partial P112 kits

That is basically how I feel to. If I didn't want to assemble it myself, I'd buy a ready-built <foo>, The point of buying the kit is to have some fun putting it together (which is a relaxation for me). And SMD work is not that difficult. As I mentioned, the one time I did find it _mildly_ stressful was when I was upgrading somebody else's HPO42S calculator [1] and was being photogrpahed using flash as I hand-soldered the new RAM. It still worked first time. [1] The HP42S came with 8K of RAM. It's possible to remove the existing RAM (a 6264) and replace it with a 62256 to get a 32K machine. There's one so;der=blob link you have to move too. There are some pictures of doing it (not the machine I mentioend above, another one I did) on my flickr site. I generally call the upgraded machine an HP42SV by analogy with the HP41CV. It's unlikely I would consider any such kit to be a sensible use of money at the moment, alas... -tony
