aren't compatible with Bob Supnik's Emulator, at least I couldn't access them. I'm wanting to use them on my SMS-1000. It is a PDP-11/73, 4Mb RAM, Ethernet, and a funky drive controller which in the case of the 5.25" floppy I believe is able to emulate either a RX50 (how it currently is set) or a RX02. I'm wondering if the RX02 mode requires the model with the 8" drive, which I just happen to have in a shed out back (obviously not as decked out, and with a dead hard drive, but still a /73).

Lisa II operating software

by Marion.Bates＠Dartmouth.EDU

--- Tony Duell wrote: [Re: copying Lisa disks w/o a working Lisa] I think the only way is to find some other Lisa 'up and running'. --- end of quote --- There is another way, I think, using Mac utilities. Mr. Craig sent me several Mac-formatted floppies containing CompactPro archives of disk images of the LOS disks. (Whew! Did you follow that?) He also sent along the older version of Apple's Disk Copy (4.2, I think) which will happily make disks from images it cannot mount. (It also knows to make an 800k floppy be 400k if that's what the original image calls for.) Obviously, somewhere along the line, he was able to make the images from the original Lisa diskettes, but I don't know the details of this -- Disk Copy must be able to make images from weird disks (I know it can do ProDos ones.) Incidentally, there is a way to de-serialize LOS diskettes using FEdit -- I don't know where your set of disks came from, or whether they've been used. (The LOS install disks have to be un-write-protected because the first time you install the software, the installer reads the Lisa's unique hardware serial number and writes it to the disk for piracy prevention. If you ever try to install the software on another machine, it won't let you.) What's the matter with your Lisa? -- MB

I'm Back!

by SUPRDAVE＠aol.com

In a message dated 98-08-22 15:57:55 EDT, you write: << Wow! It's amazing how different a CRT looks after three weeks' break. I don't even feel like sitting at a computer that much anymore. Sorry to start off again on a bad foot, but does anyone know why a certain hard drive of mine won't spin up unless whacked firmly against a table? Is there anything I can do? This is a laptop drive. >> stiction. nothing you can do about it.

Lisa II operating software

by bobstek＠ix7.ix.netcom.com

Let me make an offer (without knowing exactly what I'm getting into...) I haven't been following this thread too closely because I've never had a Lisa or even a Mac...until yesterday. I now am the proud (but ignorant) owner of a fully working 1 MB Lisa 2 (the Mac XL variety) with the 10 meg HD and 3.5" disk. If given explicit instructions on how to de-serialize, I'd be happy to make copies of whatever disks you would like. And since I've been short of time (and I'm lazy!) I'd appreciate a few choice URL's with solid info of all sorts on the Lisa - less on its history and more on hardware and software, operational hints, etc. Bob Stek bobstek(a)ix.netcom.com

Mac Portable problems (was Re: Mac Portable batt charger)

It is Apple-labeled and has an Adaptec-based SCSI controller. Could have Apple taken a stock CP hard drive and grafted a different controller card onto it? The interface from the drive hardware to the drive electronics seems to be standard (i.e., an 18-pin pin-header interface), so maybe Apple swapped controllers. It does have a proprietary SCSI pin-out, though, for which an adapter is available to connect a sdandard SCSI drive to the portable.

Apple ///
