The 3eeee ROM is built from a 2CDCC dump, with patches.

I looked for the 2CCCC IDS document for a long time, but never found it.
If ever someone have it , or a copy, I would still be very interested !

Fortunately, the 1BBBB and 2CCCC/2CDCC versions are close enough to be able to modify the code with the help of the available IDS for the the 1BBBB .
