HA!!1 great find.

I recall asking about how to realize this just 3 month ago. And now we have a point to start from.

Thanks for sharing!!!! I remember there is another video about Dave’s full KIM-1 system in his channel.

I was curious and tried this out, it works fine! I'm not sure how much I can leverage this with my unexpanded PAL.

A Simple C Hello World Program yields around 2.3K.

Instructions to anyone who wants to try it out,

git clone https://github.com/davepl/cc65
make all
cd samples/kim1/
make
srec_cat kimHello.bin -binary -offset 0x0200 -o helloc.ptp -MOS_Technologies -CRLF

Nice addition.

Character I/O looks good, getch does not echo since the hardware already does that.

I wonder if he tested the tape routines, he treats those as subroutines, which they are not..
