Description: A template from which to build ISA cards. The board dimensions around the edge connector are from an early IBM PC Technical Reference Manual (5150 or 5160). The rear bracket positioning has been measured from an original IBM floppy controller taken from an IBM 5150. This board was an excellent fit when test-fitted in an early Tandy 1000 (25-1000).
