I am expecting literature from them next week. I'll tell you what little I learned from their sales rep on the phone yesterday, though. Price for init + 68851 MMU = $695 Price for init alone = $295 The product is supposed to ship next week at macworld, there will be show special prices of ~600 and ~250 respectively. The init will supposedly work with any off the shelf 68851 so it would probably be worth shopping around. (This leads to the question of does anyone know sources for the 68851? I called all the places from the back of BYTE yesterday, ie JDR, Jameco, Microprocessors Unlimited, and they all acted like they had never heard of it.) Also, a special version of the init designed to work with the 030 (in the IIX and SE/30) will be forthcoming soon. The rep was unable to answer questions like "What's the page size? What's the page replacement algorithm?" Any additional info would be greatly appreciated.
