Thanks for the tips. Cool upgrade board! But I'm just not that ambitious. As for cannibalizing an e.g., HP 21...weird...they go for such a wide range on eBay...so, maybe – if I can get a very cheap one. But given my 25 is also missing the case back, I doubt I'll expend much more effort, unless...a 21 has the same case! :-) Though if I ever do get the 25 working, I might make a wood back for it.
