When you say you're not likely to get 128 meg and an 040 onthe same card, what kind of chips are you thinking of? 4M or 16M? Granted, the 16M ones would cost more than one would care to admit (your comment about mortgaging the house was quite humorous), but it would be way-cool to have an 040 with it's own super-fast ram. Also, how much room would you feel would be left over to external caches? >can realistically fit 64MB on a board. If you went to 16MBit DRAMs, like used >on those 16MB Mac SIMMs, you could fit 256MB per card. Those chips do in A 256MB card would be a real dream. I tend to live in RAM: for most of my work and temp files, and a board like that... (now to win a lottery so I could afford to pay for half of it) >Yeah, you can add another 8 MB of 16 bit RAM, and yeah, it will be slow. It should be pointed out that you can only do this one, though, as the Zorro II autoconfig space is still limited the same way it is on an A2000. And if you want a bridgeboard then you can only add another 6. Seriously, though, due to speed I wouldn't consider this an option. If one could tell RAM: which board to allocate from, then maybe, but otherwise, no. -=> CAW Christopher A. Wichura Multitasking.
