    550c Cap Issue?

    Thanks, Byrd. I'll inspect the connections. It could use a cleaning regardless, I'm sure. Its strange: after resetting the power manager, it will boot just fine providing that I don't plug in the SCSI cable. Let's see what we find inside...

    550c Cap Issue?

    Could this be a capacitor issue? My 550c was running fine. I ran Apple Personal Diagnostics and no errors were reported. I shut down, plugged in my AppleCD 600 (with the Apple-branded PowerBook SCSI cable) and rebooted. All is fine- the computer starts, CD comes right up on the desktop, we're good to go. But when I reboot in this configuration, I get a Type 10 error on a few boots and Bus Error on others. The same problems after I removed the SCSI plug. Then...death chimes. I pulled all power, waited 5 minutes, reset the power manager, and booted without the SCSI cable. Successful boot. Plugging it again caused the same series of problematic events. When I plugged in the SCSI cable to the powered-off machine, the speakers crackled. This makes me think that perhaps a capacitor somewhere along the line, is weak. I have not yet taken it apart to inspect. For another data point, the same drive and cable work fine on my IIci. I eager await the collective wisdom. Poor little machine

    PB180c fails to start

    Two (or three) procedures come to mind: 1) PRAM reset (although it could be moot if you don't get the chime at all) 2) Power manager reset type 1: Remove all power, wait 3-5 minutes, then connect AC but it sounds like the second mode might be more useful. 3) With a paperclip, hold down both the Reset and Interrupt buttons on the rear for 5-10 seconds. With all power sources removed, maybe the manager needs a reset.

    IIci is...ALIVE

    insaneboy, I'm sorry that I didn't see this sooner. Wow! That's quite a nicely spec'd IIci. Do you still have it? I have a RasterOPS 24XLTV for it along with an accelerated Radius card. I'm curious to see what dual screen 7.6 is like although one of the Apple monitors has lost its center focus. By the by, I'm in Portland as well. Boston transplant as of 10/19 : )

    2400c Intermittent Backlight

    A half-dead battery is probably what the PRAM batt. has become in both machines. Thank you for your help. I'll be able to get it out next weekend and I'll post how it goes.

    2400c Intermittent Backlight

    Ah! Thank you, Jeremy. Now that you mention it, it does act odd when powered for the first time in a while. It will boot instantly when power is supplied (battery or AC) without pressing the power button. The PRAM battery is in a tough spot to get to. Do you know if this is a machine that requires its presence to power on?
  7. On my quest to fix all the Macs on my list, I've come to my two 2400c PowerBooks with the same issue, intermittent backlight. Every other cold boot or wake from sleep results in the display functioning (with direct light I can see the display) but without backlight. I've run through all the prescribed resets to no avail. I have not encountered the GLOD (green light of death) from the sleep indicator. Aside from this backlight issue, they run normally. When it does come on, its bright without any unusual buzzing or humming. This happens on battery power (those Japanese cells still provide 40 minutes of power) as well as on AC and AC w/o battery. To the more knowledgeable, does this sound capacitor related? I am considering sending them in to be recapped but as this model is notoriously difficult to open up, I'm open to suggestions.
  8. Thank you, trag. With the board out, it will be easy to check for the soldered chips. Much appreciated! I don't think it is an unusual early model. It was a clean eBay find when platinum Macs didn't command an inflated sum. I have a Sonnet G3 for it. Should the cache DIMM also be missing, I assume that it won't be needed with said upgrade?
  9. With the arrival of a SCSI2SD, my 8500 is ready to be put back together except for one thing...I seem to have misplaced the ROM SIMM. I did take it apart three years ago and stalled out on the project, but I am kicking myself for misplacing it. As these cases are a bear to fiddle with, I haven't tested it without the SIMM. I have read that various PCI PowerMacs won't boot without it (makes sense). Does it indeed work, sans SIMM? If not, does anyone have a spare lying around that they would be willing to part with?

    IIci is...ALIVE

    Thank you, elbaroni. Well said. I suppose that holding your breath waiting to hear the right noises is part of the conquest fun. At least when the problem is finally solved. Its good to be back. I hope to keep my 68k momentum going.

    IIci is...ALIVE

    First of all, its wonderful to see 68kMLA alive and well. It has been a little over four years since I last posted/visited. I accumulated far too many 68k & PPC projects than I had time for but as of late, I'm making progress. Its good to be back. On to the abridged IIci story. In 2008, I won a IIci on eBay and immediately encountered multiple failed caps. When I finally got around to sending the board off for repair, there was too much going on to really focus on it. The perfectionist in me didn't want to set it up until I had all my project parts in: accelerated graphics board, DayStar Trubo 601 (or similar), maxed out RAM, and operable floppy. I accumulated these parts over time but never sat down to get the darn thing going. I even found a lovely Macintosh Color Display and minty fresh AEKII. Final installation wasn't meant to be. I moved across the country and my kit sat until four days ago. A snowstorm created a long weekend and I decided to slay the perfectionist. I had enough parts, lets go! Assembled the setup, plugged it in, POST chime.....death chime. Re-seat the RAM. Nothing. Shuffle it around. Nothing. Disappointment and aching fingers? Affirmative. I was so disappointing. Almost 12 years of ownership and I had never turned it on until now. I let it sit and walked away for a bit. It occurred to me that 4 SIMMs looked old and 4 looked newer. Maybe the newer SIMMs were either incorrect or failed. I'm not sure why I didn't think that maybe the older ones were the issue, but I removed the newer ones and put the older Samsung and NEC modules in Bank B. Voila. POST chime. I froze, waiting for the sound of failure. Absolute sure it would pour out of the little speaker. Nothing but the hum and clicks of a SCSI drive waking up. It worked! I turned on the monitor and has the image came into focus, bootup completed and played a sound clip set by the original owner that could not have been more perfect, "I'm aaaaliiiveee. (From the sci-fi horror flick, Demon Seed.) Could not have been more appropriate. That little quirk really set the emotional stage for this machine..cheeky. The floppy still doesn't work, but I'm sure I'll find out how to fix it here. No 601 until that works but thank to the Floppy Emu, I backed up that sound clip. Anyway, that's my contribution to Conquests : ) alive.mov alive.mov

    New (to me) 180c, Advice on Rehab

    Thanks again, rsolber. I'll get in touch with Uniserver. techknight, I believe it. Silly thin seems to have moved from fashion models to consumer computers. Having seen how thin the new Mac laptops are, I'm not surprised they are all glued together. Bleck, I'll take a serviceable ThinkPad from Big Blue anyday. If only they could run 7.6.1 . I am so looking forward to getting this little 180c ready for daily use.

    New (to me) 180c, Advice on Rehab

    Thanks, rsolberg. That's right, I almost forgot. A SLC card would fit the need perfectly. Handy that they tend to come in sizes workable with System 7. As for board recapping and replacing backlights, do you know of anyone around here who offers that service?

    New (to me) 180c, Advice on Rehab

    Robbing my 180 had come to mind but I couldn't bring myself to do it. It does make sense, since I can't use it without the external monitor. As for the Artimix: I didn't know about those. I checked out their specs on eBay- an interesting card. You would recommend that over the CF AztecMonster? The appeal of the Aztec set up for me is that I can format the CF card in my 3400c whereas my only SD card reader is in a ThinkPad running Linux. On this note, how well does VM work with any of these solid state setups? I'd like to use Ram Doubler and I really only run Claris, Word, and some games without replacing the card every few years. Perhaps the rewrites are that numerous with my usual workload.
  15. My much loved 180 has succumb to tunnel vision and is now used with an external display. Still wanting to take a 1xx around with me, I was given a very nice 180c with a few goodies: system disks, VST ThinPack, and a snazzy case. The 180c is in nice condition save for an annoying trackball but at least it has a port door. After a few disappointments with some 68k portables, I really want this 'Book to be a reliable travel machine. The SCSI drive is tiny and noisy, so I think a CF adaptor is in its future. Any recommendation on the best CF speed rating? I cleaned the trackball innards but it feels like there is a physical problem. Is the solution only a new mouse/keyboard unit? No cracks that I can see in the housing or gunk in the springs. VST ThinPack- salvageable cells? I haven't plugged it in yet but I also know very little about them. I'm assuming its NiMH. I don't have the manual to know for how long to leave it plugged in, but I'm assuming the little LED will tell me. Recapping- No apparent problems so far save for a small speaker pop before an alert sound. Would it be prudent to recap anyway due to age? I have no confidence (or time) to recap myself. Are there any members here who run a save-the-mobo service? Same for replacing the backlight? Lastly, the LCD housing is still quite snug but the left side is starting to pull away. Is there a better solution than glue? I can see the LCD pull away from the front bezel just slightly when gently closing the lid. I haven't done a tear down just yet. I am still basking in the newness and starting to take stock of what needs to be done.
