 		 #167179 - 8048 -> 8051
Responding to: ???'s previous message
"I use a 8048 in a self-bild software development kit for direct code data-entry and running and debugging code. (hex-keyboard and 8 x L1416 displays).

"I like to use 8031 instead of 8048 ..."

You will probably be better off looking for an 8051 development kit. There's one here, at http://www.8052.com/sbc/ and there are a number of them on the internet.

      This might be a bit trickier than you think ...            01/01/70 00:00

   Maybe you should reconsider the system configuration            01/01/70 00:00      
   8048 -> 8051            01/01/70 00:00      
      if you buy a SILabs kit ...            01/01/70 00:00      
         Beware of 'C'-only systems ...            01/01/70 00:00      
            Pardon??!            01/01/70 00:00      
               I have to believe their tech support guys ...            01/01/70 00:00      
                  The SILabs 'tools' are KEIL            01/01/70 00:00      
                     My point, exactly!            01/01/70 00:00      
                        WHO states that he has to use Keil            01/01/70 00:00      
                           There's probably good reason for that!            01/01/70 00:00      
                              the KEY word            01/01/70 00:00      
                                 You can't evaluate with something that's not complete            01/01/70 00:00      
                                    But they obviously can't give away the complete product            01/01/70 00:00

                                          what specifically does not work?            01/01/70 00:00      
                                       Of course not!            01/01/70 00:00      
                                          Agree with you there!            01/01/70 00:00

                  the old familar tune and singing it off key            01/01/70 00:00      
                     Lots of C code to fill 2kB or 4kB            01/01/70 00:00      
                        and how will that help the O/P?            01/01/70 00:00      
                        maybe if the lines are....            01/01/70 00:00      
                           Don't you worry            01/01/70 00:00      
                              It was a kind of joke.            01/01/70 00:00      
                        Illustrated here            01/01/70 00:00      
                  2K of binaries for just a few dozen lines of 'C'            01/01/70 00:00      
                     perhaps, but the O/P didn't say he wants to use 'C'            01/01/70 00:00      
                        You were the one who raised it!            01/01/70 00:00      
                           True enough, but ...            01/01/70 00:00      
                              read the Keil manual            01/01/70 00:00      
                           I don't believe that's the case            01/01/70 00:00      
                              Yes, it was definitely you.            01/01/70 00:00      
                                 Emulation possible            01/01/70 00:00      
                                    why not emulate 8048 in 8051            01/01/70 00:00      
                                       Interesting idea, but ...            01/01/70 00:00      
                                          how to 8243            01/01/70 00:00      
                                             It could be quite straightforward            01/01/70 00:00      
                                                it could be....            01/01/70 00:00      
                                             how to 8243            01/01/70 00:00      
                                                You really should open a museum!            01/01/70 00:00

                                 Yep ... you're right ...            01/01/70 00:00      
                                    SiLabs parts            01/01/70 00:00      
                                       It's not at all clear what the problem is            01/01/70 00:00      
                                    I know that you live in the past            01/01/70 00:00      
                                       it's all about the timing ... and the support            01/01/70 00:00      
                                          If it matters, then you shouldn't be asking            01/01/70 00:00      
                                          living in the past, you would not know of ...            01/01/70 00:00

                              "Most coders"            01/01/70 00:00      
                                 do you really have any evidence            01/01/70 00:00      
                                    You clearly haven't though about it!            01/01/70 00:00      
                                       which is the correct procedure            01/01/70 00:00      
                                          Not so ridiculous ...            01/01/70 00:00

                     It's not pointless, Andy            01/01/70 00:00      
                        2kB of code space is quite a lot for evaluation            01/01/70 00:00      
                           One could answer this in a number of ways ...            01/01/70 00:00      
                              I think I know why Richard keeps arguing against C ...            01/01/70 00:00      
                                 In that case, where's the benefit?            01/01/70 00:00
