De-macroisation negatively impacts speed, but this emulator doesn't need to be fast. Clear code is more important. |

8086 emulator
This folder contains emulator for 8086 binaries of Collapse OS. The bulk of it is a fork of Fake86 by Mike Chambers.
forth is an imaginary hardware used for userspace development and testing.
This machine has an imaginary interrupt API and does not conform to PC/AT.
pcat is a very simple PC/AT emulator. The BIOS interrupt hooks implemented in
it only cover Collapse OS' own needs.
Requirements
You need ncurses to build the forth executable. In debian-based distros,
it's libncurses5-dev.
Build
Run make and it builds the forth and pcat interpreters.
Usage
The ./forth executable here works like the one in /cvm, except that it runs
under an emulated 8086 machine instead of running natively. Refer to
/cvm/README.md for details.
pcat needs to be suppied a path to a floppy disk image with a proper MBR.
disk.bin provided by the pcat recipe is sufficient.
