Apple II

I'm in the midst of reviving my old Apple ][+ clone, and while waiting for some replacement components to get the computer going I thought I'd look into the software side of things and try to refresh my knowledge of how to use my (5.25") floppies and transfer files and programs to/from other platforms (most notably a current Mac, or an Atari STe in case a serial port is needed which my Mac doesn't have).

I'm sure these things get asked all the time, so I'm wondering if there's a FAQ, an online guide or something which I can read to catch up?

Now, here is something for real Apple2 experts  :-)Apple Disk II - the diskette spin motor won't start, all other functions seem to be OK, but with floppy not spinning its hard to tell. The analog board looks OK, the "motor on" signal is generated, the motor itself spins when powered. I traced the problem to the speed control board (SCB), initially I suspected Q4 (the power transistor), but it looks OK, BUT ... Q3 is faulty!  There is no visible damage on the board, no signs of overheating, etc. It is rather rare that a low power transistor fails by itself...

I thought it was the power supply but it appears to be fine as all + 5 V +12V -5V and -12 V measures correct from plug and back of the motherboard. When switched on, speaker clicks but no beep, no power light or display. I can feel heat when I touch 6502 and the roms but ram chips all cold. I have also reseated all the chips. I am now stuck at what to try next. Any pointers would be much appreciated.

Got my first Rev 0!  It's in really nice shape.

When I first powered up, I was getting a solid white screen.  If I powered down and back up again, it would sometimes display a screen full of Gs.
