                         WIPING - NICHIBUTSU 1982
                         ------------------------

This was a game that I though was amazing at the time. The screen consists
of a 'carpet'. You play a vacuum cleaner that has to clean up the bugs
on the carpet. There are a number of 'rugs' that you can use to kill
baddies ( go over them and they roll backwards - killing all the baddies
behind ). There are also various items hidden under the carpet which you
can collect for various bonus points.

I think Nichibutsu must have suffered badly from piracy as nearly every
small chip on the board has it's Id. scraped away.

The main processor is a Z80.

Other interesting chips are:

SH3-555, M58725P, SH2-102.

The PCB is an original two-layer board and was not particularly common
even when it was released. The board serial No. is 06977.
