Heres a blast from the past - the 68HC805K3
Does anyone have access to the programming instructions for directly programming the above, ie pins, signals, voltages, commands etc.  The original Rev 1 datasheet did not include this information.  As a "Plan Z" I need to investigate making up a programmer to get a client out of a bind. 
In case you're wondering why we need to do this - Our client has a current mask part (68HC05K3) and they need to trial new peeprom settings.  The mask part has the peeprom pre-programmed and secured at Freescale so we cant demo the peeprom changes with the mask parts.  The 805K3 is no longer manufactured but we have access to a small stock into which we need to program code/peeprom .
