On the right is the volume control and serial link port. On the left is the contrast adjuster and input for external power (6 Volts). There is not a very loud but not a wheezing speaker. Sound console produces stereo mode and very good quality.

And here lies another one of the success factors for Game Boy. If you look closely at the hole, the company logo is also visible on the board.īelow is a standard 3.5mm headphone jack. A little higher is information about the manufacturer. Their charge is enough for 10-15 hours of play. The battery cover in which 4xAA batteries are hidden. There is nothing particularly interesting behind. Such a scheme allowed us to get rid of a separate charge control chip. GB stops working approximately when it is almost off. The dimmer the light, the lower the battery charge.

The latter is arranged in the opinion of the current layman a little unusual. And so, on the front panel we have: a cross, 4 buttons, a screen and a charge indicator. Well, now, so as not to torment you for a long time, let's start a small external review, and then disassemble the device. Width 8 bits Screen size 160x144 (4 gradations) Let's start with the technical specifications.īus width 8 bits Address bus width 16 bits If you are interested in what the internal structure of the Game Boy Original is, you have a direct road under cat. On the Game Boy board, you can count exactly 4 microcircuits and practically no more surface mount elements. The device was based on a simplified and modified Zilog Z80 processor, there were 2 64Kbit memory modules and. And the simplicity in it was not only for users, but also for developers.

So I replaced the CPU (from an untested gameboy). At this moment I believed there's something wrong with the CPU. The original left channel still has the same problem.Ħ.

I swapped channels before going inside the amp just to make sure the amp is working. But if I cut the Right channel, the Left channel has only noise (no longer the gameboy logo sound followed by noise).ĥ. If I remove C4 (cutting the LEFT channel), the right channel is still working fine. I even swapped them between channel and no difference.Ĥ. I checked the 2 caps and 2 resistors on the CPU sound output. I checked the volume pot, I even bypass it with wires. I even swapped channels to make sure the board is working.Ģ. I made sure the small sound board is working. I've attached a schematic for the sound I found online.ġ. The same happens for the internal speaker and also for the headphones. On the LEFT channel i can only hear very faded the gameboy logo and after that the Left channel outputs some noise, and the noise has the right volume.
