So - can anyone explain
the difference, in terms that aren't too hard to understand?
The 68x09 (no E suffix) has an internal crystal oscillator circuit (pins 38
and 39) and generates the required quadrature clock (E and Q, pins 34 and
35).
The 68x09E requires an external quadrature clock input (E and Q, pins 34
and 35), and uses pins 38 and 39 for other functions (LIC and TSC,
respectively).
And - is
there any hope of modifying a machine that would normally require a
68B09E to be able to use a 68B09?
Generally speaking, no.
