I don't have one of those Expander cards, but the RWIII manual indicates that pins 1, 2, 3 & 13 on the row of 24 pins (1 is at the bottom) should be cut for a Rev-B 512K Expander that is being used on a RWbasic, RWII or RWIII. It also states that this modification is not required for the Rev-C 512K or 2M expander. A comical note says to count the pins carefully as they take a long time to grow back. :) I guess you need to know what Revision the Expander it is first, or hopefully someone has a manual on the Expander (if there ever was one), but there is no mention of pins 20 & 21 so I suspect they _SHOULD_ be there.
