I have patched pc-minix up to 1.5.0 on my sun, i have not yet installed it on a pc. For our 68008 minix version we plan to buy atari-minix and start from there. To simplify the software labour we want to design the 68008 card as atari- compatible as possible. I have a few questions to those of you who have looked more deeply into minix-68k and it hw-needs. We are thinking of building the card with the following memory map, how does it compare with atari? f0000-fffff bootprom and monitor 64Kb e0000-effff i/o 00000-dffff RAM (bootprom shifted to lowest address during first 8 cpu cycles after reset.) I/O 68681 two serieports, our monitorprogram supports this chip what serialports does minix68k support? 2797 WD floppy controller, what does minix68k support? TIMER What rate of clock tick is minix68k setup for and what chip does atari support? SCSI We have not really been thinking of this yet, how is it implemented in atari. What memory adresses does atari use for it's periferal chips. Can atari minix diskettes be read by any other computer than an atari, we would like to get atari 68k src to a sun for patching and archiving. Can a PC read the atari minix diskettes? Can anybody supply us with the gcc 68000 crosscompiler for minix on a sun? We do not have ftp access. If you can help us please respond.
