RC2014It has taken me almost 5 years to start assembling this kit. But at least I have started...
haitchfiveThe XBerry-Pi doesn't look like a ZX Spectrum at all, but it's the new ZX Spectrum Next-compatible creation by Don Superfo. If it does anything analogous to what the Superfo Harlequin 128 did, it's going to be amazing. Hopefully the strange branding decision won't detract from it.

I'm hoping the 74hc32s and74hc257s are on their way. I have the other chips but am keeping them safe for now.
Still missing one Zener diode and two capacitors. Also need to fit the keyboard connectors but we're nearly there.

I've added a link wire round the back, the solo red wire, because the VCC impedance from regulator to here was a bit high for my liking. The other two wires are so I can power with a current and voltage controlled power supply for short testing.

Crystal Y2 had to be laid flat to fit an original speccy case, there's enough room in the original case for a huge non-polar 220uF at C28, chosen because it's for the video signal. The transistors in Q6 - Q13 are hard to source, I have functional and pin equivalents but these are special, thin form factor transistors, a shame there's plenty of room to use a more common part.
