We have the MAX cards working on their PC Planner software no problem. Our 6600 hasnt been updated, as you say its not released yet.
We can plan on the MAX charts on the PC Planner , export them to a user card ( not MAX) and import them to the 6600. Works fine.
The user card can't be the 128k version has to be the 2meg card.
3 weeks ago I seen the MAX version work on a 6600 in their offices in Hedge End, but they reckon its not quite right for release.
Happy New Resolutions!!! : RIBbing for the craic!!!
