That's a bit of a tricky one, is it definitely the PAL that's dead?

Death by blowing its top. It's the pal that maps the joysticks movement's. So it's hand to have

I've had a hunt, but I'm coming up empty sadly. Probably of an age where it may be easier to find a working card and copy it. I found the card easy enough, but nothing from a JED point of view.

Yes cards are rare now and many of them people part them out for every dollar. Vcf Midwest computer show is coming up i have the word out there to collectors to check and see if they have the pal on them maybe try a read of the part

I had to recap the motherboard a ibm 5170 the tantalum caps went low resistance
