    Help Color Classic - Won't Power On

    First question is if you remove the motherboard and flick the power switch does the machine sound like its trying to start up (fan turns on, screen degausses, hard drive starts)? I have had CC analog boards that packed up with no outward signs of trouble.

    Baroni’s Collection

    And finally got to the Laserwriter I. Don’t know yet if it’s a plain I or a plus (or what version of the plus) but it looks super clean inside apart from one spider corpse. I’ve ordered a new toner cartridge because the foam on the old one has liquidated. Turned it on and it made all the right noises, identified correctly that there’s no paper (although there is a paper tray!), but I turned it off before the green light stopped flashing. Dunno about that serial port though. Still, found a db9 appletalk kit for $5 which is cool. It and the toner are en route.
  6. Hi All, I recently acquired a color classic from a seller, Originally the computer was not booting so i recapped the motherboard and it came to life. about a week later the computer would not boot from the hard drive and now it will not boot at all. (No LED or anything)I have left it plugged in the wall for 24 hours and tried again but still no sign of life. I have pulled it apart and inpected the analogue board but can not see any bulging capacitors but there was alot of dust. Can dust short these out and make them unusable? Please help

    Mac 128k Keyboard Recapping - 1uf 63V

    You are correct. On the machines I have re-capped for other people, I have always left a label that states that I did the job, and what date it was done.
  8. @LaPorta What I do is use a thick black Sharpie pen to handwrite the replacement date clearly on one of the big, easily noticeable caps, and that serves as a note to me (or those two whom I sell something) that ALL the caps were replaced on that date. Paper notes get lost but a pen-mark on the cap won't go away.

    Mac 128k Keyboard Recapping - 1uf 63V

    Indeed, I have made notes on when either myself or whoever later takes on my Macs (hopefully one of my kids) will need to replace the ones I have replaced.
  10. Here's a photo of my recapped IIgs keyboard, and note the hot glue around the ADB connectors that I added is important to prevent broken solder joints: And here's a photo of the Apple Mouse G5431 with stock capacitors (3pcs). Width and Height of replacement caps is a very important consideration because there's not a lot of space. Suffice it to say, if you've been having tracking issues even though your rollers are clean, it could be the caps! Normally you want to spec Tantalum caps higher than electrolytics to avoid a fiery explosion in the event of over-voltage, but ADB supplies only 5V. So you could safely use 16V radial dipped tantalums without problem, and at that voltage rating they should fit fine.

    You need the adapter as well.

    How bad is the damage?

    Totally fixable. Looks like it wasn’t sitting too long with the gunk doing its thing at eating away on the board. Lets hope the RTC chip is still good, getting replacements for those is an issue and requires another Mac as donor.

    Mac 128k Keyboard Recapping - 1uf 63V

    That's good to note (that you had fixed a keyboard by replacing a cap - I'll keep that in mind if I see a similar issue) On the longevity of the caps though - if you're putting in caps that last 30, 40 years you're taking away the excitement of recapping from the next generation!

    How bad is the damage?

    Honestly? Not that bad, classic 1 boards are the only boards I've ever been able to fully resurrect. You need to disorder the battery holder and clean the junk. The other part of this, is that almost every Classic 1 has the Maxell Bomb. It seems that 1991 was the worst year for leaking Maxell batteries, and since most classic 1s were made in 1991 this is a real problem.

    Help with portrait / full page displays

    Check out the Radius Q&A, there were several flavors of the TPD with different interfaces. http://archive.retro.co.za/mirrors/68000/www.vintagemacworld.com/radiusmain.html

    How bad is the damage?

    Have a Classic I recently acquired. It will chime 1 out of every handful of times you attempt to power it on, otherwise it just acted like it had no power. When it did boot the video would cut out intermittently but ultimately I would get a solid picture and it would blink the ? disk. Opened it up and found the carnage below. Is this worth a repair attempt? Aside from the chassis damage, looks like just a few components were damaged that could be replaced, D1, D2, C70. Might as well recap while I'm in there. No visible damage on the analog board. Since it did boot, I'm hopeful that component replacement will yield positive results, however, this would be my first major repair like this on a Mac and I'm looking for opinions from those who have more experience with these repairs to chime in. Is the damage bad enough to scrap the board or would a repair work? Also, that leak from the CRT, what is that?? Thanks all.

    3D Print Replica HD 20 SC Enclosure?

    @PotatoFi wow, that’s looking good! Can’t wait to see the update.

    3D Print Replica HD 20 SC Enclosure?

    Ok, I've finally had some time to sit down and work on this project! Here's where the model is at right now: So far, it's basically just a shell, but it is dimensionally accurate. What's not done is all interior drawing, the back, and rounded corners. So there's quite a bit left, but the basic shape is there. One thing I realized immediately on getting the hard drive is that it's deeper than the base of a Macintosh. That was a pretty fatal blow to printing it on my printer... I knew it was going to be tight, but not this tight. Here's a view in my slicer application, from the bottom so you can see the size of the print bed. Still, doing a "shallower" version on my printer is still a possibility, as we're good on width - just not depth. I'll keep working on things. 1/4 scale version printing now, will post an update tonight or tomorrow morning.

    SE/30 with Vertical Pinstripes

    It could also be a stuck input on UE8. But as said I would check the address lines first.
  20. I also discovered a card for the SE/30 that has a label on it that says PDS/30 dual page display; it has the same two row 5 over 4 video connector.

    Monitor Solution for Macintosh IIci?

    They may THINK the power switch is broken. Don't be too hasty. The power switch is ignored if there's no video signal coming into the monitor. Automatic sleep mode. I've pressed my like new monitor's button a few times going WTH?! And then turned on the computer and it instantly lit up. Too smart for it's own good.
  22. Going through all my CRT's to see what works, I don't quite understand what is necessary to use the portrait and full page displays. I've never had the opportunity to use any of the portrait / full page displays before, so I don't quite know what is necessary. I do have two Radius FPD90 Nubus cards, but they have a standard Mac video connector one it, nothing like the ones on these displays. I have the following (see pictures): Macintosh Portrait Display This one has a 13w3 connector. Those cables are in unicorn territory, like this one. That one says it is for a two page display, but looks like it connects a standard Mac monitor cable type to the 13w3 type. Would any old card work to drive a portrait as long as it can put out the correct resolution? I also see Sun 13w3 to VGA adapters. I'm wondering if I might go Mac to VGA to 13w3 with that adapter. Anyone tried this? Radius full page displays I have tow and they both appear to have what looks like EGA type connectors (the predecessor to VGA if my memory serves me). One has a male connector, the other female; what is up with that inconsistency? What the heck is that? Is the the full page display card connector? Will a standard serial cable of that type work? I have some but I believe they are just serial cables. I do have one card labeled just Radius Full Page Display that has one of these connectors. Radius Full Page Display/gs You can't see it well in the picture (too dark) but the connector appears to be idential to a VGA connector. What kind of card does this need? What can get me from a standard Mac Can anyone help?
  23. Hi everyone, I have been having an issue with my PT Pro (I guess it was always an issue, I just never used the drives much). I am unable to use the internal CD reader and user-installed CD writer properly. With the Apple CD/DVD driver under OS 8.6, I cannot insert a CD and have it mount. If I start with the CD in the drive, the disc will appear, but then I cannot eject it. Upon attempting to eject, I get an error -50 and the disc will not eject. If I try to use instead FWB Toolkit, I get an error at startup that the FWB Toolkit cannot load because another driver is running the drives...but this is after I have disabled the Apple driver with the Extensions Manager. I am at a loss here as to why this is. I would normally say hardware error, but the same thing happens to both drives.

    SE/30 with Vertical Pinstripes

    Ah... Well then check connectivity on the address lines going to the video address muxes (UA8 to UD8) One of them will be broken. It’s also possible one of the muxes itself has a stuck input or output but I’d start checking for connectivity.

    Early Macintosh Plus

    This is a Mac Plus I found at an antique store in 2015 for $60. Wasn’t the steal of the century, but I had a platinum Plus, so I really wanted this beige one. Turns out, it was a very early product unit! I just recently discovered the serial decoder on myoldmac.net, and it is indeed an early one like I thought: I’d get some inside shots, but I have misplaced my tool. I do remember the CRT had a late 1985 manufacture date on it, which told me it had to be a pretty early Plus. It is also fully-stock with the original 1MB even. I don’t plan on upgrading it, since my platinum Plus already has 4MB. Just thought I’d share this!
