A few questions on the 68020: 1) Does anybody know when it will be available in commerical quantities, especially up here in Canada? What will the price be? 2) Will Motorola have an MMU out for it? What will the cost be and what will it do? 3) Is there a version of OS-9 specificly for the 68020? Where could I get source code or a generic system for the 68020 or the 68000? Thanks for any help you can provide. ===================================================================== Curt Sampson ihnp4!alberta!jeff --------------------------------------------------------------------- "It looked like something resembling white marble, which was probably what is was: something resembling white marble."

/***** uokvax:net.micro.68k / alberta!jeff / 4:44 pm Jan 31, 1985 */ A few questions on the 68020: 3) Is there a version of OS-9 specifically for the 68020? Where could I get source code or a generic system for the 68020 or the 68000? /* ---------- */ Can't help on 1) and 2), but here goes: so far as I know, OS-9/68000 Level 3 (the version that pages, which will want a 68010 or 68020) is not yet available. (Sigh; neither is Level 2, which gives each process its own address space with the aid of memory mapping hardware.) As for source code or a generic system--you can't get source code for all of it. That's OK, though, because even OEMs don't get it; you don't need it. What you can get from Microware is what they call a "PortPak." This consists of the kernel, utilities, and source to what is supposed to be sufficient stuff to get you started on what is specific to the machine you want to port it to (e.g. sample device drivers, the clock module, and so forth). If you say you want to do cross-development from a Unix system or an OS-9/6809 system (I think you can do it from VMS these days, too--better check with Microware), you'll also get the appropriate C cross-compiler and cross-assembler. Price for said beast varies, depending on where you want to start from and whether you want it on tape or on disk; the cheapest is a port from an OS-9 system (I think it's $1K to $1.5K), and the most expensive is a port from a Unix system (I believe that's about $2.5K). The place to get a PortPak from is Microware itself.
