Okay, so I have an idea for my 1802-based homebrew system. For the ROM and NVRAM/Expansion-ROM, include some type of check value to ensure the contents are valid on boot-time, so that it can inform the user of an error. Boot-ROM failure will throw up an error message and halt, NVRAM/expansion-ROM error will throw up the error, but still boot normally. Might also adopt this idea to my Z80 homebrew.
