According to the datasheet the input voltage should be between 7 to 25 volt. 16v seems plausible.
However, choosing a capacitor with a lower ripple rating than the original can cause stress in the capacitor and make it fail again. So sometimes choosing the cheapest capacitor can break things...
Talking about cloud storage in System 7:
Here is a solution that 68kmla forum member bbraun made: http://www.synack.net/~bbraun/68khttpdisk.html
You just put a disk file on a web server, and mount it on your macintosh. A "cloud" storage for the old macs.. It's working quite nice.
I cannot...
If you install netatalk2 on a linux server, then you can set up a Appleshare pointing to that directory and connect to it in Chooser.
After you save the project on the macintosh you can use git locally on the linux server to commit/push. You can even login to the linux server with the macintosh...
I've looked for the P34 number on other places before, because the P34 sticker is a bit faded (3 almost looks like 8, but I'm sure it says 34. Everything else matches) so I wanted to be sure - but the P34 is nowhere to be found on the silkscreen.
I know the normal PowerCache cannot be used, but...
I'm no expert in this so I've waited for other to reply you, but here is my understanding of this:
They can work, but if the capacitor have a lot higher voltage rating than the original part then they can have trouble forming.
Lower voltage caps also have lower ESR, important in switching...
The original cap you replaced have cracked the same way as mine had. I replaced them with a KEMET PME271Y Series, DigiKey part number 399-5411-ND. These look the same as the originals. I have a euro mac plus, so these are rated 250VAC.
That reminds me of this thread: https://68kmla.org/forums/index.php?/topic/22511-mac-plus-tripping-home-electric-when-switched-on/
Recapping C33 and C36 fixed that issue for me (it tripped the fuse at home). When I opened it those two were cracked open. You probably want to order new ones, and...
In later, I think he mean the v6 board, because that another board design/code than the v4 board.

Old drives are on the end of their lifetime for several reasons, and will die eventually. Sometimes the oil around the ball bearing dry out over time, makes it harder and harder for the disk/motor to spin it up (sometimes you can use a small trick to boot it a last time by warming (with a hair...
Great project! I've been looking for a module like that myself just to bridge the vintage computers from their local switch to the wifi router. I'm currently using a raspberry pi with a wifi dongle, but it's a bit overkill and unreliable.
Why? What happened? I'm still looking at his website...
Did you check that the pins between the MOSFET and the other components have a connection? Maybe it burned up traces further behind, so check the surrounding components.
I got a Samsung 19" LCD Syncmaster 940BW from 2007 with a mac-to-vga dip switch adapter that works on the stock IIsi, so it will work with newer LCDs too.
I detached/pulled off the suction cup on the flyback transformer from the CRT tube on my Macintosh Plus to do some work on the motherboard. As I did that the pins inside the suction cup that connect it to the outer parts of the tube broke off when I pulled it out.
I've marked the pins with an...
The cd caddy slot opens when I put a caddy into it, and then the "CADDY LOADED" slot comes down, but it won't go up any more until i push it up by myself. I didn't see any switches, but maybe there is and it came loose when I opened it? Or the caps on the board attached to the front bezel board...
