What is the feasibility of porting Minix to a new platform? Specifically, I have an Old Box, (Callan 100) with a 68000 CPU board & 1Mb RAM on a Multibus. It runs (ran?) System III unix. What are the chances of getting say Atari Minix code to compile? I realize that I will haev to re-write the portions that are in assembler, but as I already have a functioning unix system within which to work, it doesn't seem too daunting. If I am all wet, plz tell me. Also, as a side issue, what would the benefit of replacing my 68000 with a 68010 be? Thanx, -- Dave Strout -> The above ideas are mine only, unless you like them.

It is no problem to port MINIX to another 68K box. You will have to rewrite the device drivers. The assembly code stuff needs only pretty slight changes. The 68010 comes along with a different exception stack format for bus and address errors - not too compilcated to change this. C.v.W.

To port MINIX to another 68K box, would one have to purchase a copy of ST MINIX if one already bought PC MINIX 1.5 (PH)? Neville Chandler

If you have only PC MINIX and want to port it to a 68K box, locate a ST MINIX owner close to you. If you cannot, you have to buy ST MINIX -- I think only the kernel sources are affected. C.v.W.
