I had a quick glance at it just to see if it connected , but I didn't play with it I must admit.
Bit more info:
Backpack CD-ROM (External/Parallel Port) from Micro Solutions
The Backpack CD-ROM drive has a proprietary parallel port interface and is not automatically recognized by Windows or Windows NT 3.51 and 4.0. Current Backpack CD-ROM drive models can use a 32-bit protected-mode driver obtainable from the manufacturer for compatibility with Windows and Windows NT 3.51 and 4.0. This driver can be downloaded from the Software Library at Micro Solutions' Web site at:
http://www.micro-solutions.com This 32-bit driver loads under SCSI Devices and appears in Device Manager in Windows or Control Panel in Windows NT.
The Backpack CD-ROM drive 16-bit real-mode driver can also be used as an alternative in Windows if it is loaded in the Config.sys file and Mscdex.exe (or equivalent) is loaded in the Autoexec.bat file. Early models of Backpack CD-ROM drives (single-speed model 160550 and double- speed model 162550) must use the 16-bit driver, as they are not compatible with Micro Solutions' 32-bit driver. Therefore, these early models of Backpack CD-ROM drives are not compatible with Windows NT 3.51 or 4.0.
If Windows or Windows NT still does not access the Backpack CD-ROM drive, or for information about driver parameters, configuration options, or Windows NT installation steps, please refer to the driver documentation or check the Technical Support area of Micro Solutions' Web site at
