#85202 - Or use a terminal program
Responding to: ???'s previous message
For serial programming, you need to power the device, connect a serial cable to UART0 (using a converter), run your favourite terminal program, apply RST = 1, EA = 0, and PSEN = 0 and follow the instructions given in the User Guide (don't be confused, it says DS89c420_user_guide.pdf but it is valid for 430-450,too) (press CR for autobaud etc.) Then you can "talk" to the micro, using the commands described there. When sending an intelhex file, make delays between each line sent - the datasheet says 40us programming time, so 10ms for a 16-byte line should be far enough.

By the way, as for the other part from your question, does 80Cxxx not mean it is a ROM-less part?

Need programmer for DS89C430 & DS80C310            01/01/70 00:00      
   The datasheet for 430 says:            01/01/70 00:00      
   Or use a terminal program            01/01/70 00:00      
   ... or do it the easiest way...            01/01/70 00:00      
      It works fine            01/01/70 00:00      
         Errata!            01/01/70 00:00      
   Does NOT work!!!Help!            01/01/70 00:00      
      Or can you tell me            01/01/70 00:00      
         DS89C420 ISP            01/01/70 00:00      
   Or maybe            01/01/70 00:00      
      I meant crystall at 4 Mh.            01/01/70 00:00      
      NOOOO            01/01/70 00:00      
         Did you look at PCB Layout?            01/01/70 00:00      
            No            01/01/70 00:00      
               I don't understant much            01/01/70 00:00      
   Heelpp!!            01/01/70 00:00      
      bad title, bad link            01/01/70 00:00      
         DS89C4x0 ISP            01/01/70 00:00      
         About the link            01/01/70 00:00      
            Link works here            01/01/70 00:00

   Back to the main issue...            01/01/70 00:00      
      No scope,            01/01/70 00:00      
         But this is the FULL circuit diagram            01/01/70 00:00      
            use something else            01/01/70 00:00      
            Oh no it isn't            01/01/70 00:00      
               Look at the bottom            01/01/70 00:00      
                  but..            01/01/70 00:00      
                     Cap on Pin 2 to connected Vcc            01/01/70 00:00      
                        which goes to show.....            01/01/70 00:00      
                           You 're right            01/01/70 00:00
