At Pulsar we are always striving to improve our products and the electronic systems that drive them and we often find ways to improve the performance by means of firmware updates.
These upgrades are made available, free of charge. You will be charged for your new micro, upgrade kit or EPROM but you will receive a corresponding credit when we receive the old items back in good condition provided it is one of the reprogrammable 89C5X series we have used for the last 6-8 years. Please return your old items to Pulsar within 4 weeks of the upgrade invoice date in order to qualify for a credit (shipping charges non refundable). Thank you.
