Dear Charley & John, Firstly I should have said that I have a (very old) computer that runs colorForth and the disk and video work perfectly. Having saved colorForth I also can now boot it directly. Only the 31 July version works though--none of the modified or later variants boot. What I am trying to achieve is to assemble the 'kernel' source, somehow add in the colorForth source (all that which I think available to edit from block 18 onwards) and then run this. MASM compiles and links the code to a DOS .COM file, so I then boot the computer with a DOS floppy and try running the program. I've just been trying to find out where I picked up this idea from (I've downloaded so many bits and pieces I've lost track) and I've found it was zip file of Terry Loveall's 800x600 at http://modest-proposals.com/binary/c4-800x600-p2bd-02.zip but this specific version didn't work for me.

In other words, it's a DOS program, not a native colorforth. Am I wrong? Then when and if it runs you can save it as a native colorforth floppy with SAVE. >> >> I hope that helps, >> Charley. >> >> >> >> --------------------------------------------------------------------- >> To unsubscribe, e-mail: [email protected] >> For additional commands, e-mail: [email protected] >> Main web page - http://www.colorforth.com >> >> >> > > > >
