It's also
that this is the 'classic computers' list. To me, classic
computing means
rather more than just the hardware. It also covers the design and
construction methods, technology and so on. And there seems to be
precious little of that in a modern microcontroller acting as a clock
oscillator.
There isn't., but some-times we have to compromise, and sometimes we choose
to compromise. I looked at the circuit of the M484 and I might not have the
parts in the parts box... .. its also a nasty hybrid design with DC biased NPN
and PNP transistors. I
find it ugly and can see it being a pig to debug, though it simulates fine
in LTspice...
I didn't find it that hard to basically understand in my head. After all, there
are only 4 transistors, and 2 of those are just an output buffer. Quite
why having both NPN and PNP transistors makes it harder to understand
I do not know.
I will leave the flames about Spice and simulation packages in general for
another day.
