I have the C source. I've written the display drivers. I either need
someone to convert the source to work under Z88DK and the odd memory
map of the Spectrum SE, or someone to explain the C source to me so I
can reimplement it in Z80 code. For anyone who hasn't heard of the
Spectrum SE it's essentially a 272K Speccy with an 8x1 attribute screen
mode (that is used by this conversion) emulated by FUSE on Unix/Mac and
EightyOne on Windows. Drop me an email if you're interested.
