By my fault. By my fault. By my grevious fault. Please disregard my blather about the need for the IBM whatever 60. I was the middle-man for a restauranteer whose point-of-sale computer had gorked and jumped to you guys without viewing his layout. Turns out it was a dinky running PC Dos. His 30 employees have been using scratch pads. Forgiveness is begged. .. harry ..
