#131276 - BUS
My basic design for my 8051 programmer/system combo is setup.
However, what I want to do is make a bus connection point. Initially, I thought of using a jumper block (about the size and style of an onboard floppy drive connector), but the only problem I see is that I cannot connect the wires through it. In other words, I want wires to come out of both ends.

I am working on a single sided PCB and would like to use the least amount of wires to jump traces.

Here is an image:



What it is showing is that I'm trying to figure out how to include a connector which connects the pins to all of the address and data lines, without disrupting the other connections.

I have a problem with using standard jumper blocks (like the floppy jumper block found on pentiums), because the spacing is so small, I'm afraid that when I drill, I'll drill directly through the track.

I have a problem using a parallel port plug and a serial port plug as a connector for the same reason.

Also, I like to make my tracks thick enough so that when I solder, the track won't lift so easily off of the board.

I usually keep my track lengths to a minimum of 0.38 mm.

I shop at Sayal Electronics (website is sayal.com). I was wondering if anyone can suggest a better connector, that Sayal offers.

I need both the male and female version, of the connector, because I will make add-on components.

   does not make sense, pls explain            01/01/70 00:00      
      100 mils width is too small            01/01/70 00:00      
         Use 8052.com            01/01/70 00:00      
         in one direction, in the other it is .100            01/01/70 00:00      
         Drilling holes with 100 mil pitch should not be...            01/01/70 00:00      
            None at all!            01/01/70 00:00      
            The largest drill diameter is 0.050"            01/01/70 00:00      
               It's all coming back...            01/01/70 00:00      
                  What do you mean "coming back?" It's still here!            01/01/70 00:00      
                     the rest of us regard this a trip down memory lane            01/01/70 00:00      
                        Yes, paper clips, zippers ... they're still around            01/01/70 00:00      
                           yup, slow things down            01/01/70 00:00      
               It is 0.80mm NOT 0.080"            01/01/70 00:00      
                  One's too small, the other's too large            01/01/70 00:00      
         It\'s really not too small ...            01/01/70 00:00      
         Terms; Width v Pitch            01/01/70 00:00      
   if it is all or none            01/01/70 00:00      
      I'm using a Single Sided board...            01/01/70 00:00      
         I don't understand...            01/01/70 00:00      
            yes            01/01/70 00:00      
               If you mean what I think you mean.            01/01/70 00:00      
               use an IC socket then...            01/01/70 00:00      
                  a good ides does not suffer from being repeated            01/01/70 00:00      
                     I missed that, sorry...            01/01/70 00:00      
                        what is a "component platform"?            01/01/70 00:00      
                           thanks            01/01/70 00:00      
                              here we go            01/01/70 00:00      
                                 oh now I remeber            01/01/70 00:00      
                                    they are available in 0.3" as well            01/01/70 00:00

                        So is the 89C51ED2            01/01/70 00:00      
                           there are PLCC sockets that spread the pins to 0.1            01/01/70 00:00      
                              Yep.            01/01/70 00:00      
                                 ok            01/01/70 00:00      
                                 you don't have a proper devboard            01/01/70 00:00
