• Entering '(0,1)' onto the stack and then pressing EVAL returns the list { '0' '1' } rather than the complex number (0,1). This may or may not be by design, but it surprised me.
• Entering 'sqrt(-2)' onto the stack and then pressing EVAL crashes both the physical calculator and the PC emulator.
  

Both of these operations are carried out with the complex results flag checked.

I haven't used newRPL for a while and it is wonderful to see how much progress has been made. George R R Martin could learn a thing or two from Claudio!

I updated the unofficial ROMs with a few bugfixes, I believe the crash you mentioned above should be resolved.
Also, complex numbers can't be expressed with parenthesis in a symbolic. You basically called a function without any name or command, therefore the list of arguments was returned as it was on the stack. This is part of the not-so-new support for multivalued functions in a symbolic. You can return multiple results and will be packed into a list.

Edit: Just for completeness, to express a symbolic you need to use a+b*i where the complex i is not the letter 'i' but the one on Alpha-LS-7.
