Each one of these sections includes a bunch of illustrations and screen shots so they may download a bit slowly on slow connections.

Section 4 - Downloading a file


1.

Select "List of Files"

When you click on Load... the load screen pops up. The load screen allows you to download either:
Floppy Image FileSelect this option if you want to download a complete floppy image. Floppy image files have names with extensions that vary from vintage machine to machine. Some of them are named file.dsk for example. For more information on this option, please see the example Section 2 - Selecting & downloading a floppy image .
List of FilesSelect this option if you want to download one or more individual files. The SVD-CP will wrap the file(s) in a floppy image before downloading them to the SVD. This is a great option if you have a binary program, text file, or even basic program that you would like to run.
For this case, select List of files.

The SVD-CP is capable of downloading a single file (or group of files if you like) to the SVD without having a floppy image containing the file. The SVD-CP comes with multiple floppy images that can be used as "containers" for these files.


2.

Selecting a floppy image "container"

To use this feature, you first need to select the desired floppy container image. This images appear in a selection box at the bottom of the load screen (as in the picture to the right) labeled as Operating System. The point here is that each image contains an "operating system" or at least a "file system" image that the SVD-CP knows about. By knowing the file system, the SVD-CP can write an individual file on it. In fact, it can write many if there is enough room.

Note that there are often many choices of operating systems and, therefore, file systems to choose from. Most of these images are also bootable. In fact you can use these images without adding files. This turns out to be a very nice way to download a bootable file system image.

Some files (like binary files or even Basic programs) require a particular operating system or Basic version to operate properly. If you find that one of these programs will not run after download, try a different "container" floppy image with a different OS or Basic.


3.

Selecting files

Once you have chosen the container image to use, you must simply select the files you would like to include in the image. Click on the Add... button to browse for a file. Continue to click on Add... to add multiple files.

To delete a file from the list, highlight the file and click on Delete.

For some Operating System selections the Add... button is greyed out -- i.e. it won't let you click on it. In these cases, the SVD-CP doesn't understand the file system on the given image, so it cannot add files. HOWEVER, these images can still be used to boot your machine. You just can't add files to them.

Remember: you do NOT have to add files to an image to use it. If you select List of files but don't select any files, the given Operating System image will be used even though additional files are not added to it. This is a great way to boot up an operating system...even if you don't have a separate image.

After you have added all of the files to image (if any) click on OK


4.

Download All

In this example, virtual floppy #0 was loaded with two Zork CP/M files. In the area where the image name normally appears, under the picture of the floppy drive, the words "(mixed files)" appear. This indicates that there are a set of files loaded in that virtual floppy.

At this point, as when loading a simple image you need to click on Download All to download the virtual floppy to the SVD.


5.

The SVD is now ready!

Before download, and during the download itself, the SVD will not respond to floppy requests from your vintage computer. It will essentially be "invisible."

After a completed download the the SVD, however, it immediately begins to operate as a floppy drive to the vintage equipment. That is, any request by the vintage computer to a floppy drive that matches a loaded virtual floppy will be serviced by the SVD. This works for both booting, and reading data from the SVD. In most cases, this includes writing to the SVD as well.
