A friend of mine just learned of a Signetics chip for the 68xxx series, the 68905 Basic Memory Access Controller. He thinks this chip is a cache/MMU controller for 68000's and 68010's. Does anybody have any of these guys sitting around that they'd like to sell? Data books would be nice too. He is also looking for data sheets for (I think) a Signetics 68450, which I think is a floppy controller with built-in DMA. (Hope I'm not confusing that number with the DMA controller. :-) Any replies can be sent to Mike Stroven: ...!uunet!sharkey!anet!mist mist@anet.ann-arbor.mi.us or if all else fails, to me and I can forward them. Thanks. -- --**-Steve Barber----steveb@shade.Ann-Arbor.MI.US----(cmode)-------------------
