Bibliography

List of information sources used for material on this Wiki.

• The SpecNext site gives some hardware information, but not on all topics, and currently, that information is not updated as good as the wiki pages here. As an example, its list of Next registers reflects the 2.00.27 core, whereas this wiki covers the newer versions, using as the reference the files maintained by the firmware and core developers: nextreg.txt and ports.txt.

• Data on standard Z80 opcodes is from the Z80 documentation. The undocumented opcode information is largely from here.

• The CSpect emulator's readme files are a first release source of information about the extended Z80 opcodes and some additional details on memory organization.

• The Sinclair FAQ Reference section hosted at World of Spectrum provided most of the technical data on the legacy machines.

• Jonathan Cauldwell's guide How To Write Spectrum Games gives valuable information on implementation on the base machines.
