Copy of the v2.1 ROMs from a Radius 16 Accelerator for a Macintosh SE. Should also work on the 25MHz version. These ROMs are the last version made by Radius, and allows booting System 7 and System 7.1. Earlier versions of the ROMs only supported up to 6.0.8. Both ICs are 27C256 EPROMs, and are easily available today. ROM dumps are 1:1 of the original, and should be ready to burn onto a new IC.
Emulating this? It should run fine under: Mini vMac
