what happened is my MPC?How to Fix up?
I think it is OS trouble, But what can i do?
Help me!!!
It is not OS trouble.
More like scrambled workspace/parameter/NV-RAM as a result of booting to the new OS from a VERY old version.
Or some other co-incidental failure of a component within your MPC3000.
1: FROM THE DOCUMENT that comes with the 3.16 floppy boot.
"The MPC3000 may have a ROM version installed in ROM that is older than version 3.11."
Solution if you want to run the newer version of OS ... The set of ROM chips will need updating.
2: MPC3000 machines fitted with older versions of operating systems ( previous to 3.11 ) are known to have trouble booting into newer operating system versions.
3.00, 3.03, 3.08, and in some cases, 3.10 are known to have troubles when booting to version 3.11, 3.12, 3.14B, 3.14 and 3.16.
A problem related to the buggy boot loading and system init code present in older OS versions.
In an attempt to fix the "noise" you are experiencing.
1: Re-init all user parameters.
2: If this has no affect then the machine will need to be opened up with the power off and disconnected to perform a short-circuit reset of the workspace/parameter/NV-RAM battery.

BTW: How much RAM is installed in your machine ?
