This document covers the SL100 and its predecessors the SL88 and the SL99. All the information has been re-worded to match the SL100. The various models come about basically as a result the availability of more capable versions of the microcontroller chips we use. In most cases everything gets significantly better, though occasionally there may be a minor compromise on a feature. In the case of the SL100 it has less endurance in the Shadow Memory.

The following table highlights the major differences between the products. What is not listed is very many features that are implemented in successive dialects.
