Hi 
can this drum machine be restored to working order?

Due to many years in storage the factory-programmed logic array chip has lost its memory. This is according to a service engineer I took it to a few years ago. 

There is also an EPROM in circuit with the OS in it, which works as it should. I have re-programmed this with two versions of the OS to no avail. 

The RAM chip still contains the pattern and settings data. 
I know this because switching on the machine and pressing play, I can hear the clicking of the 'Accent' part. 

Any help greatly appreciated

Move to quarantaine

This moves the raw source file on disk only. The archive index is not changed automatically, so you still need to run a manual refresh afterward.
