Ok thanks Mike

It means that my 8085 disassembler is... humm... (it reports this sequence as unknown instruction... like most of the RST vectors entries). I did not check in the datasheet to be honnest, just trusted the software

I will try another disassembler then (for those being interested : the problem I saw comes from DASMx. It worked perfectly to disassemble the 6303 code from my DSS1... but clearly not the case for the 8085)

Is there a 8085 disassembler you would recommend Mike ?

Benoit
