-
- :What_is_this?
-
- This is a simple, DOS-based, hypertext document
- that serves as an intermediate-level tutorial
- on logic design using the EPX780 FPGA as a
- prototyping device.
-
-
- :How_do_I_use_this?
-
- Basically, you use the cursor control keys, PgUp
- and PgDn keys, or the mouse and scroll bars to move
- through the text. If you see a word you don't
- understand, put the text cursor on it and hit the
- ENTER key OR click on it with your mouse cursor and
- you will transfer to the place in the text where
- the term is explained. You can return to where you
- were by hitting the BACKSPACE key.
-
- The words or phrases ~highlighted like this~ are the
- best candidates for getting further information,
- but you can try clicking on anything you see. If
- you click on something like ~<epxbrd.pcx>~, then a
- viewer for the PCX picture will take over the entire
- screen. To return to the hypertext document, just
- click the mouse or hit any key on the keyboard
- (except for the ENTER key).
-
- Some explanatory text will appear in separate
- windows. You can drag these windows around and
- resize them with the mouse.
-
- Other than that, you can try anything you see in
- the menus and see what happens!
-
-

- :Where_do_I_find_these_documents?
-
- These documents will be kept on the FTP server
- `~ftp.vnet.net~` under the directory `~pub/xess/hyperdoc~`.
- You can login to this machine as `~anonymous~` to
- retrieve the documents. Each document will be
- stored as a self-extracting archive. Merely download
- it into an empty directory on a DOS PC and execute
- it and the document will install itself. Then type
- ~`GO`~ to view the document.
-
-
- :Please_keep_me_informed!
-
- If you would like to be informed when new documents
- are released on the Internet, just send a message
- with the subject line of `~hypertext~` to `~devb@vnet.net~`
- and we will add you to our subscription list.
