So the plague could not be as widespread as we may have though in the first place.
So the plague could not be as widespread as we may have though in the first place.That would be good news, also if the rest of the hardware is the same (latching etc.) so we can substitute the Mostek with a normal 27C64.
I think all_repair has solved it for you all. a search on the number he provided as a part number 03468-65501 throws this up
ROM program HP3468A-ROM
I have attached The rom from that site to this.
...
I have done a short comparison to Sailors binary, unfortunately his binary data is in some sort of s19 format and can't be directly compared to the rom you posted, however on first sight there are a lot of similarities and also a lot of differences.

I have attached The rom from that site to this.That would be great, I have done a short comparison to Sailors binary, unfortunately his binary data is in some sort of s19 format and can't be directly compared to the rom you posted, however on first sight there are a lot of similarities and also a lot of differences. The differences are mainly bits that went from 0 to 1, this is just a very short first glance and comparison of a few strings in the first 4k. Perhaps Sailor can provide a comparable binary formatted file so we can do a 1 on 1 comparison.
It looks promising

I have both bin and intel hex format of my rom in my attachment. You may see if it has the same format aa sailor. I can't verify the chinese site rom and my captured bin now. Anyone can verify?
I am going to give it a try, don't know if I have enough time to get so far but will try a building a small converter pcb and a 27C64 in the actual device.
Now the question is does it matter if I connect the original /CE of the MK36000 to the 27C64 /CE or /OE they both have the same function as far as I can tell in a short glance on the datasheet?
