Mice not recognized

[garyg]

I brought my Quikpak A4000/060 back to the engineer who gave it to me to discover why it wouldn't boot anymore (it turned out that the '060 card had shaken loose).

Now that I have it back when it boots the cursor won't move, even though i've tried two different mice (one that works with another Amiga).

Does anyone have any idea what could be the cause (I don't want to bother my engineer friend because he's very busy and lives 100 miles away anyway)? Hopefully the mouse port didn't get damaged or anything.

Hopefully one of the CIAs didn't get damaged... that will be a very frustrating repair.

There's a chance it could just be the keylock. Did it accidentally get set to the locked position? Or maybe the connector is plugged into the motherboard backwards? Check some photos online to see what is correct.

The Quikpaks were 4000Ts, weren't they? In that case maybe the cables to the ports module are not installed correctly?

I hope some of this helps and you're able to solve the problem!

OK, will do.

Yes, they were A4000Ts, alright, but inasmuch as it booted OK previously the cables should be OK, and I can't think of any way he would have changed them.

Well, for a minute I thought you two must be right: the arrow on the lock was pointing to the right on the computer and points to the left on my A4000 desktop.

Not having seen the key for about 20 years I took a flat-blade screwdriver and managed to rotate the lock on the A4000T/060, then booted it, but the mouse still doesn't move :-(

I didn't see this post before unplugging the connector that controls the lock. I did so this afternoon but the cursor still doesn't  respond to a mouse click. I'll re-read the posts before resigning myself to assuming it's a bad CIA chip.

When it boots the cursor doesn't respond to any mouse clicks.
I have no capacity to measure voltage levels or solder things
