Two alternatives – X500 and NotePAC-III
If you need a portable laptop-style computer with an expansion slot or two, there are not many optionsâŠ. Thereâs the Portexa NotePAC-PRO and the Getac X500 Server. In this article, we will look at the similarities, differences, and suggested applications. Disclaimer – we cannot sell Getac X500âs – but this will attempt to be fair and unbiased. Members of our staff have extensive experience using and modifying the Getac X500 and have a healthy respect for it.
The X500 (Launched June 2011) is 16.1″ x 12.6″ x 4.6″ (933.2 cubic inches) and the NotePAC-III-PRO-V (Launched February 2019) is 16.75âł x 12âł x 4.5âł (904.5 cubic inches).
The NotePAC of course does feature a triple display monitor, so itâs not quite apples to apples.
The NotePAC-PRO has two PCIe expansion slots as standard, whereas the X500 is expandable using a âsliceâ that replaces the bottom cover (the dimensions listed include the slice). The X500 slice can be PCI or PCIe, so if you need to support a legacy PCI card then the X500 is the one to choose.
Typical configurations of the NotePAC are considerably more powerful than the X500 and include an Nvidia Quadro RTX4000 graphics card in one of the PCIe slots.

NotePAC – 3 x 17.1â for (5760 x 1080)
Graphics
X500 – Intel HD 630 or NVIDIA Quadro P2000
NotePAC – Aspeed AST2500 or NVIDIA Quadro RTX4000
“A major advantage of the NotePAC is the 144Hz refresh rate on all displays as standard which allows the use of 3D imaging for various uses including targeting”
Displays
The Getac X500 has a 15.6â FHD (1920 x 1080) display with âQuadraclearâ filters to give it some usability in sunlight. The NotePAC-III-PRO-V has more than three times the screen real-estate, with 3 x 17.1â FHD displays for a total screen area of 5760 x 1080.
The NotePAC-III-PRO-V is the most powerful computer in itâs class. Triple screen portable computers with 16 core Xeonâs and expansion slots are inherently both powerful and require external powerâŠ. Until now!
An additional machined aluminum chassis attaches to the NotePAC-III-PRO-V behind the main chassis, and out of view when using the system. Six x 81Wh batteries give a run-time of over four hours*, without replacement. Using an external charger, unlimited battery powered performance is possible. (With everything maxed out, 100% CPU utilization and Passmark system test maxing out the stress, the battery still lasts for 1.5H.)
Physically mating to the NotePAC-III-PRO-V to form a single transportable package means the system is still robust, reliable and ergonomic to use. The Power PAC chassis is less than 2.75â deep.
The external PSU is a 600W 100-240V AC-DC adaptor putting out 19V and 31.6A through a mil-spec power connector.
Weight: Battery chassis without batteries: 13.2lb, with six batteries: 19.8lb
Includes: USB cable, Power cable, DVD driver.

“What sets the NotePAC-III apart is its combination of very high performance, extreme connectivity and reliable operation. Now it can operate for hours on battery power!”
Many security and surveillance missions rely on video. They need to monitor, capture, and disseminate video feeds. If a picture tells a thousand words, then a video is a library full of information. Capturing, processing, and evaluating video footage in a mobile environment can be challenging. Portexa now has a video capture laptop that makes deployed information gathering and video analysis a reality.
The NotePAC-III is a triple screen portable laptop. Machined from aluminum, and with high-end graphics and a video capture card designed for use in theatre. The NotePAC-III has passed Mil-Std 461 (EMC/EMI), DTE-901E (Shock/Torpedo Strike) and 810G (environmental).
“We are proud to have helped develop this excellent deployed solution.”

The latest touch screen technology is now available on large deployable workstation screens.The ACME MegaPAC is now available with Projected Capacitive Touch screens.Single, dual and triple screen workstations are available, and whichever system suits your needs, all screens support multi-touch input.
Almost everyone today is using touch-enabled mobile devices, tablet devices, or laptops on a daily basis. Multi-touch capabilities are merely table stakes now in mobile computing devices, and the gaming or signage industries.
Touch screens on mobile devices were revolutionized in 2007 when Apple released the first iPhone.Of course, Apple did not invent the technology, but it was the first time it was made available on a mass-market device.What made the iPhone tech interface different?Gestures, pinch and reverse pinch- to zoom out and in, swiping, etc.Before that, touch devices were restricted to single points (like clicks).
Now multi-touch gestures are available on the 24â displays of the MegaPAC portable workstation.
If we take a look at the original touch-screen technologies we can trace the evolution and understand the technology behind multi-touch displays:
Some of the earliest touch displays used infra-red beams of light in a grid.Sensors would ordinarily âseeâ the beam, but when a finger was placed on the display, it broke one or more beams, giving the touch screen controller an X & Y coordinate for the âbreakâ and provide a âtouchâ input.This technology is still in use as it allows the display glass to be made really tough, unlike the restive and capacitive alternatives.
IR Touch screens are suitable when a harsh environment (for example one that will be used by the public) is expected.They are:
Vandal-proof, wear-resistant
Maintenance-free, longer life expectancy
Versatile touch object (Pointer or finger or glove)
Super transparency (no membranes between the display and user)
Operable in various light conditions, indoors and outdoors
These sorts of touch displays are usually found in POS, ATM, Kiosks, gaming machines, and industrial control systems.
Touch Screen Technologies
Resistive touch screens
Resistive touch screens work by sensing the closing of a contact between two conductive membranes.There are typically an array of dots, visible upon close inspection, that holds the two membranes apart until the ringer or pointer closes the gap by deforming the membrane.This highlights one of the advantages of resistive screens over capacitive technologies – the pointing device does not need to be conductive, so a fingernail, a glove or a stylus can all work.Resistive touch screens can be quite precise and donât suffer from calibration drift as much as some capacitive screens.
Disadvantages are that there are at least two layers of membrane – typically plastic – between the display and the user, which reduces light output, and therefore reduces brightness.Over time, the flexible membrane can become fatigued and âcloudyâ further reducing display clarity.The other big disadvantage is that resistive touch screens can only detect a single pressure point – so there are no multi-touch gestures like pinch to zoom.
Surface acoustic wave
Surface acoustic wave touch screens work by sending an ultrasonic wave (ultra-sound wave) across the surface of the glass.Sensors detect the reflected wave and in some cases the attenuated wavefront that is caused by the pointer or finger.This is then translated into an X-Y coordinate for the touchpoint.
Traditional capacitive touch
Otherwise known as surface capacitive – work by detecting a change in capacitance of the field in front of the screen caused by a conductive entity of some sort.Usually a finger.Capacitive touch screens are commonly made of two layers – a surface insulator and a transparent conductive layer below it. As the human body is an electrical conductor when the touch panel is touched with a finger the electrostatic field of the panel is distorted.The touch screen controller then decodes the changes in capacitance and returns a touchpoint to the system. The advantages are that there is no membrane that needs to flex, so the touch-screen should last longer.Disadvantages include possible drift over time on large displays, which require periodic re-calibration.Because the sensor is a glass panel, there is less visual degradation than with resistive screens.
Projective capacitive touch
Instead of one capacitive sensor, there are many, usually on two layers of transparent conductors.
Projected Capacitive Technology (PCT) is fast becoming one of the most prevalent touch technologies for touchscreens. PCT technology is what allows us to tap, pinch, zoom, and scroll with various gesture controls and using multiple fingers, and can be used in a wide range of applications from consumer devices to commercial products.
PCT devices identify touch by measuring the capacitance at each addressable electrode in a dual-layer grid. When you touch the surface of a capacitive device, there is a disturbance in its electrical field (capacitance), which allows the device to determine when and where the touchpoint occurred.
PCT technology uses two main types of sensing methods, self-capacitance and mutual capacitance, each having its own advantages and disadvantages. In short, self-capacitance devices offer a higher signal strength and sensitivity to touch but does not support multi-touch (more than 2 touch-points) like mutual-capacitance devices.
âProjected capacitive technologies detect touch by measuring the capacitance at each addressable electrode. When a finger or a conductive stylus approaches an electrode, it disturbs the electromagnetic field and alters the capacitance. This change in capacitance can be measured by the electronics and then converted into X,Y locations that the system can use to detect touchâ ( from 3M)
ACMEâs addition of PCT technology to the MegaPAC results in a superior portable computing platform with a durable, UHD multi-touch touchscreen. The MegaPAC is a high performance, high-fidelity interactive solution that meets customers’ expanding user interface requirements.

PCI Express, PCIe, or Peripheral Component Interconnect Express, can be a somewhat complicated computer specification. When your computer first boots, PCIe is what determines the devices that are attached or plugged into the motherboard. It identifies the links between each device, creates a traffic map, and negotiates the width of each link. This identification of devices and connections uses the same protocol as PCI, so no changes were required when changing from PCI to PCIe in either software or operating systems.
A PCIe connection consists of one or more (up to sixteen, at the moment) data-transmission lanes, connected serially. Each lane consists of two pairs of wires, one for transmitting and one for receiving. There are 1, 4, 8 or 16 lanes in a single PCIe slot â denoted as x1, x4, x8, or x16. This is the difference between PCI connections which are parallel (32-bit or 64-bit bidirectional parallel bus) and PCIe which is basically a serial version of PCI.
PCIe is a multi-layered protocol â the layers being a transaction layer, a data link layer, and a physical layer. The Data-link layer is sub-divided to include a media access control (MAC) layer. Each lane consists of two unidirectional differential pairsoperating at 2.5, 5, 8 or 16 Gbit/s, depending on the negotiated capabilities. While on the other hand, transmit and receive are separate differential pairs, adding up to a total of four data wires per lane.
Each lane is an independent connection between the PCI controller of the processor chip-set (Southbridge) or the processor itself (which is almost always the graphics card slot) and the expansion card. Bandwidth scales linearly, so a four-lane connection will have twice the bandwidth of a two-lane connection. Depending on the expansion cardâs bandwidth requirements, the slot may need to be sized accordingly.
A physical PCIe x16 slot can accommodate a x1, x4, x8, or x16 card, and can run a x16 card at x16, x8, x4, or x1. A PCIe x8 slot can accommodate a x1 or x4 or x8 card but cannot fit a x16 card. Just to confuse the matter further, there are different versions of PCIe interface. Itâs also possible that a motherboard may have multiple slot sizes and also different PCIe versions: 1.0a, 1.1, 2.0, 2.1, 3.0, 3.1, 4.0 and coming soon 5.0.

Why do PCIe Lanes matter?
Functions your CPUâs PCIe Lanes Control:
Onboard Video
PCIe 3.0 x16 Slot (usually for video card)
2/U.2 (on some Enthusiast Boards)
LAN (on some Enthusiast Boards)
Other functions use your CHIPSETâs PCIe bus lanes. Functions CHIPSETâs PCIe Lanes control may control:
SATA hard drives
Onboard Sound
Onboard RAID
Onboard Network Controller/LAN
All PCIe slots except the first one
Thunderbolt
2/U.2
Quoted amounts of PCIe bandwidth required by individual components:
8-16 Lanes â x16 PCIe Video Cards (Each)
8-16 Lanes â Other Specialized PCIe Cards
4 Lanes â M.2 Drive
4 Lanes â Thunderbolt (uses 4 lanes PCIe 3.0)
4 Lanes â Hardware Based RAID Controllers
2 Lanes (Each) â SSD Drives
2 Lanes â USB 3.1 (Gen. 2)
1 Lane â USB 3.0 (USB 3.1 Gen. 1)
1 Lane â Sound
1 Lane â Network Controllers
Which chips have the most PCIe lanes?
Different chips support different numbers of PCIe lanes. For example: Intel Core i5 or i7-8700K or i9-8950HK have up to 1Ă16, 2Ă8, 1Ă8+2Ă4 with a maximum of 16 PCIe lanes. In addition, the 6850K and up i7âs have 40 lanes. The Intel Xeon E5-4669 v4 has a maximum of 40 PCIe lanes at PCIe 3.0, whereas the E7-8894 v4 has âonlyâ 32 lanes (per processor). AMD has upped the ante with their EPYC CPUâs â they have 128 PCIe lanes 3.0.
In the tech industry today, what makes this really complicated is that motherboard manufacturers have to make their motherboards support a range of processors which may have different numbers of PCIe lanes supported. So a motherboard using an i7-6850K chip may have the capability to address multiple slots at x16, whereas with a âlesserâ chip ie. i7-8700K may be fewer lanes available, with only one slot being x16. Just to complicate things further, NVME and other types of expansions require PCIe lanes. With NVME being a must-have feature for a modern motherboard, there are now even fewer lanes available to the expansion slots.
Working out how to get the most out of a motherboard in terms of application performance becomes even harder when you need to choose how to connect to the real world. PCIe lane allocation can make or break the performance of high-speed boards like RAID controllers when they are operating near-maximum capacity (which is now possible due to fast SSD storage).
While there are some non-PCIe interface options being explored by computer manufacturers, they would also require major hardware changes. All in all, PCIe looks to remain crucial for a while longer, even while the form factor of the connection continues to evolve.
