These ROM images in Intel binary format are from an early 7081 (Serial Number 180) with 2564 ROMS that had been updated during the instrument's life.

I received an email in December 2011 from an engineer at Ametek (formerly Solartron), telling me that this ROM set is revision code DD which is the final firmware release issued for the 7071 and 7081 meters.

I am told they will work equally well to re-program meters equipped with 2764 ROMs. 

The CRC16 checksums are:
 
 IC430	3238
 IC415	C5C0
 IC414	1260 
 IC413	B958
 IC412	ED50

The ROM on my floating logic board is also a 2564 and has also been updated.

The CRC16 checksum is:

 IC803	8900
