A quick update on the progress of cc65 for the Challenger 1P since my last post. Several changes made it into the main cc65 repository (https://github.com/cc65/cc65) on GitHub. The conio library (http://cc65.github.io/doc/funcref.html#ss2.14) learned scrolling and got a kbhit implementation (http://...

"osic1p" target has landed in the main cc65 repository It was high time that the OSI machines get a decent C compiler... I just posted a message to the cc65 mailing list that my contributions for adding a new target for the OSI C1P have been accepted into the main cc65 repository on GitHub. I'm quo...

I'm reluctant to make this board too complicated as I have seen too many nice simple ideas grow to the point that they get so complicated they never see the light of day. I totally agree to keep things simple and focus on the RAM-only board for now. I hope we can all afford another more capable boa...

That looks great! I'd be definitely interested.

Do I see it correctly that this plugs into the expansion socket, and that the socket on top of your board can still be used for other expansions?

The c1p target of the cc65 compiler is now in a state where it is usable to create meaningful programs that write to the screen and read from the keyboard of the Challenger 1P. 8 kB RAM are pretty tight, and depending on what library functions are used the programs can quickly be too big. So having ...

I will change the object converter to use CR in...

Mike, Here is the make lib file and resultant output: ... Anyone ?? no special build scripts should be necessary. This is a walk-through how to build the compiler, the run time library and finally the hello world test program on Windows: Requirements: - Microsoft Visual Studio Community Edition 2013...

Hello Mike, Stephan, I had tried following the custom target creation docs on cc65.org having installed cc65 and generated a hello word program that runs ok on Vice for C64. Will compiling the library for the CIP from your sources not work? I have used a modified makesim file after reading 6502.org ...

Hello Mike, srecord is here: http://srecord.sourceforge.net/ thanks for the pointer, I will try srecord, and if it works as expected I will throw out the self-written object file converter. My recent purchase of an Atari 800XL had got me interested in this. Is c1p.h ; c1p.cfg and libsrc c1p and src ...

Also, the srecord utility may be useful for converting a standard output format, or a binary file, to the OSI monitor load format. I was not aware of the srecord utility, so I wrote my own converter from the cc65 output format to a format loadable by the OSI monitor. Where is the srecord utlity ava...
