This is a pair of vintage Percom 5.25" floppy disk drives model RFD-40S1 master drive and model RFD-40A1 slave drive. Both drives are working fine, recently serviced. Both are Tandon TM-100 series single sided drives. Some cosmetic wear to the cases, no other known issues. I will include several reprints of various documentation to help with the use of these drives with your Atari 8-bit computer.

Sold as-is
