It looks as though all the soot is originating around the flyback. The soot is mainly on the flyback, the flyback cable and the back of the CRT where the anode cap is. The clear anode cap and the the cap at the other end of the wire leading into the flyback is kind of "wet" with an oily feel...
This poor thing has been in storage since the early 90s. I was gonna use it as a donor Mac but it turns out I don't need any parts from it. So, I decided to try and resurrect it.
I plugged it in with my Floppy EMU to try a boot and just got clicking from the PSU (not surprised). I started...
Can you post a link to those tabbed cells? Especially if you have tried them and they work :) I have a blueberry and a Tangerine I'd like to get working off the battery.
I re-soldered all the bad joints on the PSU and it fired right up! Nice and bright!
I bought a X-Tronic soldering station and some no-clean flux and some wick. That flux is super sticky. Alcohol doesn't do a great job cleaning it off the board, is there something that works better?
All the caps...
I found a few cracks in the solder where the cable attaches to the side of the CRT. And there are brown stains at C1. But C1 is one of the black and white caps that don't leak. Maybe it's just flux?
Josh and Cheese, that sounds like sage advice. Now I gotta find someone who can reflow solder joints. I've never done it and don't have the equipment. I would love to learn on an old radio or something but I don't want to experiment on a Mac that's this important to me.
To further validate your...
I get around 10v from pin 7 and 4v from pin 6. I left it for a few minutes and it actually booted from a floppy!
I still need to get it fixed though because it's not reliable.
Does it sound like a cap issue or maybe the flyback is bad? It looks a little corroded.
If there's any Mac I want in...
I have my original Mac Plus that I bought in 1986. It's been in storage for about a year. I just took it out and tried to boot it and got a beep and then nothing. I have a 6.0.8 boot floppy in the drive but then I hooked up my Floppy Emu and it lights up but keeps going in to self test mode...
I just fired up 2 of my LCII's to discover both power supplies are being wonky. One of them does nothing and the other one makes the speaker hum and lights up the screen but won't chime or spin the HD.
I have 2 LCII's with dead power supplies as well :(
One of them does nothing, the other one displays a blank screen and the speaker hums, no fan or HD activity though.
I just fired up my IIci after about a year in storage (climate controlled). I'm noticing the sound is barely audible. I have it cranked all the way up and can just barely hear it. The startup chime is nice and loud though. Any suggestions what to check for?
Hi,
I have a 17" Studio Display with a DVI to ADC adapter. It works fine on my 2015 Macbook Pro plugged into the HDMI port. I'm using a DVI to HDMI converter. When I plug it in to my Retro Pi it gets no signal at all. The monitor power comes on when the Pi turns on so I know its recognizing it...
That's a pretty pragmatic set of rules. Usually I like to go with the system version it came in the box with just for authenticity. I put these rules in my Apple Notes for reference, Thanks!
You could use a 2 or 3 second sample and play the full sample for each disk access, even it it were just a split second. If the files were a couple hundred Megs and it took say 10 seconds, you could play the sample 3 times or as many times as would fill the transfer time.I don't think the sound...
I just went with 7 pro (7.1.1). That's what the cc came with anyway. If I can find a logic board I'll make it a mystic. 640x 480 sounds pretty enticing and will allow me to play better games on it.
