    Mac IIci no video from motherboard, but I do get it from video card.

    Not really a huge deal, but it would be nice if I could get this fully functional. Just as the title says, I got a Mac IIci that came with a NuBus video card and an Apple branded IIci Catche Card. It needed a full recap, and the battery was dead (since removed). Other than that, it was just...

    Anyone know where to find a Surface Mount 25 MHz 68030 Processor?

    Have a Macintosh Iici that suffered a bit of damage to the processor. I managed to remove it. Only lost a bout 7 pads, 4 of which were no contact. With a little bit of luck, I think I can fix this. But I need a replacement. Any suggestions?

    Apple II (Not Plus) Board has Issues

    Recently got a Rev.2 Apple II board. Originally had AppleSoft ROMs, But the AutoStart had a bad pin (broke off) so I replaced them with an Integer set I had on a II+ board. The board boots to the Machine Monitor, and with a ROM switch card (AppleSoft onboard) in Slot 0, it will go to BASIC. I...

    Screen Cuts Out on my Macintosh Plus.

    Just as the title says. The screen goes black after about 5 to 10 minutes of use. Hitting it on the side with the analog board will bring it back for a few seconds at best but with diminishing returns every time. The good news is that the computer boots and loads an operating system. SCSI port...

    Quick Disk II 13/16 Sector Question

    I recently came across the 13 sector ROMs for a Disk II Controller Card and thought I'd give them a try. But before I do, I wanted to know if a 13 and 16 sector card can peacefully coexist on the same computer? Or would I need to designate a separate machine? (not my preferred solution since...

    Apple ][ (or ][ PLUS)?

    I recently got this board off of eBay and was wondering if it is what I think it is (i.e. an Apple ][ board and not a ][ Plus)? I think it is... At least it looks like one, but the date codes are from 79. The info I found on when the ][ was canceled is contradictory. Some say 79 while others...

    How do I do a horizontally scrolling sine wave in Applesoft BASIC?

    I tweaked this program from something I saw on the 8-bit Guy. Managed to get the wave to fill most of the screen, repeat, and end where it begins on the screen. However, I was wondering if I could get it to scroll horizontally across the screen? or draw from right to left? I don't know, I'm...

    Apple ][ Plus Graphical Glitches? Also Diagnostic software suggestions...

    I have a 48k Apple ][+ with a Z80 and ROM switch card (with original Apple ][ ROMs installed on the card), however, I do not have a language card at the moment. The computer works for the most part, but every so often, it gives me some graphical glitches. It's usually fine for the first hour or...

    Apple ][ Plus, Keyboard works (now) except Shift?

    Recently, I got an Apple ][ Plus in externally decent condition, but internally not so great (lots of dirt and debris, some corrosion on the motherboard). I've replaced the motherboard (tested to work, and boots). The old motherboard has no video signal whatsoever, no beep (did beep for a bit...

    Franklin Ace-1000 Beeps (sometimes) with a Garbage Screen

    Just picked up a Franklin ACE 1000 and I have an issue. The computer powers with a screen full of garbage (various random characters, many inverted, with a few random solid and checkered blocks mixed in), and will beep on power-up most of the time (every so often it's silent). Usually hitting...

    Problem //e board returned to life, but the joystick isn't working right?

    Overall, the computer boots, loads programs, passes self-test, and performs very well, but with one small exception. The joystick (a 9-pin CH Mach III I believe) isn't being recognized properly. The board has had some (rather sloppy) work done to it. All of the RAM sockets, as well as the...

    Mobius Legal Page Monitor Power issue?

    So I'm not sure if this is the right place to put this since the monitor is technically a Mac accessory, but I use it with my SE, so here it goes.   I have a Mobius branded legal page monitor that has sat in a storage unit for the past decade.  I finally pulled it out and hooked it up, but all...

    Broken Anode on a Mac SE Analog Board! Please Help!!!

    So I might be SOL here, but I'm going to ask anyway (and hope for a miracle).  In an attempt to replace the fan in my SE, I detached the anode from the CRT so I could work on the board.  Everything went well.  The new fan works.  However, when I was reattaching the CRT, the tip from one of the...

    Attempting to recap a Macintosh Classic Analog board and lost track

    I'm attempting to recap my Mac Classic's analog board and seem to have lost track of what goes where.  I'm not recapping the whole board just yet, only the ones that were obviously bulging or leaking for the moment as they're the ones that were the most obvious and problematic.  I've managed to...

    Attempting to recap my LC III and may have run into a problem

    So I'm trying to recap my LCIII motherboard.  I managed to remove all of the old capacitors, clean all the pads (all of which survived) but I just noticed that the resisters at R1 and R2 are missing, and one of the pads at R1 seems to have fallen off.  The pads on R2 are still there and I...

    Apple //e with horizontal bars

    I've been working on an Apple //e mother board for a while with no luck.  It worked when I got it, and all the ICs are socketed.  So I tried to use it to diagnose another malfunctioning board.  Unfortunately it didn't work, and when I reseated all the original ICs it stopped working all together...

    Apple 3.5 inch Unidisk Drive Analog Card Schematic/Repair Advice?

    So I have two Apple 3.5 inch Unidisk drives. One works fine, but the eject motor doesn't push the disc out all the way, but I can live with that. The other won't work at all. When I connect it to my //e and insert a boot disc, the light flashes, then nothing. I've tracked the issue to the analog...

    Macintosh LC Takes Forever to Boot

    So I have a Macintosh LC III (in an LC II case) that takes about 10 to 20 minutes to power up and boot.  Once it does, it seems to work fine, but if it goes more than a few hours without a power on, it just sits there spinning its fan for an increasingly extended period with nothing on the...

    Not a "Classic" Checkerboard Issue

    So I was recently given a Macintosh Classic (not a Classic II), and as one might expect, it will only give a checkerboard screen when powered.  All and all, it's a pretty common issue.  However, what's strange, is that the image isn't stable.  Upon powering, the screen flickers, and the...

    Macintosh SE Video Issue (Single Vertical Line)

    I'm having an issue with my Mac SE where the video goes to a single vertical line (1 pixel thick) after about 20 minutes of use. If I turn it off, and wait about 5 seconds, it comes back, but I really don't like switching it off like that (as it's really not good for the power supply). The...
