Those variations were failing to truncate the result when +a 16-bit operand size was in effect, and if the destination was a register, the upper 16 bits of that register +could become corrupted. + +The [Windows 95 Test Machine](/devices/pc/machine/compaq/deskpro386/vga/4096kb/) hard disk has been updated +with a complete set of Windows 95 files from a "Compact" installation, and first boot has finished, so instead +of the initial "Getting ready to run Windows 95 for the first time..." splash screen, you'll see the normal +Windows 95 startup screen. + +The machine is still a bit finicky. It easily gets confused about the state of its shift keys if you switch away +from the browser and then back again.
