A new RPL firmware for the 50g

[Paul Dale]

Isn't the purpose of implementing RPL so that many other functions can be written using RPL? That is the purpose of system RPL. I agree with Thomas, though the comments are vital. Still, they are just programming languages.

Having said all that, I think you are underestimating the difficulty of writing the 800+ functions. Writing accurate and reliable numeric code is hard. Emulating the odd behaviours in existing functions will be fun too -- I've a recollection that free42 located a number of bugs in the HP 42S which had to be emulated.

The low level hardware driving is the easy part to my mind. At least the fun doing the GC is recognised -- calculators require a compacting collector, not just the free all unused memory style collector or reference counting collectors.
