The HP 200LX (F1060A, F1061A, F1216A), also known as project Felix, is a personal digital assistant introduced by Hewlett-Packard in 1994. It was often called a Palmtop PC, and it was notable that it was, with some minor exceptions, a MS-DOS-compatible computer in a palmtop format, complete with a monochrome graphic display, QWERTY keyboard, serial port, and PCMCIA expansion slot.

Description

Size comparison with 2007 Apple iPhone

Input is accomplished via a small QWERTY-keyboard with a numeric keypad, enclosed in a clamshell-style case, less than about 25% of the size of a standard notebook computer. The palmtop runs for about 30–40 hours on two size AA alkaline or Ni-Cd rechargeable cells and can charge batteries (both Ni-Cd and NiMH) via a 12V DC wall adapter.

The HP 200LX has an Intel 80186 compatible embedded central processing unit named "Hornet", which runs at ~7.91 megahertz (which can be upgraded or overclocked to up to 15.8 MHz) and 1, 2 or 4 MB of memory, of which 640 KB is RAM and the rest can be used for expanded memory (EMS) or memory-based storage space. After-market updates can bring the memory chips to up to 64 MB, which frees the PCMCIA slot for modem or ethernet card use. The Silicom, Accton 2212/2216, Netgear FA411, and Sohoware ND5120 network cards were compatible. Being IBM PC/XT compatible and running MS-DOS 5.0 from ROM, the HP 200LX can run virtually any program that would run on a full-size PC compatible computer as long as the code is written for the Intel 8086, 8088 or 80186 CPU and can run using CGA graphics. It can also run programs written for the 80286 CPU, provided they do not require the use of protected mode. It has a 16-bit PCMCIA Type II expansion slot that supports 5 V at 150 mA maximum, a SIR compatible infrared port and a full serial port (but with a proprietary mini connector for space constraint reasons).

The built-in software suite runs from ROM and includes Lotus 1-2-3 spreadsheet, a calendar, a phone book, a terminal, Lotus cc:Mail and a capable scientific/business calculator (among other applications). With a large compactflash storage card and a serial mouse, even Microsoft Windows 3.0 can be run on the palmtop. Running Windows was limited by the hardware, and the maximum version that could be run was Windows 3.0 (in Real Mode). However, Word 1.x and Excel 2.x for Windows would run (since they could run in Real Mode), allowing for the authoring of MS Office format-compatible files. The 640x200 resolution CGA compatible 4-shade gray-scale LCD screen has no back light. An electroluminescent technology back light installation is available from a third party since 2004, but keen eyesight is still required to use the small palmtop effectively without resorting to using its 2x and 4x zoom modes.

Other Models

HP 95LX

Main article: HP 95LX

The HP 95LX (F1000A for the 512 KB, F1010A for the 1 MB model) introduced the basic design in April 1991. It was known internally as project Jaguar. It had a NEC V20 CPU (an enhanced Intel 8088 clone with Intel 80186 instruction set compatibility and an additional Intel 8080 emulation mode, running at 5.37 MHz), but was hampered in running PC applications because of its quarter-CGA resolution LCD screen and MDA compatible (instead of CGA) graphics chip. The HP 95LX for the most part only displayed graphics in a special LX graphics mode. It ran MS-DOS 3.22 and had Lotus 1-2-3 built in. It also included a CR2032 battery for memory backup when the AA mains ran out.

HP 100LX

The HP 100LX (F1020A for the 1 MB, F1022A for the 2 MB model),[1] also known as project Cougar, is the direct predecessor of the 200LX. It was released in 1993 and available in International English, U.S. English, French, German and Spanish variants with localized keyboard and messages.[1] It is almost the same, including the Hornet CPU and MS-DOS 5.0, but with earlier built-in application versions.

HP Palmtop FX

The HP Palmtop FX is a variant of the HP 100LX with up to 2 MB flashable memory in 1993.[2] FAT flash disk images could be created and written to drive F: by a special FLASHDSK.EXE utility.[3] According to one source, it was developed for a Korean insurance company.[4]

HP 200LX AIA

The HP 200LX AIA was a 2 MB double-speed variant of the HP 200LX manufactured for the insurance company American International Assurance.[5]

HP 1000CX

The HP 1000CX (F1203A, F1222A) is an economy version of the 200LX with its Hornet CPU but without any built-in software except the MS-DOS 5.0 operating system in ROM. It was in widespread use among, for example, Coca-Cola warehouse managers, who loaded their own logistics software onto the machine. It has a black clamshell, while the 200LX has a dark green casing.

HP OmniGo 700LX

The HP OmniGo 700LX (F1206A) was a project of the HP calculator branch in Singapore. The HP OmniGo 700LX is essentially a HP 200LX including its Hornet CPU redesigned to piggyback a Nokia 2110 GSM mobile telephone for wireless mobility. The HP 200LX motherboard was factory-modified to support a second PCMCIA slot for a Nokia Data Card. Owing to the relatively large size of the Nokia telephone, the HP OmniGo 700LX has a large, pebble-shaped casing, making it a handheld with a phone attached. The production of the HP OmniGo 700LX ceased after the Nokia 2110 mobile telephone was rendered obsolete by later telephones.

HP OmniGo 100

The HP OmniGo 100 (F1305A) was designed as a more sophisticated successor to the LX series, and incorporated the HP-12C calculator functionality. It was GUI based, controlled by pen input or keyboard. However, it lacked the versatility of running unmodified DOS programs. The normal operation mode was with DOS-based PEN/GEOS and Graffiti handwriting recognition. It was not widely accepted as a calculator replacement, and Palm and Pocket PCs became acceptable as PDAs. It was based on the Vadem VG230, a highly integrated system controller with 16 MHz NEC V30HL CPU, instruction set compatible with the Intel 80186.

Current usage

Although this product line was discontinued by HP in order to introduce their Windows CE product line (starting with the HP 300LX), a strong interest in this hardware continued. It was the last palmtop from HP which ran the MS-DOS operating system, for which there is much software from desktop PCs, and it came with a useful bundle of software including 1-2-3 and Quicken. Compared to machines with Windows-based operating systems such as CE, DOS programs are more compact and efficient and, with programs such as Software Carousel, many applications programs could be loaded at once.

Third-party upgrades, repairs and renovations are available to maintain and extend the device.[6][7][8][9]

Japan

Because of its small size, the HP 200LX was very popular in Japan, so much so that its demise prompted an open-source initiative to design and market an AMD Elan SC400-based replacement to fill its place. This 'Morphy One' club organization created blueprints for the device but no prototype was ever built for reasons which remain unclear. Some argue it was a scam scheme as hundreds of people lost deposits they placed on the new palmtop in advance. The project leaders argued that key electronic components were unavailable due to strong demand from the mobile telephone manufacturing industry.

Easter eggs

There are many easter eggs built into the HP 200LX. The known ones are listed as follows:

Hidden gallery

This easter egg is on the HP 200LX in the built in game, "Lair of Squid". During the startup screen of the game, if the user types the word "gallery" ("gallerie" on a French palmtop; "siegergalerie" on a German palmtop; "galeria" on a Spanish palmtop) he/she is placed in a "part" of the maze that contains photographs of the primary software developers that worked on the HP 200LX. The user may exit from this gallery by exiting through the door at the end of the corridor. The software developers in the photographs are listed starting from left to right, then left to right and so on as follows:

The last panel on the right of the corridor contains a thank you message:

“ Very special thanks to all the people in HP and all the companies that made this palm-top possible. The Felix S/W team ”

The photographs of the developers have been described as "a-maze-ing".

Self-test poem 1

This easter egg is in the HP 200LX self test mode. With the palmtop powered off, the user may press [ESC][ON] to start the self test mode, then cursor down to the display option. On pressing [ENTER] 14 times, to step through the various screens, the user comes to a screen of example text in the form of a limerick poem. The poem is as follows:

“ There once was this thing from HP

That fit in your pocket, you see.
A caveman would stare
And pull out his hair
And wonder, 'What could this thing be?'

 ”

Self-test poem 2

This easter egg is in the HP 200LX self test mode. With the palmtop powered off, the user may press [ESC][ON] to start the self test mode, then cursor down to the display option. On pressing [CTRL][ENTER], then holding down [ALT] while pressing [ENTER] 13 times, the user comes to a cryptic poem, relating to business issues faced by the software development team. The poem is as follows:

“ Felis Concolor

A funny thing happened on the way to the Forum
When I encountered a group in search of a quorum.
They came from a city, The Burg On The Wire.
If I tried to describe it you'd call me a liar.
They wanted to charge me a really quite large fee
For the dubious pleasure of sharing their treasure.
"I'm a very Good man (Mark my words if you can),"
"But, the Dickens, I say, I simply won't pay!"
And with poetry, then, I proceeded to bore 'em
Then proceeded myself on my way to the Forum.

 ”

Self-test poem 3

This easter egg is in the HP 200LX self test mode. With the palmtop powered off, the user may press [ESC][ON] to start the self test mode, then cursor down to the display option. On pressing [CTRL][ENTER], then holding down [SHIFT] while pressing [ENTER] 13 times, the user comes to an allegorical poem, about the history and future of the HP LX palmtops. The poem is as follows (note that the project names for the HP 95LX, the HP 100LX and the HP 200LX are 'Jaguar', 'Cougar' and 'Felix' respectively, and that 'Felix' was the first LX to include Quicken):

“ Nine lives has a Cat, and each Cat a name,

All of them different, none are the same.
Jaguar was first, it made quite a roar.
Cougar was next, oh, how it did soar.
Felix is third, my heart it does quicken,
Who knows what comes next, the clock is a tickin'.

 ”

Hidden development aid in 'More Applications'

This easter egg is in the built in System Manager of the HP 200LX. This 'easter egg' is probably more of a development tool than an easter egg, but, in any case, the user may display the function by first pressing the blue [&...] key to start 'More Applications'. The user may then hold down [ALT] while pressing [F9] 4 times, followed by [F10] once. As long as the [ALT] key is held down, the user will observe columns of data about System Manager compliant (.EXM) programs registered with the System Manager, along with other arcane program information.

Hidden hex calculator

The HP 200LX includes an undocumented calculator application named HEXCALC, written by Andrew Gryc. It provides arithmetical and logical operations in binary, octal, decimal and hexadecimal system. The utility can be added to the applications menu by an entry with the following fields:
