Hello again,
Would you please explain to me, can I use every SCSI controller
with Amiga (500) ? (It's probably no). Which port of Amiga used
by the controllers ? Can you tell me cheap and fast controller
brands, models and price ($) which is you are using without problem
or you know well. I realy don't want to buy Commodore's A590.
There is a lot of SCSI controllers but all of them for PCs.
I have to ask brands and price because I'm not in USA but I think
to buy from the USA. Would you like to help to me please...

Hello everyone! Sorry to bother everyone out there this close to Christmas, but I need to know the answer to this problem very quickly! You see, I have A 1080 monitor which still works great (I bought it in 1986), but I'm going to be putting together an IBM clone for my mother (she needs it for all those IBM-businessy things) and I was wondering if the PC could use the 1080 as an EGA compatible monitor. If this is possible, then are there any restrictions, such as having to use a 400 line EGA mode in interlace, or even the 350 line mode? What can and can't be done? Also, what would the black switch in the back be set to? TTL Pos, Neg, Analog RGB, ??? And lastly, what would be a good EGA card to get if this works? Any E-mailed comments regarding this matter and would be welcomed and greatly appreciated at the above address. =//==================================//==============================//======== VX I-Net: psherman@acsu.buffalo.edu VX Standard disclaimer applies.

Hi, I am a freshman at Case Western Reserve University. I wish to expand my A500 with a couple of megs of RAM. The expansion port on the bottom already has a A501 so I would like to have another 2 to 4 megs as cheaply and easily as possible. I have read about boards from Spirit Technologies, etc. that hook right up to the motherboard. Which one do you think is for me? Where is the cheapest mail order place? Please email your responce to me--- I would greatly appreciate it!!!!!!!!! J.Norell Guttman Email Adress:njg2@po.cwru.edu

HELP! I'm trying to do a little program in assembly that sets up a viewport and displays it. However, I can't seem to restore the original Workbench display. I know this: I must call LoadView() while passing a pointer to the View Structure in a1. However, I can't seem to find the original View Structure. My manual says to find it in the offset ActiView in the GfxBase structure. My book says the offset is 2. I don't believe it. It looks wrong, the the program immediately Gurus, with no Guru number, because the display is frozen. Anyone who could shed some light on this would have my infinite gratitude, and many profuse thanks! rudolpe@jacobs.cs.orst.edu

It looks wrong, the the program immediately >Gurus, with no Guru number, because the display is frozen. According to "Amiga ROM Kernel Reference Manual: Includes & Autodocs (revised and updated)", i.e., the book that contains listings of all the standard include files provided by Commodore, struct GfxBase is as follows: [p D-38] struct GfxBase { struct Library LibNode; struct View *ActiView; ... That is, the pointer to the active view cannot be in the offset 2 for the first *member* in the structure is a structure, the size of which is 34 bytes. The second element in GfxBase is a pointer to a View. In other words, the view pointer is in the offset 34, calculated from the beginning of the GfxBase structure. You seem to be using assembly language, and this C'ish explanation is not perhaps a very clarifying one, but I hope this helps. When I had a problem of the same sort, I solved it using either RemakeDisplay() or WBenchToFron() [can't remember it off hand, sorry]. BTW, if you are programming the WB environment, I recommend using some high-level language, like C or C++. It can save you a lot of hair :-). >Anyone who could shed some light on this would have my infinite gratitude, and >many profuse thanks! >rudolpe@jacobs.cs.orst.edu -- Risto Kaivola (dix@clinet.fi) or (Risto.Kaivola@f123.n220.z2.FIDONET.ORG)

Correct. >However, I can't seem to find the original View Structure. My manual says to >find it in the offset ActiView in the GfxBase structure. My book says the >offset is 2. I don't believe it. It's wrong. The offset is 34 ($22). ActiView is the second structure member in GfxBase, though. >It looks wrong, the the program immediately >Gurus, with no Guru number, because the display is frozen. Using an offset of 2, you are trying to LoadView() some data from the graphic's library node. This must fail. :-) >rudolpe@jacobs.cs.orst.edu -- Best regards, Franz-Josef Reichert VOICE: +49 6805 7417 Kuchlingerstrasse 13 UUCP: ...uunet!cbmvax!cbmehq!cbmger!kbsaar!fjrei D-6601 Kleinblittersdorf GERMANY
