2. What was an AC128

3. What does TQFP, BGA and SOT refer to ?

4. What does EN60950-1 standardise ?

5. What is an ARM9 ?

6. What does this mark mean



7. What is (was) the Morse Code for 'S' (Random old timers question)

8. What did Barkhausen say about oscillation ?

9. What is the R&TTE Directive ?

Correct. Strictly speaking it is a microprocessor core which is now used by ST, Freescale, Philips, Atmel and even Altera in softcore format. To name but a few.
