They may be read from the keyboard controller with a command 0xDD.

Surprisingly, Sun's website still (as of Oct-31-2001) has the JavaStation press release online at http://www.sun.com/961029/JES/ http://www.sun.com/961029/JES Many thanks to Gary <firstname.lastname@example.org> for pointing this out.
Surprisingly, Sun's JavaOS 1.0 environment for the JavaStations is still mirrored about on the Internet even today (Oct-31-2001). JDSE 1.0.1 can be found at: http://sunsite.tut.fi/javastation Many thanks to Gary <email@example.com> for pointing this out.
Download the link labeled 'jdse.tar'. JDSE 1.0.1 was one of the first demo version of JavaOS available, and was a free download. Later, downloads were restricted to paying customers. This first version is merely a boot image of JavaOS and the HotJava browser. No telnet or ssh applet, no X Windows applet, no file manager, no email applet, nothing but the browser. Starting to feel boxed in? Welcome to the official software of the JavaStation.
Copies of latter versions of JavaOS as included in the NetraJ software bundle have not been located online yet. This is probably due to the latter versions, namely NetraJ 2 and above, was retail software, and never available for free download from Sun's site.
Pete Zaitcev has written a document describing how to enable IDE on your Espresso model JavaStation. It is included here with Pete's permission.
By Pete Zaitcev 1999/11/01 2000/08/22 I am not responsible for any direct or indirect damages to your equiment or yourself resulting from you reading this document. USE THIS INFORMATION ON YOUR OWN RISK. IDE interrupt line is connected "upside down" on the Espresso. To have IDE working we need to insert an invertor in it. We borrow the invertor from ISA IRQ3. If you want to use ISA modem, set it to use COM3/IRQ4 (please realize that Linux IRQ level would be programmed in CPU PCIC). The following picture provides an overhead view: +==================== wire 1 =======================+ # # # 1202 1200 # 1201 # +-------+ +-------+ # +-------+ # -! REP !--14 1 -!

Disconnect 1202 5 & 6. Not knowing if I need them I lifted pins with a model knife. You may just cut them with side cutters. 2. Lift pins 1200 10 & 11 but do not cut them! 3. Run wires from resistor pads "A" to pin 1200 11 and from pad "B" to pin 1200 10. Resistor pads are much easier targets for soldering at home than pads under pins 1202 5 & 6. I am a software engineer, so I did it the easy way. I did not bother to glue wires as a decent electronics hacker would do. You are all set. Get kernel 2.4, hack drivers/block/Config.in and enjoy! P.S. Let me know if you have drawings of hard drive brackets for Espresso.
When booting your JavaStation, there are certain key combinations you can press to enable some boot monitoring functionality.
Javastation Key Combinations These are the key combinations that allow you to perform the command monitor functions: Press left Alt, left Ctrl key, letter; then turn the power on. You have to have the keys pressed when you turn on the power otherwise it will not work. Ctrl-Alt-H Help on chords Ctrl-Alt-B Show progress banner Ctrl-Alt-W Show Ether net address and memory size Ctrl-Alt-D Run diagnostics
These key combinations do not work with the Mr. Coffee model.
