In the chapter on RAM, it says we can index upto 64KB of memory in a 16 bit architecture. Shouldn't it be '128K words of memory', since we can index '2 words' with a single bit.
You are correct, the text is wrong. It should be 128KB, not 64KB. A word is two bytes (on a 16-bit architecture) so we can address 64K words which is 128KB. (I think you mixed up byte and word in your comment, but I understand what you meant.)
The explanatory text for the level does not really define neither "byte" or "word", so beside fixing the error it also need more details. (But I want to avoid going down the rabbit hole of explaining that bytes can have different sizes than 8 and so on)
