Thanks to a very kind gentleman, I received in the post today an Itron FG209C2 VFD and an ER-3400 NVM for my ailing 7081.
Naturally, it is still unwell even with these parts fitted, and getting it working will clearly be a labour of love.
I issued a calibrate,zener,103 and received in return a "Cal incomplete" message. Power off followed by initialise also gets me a "Cal incomplete" message to it looks like the new NVM is OK - yippee!
When I then try
I get a "Zero too large" error message so there's clearly still a fault on the floating boards. Mrs. Murphy said (*) that it would still have problems even after replacing the display and NVM, and boy was she right! Clearly it will be a labour of love to get this working again!
If anyone has any suggestions as to what is likely to be causing the "Zero too large" error, I'm all ears!
(*) Mrs Murphy's law: Murphy is an optimist.
