I think I'm missing something obvious. I just bought another 41cl module and I was going through the manual to figure out the exact differences between v2 and v3 of the hardware. At the top of page 21 of sy41cl_v4.pdf, ADV1 and ADV2 are the Adventure ROM, parts 1 and 2. I don't remember ever seeing an Adventure ROM for the 41. I checked my HP41C 30th Anniversary CD from TOS and I could find no reference to this ROM.
What am I missing? This is really bugging me now.
