Would you put plastic handles on a piecc of antique furniture? Would you make the seatboard for an antique longcase clock from MDF? Both are easily reversable, BTW. > If you have the ttl logic bits lying around and know how to use them, fine. > Still would probably need debugging. FWIW I have made programmable dividers on a couple of occasions recently (one was a 100/120 flash-per-second stroboscope, the other was the transmitter half of a modem to talk to TDDs). Both of them worked first time. I guess it's just what I am used to. -tony
