Hi MenguinPonkey, thanks for the skull for Risc Relay computer.

I had a look at SAMIRA, and I do not see a mode for indirect data store/load. I think such a mode would make programs a lot simpler.....

  Are you sure? yes | no

hey, yes that's correct but my goal is to keep the hardware and soldering effort as minimalistic as possible and implement most functionality in software :)

  Are you sure? yes | no
