There have been many many things in my life that I had to wonder - why? But one that keeps coming back is no matter how big the device is, it is still 1 or 2 pins short? Why? Currently I am using the biggest device I can find in the 8 bit world 100 pins. I don't want the latency of port expanders so I am using some buffers to double up on some inputs. Yet still I found myself looking for a way to simply add an led.

I resolved the lack of I/O, but just have to wonder -WHY?
