MUS-2020 Prototype - Creative Game Blaster Clone
This is Gameblaster Clone derived from MUS-1099 Design.
Anyone who knows the MUS-1099 knows what problems it has.
In particular its amplifier has an immense power and there is a lot of background noise.
The MUS2020 design lacks the finishing touches, but is promising.
My first test was to build the part with SMD components and to change the noise level, which was successful.
Unfortunately the PCB has a few careless mistakes.
-> PCB is too thin (0.2mm) (In the XT the slots are relatively wide, I just tinned the ISA contacts of the card .., it's just HASL anyway)
-> PCB is too short
-> Conductor tracks could be thicker
The missing capacitors in the picture are filters 😉
As promised, the first audio recordings:
