<WRAP clear></WRAP> + + + ===== Installation of "Gotek" Floppy Drive Emulator (running "FlashFloppy") ===== + + There are several articles/videos on the Internet on retrofitting a "Lotharek" HxC floppy emulator to the analyzer. + + Below, the steps to use one of the newer "Goteks" (with the latest 435-based MCU and an OLED display) are outlined. They usually come with "FlashFloppy" already installed. + + * Remove the existing 5.25 drive. + * Retrofit a 34-pin IDC connector to the 4145A Floppy cable (covered in the YouTube video below). + * Use a power adapter to connect the Gotek to the 4-pin Molex of the 4145A. + * Connect Pin 6 and Pin 34 on the floppy drive with a jumper wire. + * Format a USB stick for the FAT32 filesystem. + * Load the configuration and binary files for the boot disk onto the USB stick. + * To install the Gotek into the 5.25 bay of the 4145A, either use parts from one of the universal floppy drive adapter kits that can be found on eBay. Or create a custom adapter if you are mechanically skilled. + * Put everything together, turn the instrument on, and it should boot from the Gotek. + + Zip-file with the two configuration files and the binary file for the boot disk: {{:component_measurement:4145a:gotek_4145a.zip|Gotek FlashFloppy Files}} + + + Credits: + * The boot disk binary file ("DSKA0000.HFE") can also be obtained from here: https://github.com/exclusivelyhp/4145A. + * Article on putting together the "IMG.CFG" file: http://w6akp.com/projects:hp_4145a_virtual_floppy + * FlashFloppy site: https://github.com/keirf/flashfloppy + * Jared Cabot's video and helpful information with regards to the 1345A display: https://youtu.be/53asomSXkXQ?si=rld6QaL18WURdmna + + +
