Notes Madge 1998 05 11 99 7 of 147 Sg_acpb6 Madge Technical Training Token Ring Desktop require the TROPIC chip set Madge developers designed a new set of adapters based on a Texas Instruments chip set which although functionally equivalent to the IBM standard actually was very different These new style adapters were and are called Ringnodes and because they have considerable processing power and a significant amount of memory on board it is possible to load the Madge SMART driver on to the card so saving DOS memory in the PC For this reason they are called Smart Ringnodes Once the breakaway from the IBM standard was seen to be successful the developers began to think the unthinkable that perhaps the Blue family didn t need the TROPIC chip set there might be better ways of emulating IBM token ring connectivity while maintaining full compatibility So later on Madge produced a different chip set for the Blue family which when used with Madge driver code can run much more efficiently and if Madge configuration software is used to set them up have more IRQs available To summarise the Blue adapters are 10096 compatible with their IBM equivalents for those customers who do not want to stray very far from the token ring main stream Blue adapters now use Madge technology for slightly better performance and if Madge s drivers are also used considerably better performance is available For the more adventurous the Smart Ri
