English Amiga Board - View Single Post - PTPlayer / Vertical Blank Interrupt / 060

So a bit more information:

- The VBR is getting set correctly via Supervisor() if the CPU is != 68000
- As far as I can see, all of the registers are being saved/restored (but I will be going over this again)
- If I install the vertical blank interrupt before I install the PTPlayer interrupt then the player doesn't initialise correctly and no sound is output at all.

I'll check on Gorman and continue my analysis...
