What, "similar assembler syntax"?

Just some examples:

RORA
ASRA
TAB
TPA
TSX
STAB <8bit adr>
INS
ASLA
RTI
BLE

Let's see if you know what they do :-p

BTW: It could be that 'modern' assemblers use a different 'better' syntax.
I have seen i8080A/i8085A/Z80 assemblers where you could program with Z80
syntax for the older 'predecessors'. Since OP-codes of common instructions
are the same, it's just adding some check in the assembler if the
instruction you use is valid for the processor you assemble for.
