Given that
there's a limit on the number of transistors, I don't
see what
advantage using SOT23s would give you.
It'd be easier to assemble.
Only if you don't spend hours looking for the transistors that flew off
the end of your tweezers :-).
My point is that while SOT23s didn't exist 40 years ago, there is no real
reason to prohibit them in a project like this. Limit the number of
transistors, sure. Insist on an architecture that could be built 40 years
ago, sure. But should the use of a storage 'scope to debug the thing be
prohibited too, on the grounds that hobbyists 40 yrars ago were lucky to
have _any_ 'scope? Do you prohibit writing simulators for the
transistorised machine, on the grounds that 40 years ago hobbyists
wouldn't have had anything to run them on?
