The screen is sized 66&nbsp;mm (2.6 in.), the same as the original [[Game Boy]]. It can display 64 [[Sprite (computer graphics)|sprite]]s at once, 16 per [[Scan line|scanline]], in up to 481 colors from a [[Palette (computing)|palette]] of 512.{{Citation needed|date=June 2008}} It has 8 [[kilobyte]]s of [[Random Access Memory|RAM]], and it runs a [[HuC6280]] [[Central processing unit|CPU]] at 1.79 or 7.16 [[megahertz|MHz]], same as TurboGrafx-16.{{Citation needed|date=September 2018}}

The TurboExpress had a [[backlit]] display. Handheld market leader [[Nintendo]] did not have a backlit handheld until the release of the [[Game Boy Light]] in 1998. Its keypad layout is similar to that of the original [[Game Boy]], with the unique addition of two "turbo switches" that engage two levels of high-speed controller button re-triggering to assist the player.{{Citation needed|date=September 2018}}

Due to a problem with faulty [[capacitor]]s (an industry-wide issue in the early 1990s), sound failure is a frequent problem with the TurboExpress, sometimes even in new systems.<ref>{{Cite web |url=http://www.pcenginefx.com/forums/index.php?topic=702.0 |title={title} |access-date=2008-01-17 |archive-url=https://web.archive.org/web/20080408105248/http://www.pcenginefx.com/forums/index.php?topic=702.0 |archive-date=2008-04-08 |url-status=live }}</ref> The screen used in the TurboExpress was another source for problems, though it was state of the art when it was released. The [[Liquid-crystal display|LCD]] technology used was still fairly new and the rate of [[Defective pixel|pixel failure]] was very high. Brand-new TurboExpress systems often had several bad pixels. Text is also difficult or impossible to read in certain circumstances, as many times fonts were written to be seen on a television screen, not on a small LCD screen. As a result, certain [[Role-playing game|RPGs]] and [[adventure game]]s can be difficult to play on the unit.{{citation needed|date=November 2014}}

The TurboExpress plays the same [[game cartridges]] as the TurboGrafx-16 home console.<ref name=":0">{{Cite news|url=https://ew.com/article/1991/03/15/1991-gadget-guide/|title=1991 Gadget guide|work=EW.com|access-date=2018-09-10|language=en|archive-url=https://web.archive.org/web/20151001084323/http://www.ew.com/article/1991/03/15/1991-gadget-guide|archive-date=2015-10-01|url-status=live}}</ref> Some TurboGrafx-16 [[HuCard]]s save game data to the internal memory of the [[TurboGrafx-CD]] unit, [[TurboDuo]], or TurboBooster Plus (a peripheral for the core TG-16 console). The TurboExpress lacks this internal memory and, as a result, is not capable of saving in this manner. Most games provide a [[Password (video games)|password save]] mechanism as an alternative.

The battery life is about three hours for 6 [[AA batteries]]. This is also a problem for other color and backlit or sidelit handhelds of the time, such as the [[Game Gear]] at 5–6 hours, the [[Sega Nomad]] at 2–3 hours, and the [[Atari Lynx]] at more than 4 hours. Nintendo's Game Boy had a 12- to 40-hour lifespan on 4 AA batteries.

===TurboLink===

The TurboLink allows two-player play. ''[[Falcon (video game series)|Falcon]]'', a flight simulator, includes "head-to-head" [[dogfight]] and cooperative modes that can only be accessed via TurboLink.<ref>{{cite magazine|title=Review Crew: Falcon|magazine=[[Electronic Gaming Monthly]]|issue=36|publisher=Sendai Publishing|date=July 1992|page=24|url=https://archive.org/details/Electronic_Gaming_Monthly_036|access-date=2018-03-03|archive-url=https://web.archive.org/web/20180729080951/https://archive.org/details/Electronic_Gaming_Monthly_036|archive-date=2018-07-29|url-status=live}}</ref> This technology was also used for ''[[Bomberman '93]]'' Com-Link multiplayer. Although it was released after the TurboExpress launch, very few TG-16 games offer co-op play modes especially designed with the TurboExpress in mind.{{Citation needed|date=September 2018}}

===TurboVision===
[[File:NEC-TurboExpress-wTurboVision.jpg|thumb|upright|The TurboVision TV tuner]]
TurboVision is a [[TV tuner]] adapter for the TurboExpress converting the TurboExpress into an [[handheld television]].<ref name=":0" /> The accessory was available at launch for {{US$|100|1990|round=-1}}.<ref>{{cite magazine|url=http://archives.tg-16.com/PLAYBOY/Playboy_1991_04.pdf|title=PlayBoy Collection|magazine=Playboy|publication-date=April 1991|via=tg-16.com|archive-url=https://web.archive.org/web/20170105223547/http://archives.tg-16.com/PLAYBOY/Playboy_1991_04.pdf|archive-date=January 5, 2017|url-status=live}}</ref> It allowed a player to either watch television, or go back to playing games with the flip of a switch; in other words, one may use the TurboExpress as a video monitor. It includes an [[RCA connector|RCA audio/video input]] for external [[composite video]] signals. Due to the widespread adoption of [[digital television]] and the [[HDTV]] standard, however, the adapter will no longer function as a television in most places due to the lack of any HDTV digital processing circuitry (the tuner can only process an [[analog signal]] for television). Due to this limitation, the TV tuner adapter is now relegated to a collectible for most people, although its RCA audio/video input function will still be operational (albeit limited with its low screen resolution).
