Since the Super 8 bit does have a large, dust unprotected opening in the top, I decided to finally do something about it.
Soon I'll have 3d printed dust covers in a choice of 4 colors that will protect the cartridge connectors from dust and look nice when the system is not in use.
These covers shown are just prototypes, the finished ones won't have any openings.
These "dust plugs" will be included with all Super 8 bit systems and available for free to anyone who has ordered the v2.5 or v3.0 Super 8 bit system previously.
Right now I have black, white, red, blue ABS and semi transparent PLA.
I've tested the component video add-on board made by Viletim, but it didn't work well with either of my flat screen TVs I tested (the TVs didn't handle 240p component signal well.) I decided not to include this in any Super 8 bit systems as a result. I find the Jrok component video converter is currently the best option.
All my v3.0 Super 8 bit systems are v1.7 NESRGB. So I guess it's safe to say 100% compatibility for the system then. Cool!
