List of projects / Sum USB adapter

Sum adapter enables connecting USB HID keyboards to your Amiga. It has been designed for installation inside A1200’s casing. Sum is based upon 16-bit Microchip microcontroller.

Sum provides built-in USB stack which enables USB HID keyboards support without the need for installing additional AmigaOS software drivers. Device’s installation procedure consists of simply attaching it the U7 chip located on A1200’s motherboard.

Additional feature of the adapter is its „Bootloader” function allowing future firmware upgrades.
Sum comes with dedicated configuration mode, which becomes available when one presses simultaneusly R-Shift + Pause keys. User preferences are saved to the built-in EEPROM memory – thanks to which when you reconnect the device – it is already configured!
