Hi, William! Thanks for your interest in #Opamp building blocks!

  Are you sure? yes | no

Mitsuru Yamada wrote 12/01/2022 at 01:16 • point

Thank you for liking my #6502 standalone computer and #PERSEUS-8 homemade 6502 computer ! PERSEUS-7 is using for basic computer training.  For PESEUS-8, I built my own floating-point interpreter and was also used as a development emulator for PERSEUS-9, which was built this year.

  Are you sure? yes | no
