The original TRS-80 drives have an edge connector, the GoTek a more modern (ish!) pin and socket connection. However, the trickier part is building or buying the right floppy disk cable. You will need to tap 5v from inside the TRS-80 to connect to the power connector on the GoTek. You may need to adapt for your specific model of GoTek and if you are using an OLED screen. The smaller rectangular hole was for the 3 digital LED, the larger for the USB key and buttons. I added a 5mm LED connected to the pins used by the existing LED on the GoTek. matched the GoTek model I had, using 10mm spacers to lift it up off the base and line up the USB and buttons. The exact spacings for mounting hole etc. I used 3mm thick black acrylic cut on a GlowForge. The plans I used to make my enclosure are included with the other files in this repo as FloppyDrivemk5.pdf. I removed the GoTek from the original casing, and installed it into a laser-cut acrylic enclosure the same size as an original floppy drive. This copy of TRS8Bit magazine has an excellent article covering all this in detail with with more authority than here. There are some more intructions in this video.ġ.5 Make a dontation to the FlashFloppy author. Here's a good set of instructions.ġ.4 Run the flash utility from ST Microelectronics and upload the firmware to the GoTek. I soldered in some pins to make this easier.ġ.3 Connect the GoTek to your computer using a USB-A to USB-A lead (a little unusual, but eBay to the rescue).

In order to use the GoTek you will first need to change the firmware to a new version called FlashFloppy.ġ.1 Download the latest firmware from the FlashFloppy Github site.ġ.2 Set appropriate jumpers on the GoTek. There are several variations, and before you buy one you should read the links on this page to make sure to you're buying one that is compatible.
The GoTek hardware can be found on eBay and Amazon for $20 or less. The GoTek was created to replace floppy disk drives in equipment such as musical instruments and industrial control hardware - but they have proved very popular with retro computer user, as they can be used to replace drives in systems from Amigas to TI-99/4As with convenient USB drives. It consists of a unit that accepts USB flash drives, a three digit LED display and two buttons (many users augment or replace these controls with OLED panels and rotary controls). Adding a GoTek to the TRS-80 Model 4Ī GoTek is a piece of hardware designed to physicaly fill the space that would have been taken by a 3.5 inch floppy disk drive. Today they are used mostly for nostalgic reasons. They run propritary disk operating systems but also CP/M. They are Z80 based, with up to 128Kb of RAM. They consist of a monitor, keyboard and floppy drives in one case with a very traditional "retro computer look", and continue to be popular with enthusiasts. The TRS-80 Model 4 computers are a family of systems from 1983, built and sold by Tandy/Radio Shack. TRS80gotek Configuring a TRS-80 Model 4 to boot from a GoTek floppy emulator to FreHD system
