#184711 - It's a long, circuitous path ...
Responding to: ???'s previous message
You can do whatever you want ... but there is always a price to pay.

For about $2, you can buy an up-to-date MCU that allows you to program it serially. That's true of 805x's and it's true of others, e.g. ARM, PIC, etc. However, it's a LONG reach from starting to program a microcontroller to getting anything useful done in a robotic context.

There are IBM-PC-compatibles that fit on very small boards and are routinely used to operate robotic systems. They don't just cost a few bucks, but perhaps that's what you really want to consider.

I'd recommend that you find the original datasheet for the part you've mentioned and find out what it really is. Then, I'd recommend you look at the datasheets for the more modern versions. Most of them will do EXACTLY what the old, no-longer-manufactured version you've mentioned will do, and, in many cases, much more.

Yes, we built robotic systems at one time with those old parts, but there's a reason we don't do it any longer. It can be done, of course, just as the old payroll software on an old Apple-][ will still do what it always did. You might find it a bit easier to do something else, though.

How to write programs to internal memory with RS232???      Jacob Drake      11/11/11 00:56      
   What processor      Per Westermark      11/11/11 01:05      
      And the winner is...      Jacob Drake      11/11/11 11:13      
         fuggetabutit        Erik Malund      11/11/11 11:42      
            Hmmmmmm      Jacob Drake      11/11/11 11:53      
               sure there is      Erik Malund      11/11/11 12:15      
               Costly failure      Per Westermark      11/11/11 12:20      
                  Well, the UV thing confuses me...      Jacob Drake      11/11/11 12:26      
                     well, then ....      Erik Malund      11/11/11 12:56      
                     OTP or mask-programmed      Per Westermark      11/11/11 13:00      
                     Isn't that a clue?      Richard Erlacher      11/11/11 14:09      
                  Wrong! It won't work with THIS part!      Richard Erlacher      11/11/11 14:08      
                     8032      Per Westermark      11/11/11 14:39      
                        Actually ...      Richard Erlacher      11/11/11 23:50      
                           What situation would that be?        Per Westermark      11/12/11 05:25      
                              I think you're confusing two different parts.      Richard Erlacher      11/13/11 01:09      
                           There's the thing!      Andy Neil      11/12/11 05:37      
                              It all depends on what you mean by experienced.      Jacob Drake      11/12/11 12:54      
                                 RE: It all depends on what you mean by, "experienced"      Andy Neil      11/12/11 13:03      
                                    "Level" is such a relative term      Jacob Drake      11/12/11 17:35      
                              That's the reason      Richard Erlacher      11/13/11 01:15      
                        8032?      Jacob Drake      11/12/11 00:47      
                           Yes - but is it worth it?      Andy Neil      11/12/11 04:30      
                           It's a long, circuitous path ...      Richard Erlacher      11/13/11 01:24      
                     I have an external UV EPROM      Jacob Drake      11/12/11 00:38      
                        If you don't know that, ...      Andy Neil      11/12/11 04:35      
         Unless you have specific interest in vintage electronics ...      Andy Neil      11/11/11 13:13      
            So...I've made a decision..sorta      Jacob Drake      11/12/11 23:51      
               One step at a time      Andy Neil      11/13/11 00:21      
                  Any specific one though?      Jacob Drake      11/13/11 00:28      
                     This one?      Andy Neil      11/13/11 01:04      
         Not this one!        Richard Erlacher      11/11/11 13:55      
            Hmmm, a goal?      Jacob Drake      11/12/11 00:44      
               Wrong road!      Andy Neil      11/12/11 05:07      
                  Regarding knowledge of electronics.      Jacob Drake      11/12/11 12:57

                     out of sheer nostalgia      Erik Malund      11/12/11 16:44      
                     It might, in fact, be a good thing to go back farther      Richard Erlacher      11/13/11 01:37      
                        Interesting      Jacob Drake      11/14/11 00:15      
                           You need to know much more about two things ...      Richard Erlacher      11/14/11 12:51
