Although this was the first time I tried to make my own computer in earnest, I had no basic knowledge at all and turned it into garbage.

1989; he tried again with the RETORO-16B.
Quote:
There is a memory that worked well only for fetching instructions, but it was turned into garbage without finishing.

2011; he completed the RETROF-8 (http://tiny.cc/y8ekjz), as well as the RETROF-BB and the RETROF-VGA.
Quote:
This machine was completed in August of that year, and has the performance of requiring 100 digits of pi even though it is 8bit.
