Another *BIG* question is: memory manangement for HOW MUCH memory? If it won't allow direct access to at least 4Mb, what good is it? Right now, my next system looks to be a 68000 running CP/M-68K. It may not run Z80 code, but i won't run short of memory any time soon. Come to think of it maybe Tandy has a good idea in their model 6000; it has both a 68000 and a Z80, although it isn't clear from the description whether the user has access to the 8 bit processor or if it is a dedicated i/o device.

It was a dedicated i/o processor, and tandy does not give out ( or make available) any info on how to access it. -alex p novickis -- UUCP: {ihnp4,ames,qantel,sun,seismo,amdahl,lll-crg,pyramid}!ptsfa!nonvon!apn {* Only those who attempt the absurd ... will achieve the impossible *} {* I think...
