They are a bipolar PROM 74s573 is a sub among others , they are not an Eprom.
If you have a good bin file for it then i could program you one no worries...$10.50 posted
...depends where you got the file from because i'm finding the sound prom files for the System 1 and early system 80 that are floating around on the net are corrupt and no good.
..at least ways i know the files for Hulk ,Torch , Spiderman , and James bond are bad because i've verified them against known good originals that i have and they don't verify , the check sums are different...even burnt one to be sure and it sounded terrible.
If you have a good file , or could borrow a chip from someone that i could copy , then i could do it no worries if no one else can do it for you.
...Otherwise your other option is to buy one from the Pinball Resource.
