Ok, Grant. Let's go all the way back to my original email. I assumed a NORMALLY
clocked TI92, and have specifically said "10 MHz" and "normally clocked" in every
email since. Sure, with a 30 MHz TI92 I am sure that transfers of that speed could
take place.
Let's stop here and start over. Even through much miscommunication, I think it is
clear that 1.7MB per second or 7.5MB per second whichever it may be is considerably
faster than 5KB per second, would you not agree?

That would be good.

Um.. A 68000 uses 4 clock cycles per bus cycle. Another embedded thing?
