I finally had time to mess with my programmer and decited to try and erase the tms 2532jl chips that came on my pacman plus to make it a regular pacman. But i havent even been able to erase them. I have one of those cheap erasers from ebay and have left them in there as much as 40 minutes and nothing. All but 1 chip i can still read it and verify it with a good bin file and all info is still there.1 chip wont verify but it did not erase either. From what ive read these chips suck so i guess i need to order some eproms. My question is what options of chips do i have that will work in my board. Thanks
 
Options?

TI, Motorola, and Hitachi all made the 2532. Not sure how many others did.

You should check for yellow or red film over the erase window and clean off all gunk from it before you pronounce them dead. Also, make sure they are under the bulb in the eraser as they need strong, direct light for erasure.
 
That was the problem. I cleaned them good and i was able to erase and program them all. Thanks for your help.
