Hi all,
I noticed that the SB-55 has a test mode, whereupon if you put the unit into standby mode and press and hold the PROG+SET+RWD+FF buttons, you see 'tSt' appear on the display. According to the manual you should see SEr on the display for service mode - it seems that the service mode requires a specific diskette that wasn't mentioned in the service notes.
It turns out, in this mode, the SB-55 will load program code from the disk and execute it. It has a NEC V25 CPU which is 8086 compatible too.
With this in mind, I created a cool little demo - a game of snake for the SB-55 and SoundCanvas. Currently a remote control is also required to control the game.
Write the attached image to a disk, put the device into tSt mode, and insert it.
Controls are as follows:
Play - start game
Stop - pause game
Song down - left
Song up - right
Tempo up - up
FF - down
I'll eventually add controls via the front panel controls so that a remote control won't be required and polish this a bit more.
Video of it in action is here: https://www.youtube.com/watch?v=uAvGC3Sdd4M
EDIT: Version 2 added - adds front panel controls, a sound effect when the apple is eaten, front panel LEDs are now used, and also the ability to reboot the device by pressing the power button.
