As I have mentioned, the c= apabilities of the tester are fantastic I have some questions and would like= your thoughts on a couple of things- I couldn=E2=80=99t find them, are schematics available? What are your thoug= hts on releasing them? Finding the chip in the menu is inherently difficult, a small screen and swi= tches just isn=E2=80=99t the most efficient way of finding something.=20 What do you think of also allowing chip selection via a simple unique chip I= D rather than chip mfg number. e.g., xxx-yyy and pretty much sequential wit= h no relationship to chip number. It would allow a quick and thorough part n= umber search of the master PDF on the computer, and then would speed up sele= cting component with just ID number. A means of communicating with the tester from the computer would have been u= seful. I am wondering why you decided not to include an interface. Even a s= erial port and terminal would be advantageous. If the hardware isn=E2=80=99= t there, it may need to be a daughter boards at this point, or use the memor= y card slot.=20 Do you have any plans to test more sophisticated chips and processors F8, 80= 08, 8080, 4040, 4004? I guess I haven=E2=80=99t searched to see if it can d= o any cpus or programmable support chips like UART and programmable IO.
