Introduction

I would like to present new very usable variant of MIDIcar called MIDIcarSDX. The idea is to have MIDIcar ready to use without any external device, so I decided to add cartridge with SpartaDOSX equipped with PeBe's Player on CAR: device.

Features
By default SpartaDosX is running just after Atari power on. If you want to disable this feature (e.g. need to run SDX form other source like AVG/SUBcart) push button on MIDIcar during boot process. Working mode (SDX/noSDX) is marked as status LED.
If you want to run MPC (MIDI player) just type:

Code: Select all

CAR:

then

Code: Select all

X CMCP

or

Code: Select all

X CMCP /ADXXX

if MIDIcar wasn't detected properly (change /DXXX to valid address)
