I have no experience with the HP67 myself (I own one now, purchased on eBay, but couldn't have afforded it back when it was new), but I do have experience with the HP19C, which is very similar. Both have only one "indirect" register, which makes a lot of algorithms awkward to implement, always having to shuffle things around to get the right pointer into register 0 (which is the I equivalent on the 19C and 29C). Compared to that, programming the 41C, where every register, even the stack registers, can be used for indirect addressing, is so much more pleasant, and the 42S inherited that programming model.
