Apple II EuroPlus

I'd like some help diagnosing an Apple II EuroPlus that i've been given, i've recapped the power supply as several capacitors had burst, so that side of it is fine, but upon booting i'm greeted by garbled graphics: Link to video  Please excuse the screen refresh!

 

Any help will be greatly appreciated.

cc65: crashes loading to $0800 on ProDOS system prg.

Hi!  I am working on a version of MadLib for AuxMemApple.  It is a ProDOS system program.  I load some code to the unused space between $0800 and $1000.  Excuting this code seems to crash the system: I get the monitor at location $A504.  I can just store this code in the main module, but I like using extra unused system memory via my Cubbyhole optimization technique.  :)  When I check the size of the data loaded to this memory, I get the number 65088.   I'm using ProDOSi to load the data.  I attached the config file and the code that loads the data.

Does Mapping the Apple 2 exist?

Hi!  I have the etexts of several of Compute!'s Mapping series.  They were pretty useful.  However, I just Googled the Apple 2 version and didn't find it.  :(  Does it exist?  If so, where can I find it?  If not, where can I find a memory map for the Apple 2 series?

AuxMemApple near completion

Hi!  I am working on my AuxMemApple library for the Apple2/cc65.  It is a memory extender that allows the usage of aux memory from cc65 programs.  I believe it's better than cc65's em libraries because it provides a way to access any byte or word in aux memory and string and memory functions that mirror the standard memory and string functions.  The library works so far.  Right now, I need to provide a way to reconnect the RAM drive at the end of the program, some demo programs and to write the manual.  Then, the first beta should be ready to upload.

If yes is there a documentation of the commands to use?

cc65 users: Apple ProDOSi

Hi!  I have ready an interface for cc65 that provides access to ProDOS's functionality.  It is much more efficient than the standard C library's file I/O functions.  You can find it at c65 additions - Manage /util at SourceForge.net.  Try it out!

cc65/ProDOS test program giving me monitor

Hi!  I am working on my ProDOSi interface to cc65, and the test program is giving me the ML monitor.  I think the problem is before the main() function because the first line in the main() function writes text to the screen, and the text is not being displayed.  I am not using a custom crt0.s file but am using a custom cfg file.  I attached the cfg and build batch files.

IIgs doesn't recognize 3.5" floppy drive or FloppyEmu

Hello!  I have an issue that cropped up the other day that is perplexing me.  I had been downloading cool demos from Ninjaforce to play on my Apple IIGS.  It's a Rom1 running a Microdrive Turbo for GS/OS, 4mb GGlabs RAM, and Darksound sound card.  I was booting directly from my FloppyEmu into the demos.  Yesterday I tried to set things up again and the computer wouldn't find the FloppyEmu.   I got "No device connected."  I tried and I tried and nothing.  I disconnected everything, removed the cards, and reset everything to default and still nothing.  However, last night I was able to get a

cc65/ProDOSi/Text Adventure file buffer issue

Hi!  I have cc65 and am working on ProDOSi and thinking about porting some text adventure skeleton code to the Apple2.  I want to have the last be a system program and use the space between $0800 and $2000 for extra code and data and I/O buffers.  I only need two (or maybe one) files to be open at a time.  How do I use ProDOS to set the buffers?  ProDOSi so far can open and close files, and I'm currently working on read/write access.
