Stumbling blocks...
Today, with only a precious few moments available for RC stuff, I came across two potentially devastating problems with the album-on-a-floppy project.
The first, which I touched on earlier, is that my sequencer program appears to be trampling on reserved memory somewhere. I had assumed it was in the zero-page, but after bashing my head against it for an hour I'm completely at a loss... I can play each song once after booting the system, but subsequent attempts result in unwanted behaviour. This is going to be less fun than I'd hoped!
The next major tragedy is that my big idea to use DOS 3.3 as opposed to ProDOS in hopes of freeing up more disk space is looking somewhat ill-advised. Unless I've royally buggered something up, it appears that DOS 3.3 uses 6 blocks (1536 bytes) to store a 1024 byte file, which is exactly 50% more than I had assumed... oh, the humanity!
