Ok, thats seems to be the job of the SN74LS139AN chip.



So I guess I should figure out what is connected to 2G, 2A and 2B of the SN74LS139AN.
So if I want to solder a DSP1 into the Neo Myth I would also need to solder the SN74LS139AN and the SN74HCU04N in it.

Still wondering what the M 7600A 271 thing is though.

Never mind, there is simply not enough room inside the Neo SNES Myth for three chips plus wiring.   ~sm-62.gif~.gif ~sm-62.gif~.gif
So I would say that it is impossible to fit a DSP1 into the Neo SNES Myth. The only solution would be a redesign of the Myth pcb so that the DSP-1 can be soldered in like the cic. If you need a tester for the new pcb design, I know one  ~sm-79.gif~.gif

Now I will send ronaldo his cart back ... well first I have to finish Zelda A Link to the Past of course  :)
