However, we need to talk to you to be sure we supply the correct version for your computer. The programs are available to anyone at No Charge. Note: California Software Systems can also provide programs which copy all the files on an “Excellon Floppy” to either an IBM floppy or your hard drive in a single operation. You can then read the bottom side of the disk in any IBM PC compatible computer using this software program. Simply use your CNC-6 to copy files from the top to the bottom of an Excellon disk. Therefore you can only read the bottom (D2 or D4) side, not the top (D1 or D3) side, of an Excellon disk – unless you install a special, expensive, floppy disk controller, and additional software. The lowest density a standard IBM compatible floppy disk controller can read is 256 bytes per sector. All other tracks on the Excellon disk are written at 256 bytes per sector. Excellon writes the first track on the top side at 128 bytes per sector. This program works by re-programming the standard, IBM compatible, floppy disk controller to match the parameters of the Excellon disk.

Drive “B” must be a 1.44 Mb, 3 1/2 inch, drive. Logical Drive “A” must a standard 1.2 Mb, 5 1/4 inch, disk drive. Due to limitations imposed by Microsoft, it will not function under any version of Windows NT. You will need a standard PC with two floppy disk drives running under Windows 95/89/ME or DOS. It provides a simply way to read and copy files, one at a time, from a 5 ¼ inch, Excellon formatted disk, to an IBM formatted floppy.

This floppy copy program can be added to either our Graphical Drill/Rout or our Drill Room File Server Systems. Copy Excellon formatted floppy disks to IBM PC formatted floppy disks.
