DECpc 1.44-MB 3½-Inch Diskette Drive

This document is an installation guide for the 1.44-MB 3½-inch diskette drive (RX23L) for DECpc computers, specifically covering Teac FD-235HF and Mitsubishi MF355F models. It outlines the package contents and provides crucial preliminary information, including a warning about static electricity and compatibility restrictions (not for early DECstation PC4-series models). The guide details jumper settings for both drive types, noting that they are factory-set but providing tables for reference. The installation process involves seven steps: setting jumpers, turning off and disconnecting the computer, removing the cover and locating the drive bay, mounting the drive, connecting data and power cables, running the system setup utility, and rebooting. Finally, it provides specifications for both drive models, including media type, operating/nonoperating temperatures, and relative humidity.
