That, OTOH, would indicate that at least *SOME* of the logic board is still working, and that the processor seems to be doing *something* - that beep is actively generated, IIRC. > After this i've tried to remove the three eprom to have it cleaned ... but > after this nothing.

I know that the PETs without the 80-column CRTC (like the 2000, 3000 and "slim" 4000 series) can show weird results if one of the 2 5V-regulators is busted. Another possible explanation would be that (part of) your RAM is busted. That said, I have no clue, never ever having laid my hands on a 8032.

They contain the operating system of the computer - including but not limited to the BASIC - it also contains the kernal, which is responsible for low-level things like reading the keyboard, operating the IEE488 bus, etc. etc. > Can the per work without those eprom?
