Its been years since Ive had to use my PB10 programmer, but after brushing up on the system a bit it all came back to me 
I fixed a few Tron roms and now I want to fix the 136031.102 on my ESB board that is throwing an error so I pulled the rom, erased it, and I have tried to program it 5 times (erasing between each time). It seems to program the first bit then it errors.
Could my issue be that I need a new 27128a chip? Im using the Mame romset for the bin, but I dont think thats the issue?
Any help would be appreciated
Thanks!
