Given the prices on his cards, it hardly seems like a bargain. If one wanted to goof around with the Z8000 family as a coprocessor card, I'd be sore tempted to wire up something with a Z8002 and 64K of SRAM. You get the instructions without the expense and you don't have to deal with the (awful) Z8000 segmented mode. And relatively easy to do a lashup. Instead of Ciarcia's bucket, you could probably do with a single Z8036. Fit the whole thing on a "short" card. IMOHO, only Motorola and NS of all of the "16 bit" chip producers ever understood the importance of a continuous non-segmented memory space. Given the time of introduction, I consider the 68K to be a marvel of MPU design. Too bad IBM didn't adopt it for the PC. Cheers, Chuck
