ZX Nuvo 48 Help

Post by mabby »

Hi everyone - I am trying to get back into the spectrum scene & during that late night ebay thing we have - I bought a part completed ZX Nuvo 48!! - Can anyone help me complete the project - Most of the components are on the board (The U57 smd needs to be surface mounted correctly, but I am sure I can do that) But I do not have any documentation as to what's missing (The Ay sound chip & Z80 I am assuming can come from a donor spectrum that I have) bust again I am not sure what else I need, like the am29f040/HM628128/28c64 chips that are missing - ANY help would be greatfully received

Step up to red alert. Sir, are you absolutely sure? It does mean changing the bulb :!:

Hi,

Are able to solder missing components? Do you have any experience with reading circuit diagrams? Do you have basic tools like a multimeter?

If you need any documentation you can contact @superfo, and he is registered on this forum. Don designed this board and he will be able to give you a hand.

Cheers,
Claudius

You can get document from here.

To make it works you need to program U2, U5, U59 which require programmers.
