As an adolescent, I wanted to have a relationship with Spectrum. However,
I ended up jumping from one computer to another, learning things in a
process. By the time I settled with Amiga few years later, I had already
known three and a half programming languages (and heard this or that of
few others). Paradoxically, having my own hardware dumbed me down :-). And
this state of mind persisted up to these days.
BTW, Commodore PET turned 35 in January and Amiga 1000 will turn 27 in
One thing I like about old machines is that they were selfsufficient. They
came with tools, so every owner could plug them to the wall and start
writing software for himself.
Nowadays - Arduinos, which are barely comparable to various ZX models,
but with pitiful amounts of RAM... Ip(h|)(a|o)(d|ne)s, with no onboard
compilers nor interpreters at all... Cellphones, at least, have one
limited Java version - but, well, for me it is twelve years or more since
Java stopped being sexy. OTOH, it is better to have it than to have not.
Fortunately, PC is still in use. And Android tablet can be supplied with
keyboard, so at least in theory it can be converted into normal computing
device, capable of serving its own needs. And if I really wanted, I can
have something more hardcore, like BeagleBone (but I don't think it could
be bootstrapped without PC).

I read this about every older computer from time to time. Some of them
have been first programmed by some legendary engineers, who sat in front
of the panel and typed in hex or binary from their memory.
A similar contemporary effort is, for example, Scheme-from-scratch:
Note the guy advises using DOSemu for DOS thing, because under newer
Windows one supposedly couldn't do such interesting operation as entering

While reading Jon Bentley's "Programming Pearls" some 15 y ago, he made
one fancy remark, something like "today, people say like, one megabyte
here, one there and now we can write a program". It is "gigabyte there,
gigabyte here" nowadays.
Weeeell. I sure can find a good use for a gigabyte. And I won't mind a
terabyte a bit later. And while most programmers are spoilt by "free"
resources, there are some who enjoy optimising, so let's not worry too
much. After all, there are only 10 kinds of programmers and the zero kind
is still possible to be found.
