HP calcs with clock

Most of the capability is there, but requires extra software to do it. It has ON TIMER# for example which can also wake the machine up when time to do something. There's CLOCKLEX (if I'm remembering the name correctly-- I merged a lot of my LEX files into one) which gives the a running time display in tiny characters in the LCD while you do other things, unlike the 41, using CLOCK ON. CLOCK OFF turns off the tiny running clock display.
