AppleDisk 5.25 / Compatibles (19 Pin)

DB-19 Connector version.

Drives that fall into this category are the Apple DuoDisk, Apple UniDisk 5.25", AppleDisk 5.25", any converted 20 Pin drives and many drives offered by other vendors with a DB 19 cable and daisy chain pass through port. The DuoDisk does not offer the pass through port because it is a 2 drive unit and since the 5.25" is always the last device on a drive chain, it is not needed.

Compatibility:][, ][+, //c, IIgs¹, //e, Laser 128, Franklin Ace 500

(With either a DB-19 ('DuoDisk' / Apple 5.25" Controller)
or a smartport (drive port) based computer such as the //c, IIgs, Laser 128, Franklin

DoNOT to plug these drives into any connection with the power to the computer ON! Bad Things do happen when you do this.

*NOTE:20 pin drives that have been converted are only compatible with the ROM 01 IIgs. NOT the ROM 03,//c+²or //e Emulation Card. See note(s) below.

NOTE:The Apple //c+², the ROM 03 IIgs and//e Emulation card require the Apple Platinum "AppleDisk 5.25" Drive. Model #A9M0107.

Uses:Can be used as first or second drive¹.

Storage:The Drive is compatible with ProDOS, DOS 3.3, Apple Pascal 1.2/1.3 & Apple CP/M It is a single sided,double density drive,It stores 143 K of information, or 560 Sectors of DOS 3.3, 280 ProDOS Blocks. This is a Apple GCR Device only and can not read any other formats even with additional software or hardware.

Common problems occurred using this device:
Heads need cleaned
Speed Adjustment gets slow/faster.
Plugged into the computer with the power on. If this is done on a //c or IIgs you will kill the 341-0041 chip. (Known as the IWM or Incredible Woz Machine)

1) This drive does NOThave a "daisy-chain" port on the back of the drive. This means this drive must be the last drive on a chain or the only 5.25" drive. It can not be the first drive in a set of 2.

2) It seems that this condition sometimes may not apply to the //c+, depending on the date of manufacture of the computer,this should be approached on a case by case basis. If the drive works with AppleWorks 2.0 & ProDOS 8 1.7 & up, there should be no problems.
