Yeah, I'm skeptical about that myself.

Nope, sorry, don't have a dumper for that.

They are socketed though, so I could just mail them off to someone.

Or is there an easy way to dump them? Like, "apply an x-bit string on pins y..z and read the q-bit value from pins r..s as result"? If so, then I could pull it off smile

You could build this I suppose: http://cgfm2.emuviews.com/elec/pal.php laugh

Anyway it's not really that important. Just something nice to have.

Umm... okay, this looks like an awful amount of work. In that case I'd probably prefer mailing them somewhere, should they turn out to be helpful at some point.

It should be possible to design some smart(er) software that does all the analysis, so that you'd just have to hook up the PAL to a microcontroller and the software does all the heavy lifting... But I'm not really sure if that would be worth the trouble

Gah, the epoxy blob with all the lines to it is staring me in the face.

Okay, right, CPU is under that epoxy blob and we've no idea what it is, forget I said anything.

At least we know the supporting chipset smile

I'm pretty sure they want dumps not hacks.

actually, those are dumps from carts sold in Russia. as such they are eligible for inclusion, as most bootlegs in MAME...
