Description

The Exelvision Exelmouse[1] was a rebranded Neos MS-10 offered as a peripheral for the Exelvision EXL-100 computer[2].

It came bundled with a paint software and a "CRAM" adapter with by-pass connector (to allow a memory extension and/or a floppy controller at the same time), provided with a MSX compatible DB-9 connector.

It was not directly software compatible with the Exelvision system, games or BASIC, so it needed to be accessed by machine code. The TMS7020 source code to read the mouse is available on the [1]link above.
