Re: 2 key rollover on an Atom?

Hi STH-ers Opinions, please.. is there a way to implement key rollover on an Atom, preferably without resorting to hardware hackery? Cheers JonB (In case you haven't heard of the term, it's when you press a key, hold it down and press another. This tends to happen when typing quickly, but the Atom ...

Does anybody need some eproms or ram chips? Or perhaps Atom Lisp, Chess or a printed circuit board without components?
I'd be interested in the empty PCB ! Which issue is it by the way,

Re: New Atom boards....

Would you mind posting the PCB schematic as well as the VHDL - just so I can try and work out how all this stuff works ?

I had a quick look as the schematic, and I think this could be done in the Xilinx, and would not require any PCB changes. Is the source for the Xilinx available for end user hackery? :D I'll post it tonight, the latest versiion will be on the machine in the back room that I use for programming the ...

Thanks, Phil! Mine freezes upon heating. :( Do you have a can of freezer spray ? Maybe try opening the case, putting the 'top' half upside down on some blocks or books so the keyboard isn't being pressed all the time but you can get to at least BREAK and SPACE, wait for it to lock up and then start...

Faulty Atom Now Fixed

Hi, I've finally got my Atom working - previously it was mostly freezing after correctly displaying the start-up screen, no response to the keyboard. Occasionally it would taunt me by working correctly. After reviewing various people's suggestions, rereading danielj's post here: http://www.stardot.o...

Ok thx for that. Looking on the schem of the external Co-Pro, I can see that link that selects the power to the ULA, but it doesn't seem to be present on the internal one, so that would make sense. I've not found a schem for the ADC06, no. Thx, Mark. I think the internal co-pro might be significant...
