No! Can you make them both work?
I find that I need to mount the /sd0 and be able to access a normal dsk
image in the second drive.
I copy things from /d1 to /sd0.
Or am I doing this wrong?
I want to eventually copy the files off my standard MultiVue 40 track
DSK to the /SD0. Or does this use /SD1?
If your planning an update, how about the ability to set a startup video
mode and colorset (Width 80/40)?
What about an AUTOEXEC feature on startup (run a predefined program on
start).
And if you're really game... add a command switch between 225 and 192
scanlines (40/80x27 text, 320/640x225 graphics).
(See what happens when you give me an inch? I take a mile!)
