Each OS update fixed many software problems, added new features, and improved the existing features. OS 3.10 was the last and best OS version for the TS-10. OS 3.10 also adds General MIDI compatibility. The TS-10 was released at OS Version 1. Version 2 added the capability to read SCSI devices when a SCSI board is installed and auto-load of sampled sounds when used in a sequence.

When updating a TS-10 to Version 3, you must make one cut, add one jumper, and move one zero ohm resistor. If you already have an OS version 3.00 or higher, you only need to remove the old OS eproms, insert the new OS eproms, and reinitialize the TS-10. Tools needed: Phillips-head screwdriver, needlenose pliers, razor knife, soldering iron, solder, and a continuity checker (meter). These OS eproms are for the "TS-10".
