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.

Near identical versions were available from the following brands:

Brand Exelvision (Manufacturer: Mitsumi Electric)
Model Exelmouse
Year 1986
Region France and Spain
Launch price 1150 French Francs
Package content Mouse, CRAM interface and cartridge with simple paint program (Exelpaint)
