Hi One easy way to get the "eprom fail" message on the 53132 is to write settings to memory "a bit to often". I blew out a set of them in under a year back when they first came out...
They still worked fine, but they did come up with the error at boot. I suspect that they also did not quite save settings correctly anymore.

I wonder if it might be easier to run the OCXO from a new additional supply housed in the unit, there appears to be space for this (?) and feed the 10MHz into the external REF I/P?

Do you really need an > image of the eprom ? Regarding the eproms, your fault description matches what I've seen in 3 or 4 units, all at first glance functional. The worry is that the fault clearly was not there a few years ago and you have got to assume the worst, why should it stop degrading? The blank parts are Am29F010B flash and were cheap and available when I looked. Let me know if you want the image files I generated of good parts emailed, the set of images etc in various formats is about 1.7M (4 parts in 3 different file formats).
