About This Book
Purpose
The options and adapters are the second part of the IBM RT PC Hardware Technical Reference
manual. They are to be used in conjunction with the
IBM RT PC Hardware Technical
Reference, Volume I.
Audience
The information in this manual is for reference. It is intended for hardware and program
designers, programmers, engineers, and anyone
else who needs to understand the design and
operation
of the IBM RT PC Product Family.
How to Use This Book
This manual is modular in format, with each module providing information about a specific
option or adapter available for the
IBM RT PC family of products. Modules having a large
amount
of text contain indexes.
The modules are grouped
by type of device. To find a specific module:
1. Locate the full length hard tab with the type of device (Displays, Communications, Storage
Devices, etc.) printed on it that describes the option or adapter you need information about.
2. Open the manual to that section.
3. Leaf through that section to find the proper module.

iv Advanced Color Graphics Display

Description
The Advanced Color Graphics Display is a high resolution color display that supports an
addressable format of 720 dots horizontally by 512 scan lines vertically. The display screen is
interlaced at a refresh rate of 46/92 Hz.
The Advanced Color Graphics Display has two attached cables. One cable provides the direct-drive
signal interface to the Advanced Color Graphics Display Adapter. The second cable provides ac
power
to the display. The display operates on 120 Vac, 50/60 Hz or 220 Vac, 50/60 Hz
depending on the model.
The display uses a 14-inch (diagonal) shadow mask color cathode ray tube (CRT). The
CRT and
associated analog circuits of the display are packaged
in an enclosure that allows the display to sit
either
on top of the mM 6151, on a nearby tabletop or desk with the IBM 6150. The display
enclosure includes a tilt
and swivel base, which allows the display screen to be adjusted by the user
for the best viewing conditions. The display
an operator control that provides brightness control
function and a power
on and off switch.
Operating Characteristics
Operating characteristics of the display are as follows:
Screen
• Etched surface for reduced glare
• 720 dots horizontal by 512 scan lines vertical.
Video Signal
• Two-level (on and off) video for 6 video lines
• Maximum bandwidth of approx. 25.7 Mhz
• Compatible with standard TTL driver.

Horizontal Drive
• Free-running horizontal oscillator
• Normally low, positive going TTL pulse
• Nominal horizontal frequency of 24.68 Khz
• Retrace blanking time of 8.0 usec.
Vertical Drive
• Free-running vertical oscillator
• Normally low, positive going TTL pulse
• Nominal vertical frequency of 92 Hz
• Nominal frame rate of 46 Hz.
• Retrace blanking time of 527.0 usec.
Operator Control
Size
• Brightness control adjusts brightness of displayed image. (Clockwise rotation of control
increases brightness.)
• Power on and off switch and light.
• Width 372 mm (14.6 in.)
• Depth 400 mm (15.7 in.)
• Height 360 mm (14.2 in.)

iv Advanced Monochrome Graphics Display

Description
The Advanced Monochrome Graphics Display is a high resolution monochrome display which
supports an addressable format of 720 dots horizontally by 512 scan lines vertically. The display
screen
is interlaced at a refresh rate of 46/92 Hz.
The Advanced Monochrome Graphics Display attaches to the
RT PC system unit through two
cables approximately 2.5 meters (8.25 feet) in length.
One cable provides the direct-drive signal
interface to the
RT PC Advanced Monochrome Graphics Display Adapter. The second cable
provides ac power to the display from the system unit. This arrangement allows the system unit
power switch to also control the power to the display and reduces the number
of electrical wall
outlets required to power the system. The display operates
on 120 vac, 60 Hz power line voltage.
The display uses a 12-inch (diagonal) high contrast monochrome CRT. The
CRT and associated
analog circuits of the display are packaged in an enclosure that allows the display to sit either on top
of the Model 10 system unit or on a nearby tabletop or desk with other RT
PC system units. The
display enclosure includes a tilt and swivel base which allows the display screen to be adjusted by
the user for the best viewing conditions. The display has only one operator control which provides
two functions: brightness control and raster switch (used only to verify operation of the display).
Operating Characteristics
Operating characteristics of the display are as follows:
Screen
Etched surface for reduced glare
720 dots horizontal by 512 scan lines vertical.
Video Signal
Two-level (on and off) video
• Maximum bandwidth of approx. 25.7 Mhz
Compatible with standard TTL driver.

Nominal frame rate of 46 Hz.
Operator Control
Size
Brightness control adjusts brightness of displayed image. (Clockwise rotation of control
increases brightness)
Raster switch (diagnostic aid) produces visible raster independent of video input. (Raster
switch function occurs at full clockwise rotation of brightness control)
