When the successor to the creator of the board got ill then passed away I found the online updater code posted as shareware Īs I use this hardware in production, I took over some of the support on this product. The first attempt was to create code that was based on the user manual documentation specifications. It may be of interest for others to see two different takes on code that runs on the same hardware.
I put my obsolete AVR code on git along with some code for MIDI driver interfaces By the time I got the player to work floppy disks were obsolete. I had inherited the 8051 project, then after the company failed ported my code to AVR. I Used the specs from similar Yamaha, Rolland Yamaha. Interesting enough I just posted some code this week to git from a floppy disk based MIDI file player. I am finding this topic of interest too as I have reverse engineered a number of abandon ware project where the originators are dead or of advance age.
