Assemblers
Any Z80 assembler can produce code suitable for the Next. However, the Next and most emulators cannot load raw blocks of Z80 code, so a Spectrum specific tool will be useful for creating .TZX or .TAP files with the necessary loaders.
- Provides a complete Z80 IDE and Macro assembler, plus an integrated Spectrum emulator
- The emulator does not support all features of the next
- A long established Z80 assembler, but has been out of development for a long time
- Supports all currently known Next extension opcodes through this modified Pasmo from Russ McNulty and Tony Thompson and also now supports outputting .sna files to use with CSpect, thanks to Russ McNulty
- SNasm - included with the CSpect emulator
- Supports the Next extension opcodes directly
- z80asm - part of Z88dk
- Supports the Next extension opcodes directly, linking assembler with large z80 library, targets any memory configuration
Compilers
- sccz80 and zsdcc - part of Z88dk
- "sccz80" is a small c derived c compiler that is nearly c90 compliant with a few notable exceptions. Emphasis is on small code.
- "zsdcc" is a fork of sdcc-z80 that is an open source optimizing c compiler with c90 and elements of c99 and c11 compliance.
- A Next target is present and under development. Output file types include tap, sna, and esxdos dot commands.
- A Basic to Z80 compiler with extensions added to Sinclair Basic.
