  1. It seems that the Macintosh IIci, like the IIcx, only like to work properly with fixed resolution 640x480 monitors. However, I have had my IIcx running on an Apple Multiple Scan display and a couple of standard VGA monitors, with mixed results. A common problem is a green tinge to the picture. At least you got yours working. System 7.1 is the best for the Macintosh II series in my opinion as it will give you a good deal of functionality but not slow the System down as much as 7.5.
  2. The maximum RAM listed for this machine is 36MB, though this may be different with the PPC upgrade. It should probably say Revision C on it. I have a Revision B cage and I think it says something like that (I don't have it handy at the moment). The earlier cages, A & B, can be used with memory cards and compact flash card adaptors, which is handy if you fancy running the PowerBook off flash memory rather than the internal hard drive. There are some details on how to go about this on my Retrochallenge Winter Warmup '08 page. As far as I'm aware the Revision C cage is the only one y
  3. I recently picked up an Apple IIc with monitor, and although the IIc is working perfectly the monitor appears to be completely dead. Having stripped it down I've discovered that the probable cause is a resistor, R514 (next to the flyback), which is toasted. Unfortunately the resistor is so burnt that the coating has fallen off, thus it is impossible to tell what value the resistor was. The resisitor is knackered so an ohmmeter reads infinite resistance. I've checked the two fuses inside the monitor and they are fine. What I need is a circuit diagram for the monitor (model G092S, order no A
  4. I did spot that lot for sale and was quite tempted to take a road trip down and get it, but I'd never have had space for it in my (small) car or at home! Glad someone can appreciate it though.
  5. That is a good paint job, which has a sort of 1980's "boy racer" appeal to it. It's the sort of style in which you might see a Mk 2 Escort or an Audi Quattro painted.
  6. There were four models of adaptor made for the 100 series PowerBooks, which differ in their power rating. Have a look at this article: http://support.apple.com/kb/TA32393?viewlocale=en_US. Although the connectors are the same, some adaptors are not universal and care should be taken particularly with the PowerBook 100 and 150, where an adaptor under 19W must be used. Although not completely logical in electronic terms, (the PowerBook should only draw the current it needs), higher powered adaptors can and do toast 100 and 150 models. The 1400 adaptor should work fine with the Duos. Very
  7. I was rather bemused by the message myself, hence why I posted the screen grab. The setup with the files shown was how I received the machine from its previous owner, it has since been tidied up a little and I will probably re-install it at some point. It is highly likely that the machine started off with System 6 and was later upgraded to 7.1, which it is running now. Threshold is a useful little application that allows you to monitor battery voltage and change the thresholds at which the System produces low power warnings. It works on the Portable and most (if not all) 68K PowerBooks.
  8. It definitely is possible to run a Portable off a 100 series adaptor but you may get mixed results. I have safely used a 24W 165c adaptor with mine before and it seems to function just fine like that. However, I find there is a lot of difficulty in starting up with no battery installed and it often gives a Sad Mac. Fortunately in my case I managed to source a lead acid battery that fits and that coupled with a normal Portable adaptor or a 100 series adaptors seems to work fine. Maybe try yours with a 100 series adaptor and the old battery in its compartment, or possibly source a suitable repla
  9. A good way to get started is to get a copy of the Apple Service manuals for all the older Macintosh computers. You can often find them sold as PDF files on CD or DVD, generally on eBay for very cheap, which in my opinion is the best way to have them. They are also available in certain places online that host these manuals but this is generally not as consistant as a disk version. These manuals are written for practically each and every model, though there are some that apply to a line of similar machines. They describe the computers in great detail and always have a "take apart" section as wel
  10. I find that leaving machines in a well ventilated area is generally the best way to get rid of a smokey smell. Perhaps somewhere that is covered but has a good airflow through it (such as a shed). Also, giving them a good wipe down with a damp cloth will help.
  11. Just to re-iterate here about my 100: the screen on mine lights up when power is applied and displays irregular horizontal lines with a reddish/pinkish hue (although sometimes they are white). The screen picture disappears when I hold the reset and interrupt buttons simultaneously, though the screen's backlight still stays on. I haven't tried the machine with a disk yet so I might do that to see if it is simply a video signal issue, but I reckon the strange chiming noise suggests there is another problem somewhere.
  12. Sounds good! You have 2MB of RAM which means there is a RAM expansion daughter card installed - 1MB on motherboard and 1MB on card. It is therefore possible to add two 30 pin SIMMs and upgrade your Classic to the full 4MB should you wish to.
  13. I did try the other day and although it did load, things on the pages were in quite a different place than they were on my G4. The last forum appeared roughly the same on 68K browsers and modern browsers, and the one before that was virtually identicle on both. The new layout is actually growing on me a bit now and I especially like the fact that you can turn of signatures. That makes threads much more readable and makes it easier to concentrate on the topic being discussed.
  14. That sounds like a brilliant deal to have, and a win win situation for both sides: they get rid of the unwanted stuff easily and you can keep what you want. The risk there of course is that you could end up ammassing an enormous amount of stuff - I know that is certainly what I would end up doing in that situation. It would be good to hear of interesting conquests through this in the future so please keep us updated!

    B&W G3 300 MHz

    I've heard it is pretty easy to overclock B&W G3s, it is just a case of shifting some jumpers about (no soldering required). My B&W G3 was overclocked from 350MHz to 450MHz by the previous owner and it has served reliably for years.
  16. Woah, not so sure about this new layout myself. It doesn't seem to render properly in older Mac browsers such as iCab, which is a big downer in my opinion since this is an old Mac forum. Although, I've never been happy with the appearance of the forum since the Great Crash a couple of years ago - I thought that original OS 7/8 style was perfect. The new style will probably grow on me with time but I'm definitely in support of a retro Mac OS theme for the future.
  17. Schools in the UK seem to be funny about letting people have their old equipment, mainly from the liability sake. If someone buys or takes an old computer from them and it sets fire to their house, it is likely that person would claim against the school and win everything. It is an unfortunate attitude that seems to have crept into meany aspects of British society. However, that is just from an official standpoint. It is unlikely you will find a school or college openly selling off old equipment but often by asking the right people it is possible to do a deal. Some places also have technic
  18. My current place of work has been known before to deliberately break equipment before scrapping it so that it is of no use to anyone. This was back in the day when they threw everything in the general waste skips, including computers, and they didn't want anyone salvaging stuff. Despite being broken, occasionally useful bits (RAM, drives etc) could be recovered from machines. Fortunately they are now required to use a proper electronics disposal container and they have mostly stopped smashing things before they go in. However, I did see them compacting a load of stuff into the container by ram
  19. When I was at school there was a lot of old Mac software sitting in boxes in cupboards and drawers. Quite often it would gather dust and then get chucked out - fortunately I managed to save the vast majority of software before that happened to it. The school was always glad to give away their old stuff to someone who would appreciate it. Computers tend to rot quite quickly if they are left outdoors in the rain for any length of time. I have rescued a couple that have been out for a couple of days and often after drying they work fine. Once I even found a SE/30 that looked like it had been

    Two conquests.

    Nice finds - I always enjoyed having a raid through cupboards when I was at school, which is how I started my Mac collection. It is a good idea if you can to befriend the school technicians as they can often provide pointers to the location of interesting equipment and in some cases will grant permission for it to be taken. This worked for me but it really depends what the technicians are like.
  21. When I saw the first picture I actually thought it was an LC with a real pizza box for a case. That has now given me an idea for my next project.
  22. That was a fun BBS, unfortunately I only had the chance to play with it for one evening until major work related obligations got in the way. I laughed when playing Microbandit when I got something like $45 and then was mugged! Muggings aside, it was a very generous bandit.
  23. I initially tried charging the battery because it is in fact a third party battery (made by "Absolute") that looks more modern than the PowerBook itself. However, it is definitely dead. Exactly the same thing happens. I also tried holding down the programmer's and reset buttons with the power connected to see if anything else would happen (this can sometimes revive Macintosh Portables). This action makes the screen backlight come on only, nothing else. The adaptor I am using is a 15W 100 series one (7.5V, 2.0A). This adaptor is known to work perfectly with my 145B and 165c. I reme
  24. I picked up a PowerBook 100 on eBay the other day that was sold as "working fine months ago, but charger broke and hasn't been used since". Well I got it home, plugged in a 100 series charger, (one of the earlier low current ones), and tried powering it on. It does do something, but not what I expected. Instead of lighting up and giving the startup chime, the screen lights up with reddish horizontal lines across it and continually makes a chiming noise, like the startup chime but "minor", more sad. It's not the Chimes of Death because I know what those sound like - instead my PowerBook is
  25. Sometimes cables, cards and SIMMs can become dislodged, which could cause problems. I've found that in 80 percent of cases when soemthing stops working, taking it apart and re-assembling it does the trick.
