Have you checked the plug in jack on the logic board? True this section fails in the Analog Board a lot, but it also fails in the logic board too. Just desolder, clean up and resolder the connection.
The system does need to be recapped. There are a couple of large Axial caps that do need replacing. That's a given. I have a IIfx, and it needed a recap even though 905% of the board had Tantalum caps on it, there was 3 of those #$&%@!! bleeding caps on the power supply area of the IIfx...
The change happened after System 7 (7.1?) came out because you can boot System 6 on an LC on a floppy and think nothing of it. But Boot System 7 from a floppy and you will be pulling your hairs out! I got 5 LC’s, 3 are Dual Floppy but 1 is actually has dual floppy drives, the other two have a...
If this were a 6kK, I can tell you – Yes and No; Yes, they will work; No, not at the original speed. This is because the CPU Clock is external to the CPU. Case in point: The LCIII, there are 2 kinds by apple – the 25MHz and the 33MHz. The only difference between the two is a couple of jumper...
Which OS are you using? Usually, the desktop files (2 for System 6 and I believe 3 for System 7) are on the main root directory of the hard drive.
Diskcopy on the Mac usually copies visible and invisible files from drive to drive. Programs like Utility Dog can find invisible and make them...
Lets deal with the floppy drive first. Its time to open her up and relube her parts. Mechanically they are the same as a Mac Drive with some minor differences to the Ejection system. Just take your time in doing it. That should fix things for you.
Sorry for the confusion then.
TEAC was not the only one to have this. TDK and Panasonic cassettes had them as well. In a regular cassette tape there was a Mylar/graphite sheet between the roll of tape and the outside case so the tape can slide inside the case without binding or wearing. These...
The speed of cassette tape and the speed of reel to reel are different, the reel to reel is faster for a higher frequency response (bandwidth). So pulling out the tape of the cassette and put it on the reel to reel, it will be played faster on the reel to reel, making it impossible for the Apple...
When the DISK ][ card fails, it is one of the 74LS Chips. Replace all three and most of the time it will fix it. They blow out because somebody put the ribbon cable on the header wrong, which blows a chip or two. This will fix 95% of all Apple II drive issues.
Once in a while then they blow the...
That's funny, Anonymous Freak, as they all have the same keyboard, just the placement of the connector and ribbon is different. It depends on how broken down the rubber in the keyboard is. You can swap out the Mylar sheets to get the best keyboard out of the one you want to use the most...
The lubrication on the Floppy Drive has dried out and hardened. That is a simple fix of taking apart the floppy drive and relubing it. The forum's Wiki Section has instructions on how to do it:

FloppyEmu is a nice alternative. It can act as a...
Found this on EBay.
But maybe somebody has a dead 512Ke/Plus and can sell you their ROMs...

Not to throw anyone a curve ball, but I found this - a 68K Card for the Apple II! OK, one is not going to run Mac Software on their Apple II with it; it was for CP\M-68K similar to the Z80 cards running CP\M on the Apple II.
But, it was the board schematics AND board layout for the card! So one...
