Hi David,
The irony here is that the things you find troubling are all provided by
microprocessors and DSP within the radios and displays. So you DO have
computers in the shack, I think I count at least four, and there's a
separate microprocessor in the SVGA board doing it's own higher
resolution FFT of the K3 IF. So that makes five. :)
As a side story here -- in 1982, I bought a very expensive, very
advanced piece of audio instrumentation called a TEF Analyzer. It was
made by Techron, a division of Crown, and it was dedicated to Time Delay
Spectrometry. It contained three Z80 microprocessors -- one generated a
swept oscillator to excite the sound system, a second a swept oscillator
for analysis of the received signal, and the third operated as a
computer to control the other two and provide a user interface. The user
interface was written in SBASIC, so that advanced users could write
their own code, and I once took a class to learn the fundamentals of
doing so.
The operating system was CP/M, similar to DOS, and it ran DOS programs
like word processors, databases, and spreadsheets, and I used it for all
three functions in my small business. It was my second programmable
computer -- my first, about four years earlier, was an HP41.
