L system

L system

Taito Corporation develops the L system and is the arcade game board which I adopted from 1988. JAMMA edge connector of the JAMMA standard conformity is equipped with. I adopt Z80 which is an 8 bits CPU as a main CPU, and the size of the board becomes a compact very basically (the size of the real board varies according to a game).

In addition, there are many things treated as "the exclusive board every each virtual game" which I cannot change of the ROM, but the conversion kit that the ROM exchange from a previous work is possible about "playgirl 2" released by hot ビィ is released (as for the ROM exchange from other works of the use of L system, impossible).

Depending on a game, the thing varying in the specifications of some boards exists, and a sub board for the track ball control is equipped with with the board of "the American horseshoe" when I give an example.

Specifications

It is the basic constitution of the L system as follows, and two CPU's are equipped with depending on a game (three in conjunction with a sound CPU in total), and sound chips may be different.

  • A CPU: Z80 @ 3.3MHz (I may be 6MHz depending on a game)
  • Sound CPU: Z80
  • Sound chip: YM2203
  • Video resoution: 320x224
