I have one from that era that could switch between 8086 and Z80 so it could run CPM80 as well.

Is it a NEC-V20 (or V30) machine?

Possibly. I don't remember. I know it wasn't Intel. I would have to dig through a lot of stuff to find the answer.

Well, just for the record, dosbox's Ctrl+F11/Ctrl+F12, are very handy:

And for Qemu there is Qemu brake:

Well, your just-for-the-record links are not just for the record, they are actually quite good

Happy you found those useful, and now, for no apparent reason:

Description

vDos derived from the DOSBox project (http://sourceforge.net/projects/dosbox/).

DOSBox is targeted at gaming and available for many operating systems.

If you consider using DOSBox for a database application in a multi-user setting, DON’T, you’ll mostly end up with corrupted data.

vDos is for serious (mainly text mode) DOS applications, Windows 32/64 bits (XP and later) only.

It lacks many of the hardware emulations of DOSBox (no joysticks, basic VGA...).

Instead it adds a live file system, file/record locking, Windows printing, a scalable screen font and more.

You should be able to run your DOS application quickly in a safe and convenient way.
