Re: How easy from Next computer to board DYI?

ok, the schematics are up on Gitlab.... it's actually fairly easy to DIY a Next as there really isn't that many components on the board... Fire up EasyEDA There's already suitable FPGA libraries there Copy the Schematic over to EasyEDA create a PCB (suggest to go straight to an expensive 6 layer to ...

Re: Measurement Request for those already with a Next

There's at least 2.5mm 'free' underneath the Next PCB..

The Joystick DB9 locating lugs stick out underneath that far!

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...

Re: Correctly setting up the Accelerator Board - Pi Zero W

Code is for the BCM2835 processor used in the Pi 1, zero, A, CM1

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!)

(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...
