The Competition Pro and Zip Stick stand out as the better-quality options for these models were available with microswitches instead of the cheaper metal contact switches, although lower cost models from Quickshot, Cheetah, Sinclair, Commodore were very common in any gamer’s setup

Amiga Drawbridge Guide how to Read and Write Floppy Disks

First connect the interface and power cable to your floppy disk drive make sure that the pins are lined up correctly, then you connect the usb cable to the side of the interface, dont use too mutch force as mini usb connectors are fragile.

Connect the usb cable to a USB 2 or USB 3 port on your PC or Laptop, it recommended to use a port on your motherboard, Note that front panel case USB ports and hubs can cause errors so it better to connect directly to the ports at the back of your PC.

Software Download

Download the software from this link –

The drawbridge software is open source and free to download from the developer’s website below

One downloaded, extract the .rar archive DrawBridge folder to your windows desktop

inside the Drawbridge folder, run the software “DrawBridgeWin.exe” – By Double Clicking

If the interface has been detected correctly the COM Port: window will show a com number – this shows the interface is plugged in and detected

***The disk interface is setup as a Drawbridge Plus, you can check this by using the Diagnostics test

If its not set, then you can tick the DrawBridge Config… button and tick the Drawbridge Plus Option 

Disk Errors or disk’s not working

Trial and error is sometimes required to get a successful disk written, the most common errors are caused by bad floppy drives, dirty drive heads or bad / perished floppy disk, remember that most disk are now around 30 years old and the magnetic disc inside may have deteriorated, if in doubt try a different disk or clean the drive heads, also using the “Perform several track erases before write” this can also help with some deteriorated disks.

Writing protected game disks required a drive with the correct rotation speed, clean heads and a reliable disk, if you have issues changing the drive used for a different brand or trying different floppy disks can solve many issues, fully formatting the disk before writing can also increase success.

Using High Density Disks 

The Amiga standard drives are designed for DD or Double Density floppy disks, as these disk were discontinued before the HD High Density PC floppy disks its sometimes easier to find high density floppies in good condition, some sellers still sell sealed old stock boxes of high density disks, they may not be as reliable long term as standard double density but they can be used with the Drawbridge Controller if modified, you will need to tape over the HD hole with tape or a sticky label for the disk to work with the drawbridge controller.

Convert a HD floppy disk to detect as a DD

Copy floppy disk from ANY computer with your PC (USB Flux Hardware)

USB flux hardware can allow any modern PC to read and write back ANY floppy disk drive regardless of protection or format, these devices can also be used to write back download disk images in a multitude of disk image formats such as adf. ipf, hfe  and scp

These devices ignore the disk formatting structure of the specific system eg Amiga or Atari ST and read the raw magnetic flux data from the disk

This means that all data is captured along with the protection See Image below it shows a representation of the flux data from an Amiga  game – captured from a 3.5″ Double Density Floppy Disk game

Amiga Mouse Adapter


Mouse adapter’s for the commodore Amiga have been available for some time, the first adapters usually used a Microcontroller that did not contain a USB interface and relied on the mouse being PS/2 mode, many shapes and sizes of adapter were available some were very large and stuck out of the rear of the socket due to using through hole components requiring  a long circuit board.

The latest mouse adapters such as TruMouse were designed to be as small as possible and offer a high compatibility with most USB mice and even some wireless models from philips and Logitech

The TruMouse got its name as it’s a True USB adapter the dimension are just 30mm in Length and only 20mm Wide, its really tiny and fits ALL Amiga Models including the tightly spaced ports on the Amiga 600
