Does the caps-lock key flash or does it never light at all? Those keyboards go bad pretty often- they have their own CPU that dies.

the caps-lock key never light at all, but the other lights (floppy and power) work

You could swap the CIA chips to be sure (carefully) but the keyboard is probably just dead. I don't know that they can be fixed, so you'll just need another. You should be able to get another A500 for parts cheaply that has a different problem and swap them.

Somebody on here had this the other week with a 1200 and it finished up being the green strip connecter from the keyboard to the motherboard.

Have you checked that this is inserted correctly

I had something like that back in 1991. It turned out that after all the typing on the keyboard (SAS-C

), that the keyboard had bowed in the middle... I scrunched up some newspaper and put it under the keyboard, then bent the keyboard back to straight. I've noticed this happen to a few other A500s too.

Probably not the reason that yours isn't working, but I thought I'd just tell you in case.

I don't think the 500 connects with that same type of delicate strip. I think it uses a small DIN header, but I could be misremembering.

You could be right - I was answering the question from work and trying to remember what the insides of my 500 where like

I've just looked in a 500+ and it's a small header plug - so I'd guess the 500 would be the same.

Could be worthwhile still checking and making sure it's fully home though

The A500 keyboard has a pin header in the mobo, oriented!

If the LED works OK, the keyboard CPU is plain dead. 2 of the 3 rightmost wires are for the power and floppy LED. No way to turn it around to make it work.

Worse: it will kill kill the motherboard! At least I warned you!

Buy another working keyboard or a broken down (but the keyboard, of course) A500/+ for parts.
