65C02 and 65816 Quick References

I made some quick reference documents for the 65C02 and 65816. They are available at https://github.com/jefftranter/6502/tree/master/docs along with some other documents that are mostly relevant to the Apple 1 and Replica 1.

Let me know of any errors or improvements you'd like to see.

I ported the code to the CC65 ...

Re: Implementing SAVE and LOAD

I've got it working. Thanks again.

Is there an easy way to support a filename in the LOAD and save COMMANDs, and get access to that from my code? Right now I am prompting the user for it.

Re: Implementing SAVE and LOAD

Thanks, this will be helpful too.

I was also thinking about using ASCII format, and may pursue that, but the CFFA1 APIs don't directly support reading and writing text files, so that would take a little more effort.

Implementing SAVE and LOAD

Is anyone familiar with how to save and load EhBASIC programs? It's not clear to me what range of memory needs to be saved and restored.

I'm working on integrating the CFFA1 flash memory card with EhBASIC on Apple 1/Replica 1 systems. It's further complicated by the fact that the CFFA1 firmware ...

Enhanced 6502 BASIC for the Replica 1

I couldn't find a port of the most recent version 2.22 of Enhanced BASIC, so I spent an evening and got it running on the Replica 1. I also made a version that displays in all uppercase for Apple 1, Mimeo and Obtronix users.
Details are at my blog at http://jefftranter.blogspot.ca/2012/04/enhanced ...
