Hello

I'm new here .

I need to flash rom for my Centaur II and I cannot find datasheet for this rom.
Can someone tell me how to set programming voltages for this memory chip.

Thank you for great answer.. I will use this eprom
utsource.net/ic-datasheet/TMS2532A-25JL-1392323.html
becouse my programmer TL866CS Pro cant deliver 25v for programming 2532 and 2532A can be programmed with 21v.

Mpu board was missing in my machine so I bought AS-2518-35 with jumpering made for 2532 like here
ebay.com/itm/Bally-Centaur-Pinball-mpu-35-chip-set-/220779506923?pt=LH_DefaultDomain_2&hash=item33677beceb

and now i plan flash two 2532A roms.

My plan is ok ?
(Had to cut links becouse new users cannot paste links)

I found 2532A from trusted seller and I will try flash'em because I dont have to resolder jumpers with these EPROMS
Thanks for helping me guys.
