The ThinkPad 720 and 720C systems have a IBM 486SLC2 50/25MHz microprocessor
and a math coprocessor socket for an optional Intel 80387SL processor.
Optional IC DRAM cards of 2MB, 4MB or 8MB are available. An optional
240MB HDD is also available to contain large operating systems and application
requiring a large storage space.
INTEGRATED POINTING DEVICE
TRACKPOINT II: The 720 and 720C has a TrackPoint
II 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
NIMH BATTERY PACK:
o Rechargeable battery pack for 4 to 8 hours (monochrome)
or 2.4 to 4.8 hours (color) of use, depending on operating, environmental
and application characteristics. When on AC power, an idle or operating
system unit can charge the battery in approximately 1.5 hours (monochrome/color).
The system internal quick charge takes approximately 1.4 hours (monochrome/color)
during Suspend and power-off with AC adapter connected.
o The battery pack is an internal power source to the computer
when the AC adapter is not available. The battery pack is rechargeable
and is charged using the AC adapter or the ThinkPad Quick Charger, which
can charge two battery packs simultaneously.
With a fully charged battery pack, the user can
operate the computer up to 8 hours (monochrome) or 4.8 hours (color) depending
on the application and the configuration usage. PC Cards that do
not support the power management function may cause the shorter battery
In summary, the battery operation
hours and charging hours are:
1.4 hours 1.4
1.5 hours 1.5
1.4 hours 1.4
6.0 hours 6.0
Hours (Range) (9)
8.0 hours 4.8
(8) Full battery.
(9) Power management and application dependent.
NIMH BATTERY PACK WITH POWER STATUS INDICATORS:
A rechargeable battery pack with five power status LED indicators and one
push button located on the front bezel of a battery pack. These five
LEDs show how much the battery power remains when the user is pushing the
button. In full-charged state, all five LEDs are lit. One LED
means about 20% of battery power. The battery operation hours and
charging times are the same as those of the standard NiMH battery pack.
QUICK CHARGER: The quick charger
has two slots to charge two battery packs simultaneously. Charging
begins on the first battery pack installed, then after it is completely
charged, the other installed battery pack is charged. A REFRESH BUTTON
is provided for each
battery pack slot to DISCHARGE the battery packs before charging them.
There are identifiers and indicators that tell the charging status for
each battery pack installed.
IBM THINKPAD PORT REPLICATOR
The ThinkPad Port Replicator can be attached to the ThinkPad 700 and
700C systems and the ThinkPad 720 and 720C 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.

9552 IDE Controller
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
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
