    I think its great! I'd like to know also!

    Yes.  It is possible to write to the mouse port.  (At least, one
    of my manuals mentions it)  There is a register you have to use.
    I'll try to find it in my hardware manual tonight.

Digi-View does it when it checks to see if there is a Digi-Droid out there and 
when it sends a pulse to the Digi-Droid servo to tell it to rotate.

    Hah!  So it's in the HARDWARE manual!  Is the Addison-Wesley
    A1000-oriented manual good enough for this, or do I have to spring
    for the A500/A2000 manual?

    - Cliff

A500/2000  manual?   Have the RKM and Intuituion/Hardware manuals been
updated?

    There's an A500/A2000 hardware manual that you can order directly
    from Commodore for about $40.  People have mentioned it elsewhere in
    this notesfile.  The jist of the comments was that it was overpriced
    for what you get, particularly if you already have the A-W hardware
    manual. 

    - Cliff

    Whoa... There's the A-W Hardware Manual, which really ought to be
    titled Hardware Programmer's Manual, and deals with low-level
    programming of the hardware.  It's currently out of print and being
    updated, so a copy may be hard to find in your bookstore.  The A-W
    manual is really about 90% software oriented.
    
    There is also an A500/A2000 Hardware Technical Manual, or some such
    name, which you can get direct from Commodore.  (There's a similar
    one for the A1000.)  This contains schematics and guidelines for
    interfacing peripheral hardware.  If you want to find out how
    autoconfigure works, here's the place.  The Commodore manual is
    about 90% hardware oriented, real gates and nanoseconds stuff.
    
    Sounds like the writer of the base note wants the Addison-Wesley
    manual. 
    
    P.S. If you think $40 is overpriced for the Commodore manual, look
    at the price of service manuals or schematic sets for any PeeCee.

    Can someone tell me where to order the Hardware Technical Manual?
    The one for the 1000.  I'm trying to figure out how to interface
    some memory with my bus.  Also, does it include Autoconfig
    documentation, or do I have to get that separately?

    Here is part of an old Usenet posting from CATS.  Note that 1.3-related
    stuff and the latest Developers' Conference notes have not been
    released yet to my knowledge.  The IFF disk is the latest version
    of all IFF specs and formats, and has been updated since this posting.
    (An older version is on Fred Fish disk 46 (??)).
    
    To answer the previous reply, both the A1000 and A500/2000 manuals
    contain descriptions of Autoconfigure, expansion bus timing, etc.
    The A500/2000 manual is much better written overall.

    TITLE:  Support Materials Available From Commodore      Sept. 1, 1987 
 
    The following is a current list of developer support materials
    available directly from Commodore Amiga Technical Support. The prices
    are for orders within the U.S.. Canadians should add $2.50 shipping
    costs per item.  For foreign orders, add $5.00 shipping costs per item.
    All prices are in U.S. dollars. 
 
 
        To order any of these items, send a check or money order made 
     out to Commodore Business Machines, to: 
 
           CATS - ORDERS                <----- (Department) 
           Software Administration      <=\

        Be sure to include your name and address, and the name(s) of 
     the item(s) you are ordering.  If you are a registered developer, 
     place your developer number on your check and envelope front 
     for faster service.  Delivery may take 4-6 weeks but is generally 
     much quicker.

    OK.  Here's the scoop on writing to the Game ports.  There is a
    register (on the 8520, I believe) called POTGO that controls all
    I/O activity for Potentiometer-type joysticks.  This seems to adapt
    itself well to reading and writing.  As stated in the hardware manual,
    there are a total of 4 pins between the two ports that can be written
    to.  (Pin 9 and 5).  Unfortunately, there is no direct support for
    this hardware.  The registers would have to be manipulated directly
    for this to work.  I believe the correct registers are POTGOW and
    POTGOR or something like that.  I can get the exact addresses if
    you are still interested after seeing this information.  You have
    to set the enable bits and write values, and then you have to tell
    it to start.  There are a lot of timing problems that seem to be
    involved, but I've never really tried this, so I can't be sure.
    The manual I found this in is the HARDWARE REFERENCE MANUAL.  This
    would probably be easiest to do in assembly language, but it is
    possible in C.

    Thanks for the info!  I think I'll try to track down a hardware 
    manual.

    I still have my PowerPad.  I got it and a couple application when
    Toys'R Us decided to dump them (Atari version).  I have buried
    somewhere around the house info on the protocol it speaks (a copy
    of the docs from the C64 PowerPad programmers kit, never found the
    Atari version, not sure they ever made one)
    
    The main problem with the PowerPad is the resolution.  It has, I
    believe, 120x120 points it can sense.  But it can sense them
    simultaneously.  Makes it great for finger painting, but not so
    hot for detail work.
    
    I'll hunt for the docs.
