- | ===== Qume ===== | + | Most 8" drives require an additional power supply for +5VDC, +24VDC, and sometimes 120/240VAC. |

+ | |||
+ | ===== 50-to-34 pin adapters ===== | ||
+ | |||
+ | Two options exist: the FDADAP, and custom cables. | ||
+ | |||
+ | ==== FDADAP ==== | ||
+ | |||
+ | The D Bit [[http:// | ||
+ | |||
+ | The FDADAP needs +5V, and can be Applesauce-powered via the PC Drive Cable Kit. | ||
+ | |||
+ | Connect a 34-pin IDC cable between the Applesauce and the "PC FDC" connector. Then, connect a 50-pin cable between the 8" floppy drive and the "8 INCH" connector. Recommended parts for constructing a 50-pin to 50-pin edge connector cable are: | ||
+ | |||
+ | * 3M 3415-0001 (50-pin edge connector) | ||
+ | * 3M 89150-0103 (50-pin IDC connector) | ||
+ | * 3M 3439-2 (edge connector polarizing key, optional) | ||
+ | |||
+ | The 50-pin cable can be made very short, if desired. There is also a 3D-printable [[https:// | ||
+ | |||
+ | Other similar adapter solutions [[https:// | ||
+ | |||
+ | ==== Custom 50-to-34 pin adapters ==== | ||
+ | |||
+ | If you are only reading 8" disks, if you can confirm your drive does not require the TG43 signal for writing, //or// if you are prepared to manually toggle the TG43 line yourself while writing a disk, it is possible to build an adapter cable yourself. | ||

+ | ===== 8" Drive Power Supplies ===== | ||
+ | |||
+ | The average single 8" drive requires at least +5V @ 1A, +24V @ 1-2A, and may also require -5V @ 100mA. The most common connector to supply these voltages is a 6-pin AMP Mate-N-Lok connector P/N 1-480270-0, utilizing pins P/N 60619-1 (qty. 6). | ||
+ | |||
+ | Some drives (such as the Shugart 850/851 and QumeTrak 842) also require 120VAC or 240VAC for the spindle motor, which runs continuously. For the mentioned drive, the connector is a 3-pin AMP P/N 1-480700-0 with pins 350550-1 (qty. 3). Some more modern drives do not require 120VAC/ | ||
+ | |||
+ | The D Bit [[http:// | ||
+ | |||
+ | Care must be taken to ensure the +5V supply to the drive is well regulated - otherwise, damage to the Applesauce may occur. | ||

+ | Jumper options on this drive are extensive. Be sure to review all settings if experiencing problems. | ||
+ | |||
+ | It can be convenient to configure the drive to not lock the drive door when accessing, especially when dealing with damaged, flaky, or moldy media. | ||

+ | Use of these drives is **strongly discouraged**. The cone/clamp hub mechanism applies too great of a clamping force, and can tear the hub out of the diskette, ruining the media. You have been warned! |
