Can't you order the parts by mail?

By the way, don't use this circuit

It's trash! You can see it from the fact, that any series termination resistors are omitted, proving that the "designer" has no glue at all how to handle transmision lines!!!

   the 'weekly' question get the weekly answer            01/01/70 00:00      
   Add some pull up resistors (4.7K\'s) on LS device.            01/01/70 00:00      
      risque business            01/01/70 00:00      
   Home made JTAG            01/01/70 00:00      
      It is so refreshing to see thing like this instead            01/01/70 00:00      
         Tested!            01/01/70 00:00      
            have you 'tested' that the flash caps are fully            01/01/70 00:00      
               Atmel does that            01/01/70 00:00      
                  I think you are wrong            01/01/70 00:00      
                     I don't think so            01/01/70 00:00      
                        yes, and no            01/01/70 00:00      
                           Bah, shoot that designer :-)            01/01/70 00:00      
                              not the chip designer            01/01/70 00:00      
                                 JTAG x Flash Data Retention            01/01/70 00:00      
                                    nope            01/01/70 00:00      
   Tnx for answers...!            01/01/70 00:00

      Only LS chips            01/01/70 00:00      
         there is the mail            01/01/70 00:00      
            here is world´s end            01/01/70 00:00

            What more fast than 9 ns?!            01/01/70 00:00      
               I do not understand. What I said is not to find s            01/01/70 00:00      
         Then stop doing in electronics!            01/01/70 00:00      
   re: AT89S52 error            01/01/70 00:00      
   Somebody test buffer CD4010?            01/01/70 00:00      
      the CD40 is sloooooooow compared to HC            01/01/70 00:00      
         What more fast than 9 ns?!            01/01/70 00:00      
            Not the speed is reason only            01/01/70 00:00      
   But and the pull ups in buffer´s out?            01/01/70 00:00      
      Does that suggest anything to you?            01/01/70 00:00      
      Type "74VHC244" into the search window            01/01/70 00:00      
         show the calculations            01/01/70 00:00      
      Schematic of programmer using 74LS244            01/01/70 00:00      
         Circuit that i am using            01/01/70 00:00      
            the very reason            01/01/70 00:00      
               Right...!            01/01/70 00:00
