Hi All,

Confused I am.

I am the original owner of a 24 year old Omni V.9 from 1991, a last production run unit. It still runs beautifully.

On my logic board in the Omni V.9 the NVRAM chip is identified as U8 and id'ed as a X2404P on both the schematic and on the top of the chip itself. No manufacturer is named on it.

It is only an 8 pin chip and does not physically resemble the chip shown on several of the links in this thread in the past few days.

It is a thin chip as with others on that board and with no apparent "battery bulge" on its top surface. On the schematic, pin 8 of the chip is Vcc taking +5V from the radio off of the logic board.

Am I missing something here? Could TT have changed this chip in a later production run of the logic board? Why has it not failed after 24 years if it's life expectancy is +/- 10 years?

Info and any speculation appreciated.

BTW as asked earlier, what functionality is lost if there is a battery in it and it fails.

Thanks,

73 de N1LQ-Dave
