The name of the Z88 emulator is constructed by two parts, "OZ" - which is the name of the Z88 operating system (see the name in the top-right corner of the Z88 screen), and "vm" - which is short for virtual machine. The main focus of this emulator is to be able to develop software for the Z88, on the Z88. The screenshot below displays a running Z88, booted with the operating system on an external card, in slot 1. Every Z88 has a built-in operating system, supplied in slot 0 using a 128K ROM/EPROM. In OZvm, typically the slot 0 ROM is using a 512K Flash chip emulation running latest OZ release (illustrated by the "128K 512K FLASH").
History
Before OZvm, testing software code had to be done on the Z88. This was a two stage operation.
...
This method, although quite novel, was very time consuming. What was needed was a Z88 emulator on the same desktop as the software development was being writen written on. Having both operations at the same place, would be a more efficient and quick way to test and transfer the code. .
Install & run the emulator
From the beginning, it was the intention that the emulator would be able to run on multiple desktop platforms without too much effort on our part. We chose to use the Java platform. Today, we have used Excelsior's JET compiler technology to native compile the application for Windows, Linux and Mac, giving fast and smooth emulation.

An example of using the emulator
Here's a screen-recording done on Linux, illustrating how the emulator typically can be used:; inserting a card with an operating system or application, running & debugging it.
