The SBC is OK as it is - except for the LCD pinout, of course... :-) You are presenting mostly the "biblical" '51 in the Book, don't you. The derivatives available in DIL - RD2s, DS89C4x0 - provide ample opportunity to demonstrate most of the "advanced" stuff.

I could imagine quite a couple of improvements, but only as a facelift of the existing design, or addition/modification of certain peripherals.

For those interested in all the modern stuff - Silabs, uPSD3xxx, LPC9xx, Ramtron Versa, Infineon XC8xx, etc. - it is easy and relatively cheap to acquire their respective baseline devkits.

   What about PLCC?            01/01/70 00:00      
      interesting, but ...            01/01/70 00:00      
         A PLCC Socket is solderable            01/01/70 00:00      
         OOPS            01/01/70 00:00      
            I was wondering...            01/01/70 00:00      
               PLC, not PLCC            01/01/70 00:00      
      better if socketed            01/01/70 00:00      
         Socketed - Yes            01/01/70 00:00      
            perhaps you have missed the point            01/01/70 00:00      
   multi-option implementation            01/01/70 00:00      
      Not much            01/01/70 00:00      
   It depends on the board quality ...            01/01/70 00:00

   Supply PCB with only the smd micro placed            01/01/70 00:00      
   leave it            01/01/70 00:00      
      that makes sense to me ...            01/01/70 00:00      
   simple is still good....            01/01/70 00:00      
      why bother            01/01/70 00:00      
         last time I bought 32KB SRAM I paid $0.48US            01/01/70 00:00      
         use part of a bigger one            01/01/70 00:00      
            that's not really a problem...            01/01/70 00:00      
               it is a problem if you rely on DIL packaging            01/01/70 00:00      
                  what is your definition of "obsoleted"?            01/01/70 00:00      
                     Problem            01/01/70 00:00      
                        Have you seen this?            01/01/70 00:00      
                     Over the last year ...            01/01/70 00:00      
      Gee ... that thing really costs a lot ...            01/01/70 00:00      
         no, it does not            01/01/70 00:00      
            $50            01/01/70 00:00      
            I meant this one            01/01/70 00:00      
   Thanks for comments, keep them coming            01/01/70 00:00      
      nothing comes free...            01/01/70 00:00      
         or            01/01/70 00:00      
         No problem with other design            01/01/70 00:00      
      How about a mezzanine board ... and some tools?            01/01/70 00:00      
         with some really slick code ...            01/01/70 00:00
