zasm accepts source code using 8080 and Z80 syntax and can convert 8080 syntax to Z80.
zasm supports various historically used syntax variants and the syntax emitted by sdcc.

zasm can generate binary files or Intel Hex or Motorola S19 files.
zasm can generate various specialized files for Sinclair and Jupiter Ace and .tzx tape files.
zasm can include the generated code and accumulated cpu cycles in the list output file.
zasm can run automated tests on the generated code.

zasm supports

• character set conversion, e.g. for the ZX80 and ZX81 and proper decoding of utf-8 in text literals.
• multiple code segments
• including and compiling of c source with sdcc.
• automatic label resolving from libraries
• automatic compression using ZX7
• well known illegal instructions
• multiple instructions per line using '\' separator

the source can start with a BOM and with a shebang '#!' in line 1.
the source (text literals) must either to be 7-bit clean or utf-8 encoded.

Run automated tests on the generated code.

There you can download Binaries for OSX and Linux and some older versions for other OSes
and there you find the Documentation and an online assembler.
