Day six came and went with me not doing the learning challenge at all while I put together the latest episode of Open Metalcast.
Day seven was a little more productive with playing around with BEQ some more and realizing that I'm going to get the most out of entering these programs on the Apple ][ until I get more proficient with assembly code. Unfortunately one of the exercises required paddle controllers, which I don't have on this emulator (not sure how to fake them either). So I didn't play around with the exercise itself.
The chapter finished off with the transfer commands (TXA, TAX, TYA, TAY) which transfer registers between each other (TXA swaps the X register for the Accumulator, etc.).
