  1. I hope this is okay to ask this here . . . I have a newsletter that I put out at least once a year. (My current subscribers get a PDF edition for free when the newsletter is released and I offer printed copies and back issues for sale.) It's not about computers but more eclectic in nature. Anyway, since this year (well, April) was the 35th anniversary of the Apple IIc and because I also (finally) obtained an Apple IIc this year, I was hoping/planning to do a little write-up about the Apple IIc and include it in this year's issue, which I hope to release on December 31st if not sooner. If, *if*, I manage to finish the article in time, I'd like to include some accounts from other people who used the Apple IIc back when it first came out (I didn't) or those who still use one today, especially if you have something interesting you're doing with it these days. You'll get proper attribution (i.e., "John Smith of Cityname, Wherever says . . .") and that's about it. I'll send you a PDF copy of the issue if you want. I have 250-300 subscribers on my list and most never even download the issue, so you're not going to become Internet-famous or anything. So, if anyone's game, please let me know. Thanks!

    A tale of 3 Tibooks...

    I agree with you there. Seems it wouldn't be impossible to use tiny screws or even a slide-in fit to hold them in place. I feel fortunate that, when I got my now-ancient MacBook Pro, I bought a metal case with a padded interior that does a pretty good job of protecting the computer. It was supposed to protect the computer from a three foot drop, maybe more, and I don't recall ever dropping it from a height like that, but it has been knocked over or fallen over a couple times and the computer remained secure. The locks no longer work, and parts inside the lock are broken off so that ship has sailed completely, and the latches don't reliably work anymore, although they still manage to somewhat lock themselves shut on occasion, so I've had to resort to straps and Velcro to ensure it stays shut but otherwise it's still serviceable. The downside is that the manufacturer no longer makes such cases and all I've managed to find so far are fabric cases, sometimes with padding, but no secure, metal, interior-padded cases, which is definitely something I would want if I ever got a new laptop.
  3. Can't help but I can share in your misery. I remember a book long ago for programming in BASIC. You had to type in the code from the book-- no examples on floppy. And I remember this one program--I think it was something somewhat lengthy, maybe two to four pages in length--and I typed it all in and it wouldn't work. And I checked and re-checked for typos or any minor errors and still no go. As I recall, I never did get it to work.

    Discharging a CRT - video

    I'm guessing I may have gotten the information from this article: https://lowendmac.com/2007/the-truth-about-crts-and-shock-danger/ Says that: "If you want to minimize the chance of getting an unpleasant jolt, just let the thing sit overnight." But then there's this article that basically says "Run for your life!" http://www.peachpit.com/articles/article.aspx?p=759704&seqNum=2 I'm not claiming any expertise on any of this. After reading the first article, I'm a bit concerned now about recapping the power supply I have that needs to be recapped. After reading the second article, well, CRTs are scary again.

    040 Recommendations?

    Out of curiosity, what are 900s and 950s going for these days? Same here, except mine is a Q800. And I'm debating whether to put the PRAM battery in or just reset the clock each time. Or, possibly, rig up a dummy battery with the actual battery in a more accessible location, as someone did in another thread with a different machine.

    Macintosh SE Clock Battery Mod

    It's also easy to overlook and forget about something that lasts for ten years. I've had AA and AAA batteries leak in what seemed like under a year, so why take a chance? And I say that knowing I've probably got batteries leaking in different devices that I've forgotten about.

    Discharging a CRT - video

    Also, if memory serves, the longer the CRT sits disconnected from power, the more it discharges naturally. So, when possible, if you can let it sit for a few days or longer, there will be less of a charge to discharge, which makes it a little less scary when doing the actual discharge whether with a homemade tool or an official one.

    Mighty Jabba's Conquests

    What about a SCSI2SD? They have a PowerBook edition.
  9. I'm not going to get this done before the end of the year. I mean, I probably could, but I'd rather spend more time on it and do it right rather than rushed. Technically, I've already missed the 35th anniversary already, so I guess doing the article next year won't be a big deal. Anyway, that means if anyone else wants to participate, there's more time available. Don't have a definite date for a deadline but I'll post advance notice when I have a better idea.
  10. Can you use tape around the cracked areas to hold it together? I haven't glued together a PowerBook case but a week or two ago, I had to glue together the plastic casing for an old laminator. I needed to keep everything straight so it would go back together properly after the glue had dried. I used tape. On the outside of the plastic case, I cleaned any excess glue that was coming through the cracks and then taped directly over the cracks. Went around the cracks and everything I could tape in order to hold it together. Also, I folded over one edge of every piece of tape to create a pull tab that would make removal easier later. And that all worked. The glue dried and I was able to put the laminator back together without any problems. There is one crack that's not quite even so you can feel it from the outside. But this is also thicker plastic than a PowerBook case, so I probably would have done better to use stronger tape or, possibly, come up with some kind of metal bracing system to hold it all in place while the glue dried. But, it needed repair before the cracks got worse, and I didn't have time or the materials available to build a better bracing system.
  11. Are there dummy batteries available for the iBook G4 (or other PowerBook/iBook) models? I am presuming the battery in mine is dead. Doesn't seem to want to charge. Mind you, I only had the computer on for under ten minutes but still I would think maybe it would have gone from 0% to maybe 1% at least. In any event, seeing as it is a lithium battery anyway, I'd kind of prefer to get rid of it anyway. But, with the battery gone, there goes a foot as well, so it would be off-balance. So, I'm curious if some kind of dummy battery is available to fill the gap. If it wasn't lithium, I'd try disassembling it to see if just the outer cover, the part that matches the iBook, could be saved.
  12. The batteries are 18650. Still no idea of the size of the tri-point (y-type) screwdriver needed.
  13. Thanks. I may give it another shot at charging, but these lithium batteries always concern me. I did manage to find a disassembly video on YouTube and it appears the inside of the iBook G4 battery is just six cylindrical batteries. I've forgotten the battery number, but something like 18xxx, which are also apparently used in some flashlights. Knowing that, I'm more confident in being able to take it apart safely. Downside is that it has a pair of screws that requires some kind of tri-point screwdriver. I have a set of these special screwdriver heads for all these screwy shapes but, of course, one that would work for the screws on this battery is not among them.
  14. I think that will be okay so long as people indicate they are referring to the Apple IIc+. I can include a sidenote mentioning the differences between the original and later model. Might also allow me to work in a raisin reference which will tie into another article.
  15. Thanks to everyone so far. And, yes, a paragraph or two would be fine. And the more the merrier--I think (hope) people will be interested to see that there are still people running these machines today and how they are being used or even why people find them interesting. You can PM me responses too. And include an eMail address where I can send you the PDF of the final issue if you want to see it. And if you'd like to see a preview of the article beforehand, I can eMail that as well.
  16. Would it be possible/permissible for you to send a sample set of correct files (OS 6/7/8) and then a set of equivalent incorrect files (OS 9), probably in a StuffIt .sit file, so I/we can compare them under OS 6/7/8 and OS 9 to see what the issue might be? I'm vaguely remembering that OS 9 maybe did something with creator and file types and I'm wondering if perhaps that is the problem.
  17. Is there a thread around here dedicated to discussing emulation? I'm curious as to the best options these days. I know the ones I use probably won't run under macOS 10.14 so I will need to update to newer emulators one of these days.
  18. I'm a bit confused. Under OS 9, did the application no longer create the two text files? Or was it that the two text files it created were not, essentially, readable?
  19. That's a bit of a relief, actually, that someone else thinks that. Heck, I even tore off the Apple logo at one point because I didn't think the machine deserved to wear it. Which reminds me that one day I want to replace the missing/broken plastics on it to restore it to its original condition. And I'll likely keep it around but I wouldn't use it for any production needs. How does your setup work? Does the application on the computer feed the text files directly to the machine or do you create the text files from the application and then transfer them to the machine? I'm just curious if there is a possibility of using a translator to covert the text files from however OS 9 does them into a OS 8.6 or earlier text format. Maybe something like DataViz, if I'm getting the name right there. Or is running your program in emulation on a newer Mac a possibility?
  20. FWIW, a B&W G3 was the most unreliable Mac I have ever used. Maybe we were just unlucky enough to get one that happened to be somewhat of a Lemon rather than an Apple. I don't know. And I think some early models had a problem with the hard drive controller or something. Ours was replaced, as I recall, but the replacement didn't seem to fare much better. I don't remember all the problems we had with it, but it got so bad that I just kept the recovery CD in the CD drive so it was always readily available for when I needed it, which was fairly frequently. To be fair, the machine still runs but it doesn't get used that often and was eventually relegated to running one piece of equipment which is now obsolete. It still gets occasional use to open old files that cannot be opened on newer Macs. But I still wouldn't trust it as a production machine. Again, maybe we were just unlucky, so YMMV.
  21. The photo below is what the monitor screen looks like on my PowerMac 8600. Can anyone tell if that loos like an issue with the monitor itself or would it be with the PowerMac's video circuitry? Aside from not being able to make sense of the display, the computer appears to be working fine otherwise. (It's a server.) Of course, the easiest way to tell would be to try a different display on it, but where this PowerMac is located does not make that process easy. And if I need to go through all I need to to get at it, and if it's not the monitor, well, then I'd like to have the parts on hand to fix the PowerMac's video circuitry (capacitors?) so I can go ahead and fix it one way or the other. Thanks!

    Kendall's Collection and Finds!

    My guess is that would be an RF modulator to use a television set as a monitor. You'd connect to the antenna input on the television set and set it to channel 3 or 4 (set on the modulator) and the TV is a computer monitor.
  23. I don't think so because I wouldn't have had a reason to, on either point. It's the same monitor it's had for years. I remember doing something on it a couple months ago and the screen was fine but the last time I used it, maybe a month ago, the screen was as shown in the photo. It runs as a server 24/7 and I only turn the monitor on when I need to do something on it. But I don't disconnect the monitor at all. Just use the power button. And that's worked without issue for years. Pretty sure it is a 14" display. And I don't think I've ever even tried anything other than 640x480 on it. And I'm pretty sure all the monitors on the desk nearby that I might have used with it are all 640x480, but I don't recall trying to swap out monitors because I can't think of a reason why I would have and also because the way the machine is situated, it is a royal pain to even try. I have rebooted it to no effect. I am pretty sure I also tried shutting it down and then restarting, but I'll try that again this evening just to be sure.

    Brittle plastic OMG!

    I did. I think I had a thread on it here or posted in a thread, but that was a couple years ago when I first joined the forum. I had some broken pieces and was willing to use them to experiment. I *think* I tried the boiling water method and it didn't make the plastic any less brittle. I think I tried a second method too and that also didn't work. All I remember for certain is that nothing I tried worked. I still have plastic pieces here I can try stuff out on so if anyone has any other ideas to try, I'll give it a go, within reason.

    Rodime 45 Plus

    If it still has an odor after cleaning it, try sealing it in a box or plastic container with some activated charcoal.
