Off ebay, An Amstrad CPC 6128 will do.

Though you may want an SD Card adapter to get the files onto it.

As the banner on the site mentions, it works on Amstrad CPC, MSX, Amstrad PCW and Enterprise 64/128 (I'm not sure what this last one is).

The Enterprise was a British dream 80s computer that most people could not afford.

For me this started the trend of the render being much nicer than the final product.
