In the July issue of Electronic Musician, Scott Nichol gives a very good explanation of why the hard disk tends to hang when using the MPU-401. He describes a method of using getvect() and setvect() to alleviate the problem. However, I am still clueless as to how to actually implement his solution. If anyone knows, PLEASE enlighten me. It is a very frustrating problem. Thanks, Wayne Simmons

It is a very frustrating problem. The easiest thing for you to do is to simply buy a toolkit that contains working ISRs. The Music QUest toolikt comes with a refererence for the MPU plus 3 disks of code which includes a working ISR. Then all you would have to do is link it in. -- Gene De Lisa "Ducking for apples--change one letter and it's the story of my life" Dorothy Parker(1893-1967) (spoken at a halloween party)

did you ever try rewiring the IRQ on the MPU board? all you have to do is get the MPU away from the line that the disk shadows (2/9, i think). works for me.
