Online version of Ajax for ZX Spectrum. Ajax (A Jax or A-Jax) is a vertically scrolling shooter released in arcades by Konami in December 1987. Similar to Contra and its "Gryzor", there was a European release of the game called Typhoon, which is the name used for Imagine Software's ZX Spectrum, Amstrad CPC, and Commodore 64 ports. The players control a "Tom Tiger" helicopter (in the 2D stage) and later a "Jerry Mouse" fighter jet (in the 3D stage), and shoot enemies in the air and bomb them on the ground, collecting power-ups and defeating bosses to advance levels. The game takes place in a fictional 2007 where the Earth has been conquered by alien invaders. The player combats the occupation forces using vehicles under operation code named 'A Jax' created to liberate the Earth...

Sinclair ZX Spectrum
Online emulated version of Ajax was originally developed for the ZX Spectrum an 8-bit personal
home computer released in the United Kingdom in 1982 by Sinclair Research. Referred to during development as the ZX81 Colour and ZX82, it was launched as
the ZX Spectrum by Sinclair to highlight the machine's colour display, compared with the black and white display of its predecessor, the ZX81.
The Spectrum was released as eight different models, ranging from the entry level with 16 KB RAM released in 1982 to the ZX Spectrum +3 with 128 KB RAM and
built in floppy disk drive in 1987.
The Spectrum is based on a Zilog Z80 A CPU running at 3.5 MHz (or NEC D780C-1 clone). The original model has 16 KB (16×1024 bytes) of ROM and either 16 KB or 48 KB of RAM. Hardware design was by Richard Altwasser of Sinclair Research, and the outward appearance was designed by Sinclair's industrial designer Rick Dickinson.
Video output is through an RF modulator and was designed for use with contemporary television sets, for a simple colour graphic display. Text can be displayed using 32×24 characters from the ZX Spectrum character set or from a set provided within an application, from a palette of 15 shades: seven colours at two levels of brightness each, plus black. The image resolution is 256×192 with the same colour limitations.
