Theres' a partial clue in clockspeeds: Back in the day when the 8-bit
chip was king you could fairly easily build hardware with an ordinary
soldering iron and debug it with a logic probe and a multimeter. If yo
think you must have a 'scope as well, then a dual channel 10MHz one will
do the job easily.

The kit needed to assemble SMD starts to get more complex and rather
harder to use and the sort of scopes and logic analysers needed to debug
hardware running at a GHZ or so, i.e. a Pi Zero or equivalent, are much
more complex and expensive.
