My first system was, IIRC, an Intersil 6100 (single-chip pdp-8 clone)
that my Dad designed and I wire-wrapped. It had a four digit LED
display and a keypad. I wrote my first real-world-affecting
program on it by using a 74c06 as a speaker driver, controlling it
with a single bit, and then flipping that bit with a hand-coded loop
to make all kinds of sirens. Good times!

Aaaaaaaaaaargh, I had an amp from an established company, can't remember
this company, everything was connected by wire-wrapping, so indeed a
good discrete circuit, but the wire-wrapping did cause defects. Btw. I
prefer good old leaded solder, but leaded solder in Germany isn't
allowed anymore. We should start to wire-wrap all electronic devices for
our politicians here :p.

The amiga
is actually fairly late model here folks, I started with a quest
super elf I built from a kit. Circa '77.
1802 CPU fan here too. Mine was RCA COSMAC VIP 1802.
Added 3 channel sound (Famous G.I. AY3- chip) and
colour graphics with T.I. 9918 chip, after read Circuit Cellar article on it.
Oh what fun...
