Thank you, that's very helpful.

Thanks, I will give it a try then. I'm going to install dip sockets first, just incase they don't work. My other questions now is how do I configure the jumpers for the extra ram? Is there a guide on these jumpers?

Thanks

I just picked up a Commodore Pet 2001n with 16k and I see that there is a whole empty ram back to add more memory. The current memory installed is TMM416D-4 , but I have 8 ram chips form my old TRS-80 Color computer (8040016). Will I be able to use the 8040016 ram chips on this Pet?

Thanks

Brian
