EIP 545A option 08 Eprom

[pieroandreini]

I recently bought an EIP 545A frequency meter with option 02 (power meter).
I also wanted to have option 08 (GPIB) therefore having the diagram available I redesigned the PCB and as soon as it arrives I will start assembling ii but I also need the file to burn the Eprom U16 on CPU card.

In another post where another person wanted to add option 02, someone wrote that the Eproms must necessarily all have the same firmware version, can anyone tell me if it's true even for option 08?

The following EPROMs are currently present on the CPU card:
U13 6500002-01H
U17 6500002-02H
U15 6500002-03H

The only eproms I managed to find are the ones I found here: https://www.qsl.net/n9zia/vision/ but U16 seems not to be present unless it's the file U-- 6400002-03F W29 TMS2516JL -45in folder 545A CCN 2204 with Options\A105

Can anyone help me?
