510 Series Features
3.5-inch Floppy Disk Drive (FDD) Module
The Toshiba 510 Series Personal Computer uses extensive Large Scale Integration (LSI), and Complementary Metal-Oxide Semiconductor (CMOS) technology to provide minimum size and weight, low power usage and high reliability. The computer incorporates the following features and benefits:
Microprocessor - This
computer uses an Intel Pentium processor 133 MHz with VRT (Voltage
Reduction Technology) that operates at 2.9/3.3 volts. The math
co-processor and 16 KB cache memory are integrated into Pentium.
Cache memory - A 256
KB level-2 cache memory is provided in pipe-line burst SRAM.
Hard disk drive - The
510CDT has a 2.1 billion byte (2.02 GB) removable HDD pack. The
510CDS has a 1.3 billion byte (1.26 GB) removable HDD pack.
Selectable Bay - This
feature provides for connection of either a Floppy Disk Drive
(FDD), a CD-ROM, a second HDD module, or a secondary battery.
The FDD supports 3.5-inch 2HD (1.44 MB) disks and 2DD (720 KB)
disks. The FDD module can be connected to an external FDD port
with an attachment when another module is installed in the selectable
bay. A full-size, average 10-speed CD-ROM drive contains an ATAPI
(AT attachment packet interface) interface controller, and supports
the following formats: audio CD, photo CD, ISO 9660, and CD plus.
An optional 2nd HDD has 1.3 billion byte (1.26 GB) capacity. Using
an optional 2nd battery adapter, a battery pack can be installed
in the selectable bay to double the battery and operating time.
Memory - This computer
comes standard with 16 MB of EDO (Extend Data Out) DRAM. This
includes 640 KB of conventional memory and 15488 KB of extended
memory.
Display - The 510CDS
has a 12.1-inch DSTN (Dual-scan Supertwist Nematic) color LCD
with 800 x 600 pixels. The 510CDT has a 12.1-inch TFT (Thin Film
Transistor) color LCD with 800 x 600 pixels. The built-in display
controller supports full color capability and up to 1280 x 1024
resolution on an external monitor.
Keyboard - An-easy-to-use
82/84-key keyboard provides a numeric keypad overlay for fast
numeric data entry or for cursor and page control. This keyboard
supports software that uses a 101- or 102-key enhanced keyboard.
Batteries - This computer
has three different batteries: a Lithium-Ion main battery, a backup
battery (for memory backup), and an RTC battery (Real Time Clock).
Expansion memory slot
- An optional 8, 16, 32, 48, or 128 MB memory module can be installed
in the memory slot.
Parallel port - This
port can be used to connect a Centronics compatible printer or
other parallel device. The port supports ECP (Extended Capabilities
Port) conforming to IEEE·1284.
Serial port - The serial
controller is 16550UART compatible. This standard, 9-pin, serial
port can be used to connect such serial devices as a serial printer,
serial mouse, or external modem.
External monitor port
- The female, 15-pin, D-shell connector can be connected to an
external SVGA monitor. This computer supports VESA (Video Electronics
Standards Association) DDC (Display Data Channel) 2B compatible
functions.
PS/2(TM)
mouse/keyboard port - Either a PS/2 compatible keyboard or a PS/2
compatible mouse can be connected to this port.
PC card slot - The PC
card slot can accommodate two Type II (5.0mm) cards or one Type
III (10.5mm) card, which support PCMCIA Release 2.01 standard.
These slots are ready for advanced cards, including PC card 16's
multifunction cards and CardBus 32-bit cards as well as the Zoomed
Video (ZV) port, which is dedicated to high-performance video
data transfer such as MPEG video play back.
Docking interface port
- This 240-pin port enables connection of an Enhanced Port Replicator
II or a Desk Station V Plus. The Enhanced Port Replicator II duplicates
the following ports on the computer: PS/2 keyboard, PS/2 mouse,
serial port, parallel port, external CRT, audio line-in, audio
line-out, headphone, and microphone. It also provides a joystick
port and two additional PC card slots (Type III). The Desk Station
V Plus includes the features of the Enhanced Port Replicator II
and the following additional features: two PCI/ISA bus and one
PCI bus expansion slots, one 5.25-inch drive bay, one selectable
bay, and one on-board SCSI-2 (Small Computer System Interface)
controller.
External FDD port -
The external FDD port lets you connect an external FDD when a
CD-ROM drive, second HDD, or second battery is installed.
AccuPoint - The pointer
control stick, located in the center of the keyboard, provides
convenient control of the cursor without requiring desk space
for a mouse.
Serial infrared port
- This computer incorporates two infrared ports located on the
front and back. These ports are compatible with IrDA1.1 (Infrared
Data Association) FIR (Fast Infrared) standard, which enables
cableless 4 Mbps data transfer.
Sound System - The sound
system is compatible with Sound Blaster(TM)
Pro(TM) and Windowsâ
Sound System. This computer is equipped with a microphone, stereo
speakers, and the following jacks: audio line-in, audio line-out,
headphone, and microphone.

1. Determines if the AC cable or battery is connected to the computer.
2. Detects DC output and circuit malfunctions.
3. Controls the Battery icon, and AC IN icon.
4. Turns the battery charging system on and off and detects a fully charged battery.
5. Determines if the power can be turned on and off.
6. Provides more accurate detection of a low battery.
7. Calculates the remaining battery capacity.
8. Detects Ring Indicator (RI) signal for Auto Power On Function.

The computer has three types of batteries:
Battery specifications are listed in Table 1-9.
| Main battery | Lithium-Ion | ||
| Backup battery | Nickel Metal Hydride | ||
| RTC battery | Nickel Metal Hydride |
The removable main battery pack is the computer's main power source when the AC cable is not attached. The backup and main battery maintain the state of the computer when you enable AutoResume.
Battery charging is controlled by a power supply microprocessor that is mounted on the PCI board. The microprocessor controls whether the charge is on or off and detects a full charge when the AC cable and battery are attached to the computer. The system charges the battery using quick charge or trickle charge.
| Quick charge 1 (power off) | About 3.5 hours |
| Quick charge 2 (power on) | 10 hours or longer |
NOTES:
The backup battery maintains data for AutoResume. The power source used to back up the AutoResume data is determined according to the following priority:
AC source/cable > Main battery > Backup battery
The backup battery is charged by the main battery or the AC adapter when the AC source/cable is used to power the computer.
Table 1-11 lists the charging time and data preservation period of the backup battery.
| Charging Time | |
| Data preservation period (full charge) |
The RTC battery provides power to keep the current date, time and other setup information in memory while the computer is turned off. Table 1-12 lists the charging time and data preservation period of the RTC battery.
