ウォズニアックを軽視するものも多いようだが、コンピューターの黎明期に子供時代からCPU/ISAを自作するなどしている

The cream soda computer was before useful microprocessors so I created the processor itself out of TTL chips.
This was an era where shift registers, counters, ALU’s were around in 4-bit flavors. In the end, I added chips to
play with this simple 8-bit processor, just like the Altair, although I had no expansion bus that I can remember.
The start was to create an instruction set. I used two common 4-bit ALU chips, I think. The minimal processor
of this sort needed some arithmetic commands and at least one branch-on-condition. I created instructions
that were either arithmetic between the one register and memory, and at least one branch or zero or branch
on overflow instruction. Not much more as I recall. I was able to enter a program which took a 4-bit number in

福沢諭吉の故郷の中津藩みたいな田舎だと官学の朱子学が力を持っていたから、
李氏朝鮮や今の韓国みたいな無能な世襲と血縁社会だった。なので、朱子学中心
だと文明開化が発達しない。技術者が大事にされない。腐れ儒者と無能な両班が
村社会を牛耳る。脱亜論は朱子学否定なんですよ。

李氏朝鮮の朱子学な世界に近いか。

At school he routinely won science competitions, one of these for a device he built to show the atomic structure
of all ninety-two atoms in the periodic table. He later explained that he had thoroughly learned all the features
of a diode to make the circuitry work.
For another competition he produced a tic-tac-toe, or noughts and crosses, device completely designed around
the capability of logic circuits. Earlier we saw that Bill Gates wrote a tic-tac-toe software program in 1968 at the
age of thirteen. Wozniak built his hardware device when he was a year or so younger.
In the eighth grade, aged 13-14 years, he developed a rudimentary computer that he called an Adder/Subtractor.
It was a complex device consisting of a hundred transistors, two hundred diodes, and two hundred resistors with
