IVS or ICD just announced a 14mhz 68000 chip in the current Compute!. It has
a standard 7 mhz software switchable option.


What is a SCSI controller?

It usually handles 8 hard drives. It allows some hard drives to autoboot.
It often contains on board ram to be used as a buffer or cache. It may also
work with DMA, which means that it may or may not slow down other programs
that are multitasking when the drives are accessed. Many controllers often
have sockets or SIMMS for up to 8 megabytes ram. The type of controller as
well as the drive speed will make programs load faster or slower. Many
controllers also provide a place to mount the hard drive; otherwise you 
would have to use a disk drive bay (on a 2000/3000). I hope that this info
is helpful in your search for a hard drive, and if any info is incorrect
please feel free to tell us. :)
