NO 2: OXB431, NO2A43F/B43F (EC; Alphasense, UK, NO 2 sensor with O 3 filter to minimise the O 3 interference), NO2_3E50 (EC; Citytech, UK), and MICS2710/4514 (MOx; SGXSensotech). Excellent performance (R 2 ≈ 1) under laboratory conditions, while poor performance under field conditions was achieved that highlights the necessity for careful performance evaluation.

Atari začína na stope 0, voľné je to potom pre použitie po stopu 17. Ak sa pohybujeme v uvedených medziach tak je možné mať naraz na diskete programové vybavenie pre obidva počítače a je možné priamo nabootovať z diskety. Samotný voľný rozsah je dosť malý a preto sa napríklad dala využiť oblasť nad stopou 35 pre Atari.
