Hi Timo,

Thanks   A good opportunity to run 16-bit applications on 64-bit operating systems.

This is cute indeed

Attached two "projects". Open in RichMasm, hit F6. Works like a charm on Win7-64

Where fpu instructions are?

Sorry, they are in the Hello16.asc file (which opens with \Masm32\MasmBasic\RichMasm.exe); the old *.asm crept in by accident. Building requires the attached DosBasic, which is a simplified 16-bit version of MasmBasic.

Apparently hello16.exe work perfect in win32

If you have a 32-bit version of Windows, yes indeed. On my Win7-64 box, I see only an ugly message from the OS. Except if launched as msdos\binary\i486_x64\msdos.exe Hello16.exe - then it works.

Having spent too many years long ago in MS-DOS with 16 bit real mode apps, if you want the real thing[tm] fish out your MS-DOS 5.0 disks and set up something to install them on or in something like a DOS emulator if you don't have a spare old box to do it properly and see how long it takes you to get tired of working in a 16 bit real mode interface.

It works, but lacks some features of DosBox. Of course, installing MS-DOS in a virtual machine is more solid.

Bottom line: Still waiting to see some software from China or Japan I would like to use.
