I understand it. I want to create a new PCB with new ROM chips.
I don't know if it is possible to read the original module from HP ...
Theoretically, yes there were some tools floating around for 2.11, but I don't ever recall any being compiled for 2.00. If you're pulling the chips and have the tools, it might be easier to perform a block read using an external chip reader?
There might be more fun had in trying to spit Linux or even CE 3.00 onto it, rather than CE 2.00.

Would a 660lx rom card work on the 620lx? This might be an interesting alternative
No the interface was different, sadly.
