Is it true the TTL System 1 main board doesn't run all the later carts? I find that a bit surprising given that the kit manuals don't mention any compatibility issues.
However, I found a post (here) that indicates a modification is needed. I've posted it below.
1. Cut and lift 14M pin 6, connect this lifted pin to 14M pin 16. (+5V).
2. Cut and lift 3D pin 11.
3. Connect 3D pin 13 to 4A pin 5.
4. connect 3B pin 13 to 4A pin 6.
5. Connect 3B pin 12 to 4J pin 12
6. Connect 3B pin 11 to the PAD of 3D pin 11.
Anyone know about this? Also, does it prevent anything from running (such as the original cart)?
