Agreed, it should work as a '10 on a 20 board' but I just need to be sure.
Check with the man himself. A few days back he was clear he won't do partial assembly - but on the plus side confirmed he will do 10. However, will you have to wait for a Bitburner X or get an underpopulated BitBurner XX? Only one man knows the answer to that.
I can buy 15 chips more from zefir and I'm not sure if it is possible for a 20 chip board to work with only 15 chips placed on it.
Basically Im asking if it can work underpopulated and add later 5 chips more.
I won't do partial assembly, either 10 or 20.
