Re: Tweaking DOS.SYSTEM from Extra-K to support other DOS 3.3 variants

An example of how this is not needed can be found on the Program Writer disk. Boot the disk, and it will start in ProDOS (1.1.1). Select "Switch to DOS 3.3", and lo and behold it switches to DOS 3.3! Extra-K had all the necessary tools to do this. I think it marked the first half of the disk used in the DOS 3.3 allocation tables, and the second half used in the ProDOS allocation tables. There were directories for both OSes, and DOS.SYSTEM loaded DOS 3.3 from ProDOS.

My idea would be to replace DOS.SYSTEM with a PRONTO.SYSTEM, ZDOS.SYSTEM, TDOS.SYSTEM or ESDOS.SYSTEM which would load a faster DOS.


Is the EXTRA-K disk on Asimov? or do you have a link to one of these hybrid
disks? or the ORIGINAL dos.system ?

I don't know where I got it. Asimov or Trenco most likely. If you want it, take all the spam out of my address and I'll mail you the disk image. "Program Writer" and "GPLE" are such hybrid disks. DOS.SYSTEM is on "Program Writer" as well as the ProDOS side of Extra-K. The DOS version of Extra-K is easier to find than the ProDOS version.
