#CIA 8520 chips help me
I have been having problems with my Amax II+ and using my floppy drives.
So I bought two CIA 8520 chips at my local dealer.
I took the old ones out and put in the two new ones. Then my computer
only showed a grey screen upon powering up. So I put the old chips back
in and my Amiga 3000 booted up just fine.
What do you think is up?
I noticed the original CIA 8520 chips in my Amiga had different numbers on
them. The two new ones I got have different numbers on them too. They
say
CSG
318029-
8520PD
4691 24 The other one says here: 4491 24
Do they go in a certain order? Why different numbers?
