I was thinking the system might be better without without the 3081+3730.
Would a plain mips 3000 40 Mhz + 3010 be cheaper???
AAAARRRRRGGGGHHHH!!!
A raw R3000/3010 requires several carefully timed clock inputs. One of the
BIG advantages of one of the second generation chips, like the R3051/3081
is that all the grotty clock generation is on chip, and the chip takes a
simple, single-phase clock input. I've heard that MIPS had trouble building
R3000 based systems at >25MHz; there's no way I'd try to do a 40MHz system.
Of course, some of the folks on this list may be more macho than I.
<soapbox mode on>
The only way I can believe this project might really fly is to stick with
easy to use parts and keep the design simple. Otherwise it will never get
done.
