  1. Hey @dan.dem thanks for your help. I'm pretty sure I've definitively identified the problem as corrupt files due to a version of the SCSI2SD v6 firmware that is incompatible with the PowerBook 540 series. Backing the firmware down to 6.2.5 and everything works perfectly. But with newer versions of the firmware, I can't copy to the device, and files copies from it are corrupt with the above problem if they launch at all. Once I downgraded, the same files copied over worked fine.
  2. Yes, turns out one did in fact have a bent pin, good call. The other had a keyboard cable that had loosened up such that the power button wasn't doing anything. both are working now.
  3. Hi, love your site, especially your scan collection. I noticed that there's a missing link in the Macintosh technical documentation series:

    fej8.jpg.56120f5f4cde6131d4233c08cdf33ff

    Macintosh Family Hardware Reference sits between Technical Introduction to the Macintosh Family and where Guide to the Macintosh Family Hardware would be in a more recent version of the roadmap which you host on your site already an I couldn't a PDF anywhere online.

     

    I really want to keep mine bound, but I'd love to PayPal a donation of $8.50 toward the purchase of one. Are you in the USA? I'm poor as a church mouse, but positive I can get a couple up others to donate the remainder of the cost via PM if you'd like?

     

    https://www.amazon.com/Macintosh-family-hardware-reference $28.50

     

    It could prove most helpful in the Reverse Engineering the Macintosh SE PCB & Custom Chips for 1:1 reproduction thread and that gang will surely chip in the remainder.

    On a side note, I've always wondered if a formatted text only version of the MacUser and Macworld could be done sans the artwork. One big PDF of each (both?) series in that format would be wonderful for keyword searching info on specific products. Then go to the artwork encumbered versions of specific issues for illustrations, historical context and such. I'd started a listing of the yearly indexes, but they are hard to locate, varying from year to year and seemingly missing from some years.

     

    Thanks so much for your efforts, especially hosting Gamba2, love your breakout of specific articles!

      Hey JT,

       

      No worries, I am happy to cover this for the team.  I just ordered a copy. 

       

      In terms of text only MacUser and MacWorld, I could probably hack together a python or perl script with some pdf libraries to extract the text.  But I'm not sure about formatting.  Hmm.  The PDF files are first and foremost images, which text added after the fact via OCR.  So if you remove the images, you would just have text left, unformatted.  . 

       

      What I typically do is just search using spotlight on my Mac at the top level where I have all my magazines and books, all of which have been OCR'd.  That brings up matches and shows what file they came from which is how I typically find things.

       

      Separate text files could be also used with grep, for a little more search control than spotlight. 

       

      What do you think?

      Thanks much, Peter. I'm sure the SE builders will really appreciate your contribution. Each volume builds upon the last and hopefully there are a lot of cues in MFHR to better aid cryptological methods for deducing and recreating the PALs/ASICs as needed.

       

      About the search thing, using reader an issue at a time is as far as I've gotten, I'll have to research Searchlight. [:I]  Unformatted text from each complete series would probably be workable enough for down and dirty research purposes in terms of issue/page spelunking.

       

      I've always wanted a good reason to learn to GREP something. :lol:

       

      BTW, I just found/remembered that the link to Ports_Pinouts.PDF in your (all?) Gamba2 hosting pulls up a DOA Apple page. Directly hosting it along with the books on the development tree would be much appreciated, maybe redirecting that link in Gamba too? I imagine it's out there, but didn't find it in a few seconds of search today. I have it if you can't easily scare it up.

       

      again, really love your site,

      Hi again and happy Thanksgiving!

       

      Was musing and now rationally thinking about the Image/text thing regarding text extraction from magazine pages within a PDF.

       

      As a longtime AI user, I've been opening development book PDFs for grabbing artwork and text since they became available. Text characters, lines and paragraphs are objects with their own coordinates on the baseline page grid. My guess is that the OCR'd text is much the same, it's probably an overlay, invisible text objects located within page coordinates. Can't imagine it's not in its own layer across every graphical page layer and fully formatted within the PDF, page returns and all. Can't open a volume file using AI 9.02 on my QS, likely due to file size. It normally asks me which page I want to open, which is a guessing game as the intro/contents pages in Roman numerals count as pages.

       

      I haven't got any graphics programs set up since the move to X. Nothing appealed to me about upgrades to my apps and X was HORRIBLE when I tried it at first release, still haven't tried it on my 12" AlBook, heading right to and still loving my OS9 bubble.

       

      If you're not set up with graphic design menagerie (sounds like you're a programmer?) bounce this notion off your Photoshop guy to test the theory. If it's correct, I imagine it would be a lot more productive to tweak the GIMP as an automated paged text extraction engine than working within the bars of Adobe'sproprietary prison?

  4. Wonderful! I just bought two. Is it against forum rules to post a link to your own stuff for sale on eBay? Can I post it for you?
  5. @AlpineRaven somewhat stale thread but I've been playing around with a couple of 540c's lately and am definitely having weirdness with my SCSI2SD v6. The firmware seems problematic. I am back to ver 6.2.5 as with any newer version I have issues copying files to/from the v6. One PB has the 550c processor in it, one does not. The one that doesn't has an internal PowerBook edition SCSI2SD v5.0, other other one has a spinner hard drive. Your symptoms are not quite the same as mine, but perhaps if you haven't figured this out already it is something to try, either upgrading or down
  6. @360alaska I'm also looking for SCSI2SD solutions for PowerBooks. You going to make some of your adapters available for purchase?
  7. Er, scratch that. 6.3.2 still has issues with the PowerBook 540c. Grrr.
  8. I think that the SCSI2SD issues are a problem with the v6 firmware. I was previously having problems with the v6 and another 540c and had identified it to be a v6 firmware issue that was introduced after firmware version 6.2.5 (which worked). I ran into the same issue today on another 540c and a v6. I upgraded the v6 to firmware version 6.3.2 and it solved the issue. I'm going to go back and test this same update with the other 540c and v6 combo.
  9. @Crutch yea I got the error first without virtual memory turned on, and I've since swapped out a different hard rive. I was able to copy the same executable to the machine via appleshare and it worked fine, so I think the SCSI2SD have issues unfortunately and is corrupting files that are on it. Yea, I've been looking for a full 040 for a while. There's been discussion back and forth about whether it really makes any difference, and the reality is probably not, but there is just something about having a machine maxed out as far as it can go that appeals to me. And the price was
  10. I think you are right. There were more than one but they were all off the SCSI2SD device. I think that device for some reason isn't working properly and is corrupting files, as well as the inability to write to it.
  11. Example of the video glitching. IMG_5327.mov
  12. Ah, must be a flakey LCD cable. I switch to greyscale and it had a distinct greenish tint. I went to take a picture with my phone and moved the screen a bit and the tint disappeared. Now the screen is periodically glitching. The SCSI2SD problem is strange. I ran into the same problem with another 540c that had an internal SCSI2SD and with some versions of firmware for the internal SCSI2SD it would make it impossible to write to the external one without issues. In this case, I can copy from the external one just fine, but when I try to write, I get a disk error. On
  13. Yea, I think you are on to something there. I popped in another hard drive and it had the same version number of Fetch on it which ran fine. There may be a wrinkle in my new 550c board. The video is showing some odd coloring with that processor board in. I wonder, does the processor board also have the video chip(s) on it? Now for some reason I can't write to an external SCSI2SD v6; I wanted to copy the version of fetch from the one hard drive to the other and swap them again. I've been bumping up against these strange issues with SCSI2SD's lately where they won't
  14. I tried swapping out the 16MB board for an 8MB one to see if that might be the issue and nothing changed. I tried booting with extensions disabled, no change. I tried swapping the processor board for another (that sweet full 68040 I picked up last week ... HELLO 550c mod), no change. Doesn't seem to be a hardware thing. I'm going to try swapping a different drive in.
  15. Is there some kind of memory test I can do? Not sure if this model tests the memory on startup or not.
