You people crack me up! Me being the computer "nurd" I am. I'm even learning some of the lingo. For me, Wife 1.0 was installed almost 36yrs. ago when they still used punch cards to program, no Child program would take. It was not from lack of attempted installation, but programing wouldn't stick. However, I will say that lack of Child 1.0,2.0 or 3.0 did allow for certain operational upgrades, such as larger storage space for wife 1.0, bassboat (1.0,2.0 &3.0), MiamiViceCar 1.0, and VX 1.0. So even though I'm operating an antiquated system a little Metamucil 3.0 keeps it running smooth.
