Jim, I stumbled on www.classiccmp.org and noticed your reply to William Donzelli's post (yesterday): Is the FPU you're looking for the 68882? If so, I think I have one. I don't know what package types this was offered in, my vague recollection is that the one I have is about 1.5" square pin-grid array. Anyway, you're welcome to it if you're interested. In return (or in spite of this!) I have only one request: the FAQ link for the Classic Computing message board doesn't seem to work for me - I need it because I want to offer the rest of my old Apple hardware up for grabs, but I don't want to spam the list with things like: "I have a complete Apple][+ system with a fair number of expansion cards and Sider 10MB HD. The remainder of what I have is old Mac-era stuff, I think I have had to throw out all of my one-piece hardware (Pluses and SEs) but I have a complete Mac IIci, possibly a IIsi, and some PM6100 and Centris 610 form factor stuff that wants a home." Perhaps there is a subset of folks that are interested in providing a home to more old hardware? I'm located just north of Boston MA. All the best, Arthur
