Resurrecting this thread...
If Vega is too expensive or limited for you, there is another rival: the ZX Uno (I guess I did mention it here).
ZX Uno is aimed to clone all the hardware of ZX Spectrum in a raspberry pi sized board. Their features include:
- PS/2 keyboard input.
- RCA and RGB (SCART) video output.
- Audio input and output, to allow you to load games using the traditional way.
- Atari joystick input, to use old joysticks.
- SD card to load games instantly (it is DivMMC compatible).
Also, this is not exactly a clone of ZX Spectrum... although the first project was to clone a ZX Spectrum, this board can different computers. They're working into other cores (SAM Coupé, Jupiter Ace, Sega Master System...).
You can see all the information on their web. On that page, you can download the schematics, boards and software for this thing.
Today, they've launched a crowdfunding campaign on spanish site Verkami. You can pledge for mounted boards with and without case (remember, you can adapt a standard Raspberry Pi case). On this campaign there are not ZX Uno kits... so nobody will need to solder anything.
P.S.: If anyone living outside Spain want to back the crowdfunding, remember to include the "international shipping"reward.
I have traveled across the universe and through the years to find Her.
Sometimes going all the way is just a start...
I'm selling some stuff!
