If All 7800 use the same bios or at least the same code to switch to 2600
mode then
a signature check (or crc/checksum) can be done on ram.  Because the 7800
copies
128 bytes code to ram with the 2600 swiching code.

So you are saying if the 7800 leaves this stuff in the RAM you could poll it in the 2600 init code?
