Hello, I need your help. I have a juke-box Rock-ola model Nostalgia 1000, with computer-board signed SYSTEM 2 54910-A. On this board there are two eprom label signed 544790-32 and 544780-32, and the third eprom is absent. Of this eprom I know only the symbol appearing on the printed circuit board, PROM 2758. Let me know if you know how to find this eprom . Thank-you.
