8086tiny-c128 is a port of Adrian Cable's 8086tiny to the Commodore 128. This is currently a work in progress and my code changes are still a disgusting mess. While the current version should work on native hardware, it is currently most useful in an emulator such as VICE in "warp" mode.
If your business needs (!!) require a faster x86 emulation solution on your 8 bit Commodore computer, consider the C64 port of y86.
- Real or emulated Commodore 128
- 4 MB Ram Expansion Unit or 4 MB of SuperCPU RAM or 4 MB geoRAM cartridge
- Hard drive or solid state drive with at least 2 MB of space (mostly for 1.44 MB floppy boot image)
- 80 column display
- A UNIX-like build environment with make
- llvm-mos SDK v22.5.0 or higher
- FreeDOS from 2012 boots and runs.
- Linux ELKS 0.9.1 boots and runs. The contents of the screen may be filled with VT100 escape sequences and may be difficult to interpret.
- Simple command line applications that only use text mode and don't make too many crazy demands on cursor positioning should be usable.
- real time clock
- many keys on the keyboard (e.g. CTRL-ALT-DELETE doesn't work)
- hard drive
- graphics modes
- characters such as underscores and curly braces
- speaker or other audio device
- 1571 and 1581 and FD2000/4000 MFM disk support
- mouse
- serial port
- parallel port
- ethernet
- lots of other things (welcome to open an issue if you don't believe it is mentioned)
Currently there are several Makefiles to target several platforms
- To build for a UNIX-like environment, just type
make - To build for a Commodore 64 with 4 MB REU, type
make -f Makefile.c64 - To build for a Commodore 64 with a SuperCPU and 4 MB of SuperCPU RAM, type
make -f Makefile.scpu64 - To build for a Commodore 64 with 4 MB geoRAM cartridge, type
make -f Makefile.c64georam - To build for a Commodore 128 with 4 MB REU, type
make -f Makefile.c128 - To build for a Commodore 128 with a SuperCPU128 and 4 MB of SuperCPU RAM, type
make -f Makefile.scpu128
For UNIX-like environments, just type ./runme as in the original version of 8086tiny.
For the C64/128, first type LOAD"LOADRAM",8 followed by RUN to load the bios (bios) and boot disk
image (fd.img) into RAM. To start the emulator, type LOAD"8086TINY",8 followed by RUN.
