Is an MMU'd version of the 332 ever going to exist? Does it allready exist? Thanks. <tdr. -- SunOS 4.0.3: /usr/include/vm/as.h, Line 44 | Theo de Raadt Is it a typo? Should the '_' be an 's'?? :-) | deraadt@cpsc.ucalgary.ca UFS semantics! UFS semantics! UFS semantics! UFS semantics! UFS semantics!

I'm not sure if you mean an MMU on board or what, but why would a 68332 need an MMU? It's not really meant to be used in that mode. Using the programmable chip select pins are a god-send for embedded systems where the 332 was meant to be used. I would imagine that if you were to not use any of the chip selects so that the original functions were available (all those extra address lines and bus control signals) then you could use one of the available MMU chips out now. Why would you want to? Not using the chip selects is like cutting off your legs so you can enter a wheelchair race. You could do it, but you really shouldn't be in that race to begin with. >SunOS 4.0.3: /usr/include/vm/as.h, Line 44 | Theo de Raadt -dave -- Dave McMahan mcmahan@netcom.uucp {apple,amdahl,claris}!netcom!mcmahan

I believe the version with an MMU is called the 340 and I think it is available now. later ron -- Ronald D. Shaw shaw@plains.nodak.edu (Internet) uunet!plains!shaw (UUCP) shaw@plains (Bitnet)

The 68340 doesn't have an MMU either. It has a different set of I/O capabilites than the 68332. I don't have the specs here, or I'd post more info on it. -- Eric L.
