The 8/A was compatible with the earlier machines so software should work
unless they were requiring an option which isn't on the 8/A.  OS/8
is your best bet.  TSS/8 won't work with an RL drive.  

For multi user operating systems the only one that will run on your
hardware is Multos-8.  The version that has been recovered doesn't seem
to operate well though.
