As a hobby I have collected over the years many Apple II items (mostly from eBay in its early years) and they are taking up space. To make room for my family I have sold some items here a while ago and I am now selling more of them. My first computer was an Apple II+ clone and so I know something about these items. I'll try to answer questions to the best of my knowledge.
This is the Hard Disk 40SC (Model M2644) from Apple Computer circa 1986. It was one of Apple's first generation SCSI (Small Computer System Interface) based hard drives for the Apple II as well as the Macintosh family and other third party computers using an industry standard interface. For an Apple II plus, IIe or IIgs to access storage in this external SCSI device, a SCSI card, cable, terminator (depends on configuration) and power cord are needed. The latter three are included with the hard disk. This hard disk has 40MB storage and is made in U.S.A.. More information about this storage device is available here. A historic item great for the Apple II collectors and enthusiasts.
This particular unit is in good cosmetic condition. The case has yellowed due to sunlight exposure and there is a crack about one centimeter wide at the back as pictured. Inside the case is a Quantum Q250 5.25” hard drive that is also made in U.S.A. and a Sony CR-43 switching power supply (Part No. 062-0412). I don’t have a SCSI card handy to test this unit but I did power it on. Both the power LED and fan came up and the drive made the normal spin-up and calibration noises. I left the unit on for two hours and there was no observable abnormality. Due to the nature of vintage electronics I could not guarantee anything about this unit. There is no refund or return.
Includes: used Hard Disk 40SC (serial no. F73703UM2644) as pictured with 40MB storage, power cord, SCSI system cable and active terminator. Specifications: 100-240V~, 50-60Hz, 1.0A, 50W. A guide for servicing the unit could be found here.
