Re: Need 3.5" ProDOS Bootables for //c+



Roy:
I did say 'for the most part'. I have several utilities that allow the use of larger media for DOS 3.3. Natively the DOS handles up to a 400k volume, but most programs that run off of 5.35" diskettes do not support that model. Way too many commercial programs require track sector access and do not use the DOS calls to handle files.

Take The Print Shop as the best/worse example. It manually reads track 11, sectors F through 1 when cataloging a disk. If it did what it was supposed to, one could list a larger volume with all those graphic files. Technically it does load files properly so you can use an extended catalog to store extra files, but it will only list the files in the 'normal' 5.25" disk catalog sectors. (Of course there is a patch in a back issue of Computist to fix this too.) On top of that, The Print Shop's DOS has not been patched to recognize anything other than 5.25" disks. Which is really too bad. I once tried to move the program to a different disk and the program could not run. :( (I'd still like PS on a 3.5" diskette with all those graphics.)

But I digress.
