This character set is based on the ZX Spectrum system font, but extended to cover the ASCII OEM character set. The original Spectrum font has a light airy feel, but there are a few awkward characters and some that are hard to distinguish (e.g. W and V). Some of its quirks (blocky X and period) are what give the typeface its character, so I've left those unchanged.
