I've submitted data to him for a hundred or so DMGs...

it doesn't seem to pop up in his "started topics."

I think nitro attempted to do this once as well, you might try to combine data with him.

Can we get the table BBC code added to the forums? I can not believe it is not in use already...

Lets clear some things up. There are many revisions of the Gameboy's z80 CPU, DMG, MGB, SGB, etc. The point of this thread is not to make claims of which sounds the best and which can or cannot play back the best samples; that is for another time. The point of this thread is to categorize information about the CPU's themselves. Manufacturing data, revisions, etc and to set up a basic time frame of when each individual CPU was produced and to what degree each revision was made.

I am going to rely on the input of all of you here. I need for you to probe inside of your gameboys, gameboy pockets and maybe even super gameboys and jot down the text inside.

If you have an Original gameboy, DMG-01:

• The Letter after "DMG-CPU"

• The revision of the CPU printed at the bottom of the back PCB

• The Region where it was manufactured, Usually if not always Japan

• The Time stamp and Letter

If you have a Super Gameboy, SGB-01:

• The CPU number after "SGB-CPU"

• The Region manufactured, usually Japan

• The Timestamp, the last line on the CPU itself

If you have a gameboy pocket, MGB-01:

• CPU revision, printed on the back-center of the board by the manufacturing date

• Region manufactured, usually Japan

• Timestamp at the bottom of the CPU itself
