Thanks for the files.
The easiest way to make a ROM image is to use the ROMCOPY LEX; for true ROM image collectors the best way is to make a dump using PEEK statements (examples at various places) because it preserves everything.

Anyway, the individual files are good enough to have an idea of the content.
The LEX files are always interesting to explore:

Code:

LEX2, LEX4 and LEX5 are known LEX files with common keywords.
LEX1 implements a SDCCHR2 keyword, that is used once in the SDC program.
LEX3 seems to implement commands for a serial communication, but the keywords are not used in the programs. Hard to figure out the usage without any example.

[edit:]
The ROM was likely to be used with another ROM, because there are statements such as
CALL CIO(E) IN FFF
in the programs, referring to a FFF file that is not within this ROM.
FFF likely stands for "Flex. File Frmt.", the name of another Abacus ROM. One can currently be seen on eBay.
