CC1 and CC2 ROM chip compatibility
I bought a CC2 logic board with a burst of batteries. Burst isn't that bad, it looks like it can be rid of corrosion and repaired with some pattern modifications and parts replacement. I just finished repairing it modify the pattern in a few hours.

SO, There is one problem. Among the Hi and Lo Rom chips, "341-0533 Lo" has been lost.

I have both Hi and Lo CC1 rom chips, but they don't seem to be compatible.

1，The image below is the actual board. The rom of HI is stuck in the socket of LO, and the installation is wrong 8-o . Perhaps an unknowing person has done something.

2, This is the correct CC2 ROMs

3, CC1 Roms

Any thoughts on bringing this board back to life?

Or do you think I'm wrong and CC1 and CC2 ROMs are compatible?

are the 27c4000 eproms  and the CC2 ROMs pin compatible?

If so maybe you could burn a set of 27c4000 eproms with the CC2 ROM LO and HI

Houm... as I expected. Look for the junk board generously. Thx.
