ASM / Re: [680x0 ASM] Get Amiga Config

« on: March 13, 2010 »

Since this thread was brought to my attention today I just want to make clear that I had my reasons to react like I did and va!n surely knows them! However, if I wanted the code to be deleted I would have said so. So feel free to use the code in whichever way you like, I do not mind, after all it might be useful for someone. No hard feelings or anything.

Cheers, Sting

ASM / Re: [680x0 ASM] Get Amiga Config

Interesting what one can find while browsing forums at work...
Let's compare it with the routine I've coded for my demo-system:

Code: [Select]

*******************************************
*** Get Configuration _GC ***
*******************************************

; determines output in
; - ChipSet OCS/ECS/AGA d0
; - Kickstart version/VideoFreq d1
; - CPU version (e.g. "$68000") d2
; - FPU version (e.g. "$68882") d3
; - Free ram (Chip) d4
; - Free ram (Fast) d5
; - Max ram (Chip) d6
; - Max ram (Fast) d7
; - Amiga type (real/emulator) a0 -1=emulator, 0=real

; kills: d0-d7/a6

Déjà vu or what? So dear va!n, even if it's "old stuff from your group" (which I once was member of) I can't remember that I ever allowed you to publish my code... Specially in the way you did it here without mentioning who actually coded it. Apparently some things never change...
