We include this in the FreeDOS distribution, so you can just use that. You'll need a '386 or better to compile, but this will generate 16-bit programs that should run anywhere. > Can I code on my Windows 10 machine or should I do it on the legacy box. > I'd recommend setting up a PC emulator (or "virtual machine") on your Windows system, and boot FreeDOS in that. That's what I do (I run Linux, but it's the same). Many folks use VirtualBox. Be aware that if you're running VirtualBox to boot FreeDOS 1.2, you'll get "invalid opcode" errors - there's a fix provided at https://www.freedos.org/download/ > Where can I find legacy software for EMR (electronic medical records) like > CHIRON (see below) > > I don't know, sorry.
