Post subject: | The RETROF series of homemade TTL computer. |
In Japan in 1978 Gataro Sido attempted to make a computer with TTL, the RETORO-16. http://tiny.cc/acmjjz Quote: 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. 2012; RETROF-16. http://tiny.cc/9dgkjz 2013; RETROF-16A. 2014; RETROF-16H (http://tiny.cc/54fkjz) and RETROF-SXGA. 2015; RETROF-16K. http://tiny.cc/mjokjz 2016; RETROF-16M. http://tiny.cc/ofmjjz 2017; RETROF-16N (abandoned), and RETROF-16R. http://tiny.cc/aemjjz 2018; RETRO-2020. http://tiny.cc/xpmjjz |
