I will pay $25 each for PC 3.5 inch 720K double-density disk drives. These drives were first produced in 1984. In 1987 the 1.44 Meg high density drives were introduced. Unfortunately, I can not use the higher density drives with an Atari ST computer. If you have Atari ST computer equipment currently located in storage, I might be interested in making an offer. I especially would like to buy any SF314 external disk drives. However, I would like to avoid collecting those old CRT Atari monitors. I am currently using a modern flat screen monitor (it was a challenge to find one that can display low, medium and high ST resolutions). Thanks, Ted Skrecky Former Atari ST Software Librarian for Garden City A.C.E. (Victoria, BC) Note: Atari also produced SF354 external disk drives. These are single sided drives (360K only). If you have any of these units, the drive belts would have long ago “decomposed.” However, replacement drive belts are available from Best Electronics in the United States.
