Ah well: thats 6502 postfix assembler. IO ( to FORTH ) is via a 16 bit
stack simulated by the X-register.
I don´t have the 6502-manual online, but the 68HC08 is similar
( but bigendian ):

Cleaned up original layout may be easier to read:

Obviously I'm not used to "postfix assembler" - for me, this one appears
as broken as the other... :-)
