Re: Bit stuck with my BitStik

Err, Martin, the ADC chip does not handle the fire button inputs...

That's done by the system VIA (6522) chip (IC3).

More likely to be poor connections on the plug/socket or dry solder joints on the PCB connections for the analogue connector though.

Re: Electron sound/audio output (SOUND O/P, ADOUT) connections

I was looking at the documentation for the Electron cartridges (AppNote 014) and was wondering whether cartridges might be able to send sound through the Electron's speaker. I suspect the answer is No. At least, not according to the way the audio circuit is connected as shown on the schematic of th...

Re: Model B buzz when pressing keys

All Beebs and Masters have some level of noise that comes from the loud speaker. The audio circuits are picking up some of the digital signals. So as the CPU does different things, you get a different noise.

This thread may help ;-)

Sounds interesting. I may want one (PCB only or board & parts). It would help if you can give more details ;-) And note that the length of the ribbon cable does affect the stability of the Beeb. So best to keep it as short as possible. I suggest having it come out the right hand side of the case...
