 cc65 - A fairly mature C compiler + toolchain for the 6502 family with lots of target
 platforms and an extensive library. The code generation is
 not great, using the AX register pair and a parameter stack for local variables that has to be
@@ -51,12 +53,27 @@ WLA-DX - Some other weird cross-assembler with lots of CPU targets.
 z88dk - A Small C-derived cross-compiler for the Z80, supporting 20 target
 machines.
 
-SWEET16 - Woz's tiny bytecode interpreter on the Apple ][ integer BASIC ROM.

+Java Grinder - Compile Java bytecode to microcontroller assembly.  Currently
+supporting MSP430, dsPIC, 6502/6510, 68000, MIPS, TMS9900, and Z80 with
+platforms that include Commodore 64, Sega Genesis, Atari 2600, Apple IIgs,
+ChipKit (PIC32), TI99, TI84 and more.

+ZX Basic - This cross-compiler is focused on ZX-Spectrum, but with some
+patchworking it can be used to compile to whatever machine running on z80
+architecture. (Python)
