I found a 4K NTSC BIOS and 16K PAL BIOS at:
using a hex editor and Keith Henrickson 7800 bios disassembly. I found and
verified the code that is copied to ram. The first 100 bytes are identical
for both
versions. so a signature check on (part of ) them is possible.

Hmm, I just realized though that the test won't work when using a
cuttle cart or other cart that overwrites Ram before the test can be made.
