I was about to ask this very question. I have a Motorola 68030 currently soldered to a Macintosh LC II motherboard and a 68881 math coprocessor I bought on eBay. I'm designing a system as we speak based on these two chips. I was hoping to find spares for these or hopefully the 68030 in a PGA package. Rochester Electronics has everything, and while pricey, I just don't need two extra processors or four coprocessors. :/ *sigh!* Having a love of retro computers can be depressing at times.
