In a way, I suppose the disk controller was a clever

locked the CPU into 2MHz operation. The use of a simple arithmetic
checksum for each sector was not perhaps the most reliable solution
either. But the biggest problem is that disk reading and writing
required 100% attention from the CPU. On most other computers that
used dedicated LSI controllers, the possibility existed for
overlapped computation/disk access.
Like when?
I can't think of any small computer or PC that does that?
