This is an educated guess, but I assume that the Supercalc package may have a 'terminate and stay resident' portion which then causes any further programs to be loaded above the lower 128K of memory which must be shared with the video display circuitry (this only holds true if your friend's PCJr has additional memory above 128K.) Memory in the 0 - 128K range is much 'slower' due to the display circuitry's need for the addition of 2 extra wait states per memory access. -- /Steve Dyer dyer@harvard.harvard.edu harvard!dyer
