@Stephen @JDW
JDW's Youtube work seems to have energized Vintage Mac users and praises it.
I would like to summarize our story so far. Stephen and I were in contact outside of this topic on another matter.
I talked to him, but I think I'll probably use his PCB from the first badge. He will put in a custom silkscreen for me. You need to check if it works, but it will probably work.
What we did:
・By shifting the positions of the 512K / 128K ROM pins, chassis interference is avoided.
・I especially want to have a low profile, so I'm thinking of using a custom pin made in Japan. The parts will be expensive and the profits will be even thinner, but I don't care
・Rom chips are shipped with BMOW Rom pre-installed. we also have another custom chip with SYSTEM 3.2 installed that allows 128K booting. The user can choose this.
・Steve Chamberlin and I have already talked and have a license to make it possible.
