Question about minimig,VGA, and NTSC
« on: December 07, 2011, 05:29:50 AM »
Hello all Amiga enthusiasts,
 Sorry if this not appropriate forum for this question, but did not see forum one that looked more appropriate. Anyway, by way of introduction, I will just say that I owned an Amiga 500 back in the late 80s and early 90s. I enjoyed it very much, especially the Falcon F16 Flight Simulation by Spectrum Holobyte. I had to sell the system about 92 to pay the rent.
Have since then been working with Intel/Windows systems.  Just happened to stumble on info about minimig systems that reproduce Amiga chipset in FPGA. Very interested in getting one but have a basic question.   From my reading , I see that minimig has VGA .  I don't really understand how that works in regard wanting to be able to run software designed for NTSC. I read something about NTSC and PAL cores but again, not sure what that has to do with VGA. Could someone please elaborate on this question. Thanks in advance.
                                                  Paul L
P.S. I still have my Falcon disks and a couple other Amiga games and would like to run them if possible. Thanks again.

Thanks to all who replied to my question. I feel better about the chances of the minimig board being able to provide a NTSC signal via the VGA output. I would like to ask a follow up question and hope at least one of you will go the extra step to answer it.
I am now just trying to picture how the selection between NTSC and PAL is done. I am wondering if I would need to desolder a crytal set for PAL timing and solder one set for NTSC. Also I am trying to figure out about cores. Are cores just another name for a kernal like in Linux ?
I have tried to find these answers by just surfing various forums and such but am still a bit hazy on what needs to be done to get a board ordered from someone like AmigaKit up and running. Thanks again and I appreciate your time and consideration

Again thanks to Matt_H, Darrin, bloodine, and FaLLeNOnE for your responses. Your responses have been very helpful. I am determined to get a minimig system ( with 4 MB). I know that it is not for sure that it will be able to run all the software I still have from 80s/90s although I did see that there is at least one config that will run Falcon F16. It may be a month or 2 before I can get one, but when I do I will check back in with news. Thanks again and any additional advice regarding configuration info ( just a link or anything) will be appreciated.

Many thanks to mikej, Darrin, and Dwyloc for your interest and efforts concerning the feasability of being able to run the software I mentioned. The system I have in mind is the minimig v1.1 so that is promising that you ( Darrin ) were able to get the ADF image file to run ( which I suspect would mean that it is also feasible that the original disks would run)
 In any event, my determination to get back into Amiga systems is not wholly motivated by being to run any one particular progam. I am also just interested by the FPGA aspect of this scene. In fact, i recently purchased an Altera Cyclone2 DE1 Development board and registered to use the web version of that CAD software used to program the board. I have tinkered with it just a bit so far , but am very interested by the possibilities. Of course,  I know you guys and/or gals all realize that the minimig and NatAmi are realizations of these possibilities.
 So anyway thanks again and I will be posting again ( maybe in the forum having to do with hardware/software as well as this one) Thanks again.
