TRACKPOINT II:
   The ThinkPad 720 and 720C provides a unique cursor-pointing device called TrackPoint II, which is built into the keyboard.  It works like the mouse and allows the user to point and select icons on the screen under control of the application.  It consists of a device that stands between the "G" and "H" keys, accompanied by two "Click-Buttons", which are positioned below the space-bar.  The device reacts to pressure from the finger-tip and the left button is used for selecting or dragging items on the screen. The right button simulates the Enter key in some applications.

DISPLAY (MONOCHROME): 
   A 9.5-inch diagonal LCD, Supertwisted Neumatic (STN) 640 x 480 pels, Video Graphics Array (VGA) resolution, cold florescent sidelighted display with an 18 to 1 contrast ratio. Depending on the application, up to 64 grey scales can be addressed. It displays black characters on a white background and it may be reversed to a white on black mode by a simple switch operation.

DISPLAY (COLOR):
   A 10.4-inch diagonal color LCD, thin film transistor (TFT) 640 x 480 pels, Video Graphics Array (VGA) resolution, cold fluorescent sidelighted display with a 100 to 1
(minimum) contrast ratio.  Depending on the  application, 256 colors are available simultaneously out of a palette of 4,096 colors in VGA mode (640 x 480).  There are over 921,000 thin film transistors used in its construction, and with advanced manufacturing techniques a defect rate of less than .00002 can be maintained.  This quality state of the art VGA screen provides clear, bright, vibrant colors approaching cathode-ray-tube technology.

The external input device port can have the following devices connected:
-   IBM PS/2 Miniature Mouse (#5443, 07G0033)
-   IBM PS/2 Numeric Keypad (#5445, 07G0032)
-   IBM PS/2 Keyboard/Mouse Connector (#3145, 54G0441).
           The IBM PS/2 Keyboard/Mouse Connector is required when:
    -   Attaching an external keyboard
    -   Attaching an external keyboard and mouse.



9552 IDE Controller Kit

Compatible with TP 700/C, 720/C, replaces existing cable. 
Supports 32-bit access in W95 (all others use 'compatibility mode'). 
Uses any 8-12mm IDE drive >/=540MB; BIOS rounds down to 2GB,1GB or 540MB. 
Requires new BIOS chip, refdisk ver 1.20. 
About 2x as fast as original ESDI drives.
 

   These interfaces were designed by the Swedish company Onsite in about 1995.  There seems to be some interest in these, and there are about 500 unpopulated flex PCB's left, so they may put back into production (the remaining 500 only) at some point. These were used in replacement plug-in drives sold to corporate customers (@$1200+ in 1995!).
   These kits can be used in the 700, 700c, 720, or 720c. However, this requires a upgrade BIOS 

   The strange 'round-down' scenario is a function of the controller chip passing specific hard-coded geometry parameters to the bios. It was easier to modify the bios than re-do the chip as drive sizes increased. They all use the same cyl/sector count, but the head no. is 16, 32 or 64 for the 540MB, 1GB and 2GB sizes respectively. IBM never made any MicroChannel drives (Ed. ESDI?)  bigger than 160MB, and their 240 and 340 drives used a similar interface translation chip.



SECURITY BASE:
   It is designed to prevent unauthorized operation of the computer in the following ways:
o   Bolts down the system on the desk
o   Keylocks system in the security base with the hard disk locking mechanism (padlock optional)
o   Prevents removal of hard disk
o   Prevents removal of IC DRAM cards and coprocessor
o   Prevents access to the screw holes in the system
o   Prevents access to the system expansion and I/O connectors.

SECURITY UTILITY DISKETTE: 
   The user can set a privileged access password to the system to limit the use of the system program.  Once the password is set, the boot drive selection and/or an I/O port usage can be protected from tampering by any of the reference diskettes.

IBM THINKPAD PORT REPLICATOR
   The ThinkPad Port Replicator can be attached to all ThinkPad 700/720/C systems.  The Port Replicator is designed to provide a convenient way to detach/re-attach all attached peripherals, for example, a printer, when the "portable" computer is taken from one location to the other. Installation of the port replicator is simply snapping onto the system expansion connector.  No additional features are required for use.  The Port Replicator extends the bus signals of the system expansion connector to a keyboard/numeric keypad, a mouse, an external display, a parallel and serial (9-pin) connectors. The system AC adapter can be put in the plug guide.  Thus, the peripherals stay plugged into the Port Replicator that remains on the desk.  Removal procedure is simply done by using opening levers.  A wire or chain can be used to secure the port replicator on the desk.

KEYBOARD KEYGUARD: 
   This is a molded plastic keyboard overlay that has holes for each key and an integrated TrackPoint II and click buttons.  It allows a user with mobility problems/muscle control problems to steady a hand on the KeyGuard and press the key by reaching through the related hole.
