Here is a ZIP file containing the SIM and BOOT for my 40KB C1P. It works with my D&N expansion board (RAM and floppy I0) and probably would need to be modified for different expansion hardware including memory size. It also assumes use of my MONITOR ROM.

Mike or anyone else can post the images they have or create - not a problem. My goal is to able to generate the images so I can easily distribute the last OSI released baseline and then distribute updates. It is probably worthwhile for me to discuss the nature of the updates since the last OSI relea...

In the midst of checking the versions of the files for the C1P release it looks like I have developed a bad drive B. I have a spare 40T SS drive that I will try to swap with that drive. Once that swap happens then I will have to verify that the "new" drive is working correctly. It will take a few da...

Attached is a .zip file with the source code for the five inch drive utilities included with the OSI release. The V2.01 files are minor changed versions that can be assembled without change using the shareware or licensed version of TASM. Note that for all ongoing development and maintenance I use e...

The attached .zip file has the DOS/65 source code for the C1 MONITOR ROM that will directly boot DOS/65 and the source code for the 5 inch format routine.

DOS/65 is freely distributable for non-commercial use. I do ask that the lineage of the code be documented in the source files.

Thanks,

Rich

I tried to send the source code for C1 monitor ROM that makes DOS/65 easy to start up as a file attachment. The forum software would not accept either ASM or TXT as a filename extension.

What is accepted?

Very good!

I just wrote a long reply and when I tried to submit it the system asked me to log in again. When I did I lost the post.

Past my bedtime - I will redo it another day.

My C1P uses the RUB OUT key but SHIFT-O is working for WinOSI.

Thanks!
