    Mac plus, blank screen after recap

    well, at least I now know the flyback and actual screen if fine.  I'm not going to look a gift horse in the mouth at this point and just roll with it for now.

    Mac plus, blank screen after recap

    Ok so, this is going to sound crazy, but it started working. I set it up again, turned off the lights to see the area behind the yoke and flipped the switch.  I saw a slight warm glow and then a bright one from the front.  The damn mother f-er came to life and it looks damn near perfect.  I had...

    Mac plus, blank screen after recap

    Got the replacement for U2 today.  replaced it.  made no difference.  Still 100% black screen.  Am I at the point where I need to replace the flyback?  I've resoldered it and all the connectors.  I tested the voltage at the logic board.  the voltages are BANG ON PERFECT.  That was as far as I...

    Mac plus, blank screen after recap

    So I had some time today.  Completely re soldered the connectors.  Made no difference.  I measured the resistance of the connector, all came up at zero ohms.  (at least less than .01 ohms)  went ahead and recapped the logic board.  SO much easier than the socket A board I also did today.   next...

    Mac plus, blank screen after recap

    @juror22 I'll check the harness.  There is no obvious signs to it NOT working, but I guess there isn't any harm in trying now.   @unity I haven't messed with the connections on the logic board.  That board is in pristine condition.  I will go ahead and re-flow and recap the logic board as...

    Yes. Cold joints was the first thing I checked. I resoldered both connectors. Sorry I didn't mention it first.

    Mac plus, blank screen after recap

    Title tells 99% of the story.  Got a mac plus off craigslist for $40, no worky.  recapped it, still no worky for the same reason.  popped in a disk, it reads it and acts like it boots.  Can even apple-E to get the disk back. Looking around, I come across the "Macintosh repair and upgrade...

    Vintage Mac as Crypto-currency Tool

    I mean if you REALLY want to trust the machine making your keys/wallet/whatever you can always do the math by hand.  No calculators, just an abacus or slide rule and a bunch of paper. Granted you would probably want to have a bonfire afterwards, should be fun!

    Vintage Mac as Crypto-currency Tool

    I have hardware that supports virtualization and I use it often.  I did play with bitcoin for a bit, In fact I used it to buy an ati 7970 for xfire goodness.  I can setup a small XP or win7 box, encrypt the drive image, and have better security than an old mac in my mind.  Not going too far into...

    A $40 mac plus

    Reading about others analog board problems, it seems everyone is hating on J1 and C1.  Well I took another look, and I had forgotten to plug J1 back in. Didn't matter, still black screen.  So I'm going to re-cap this thing. any thoughts on this guy to replace C1...

    A $40 mac plus

    I re-flowed it with some new solder.  I think I saw 3 ish bad joints on that large cable and fixed them, but they weren't even that bad.  I never realized you had to do a complete wick and replace.  I did check all the connections, and all the trannies/diodes. I can hear the flyback kick on for...

    A $40 mac plus

    Snagged this off craigslist:   This thing is GRUNGY.  Like it was stored in a barn.  Long story short, the seller said it chimed, but no video.  I got it and it didn't even do that.  Tore it apart and there were cold solder joints on the analog board going to the logic board.  5 minutes with...

    snagged a G3 desktop, now what?

    I know mine does.  The machine is very unreliable without it.  Once its started its fine.  Maybe needs a re-cap.   :p

    snagged a G3 desktop, now what?

    Also, please excuse the rambling nature of the post, I just finished a 60 hour work week.  I'm tired and my head hurts.

    snagged a G3 desktop, now what?

    Few weeks ago now, I found someone selling a G3 beige desktop for $15.  Turns out the damn thing was practically new.  Problem is, I don't really now how to move forward with this machine, (been mulling it over for weeks) so I figured I might as well ask the peanut gallery.  ;)  Don't worry...

    PAS16 & 840av, strange errors

    recently bought a boxed PAS16 for my 840av.  Mostly because it was cheap, and on the off chance the audio would be cleaner and easier to record. Long story short, it does work, but has some weird quirks, and I was hoping someone here had some insight.   #1:  There is quite a bit of popping and...
