Some of those looking for a method to run Alpha4 under newer 64 bit versions of windows (for example Windows 10) have tried using vDos. vDos is a DOS emulator designed to run business applications under the newest Windows Operating Systems. Originally vDos would not run many version of Alpha4 because it did not supply math co-processor emulation.

The author of vDos has released a new version of vDos 2017.08.01 that added a FPU (Floating-point unit) to the emulated CPU.

I have tested vDos version 2017.08.01 and it will run Alpha4 Version 6 to run under windows 7 64 bit quit well.

What a walk down memory lane.
