2006-09-02 - vspsim/ISM/opcode_map.html : hit the "reload" button to force highlighting a new item. Just changing the instruction (after the '#') in the address bar then hitting Enter does not force the page to be re-evaluated and the highlight does not change. The page however scrolls to the appropriate instruction, so it's not a major issue. 2006-09-06 - the load/save functions are ... beyond ugliness - the DB and DH pseudo-instructions don't accept more than 1 operand ==> 2007-04-04 : fixed. 2007-03-28 - SUBB and SUBB1 : the result is still unspecified. Is it better to have O/-1 or 0/1 ? And is it easier to compute/wire ? 2007-04-01 - the order of the register fields for the GET & PUT instruction is not definitive.
