The '''Aquarius''' is a [[home computer]] designed by Radofin and released by [[Mattel Electronics]] in 1983. Based on the [[Zilog Z80]] microprocessor, the system has a rubber [[chiclet keyboard]], 4 kB of RAM, and a subset of [[Microsoft BASIC]] in ROM. It connects to a [[television]] set for audiovisual output, and uses a [[cassette tape|cassette]] tape recorder for secondary data storage. A limited number of peripherals, such as a 40-column [[thermal printer]], a 4-color printer/plotter, and a 300 [[baud]] [[modem]], were released. The ''Aquarius'' was discontinued in October 1983, only a few months after it was launched.<ref name=":1">{{Cite news |last=Mace |first=Scott |date=23 Jan 1984 |title=Where is Logo taking our kids? |url=https://books.google.com/books?id=fC4EAAAAMBAJ&dq=InfoWorld+...John+Allen%2C+president+of+The+Lisp+Company...announcing+TLC+Logo%2C+which+could+run+on+the+Mattel+Aquarius...Today%2C+the+Mattel+Aquarius+is+virtually+off+the+market...&pg=PA49 |work=InfoWorld |pages=49 |quote=...John Allen, president of The Lisp Company...announcing TLC Logo, which could run on the Mattel Aquarius...Today, the Mattel Aquarius is virtually off the market...}}</ref>

==Development==
Looking to compete in the home computer market, Mattel Electronics turned to Radofin, the [[Hong Kong]] based manufacturer of their [[Intellivision]] consoles.<ref>{{Cite web |title=Mattel Aquarius |url=https://oldcomputers.net/aquarius.html |access-date=2024-09-21 |website=Steve's Computer Collection}}</ref><ref>{{Cite web |date=2006 |title=Player 3 Stage 3: Contender to the Throne |url=http://www.thedoteaters.com/p3_stage3.php |url-status=dead |archive-url=https://web.archive.org/web/20061109002827/http://www.thedoteaters.com/p3_stage3.php |archive-date=2006-11-09 |access-date= |website=The Dot Eaters}}</ref> ''Radofin'' had designed two computer systems. Internally they were known as "Checkers" and the more sophisticated "Chess". Mattel contracted for these to become the Aquarius and Aquarius II, respectively.<ref name=":0">{{Cite web |title=RADOFIN ELECTRONICS LIMITED AQUARIUS 2 |url=http://old-computers.com/museum/computer.asp?c=74&st=1 |archive-url=https://web.archive.org/web/20110720194428/http://old-computers.com/museum/computer.asp?c=74&st=1 |archive-date=2011-07-20 |website=OLD-COMPUTERS.COM}}</ref>

Aquarius was announced in 1982 and finally released in June 1983, at a price of $160. Production ceased four months later because of poor sales. Mattel paid ''Radofin'' to take back the marketing rights. Four other companies: ''CEZAR Industries'', ''CRIMAC'', ''New Era Incentives'', and ''Bentley Industries'' also marketed the unit and accessories.

The Aquarius was often bundled with the Mini-Expander peripheral, which added game pads, an additional [[ROM cartridge|cartridge]] port for memory expansion, and the [[General Instrument AY-3-8910]] sound chip. Other peripherals were the data recorder, 40 column [[Thermal printing|thermal printer]], 4 and 16 kB RAM cartridges. Less common first party peripherals include a 300 [[baud]] cartridge [[modem]], 32 kB RAM cart, four color plotter, and [[Quick Disk#Quick|Quick Disk drive]].

==Reception==
[[File:Haus der Computerspiele - Mattel Aquarius.jpg|thumb|Aquarius game cartridges and keyboard overlays]]
Although less expensive than the [[TI-99/4A]] and [[VIC-20]] home computers it competed against, the Aquarius was made a less attractive purchase by its comparatively weak graphics and limited memory<ref>{{Cite web |title=Mattel Aquarius |url=https://www.computinghistory.org.uk/det/502/Mattel-Aquarius/ |access-date=2024-09-21 |website=Centre for Computing History}}</ref> as well as the hidden cost of add-ons required to overcome the limitations of the base unit.<ref name='yc_aqua' />

Internally, Mattel programmers adopted Bob Del Principe's mock slogan, ''"Aquarius – a system for the seventies",''<ref>{{cite web |last=Klooster |first=Erik |title=Mattel Aquarius - home computer with the shortest career |url=http://computermuseum.50megs.com/brands/aquarius.htm |access-date=2020-01-28 |website=HISTORY OF HOME AND GAME COMPUTERS |quote=Besides that, the Mini Expander was equipped with the same sound chip (AY-3-8914) as the Intellivision. But that didn't appeal to the programmers: they almost considered it as a punishment to develop a game for the Aquarius. Programmer Bob Del Principe even invented this cynical slogan: 'Aquarius - system for the seventies!'}}</ref> which was a slight because the Aquarius was developed and released in the eighties. Of the 32 software titles Mattel announced for the unit, only 21 were actually released, and most of those were ports of [[Intellivision]] games, often inferior ports. Because of the hardware limitations of the Aquarius, the quality of many games suffered. The absence of any [[all-points-addressable]] graphics mode was so glaring that Radofin crafted the [[#Character set|character set for the Aquarius]] with many tiles and sub-tiles, as well as [[block graphics]] characters, so games could at least feign [[Sprite (computer graphics)|sprites]] and use [[semigraphics]]. It proved to be not enough.<ref name=":1" /> As [[COMPUTE!]] magazine put it:

"The Aquarius suffered one of the shortest lifespans of any computer—it was discontinued by Mattel almost as soon as it hit store shelves, a victim of the 1983 home computer price wars."<ref>{{Cite news |date=April 1985 |title=Mattel Aquarius Benchmark |url=https://archive.org/details/1985-04-compute-magazine/page/n19/mode/2up |work=COMPUTE! |pages=18 |issue=59}}</ref>

Decades after the spectacular market failure and exceptionally short original [[product life]] of the Aquarius, [[retrocomputing]] enthusiasts returned to this platform with renewed interest and intrigue, partly due to rarity and hacker interest in working within—and pushing—tight system constraints.  Multiple homebrew games were thus published scores of years after-the-fact,<ref>{{Cite web |last=Steenoven |title=Mattel Aquarius Games: Turmoil 2022 |url=https://www.vdsteenoven.com/aquarius/turmoil.php |access-date=2024-09-21 |website=Mattel Aquarius Home Computer}}</ref> and development and niche user interest in Aquarius software continues, using surviving original hardware, [[FPGA]] implementations, and [[emulators]].<ref>{{Cite web |title=Mattel - Aquarius Emulators |url=https://www.zophar.net/aquarius.html |access-date=2024-09-21 |website=Zophar's Domain}}</ref>

==Peripherals==
[[Image:Mattelaquarius.jpg|thumb|The Aquarius with attached expansion block including 4 kB RAM expansion and game cartridge inserted, controllers, and tape data recorder]]Despite its relatively short time on the market, Mattel Electronics and ''Radofin'' managed to have most of the announced peripherals available within a month or so of the release of the system. Some products never materialized beyond prototype phase, and some were available only in specific markets. Beginning in 2016, new user-designed peripherals began to show up, mostly on eBay or on vintage computer forums such as AtariAge.

==Interfacing==
[[File:Mattel-Aquarius-Computer-BR.jpg|thumb|The back of the Aquarius, showing the unidirectional serial printer port in the form of a [[TRS minijack]], the [[DIN connector|DIN]]-type external cassette drive connector, the TV channel 3/4 selector switch,<ref>per page IN7 (Introduction 7) of the Aquarius Guide to Home Computing, and also called channel selector on the Aquarius's Simplified Instruction Cards</ref> the TV output connector, and the hardwired power lead]]

The Aquarius manual did not contain detailed documentation on any of the ports available, but Aquarius FAQ files and later retrocomputing websites shared the ascertained information. 

===Cassette port===
The cassette port, although using the same 5-pin [[DIN connector|DIN 41524 connector]] as the [[TRS-80]], did not have the same pinout and thus was incompatible with readily available cables for the TRS-80, even though they physically fit the sockets on both the computer and cassette player. The Aquarius-branded cassette deck came with the appropriate cable.<ref name="FAQ">{{cite web |last1=Horvat |last2=Parrish |date=May 6, 2001 |title=Mattel Aquarius FAQ |url=https://archive.kontek.net/aqemu.classicgaming.gamespy.com/aqfaq2.htm |access-date=October 13, 2022 |website=ArchiveKontek.net |publisher=}}</ref>

The cassette port is a 5-pin female DIN 41524 connector

| 5 || Not used || MIC
|}

The MIC and EAR connections from the Aquarius each go to the tip/center of one of the two mini-plugs being attached to the recorder; Ground goes to the base/outside of both mini-plugs.<ref name = "FAQ" />

===Printer port===
The printer interface is a 3.5 mm [[Phone connector (audio)#Miniature size|mini-stereo socket]] with 3 lines (tip, ring, sleeve), the same as on the Mattel [[Entertainment Computer System]].  The Aquarius printers came with their own cables. The interface conforms to [[RS-232]] serial signal standards  (+12VDC/-12VDC), and with knowledge of its pinout it is possible to interface with RS232-compatible serial printers.<ref name = "FAQ" />  

Typical serial printers had [[D-subminiature|DB-25]] interfaces; some had [[D-subminiature|DE-9]] interfaces; and some [[Radio Shack]] (RS) printers had round 4-pin female [[DIN connector|DIN]] serial interfaces (with the pin sockets numbered left-to-right: 4, 3, 2, 1).

The following shows the pinout for the printer connector on the Aquarius, as well as for connection with the aforementioned serial printers:<ref name = "FAQ" />
{| class="wikitable"

|-
| Ring || Printer busy/data set ready (DSR) || Pin 20 || Pin 4 || Pin 2
|-
| Sleeve || Signal ground (GND) || Pin 7 || Pin 5 || Pin 3
|}

The serial transfer protocol is fixed to 1200 baud [[Serial port#Conventional notation|8N2]], and provided both carriage return and line feed commands to the printer; thus the printer needed to be set to not also execute a line feed on carriage return.<ref name = "FAQ" /> Because the Aquarius printer port used only a minimum number of pins (TxD/DSR/GND), the use of this port was unidirectional, from the computer to the printer (or other attached serial device).

== Aquarius II {{anchor|ii}} ==
Just after the release of the Aquarius, Mattel had announced plans for the Aquarius II.<ref name="pcw_1983_08">{{cite magazine |title=My Kind of Show |url=https://archive.org/details/PersonalComputerWorld1983-08/page/154/mode/2up |magazine=[[Personal Computer World]] |page=155 |quote=Following the unsuccessful launch of the Aquarius home computer last autumn its maker Mattel Electronics produced a re-vamped model, the Aquarius II, at the [Consumer Electronics Show].}}</ref> However, before this could happen, Mattel had returned the rights to Radofin and left the market.

In April 1984, a sample of the Aquarius II- now marketed by Radofin themselves- was reviewed by UK magazine [[Your Computer (British magazine)|Your Computer]], who quoted a price of £80 and considered it "a vast improvement over the Aquarius 1".<ref name="yc_aqua2" />

There is evidence that the Aquarius II reached the market in small numbers under the ''Radofin'' brand,<ref name=":0" /><ref>{{Cite web |date=2007-03-11 |title=Mattel Aquarius : Le chant du cygne |url=http://perso.orange.fr/rogue/aquarius.html |archive-url=https://web.archive.org/web/20070311211104/http://perso.orange.fr/rogue/aquarius.html |archive-date=2007-03-11 |access-date=2023-06-17 |website=ColecORIC}}</ref> and that it was  actively promoted in France, with press advertisements from its official distributor appearing there towards the end of 1984.<ref name="micro7_1984_12" /><ref name="loi_1984_11" />

In spite of this, it was also not a commercial success. Technically otherwise identical to the previous version, the Aquarius II came with a 16 kB RAM extension, mechanical keyboard and Extended BASIC{{Which|date=May 2025}}.<ref name=":0" />
