is it possible to program the IIGS specific graphic modes with APPLESOFT Basic?

(or any other Basic)

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.

Apple ][/II+/IIe I/O Controller aka Apple ][ 5.25" Disk Controller - info needed

So there is no confusion, the Apple part number for this controller is 655-0101-B that I recently purchased to be used with a recently purchased DuoDisk and hopefully the Floppy EMU hack drive.  I have no cable for the DuoDisk but can make one or buy one.

(IIgs) SS RAM-GS expansion chips

Hey all -

 

I've recently started to get back into my IIgs and that includes opening them up and re-aquainting myself with what's installed.

 

My ROM 3 GS has a RAM expansion from Sequential Systems, (c) 1991, one of the cards without the RAM-GS silkscreening.  It's a 2MB card with the open row of sockets available for expansion.
