Apple Pascal on IIGS

Has anyone successfully used Apple Pascal on a IIGS? I have a ROM 01 IIGS with two 3.5 drives and one 5.25 drive. I thought I would be able to find a 800K disk image of Apple Pascal 1.3 somewhere, but I was unsuccessful. I have also tried to use Floopy EMU as a second 5.25 drive. I have tried Apple Pascal 1 disk in the real 5.25 drive and Apple Pascal 2 disk in the Floppy EMU and the Apple Pascal 1 disk seems to boot okay, but the Floppy EMU blinks a few times, but all that is on the screen is a square character in the upper left corner of the screen. I'd appreciate any suggestions on how to get Apple Pascal running on the IIGS.

Do you want to create an

Do you want to create an Apple Pascal volume, or do yo simply want a good version of Pascal for the //gs?


Volumes under Apple Pascal 1.x are noteworthy for requiring fully contiguous data; so, you will end up with volumes that have 600K of data on an 800K diskette, ansds yet be full, and I suppose this could create issues with some disk image formats. The only real reason to use Pascal 1.3 is if you have a selection of Pascal P-machine software, and you want to store it on a larger volume. 



For GS/OS, I suggest this:



P.S. I did find this shrinkit image, that purports to contain a patch for Pascal ProFile manager that will allow using 3.5 drives and SCSi drives:




ShrinkIt archive of a disk containing Pascal ProFile Manager patched so that PPM will work with 3.5 inch drives and drives connected to Apple SCSI cards.

I did use Apple Pascal on 2GS

I did use Apple Pascal on a ][+ and then on my IIGS later, worked fine once I made a 3.5" disk with everything on it.

Look here for an image that someone made one like it:

 Apple Pascal 1.3 3.5.po

Works fine in gsplus.

I forgot what a pain navigation was!  So much typing!  I wrote some early polygon scale/rotate/hash code (made nice fanfold banners)

 I moved to Macintosh Pascal and then on to Think C...
