Good concept, but the downtime between available researches is high. Maybe some more options to make different CPU's like instruction sets? I will play through it some more, but for now the winning formula seems to be easy. Just make the best thing you can, and release it, make it again and again untill a new research is available.
There is a writing fail in the window for when you release a new DIP processor. It say's DPI. I hope this game turns out well :) I am looking forward to it!
EDIT:
I have ran the game for almost 10 years without an research available. I would love to see an update to the game :) You are certainly hitting some good notes with it! Keep it up!
