[rescue] [OT] S: IBM /370 or /390 card

That just doesn't sound right - if IBM could make a meaningful 370 mainframe with the 68000 CPU, why would they continue using all those zillionsvof 'modules' to build up a mainframe? Tradition?

The I/O system in a mainframe is where the value is, not the CPU (for common business applications, not scientific computations)...
