Emulators for 8080/8085, 8086/8088, Z80, 6502 and TMS1000-family CPUs

8086 / 80286 PC compatible computer board with FPGA

Run (more like walk) 286 real mode C programs on an XT

FreeDOS Network Package Manager 16 bit

This repository contains wmake style makefiles and patches to build Lua on Open Watcom 1.9 or later. This allows Lua to be cross-compiled for several legacy Operating Systems as far back as 16-bit DOS.

Microsoft's published himem.sys version 2.06 from XMS20.ARC

An educational segmented kernel (286 like kernel).

80286 BIOS source code

A small program which lives in boot sector of your storage and shows a small image when you boot it

Windows 2.0 DDK

Very simple UTF-8 to codepage 1250 definition packed into DLL.

Some of my old source code from 1990s (evidently a prior attempt to initially write Dave Gnukem in 80286 assembly language in 1994, 16-bit EGA - sometime in 1995 I more sensibly started again in C++). Uploading on the off chance someone finds this useful.

DOS Assembly Programs and Utilities

Very simple test 16-bit dynamic linked library.

Just a simple repo containing some of my old (and ugly) Watcom projects from 2019.

Very simple testing program for test 16-bit DLL from another repo.
