Re: ZX Spectrum Next Keyboard

can't see why someone couldn't make an 'expansion box' that sits on the edge connector that outputs USB HID for keyboards to connect any keypress on the Next to a PC as a keyboard input! http://www.users.globalnet.co.uk/~jg27paw4/yr01/yr01_58.htm someone back in '84 did 1/2 the work for you, now jus...

id imagine you'd need to re-compile the code for the BCM2836, BCM2837 processors used in the later pi's

(I tried a pi 3, it doesn't work!)

Re: Since V0.8B: No startup after power on

what's your power supply like?, may sound an odd question, but most overall anything PCB realated for any project things like this tend to be power supply related... yes, it may have worked before, yes, it may have never had an issue before the firmware, but you'd be amazed at how often a change of ...

Re: RTC Issue

Hi Tim, some news about the RTC Issue: Some days ago there was a retro meeting up here where at least half a dozen ZX Next boards where on. (What I ask myself: Has this been the highest concentration of "Just The Board's" out in the wild ?! :D ) At least three boards have had issues with the RTC. W...

Re: Vin input capacitor

slight disturbances (mainly drops) have a huge impact downstream on the circuitry if Vin Drops too much, too quickly, the reg can't perform its function properly, so gives out a pretty crappy voltage (or none at all) Cin Capacitor is a reservoir of 'voltage' that smooths out ripples / dips in input ...
