I just got my Apple IIgs RGB to Component adapter from Nishida Radio.
Here’s a little video review, but basically:
1. It works, and
2. GET ONE
Now I am confident I can continue to use real Apple IIgs hardware for another 30 years.
Nishida-san has really filled a HUGE need as CRTs are rapidly dying and the Apple IIgs RGB display has some quirky characteristics that make it difficult to use with scan-doublers and multisync displays (really low refresh rate being one).
Anyway, check out the video on YouTube and be amazed by Koichi Nishida’s work.
