Use any PS2 mouse and just plug into Pest! |
Introduction PeST has been developed to meet the requirements of Atari ST users, specifically that Atari mice are now in short supply and that the feel of the original device sold back in the 80’s is showing its age. PeST is the acronym for PS2 enumerator for the Atari ST. It enables any PC PS2 mouse to be used with the Atari ST / STF / STFM / STE / Mega / Mega STE / TT / Falcon etc. The device is completely automatic and fully plug and play. Care has been taken to ensure that no movements of the mouse are lost. In the early stages of PeST’s development we tested similar interfaces offered by the competition. No two interfaces had the same feeling. We have been spoilt in recent years by more recent operating systems, in expecting the pointer on screen to move exactly relative to the mouse being handled. This was entirely our aim in developing PeST. If we were going to use it, and if we were going to be happy with it, it had to work! How it works PS2 3-byte packets of information are received from the mouse. These are analysed by a programmable computer-on-a-chip. The resulting information is reflected on the Atari ST’s mouse port. Effectively our device is a PS2 to BUS mouse converter. The computer-on-a-chip which performs the conversion has a similar amount of processing power to computers of the late 1970’s. It has 2 Kbytes of ROM and about 256 bytes of RAM, with a processing speed of about 1MIPS. The program necessary to make the interface work is about 700 bytes of optimised machine code. Pest is fully "plug & play" and requires no software or hardware mods to work. Speed can be changed between four modes up to 400% over the original ST mouse. |
