- Since you posted it twice I have to ask: Is this your homework?
-
- If yes then: DO IT YOURSELF!!
-
- If no then: Sorry, I don't know Intel. (I *THINK* you're talking about a PC)
-
- Bzzt! Thank you for playing. IBM doesn't just make IBM PCs. In
- any case, the 80x86 is not microprogrammable. It may be
- microprogrammed, but the control store is definitely not
- writable.
-
- I suspect that the questions apply to IBM's most famous series of
- machines, the 360/370 series. If you thought them placing
- increasingly souped-up versions of the 8088 in IBM PCs was bad,
- note that the 360/370 series has been using the same instruction
- set and processor architecture for nearly _30 years_. IBM's
- top-end mainframes (like the 3090) still run IBM 360 programs in
- binary form.
