(ET) Walking down memory lane on old stuff

[Neil Dennis <wombatt gmail com>]

Total "off the wall"

I picked up a digital training system unit somewhere, lent it to the 
school tech class, guess they just stashed it.  Has a whole batch of 
stuff like J-K flip-flops, and and nand gates, even a seven segment 
display and a batch of LED's. So got it back and after playing a bit and 
straining the memory got it running as a hexidecimal counter, lighting 
the 4 leds in sequence and an "F" at the right time.  Gotta think a bit 
and see if I can do the whole sequence of letters and numbers but don't 
think there are enough gates.

So, put it away, take it to school next fall and do a show and tell.

Good to get the brain in gear, wombat
