Little odd this one.
An Amiga 2000 that someone has already had a go at. Its a nice machine, has a 68020 coprocessor card and two hard drives but the battery has leaked.
With the CPU removed, one pin of the socket is completely missing ! So new socket fitted. The Paula socket is looking a bit tarnished, so had to buy a PLCC removal tool to clean up all the contacts.
Now boots, but the hard drive seems to need a kick, suspect the heads are sticking.
Whats odd is the mouse port wont work. In place of F1, there is a heat damaged 1K ohm resistor which when a mouse is plugged in, is dropping the voltage at the mouse to 2V which isnt enought to run it and a lot of the tracks and vias are seriously mechanically damaged. Got a new pico fuse on order but for now a 40 ohm resistor is fitted as a very temp measure and the mouse has all but leapt into life except the right mouse button.
Suspect that one of the T EMI filters has failed so now on order too.
Think I will need to fit a new SCSI drive though.
