Sorry to bump an old post. These chips are canceled at Motorola. Anyone know who is the manufacturer and their part number? I suspect it's Atmel but am shooting from the hip on that one.

From memory I believe it's a 27C256-20.
Re: Maxtrac 900 meg conventional firmware FVN4019A
It is a 27C256.
Since Mot doesn't sell them anymore, I make my own.
I have been finding them in old equipment like PC mother boards ( BIOS-ROMS ) and old modems, etc. Even old 800 mhz Maxtracs.
Blank with a UV eraser, copy with a generic EPROM "burner".

I have the burn once proms to make these. I have several ready to go. I also have the new conventional face plates to replace the trunking face plate.

I have the prom file for these and am slowly acquiring the 27C256 chips from various collections...and sometimes, if you open up a 900 trunking radio, I've found ONCE the old conventional prom taped to the inside of the case.
