I wasn't familiar with the design problems of the mips 3000.
How hard would it be to just replace the 3730?? So we save $130 and can
use the 36 bit simms. I would think the 24 k cache would make the
interleaved memory even more important.

I agree I think the ide+floppy+uarts+parallel+game should go on the ISA.
