Any information appreciated before I forge ahead. You can use the original floppy controller to install a 720K drive on the PC-6300. The BIOS should be version 1.43. If you do not have this version it can be ordered for $35.00 from AT&T. You will also need DOS 3.3 so a DRIVEPARM line can be added in config.sys. Hope this helps! David R.
