Disassembling code in a .dsk file?
|
| |
Hi. I wrote a game for the Apple II+ in 6502 assembly a long time ago and recently discovered that it could be downloaded off the net, bundled with another game, in a .dsk file. I can run it under the Apple2oasis emulator on Windows. I'd like to disassemble my game and reminisce about the pathetic quality of my code, etc. I'm hoping... more »

detecting DOS 3.3 vs. ProDOS from Applesoft
|
| |
I know this must be something well-known and obvious, and yet my searching didn't turn up anything. Is there some simple PEEK or something which would allow an Applesoft program to determine whether it's running under DOS 3.3 or ProDOS?

Here's how it worked:... more »

Question on Queuing Disk I/O in Interrupt-driven System
|
| |
I want to run this idea past the people in this group to see if there's any comment on it. Basically, I had the thought that since interrupts seem to screw up disk I/O on the Apple, why not have all Disk I/O go to a memory buffer to be processed all at once? Basically, the system would work like this:... more »
