The principle is similar to the selection of NVRAM on Hitachi

I have tried several ROM's and LDR's but no luck. No access to SA to determine the correct version of original ROM.
A friend of mine (member in this forum) confirmed that the ROM version of my defective drive is 00030078.

This is interesting. Or there is something wrong...
