Apple II

I have a II+ with paint in several that looks like it's about to chip away. There are also some other areas where the previous owner drilled holes into it and it's generally in a sorry state.

So I'm thinking of stripping, filling the holes and repainting it.

Would that require any type of special paint to keep the textured surface, or is that how the plastic is already moulded underneath?

Also, what's the best way to remove the existing paint?

I was wrong when I connected my disk II to the controller board

row 2-4-6...20 was connected on row 1-3-5...19

any idea of way may have burn ?

the 74LS125 is dead, exploded, I changed it

then engine is turning, and I hear a bump, so I guess the stepper is working

connection realized with my error
gnd 1 2 stepper 0 ok
gnd 3 4 stepper 1 ok
gnd 5 6 stepper 2 ok
gnd 7 8 stepper 3 ok

+12 15 16 rddata burnt ?
+12 17 18 wrdata burnt ?
+12 19 20 wrprot burnt ?

any idea of the conponent that burnt in this case ?

thanks

So I got that Rev 7 board with all the missing sockets and am about to attempt to restore it. I am wondering if anyone knows of a source for correct sockets.. or if I should just make do with the generic new ic sockets I have kicking around?

I have a Disk II, after a lot of cleaning, I have a disk II reading/writing the floppy disk

but I have some read error on track 34, it's not a bad floppy disk (the problem occurs on almost
all my disks)

I've adjusted the speed, it was a bit slow

but know I have no idea,
occasionally it works and read the entire disk...

but most often it fails on the last track

any idea of what I should to to solve this problem ?

thanks
