Photoshop 1.0 sourcecode in Pascal.
« on: June 17, 2023, 04:04:12 pm »
Hi I have just found information on Photoshop 1.0. Its source code was publish in here https://computerhistory.org/blog/adobe-photoshop-source-code/ and on github https://github.com/amix/photoshop.

That first version of Photoshop was written primarily in Pascal for the Apple Macintosh, with some machine language for the underlying Motorola 68000 microprocessor.

I think its worth to check it out.

Looks interesting. Brings back memories of the Motorola 68xxxx code.  :D

minus the ASM code, I think I could convert that over to laz within a short time.

It looks like the ASM addresses screen operations which should be easily conveyed over to pascal code that already does  it.
