It really depends on what he wanted to design with it. Well, whatever, I believe 1) or 2) would be the most appropriate. >Your pricing and configuration information is faulty! >If you had FULLY understood what you THOUGHT you read in this passage, I >was indicating that a LAHEY version (not the $99 version) did perfom >this task. I noticed YOU didn't offer any suggestions here... Mentioning 'least expensive' and the breaking of the 640K limit they way you had, did make it sound like the $99 version broke that limit. The F77LEM manages to break the 640K limit by using what they call 'Overlays'. Overlays swap/pages memory so that more than 640K can be addressed. >John L.
