Re: Keyboard not always recognized.

I had a spare official Raspberry Pi power supply that is rated at 5.1v 2.5amp and now all my PS/2 keyboards without an issue.
Also I'm using a heavier, shorter Mini USB Cable.

Screen shakes when saving to Pluggy McPlugFace.

Hi,

Just another question.
When I save a program written in basic to Pluggy McPlugFace the screen image shakes up and down.
Is this normal, I haven't seen another one do it on youtube.
Does this happen to you ?

Thanks

Re: Keyboard not always recognized.

I found an old IBM keyboard that doesn't have the problem.
It works every time I turn on the Gigatron.
It seams there might be some compatibility problems with later keyboards.
Some work better than others.

Keyboard not always recognized.

Hi, 50% of the time when I power up my Gigatron it wont recognize the keyboard and I have to unplug and plug back in a couple of times. I have tried different PS/2 keyboards but they all do the same thing. Is this the Pluggy McPlugface adapter ?, for example firmware on the PIC ? Is anyone else havi...

Re: Changing default screen mode.

Hi,

Thanks for the info.

I am new and just want to change a couple of values using a HEX editor.
I have no programming experience and just want an easy option.
For example the Line (Address) number and the HEX values.

Thanks for helping :)
