Just a thought, maybe if you use WINE on a Unix-like system it might work? WINE isn't a full emulator, rather an API implementation though so you may run across similar problems. COBOL is a language I'd very much like to learn, the Latin of computers. Nothing of use to me with the exception of curiosity of the code. The GNU-COBOL compiler had no problems compiling these 30 year old apps, written on a DOS machine by a friend's mother for deployment on mainframes that probably filled rooms. Most of the time I find it easier to use Arch GNU/Linux, I get complete control over my system and in addition to the freedom there's usually also source code available for my apps: Case in point, I found on some old floppies programs written in an old dialect of COBOL. Believe it or not, a lot of servers are running outdated 32 bit versions to maintain compatibility with legacy 16bit apps, for which if there is no source code cannot be easily ported to 32/64 bit.Įven some purely 32 bit programs I've come across are wrapped in a 16 bit installer, rendering them needlessly useless on contemporary systems! I personally have largely jumped the Windows ship, but keep a copy of Windows 10 to play some games I bought for Windows. There was an article in The Register recently aimed at sysadmins (I'm having trouble finding it but will post it if I do) using Windows on whether they should make the jump to a 64 bit version of Windows. The only solution would be to run in a 32 bit OS (which maintains full compatibility with the 16bit instruction set as the CPU operates in 32 bit mode) or to emulate a 16bit or 32 bit Intel architecture processor. Hence, no DOS or Windows 3.x programs will run and some earlier 32bit Windows programs will also not work as they call some 16 bit libraries, even if the app itself is 32 bit. If a 64 bit operating system is installed, the CPU operates in 64bit mode and support for certain 16bit instructions is deprecated. Put simply, these processors operate in one of two modes, depending on the operating system. The reason 64 bit has issues with old games is to do, as far as I know with the amd64 (x86_64) processor architecture.
