That's good news.

Indeed it is.

I was a little worried about U36, as I pulled a couple of traces when desoldering it. Not sure how but they seemed particularly fragile, almost as though they were already damaged. I probably could have used my hot air to ease it out after the desoldering gun, but I am always worried about popcorning with these boards, and since I have a new hot air gun I'm still getting used to so I wanted to be careful.

They were pins 46 and 47 on Gary to pins 2 and 5 on U36, so actually pretty easy to repair and only one of them is relevant for the internal FDD, the other being for the external FDD.

The weird stuff that is going on does seem to point at Gary going off the rails, but we'll hopefully find out tomorrow.

I'm guessing that it's the sockets. With the number of videos I've seen of A500s playing up and Gary being suspect it's always been the socket.

Good job I have new sockets on order too then. I guess new sockets is probably a mandatory fix for A500s.

They are double wipe, but something looks a bit odd about the metal, kind of grey and dull. At least the Fat Agnus socket is already done.

Hmm, interesting.

I decided another thing I could do while I waiting was to run an audio test to see how Paula was doing.

The test crashes every time.

The address decoding is probably right up the creek.

Very possibly, it starts and then crashes badly.

Not sure if I said, but I also swapped out the CPU and that made no difference.

More likely a poor connection on Gary on one of the address lines so Gary isn't seeing the correct address and hence not decoding addresses correctly.

Very likely.

I'm sitting eagerly awaiting my sockets and other spares!
