Hi everybody,
I'm motivated to build a small batch of these cards if others are still interested and can loan their individual expertise. I can assemble the boards and fabricate the brackets if needed. I have limited experience flashing chips, but could probably figure it out if need be. I don't have the firmware. I'm a noob still and don't think I have the ability to ask Rio444 for his firmware.
I know There are a lot of other DIY solutions available but Rio444's is certainly the most elegant and, from what I've read, works the best.
I may end up building some necroware adapters too, but I still think a straight ISA card is cooler 😀
