The numbers below are from a2 8-pin EPROM. Does anyone know how to identify this chip? It is from a Fuji Micrex PLC, and I edited the program in the PLC's ram with a Fuji D25 Loader. Now, I need to re-program the chip to install it back into the PLC for permanent memory.

I need information on the chip, a chip supplier, and an EPROM reader/writer for the 28-pin configuration.

Thanks for any help.

new micrex-f plc no need that chip,usualy 89c125

Thank you for the new chip ID. I complicated my own problem by mis-counting the pins on the chip. The Micrex F model today uses the 32-pin chip.

I purchased a chip reader, which has been able to read the new chip. Unfortunately, the program is in hexadecimal code. So I need to be able to interpret it into a usable ladder logic model before I can edit my machine programs and then write to a new chip.

Maybe some help can still come my way with my Fuji projects.

Thank you again.
