Zoomer DOS Config & Commands
Here's a list of the commands available for the Zoomer. Please note that
Datalight provided the ROM-DOS v3.31 which is included in the Zoomer.
For users that are used to using MS-DOS, ROM-DOS is nearly identical. Keep
in mind that only commands for v3.3 are supported on the Zoomer.
Thanks to the support of Datalight the following information is available.
Let me know if you find any additional commands that are not documented.
