Recreating a HP-25

[Alejandro Paz(Germany)]

These last days I was able to get to work again on the core, and to iron out those bugs that prevented STO/RCL and the block-memory based register file to work. I ended, as I suspected, having to add a couple extra cycles to account for the block ram latency. Now, it works as a real 25 would do but much faster. Sadly a bit late for the meeting .

Now I have a question, is the firmware of the 25C different from the regular non-C model ?
