Hello, just wanted to share I've uploaded the v2.1 ROMs for the Radius 16/25 accelerator for the SE. I've not found another copy online, so hopefully this helps someone who wants to run Sys 7.1/7.0 on their SE with Radius card.

Cool, I'd like to imagine an interesting modern use for that. The Radius cards sure do seem to be the most popular to have comprehensive information on them. My Macintosh SE has a Megascreen 3 video card that does without ROM chips and relies entirely on software drivers to set it up. Unfortunately, the original owner didn't give us a copy of the drivers when it was bought/sold in 1997.

Correct me if I'm wrong, but the only proprietary part of the accelerator boards is what's on the ROM chips isn't it?
Could you theoretically reverse engineer your own accelerator boards with off the shelf parts and a PCB?

Could you theoretically reverse engineer your own accelerator boards with off the shelf parts and a PCB? The only other part would be getting the GAL equations, as it has a handful of them on the board. Apart from that, you could probably figure it out if you had the time and clone it, although I'd imagine you could greatly simplify it with an FPGA.
