I know it's expensive but it's good (I don't know whether it's 200 pounds good however) IT's got a 16K (or is it 8) data cache to give it some speed. It also has a slot for a 68881 and slots for the TOS1.4 roms so that ROM routines will be run at full speed. They're meant to be bringing out a 68030 hypercache soon, but I don't know much about that one. I was toying with the idea of buying a hypercache to speed minix up a little, but I don't think it's worth it. Maybe I'll just buy a 33Mhz 386 and be done with it :-) (Running Xenix of course) Kevin Maguire Nsfnet : sa44%liv.ac.uk@nsfnet-relay.ac.uk Uucp : ...!mcsun!ukc!liv-ib!sa44
