I was looking around at the bboards, and saw this message, and saw it hadn't been replied to, so... The 68070 _does_ exit, but it's not a motorola chip. It basically a 60000, w/ * Full bus error recovery * decoded interupts * built in clock generator * MMU * 2-channel DMA controller * I^2C bus interface (up to 100Kbits/s) * UART interface that can use an external clock * 3 Timer registers There's alot of talk of this chip going on on internet.coco, since it's being used for the MM1. Why do you want to replace it anyway? It's actually a bit slower (15Mhz '70 = 12.5MHz '00). Granted it has some very nice additional features, but I'm not sure how you could reasonably change your system to take advantage of them. ----------------------------------------- David Faler Carnegie~-Mellon ~University df1m+@andrew.cmu.edu "It is not just a riot of blots and blurs and disjointed jottings linked by spurts of speed. . . it only looks as like it as damn it." - James Joyce Disclaimer: "Consistency is the hobgoblin of small minds." - Ralph Waldo Emerson
