Now that the new Agnus chip is out, I assume that the CATS are allowed to talk about it. I'd like to know all of the new features of it, as well as which ones we will have to wait till 1.4 to use. It seems definate that the new chip can handle 1 Meg of chip ram, but can it handle 2 Megs? (2 Megs is the address space set asside in the Amigas memory map for chip ram.) Is this the chip which will handle the roumered non-interlaced display? Is there any truth to the roumer about it having 64 color registers? Douglas Peale

I wonder what does it require to update old
A500 to use new Agnus ( and 1Meg chip ram).
Is that possible, and what should be done?

The A1000 depends on a lot of external circuitry to handle bus arbitration and the things that need to be done to direct certain memory reads to CHIP ram and others to FAST ram. On the B2000/A500 all that stuff is done by Agnes (that's why she's put on weight). This means that the external pins to Agnes are completely different than the pins on a Fat Agnes or Fatter Agnes. Even if you added one additional address line to your A1000 and if you could* ignore all the other lines BUT correct the timing on the similar lines; it still wouldn't work. The only way to get a working Fatter Agnes is to sell your A1000 and buy an B2000 or A500. -Tom * -- You can't. -- Tom Limoncelli -- tlimonce@drunivac.Bitnet -- limonce@pilot.njin.net Drew University -- Box 1060, Madison, NJ -- 201-408-5389 Standard Disclaimer: I am not the mouth-piece of Drew University

Actually, you don't need to sell your 1000; a new 500 or 2000 will operate correctly even if you still own a 1000 (like I do). Which reminds me -- I finally had resaon to use the PCCopy (and PcC720 program to patch PCCopy to read a 3.5" 720K disk). First of all, I think it's time that PCCopy would know how to do this sort of ting on it's own -- I'm mean, it seems so silly that this program can only be used for 5.25" drives. Anyway, I tried it on my 2000 and zilch -- it couldn't recognize anything on the disk. So I tried it on my 1000 and it worked! What's the deal here? Is there something wrong with PCCopy or PcC720, or is there some incompatibility with the type of drive I have in my 2000? Please post definitive responses: I imagine this info would be helpful to others who stumble upon the need to copy data from 720K PC floppies. Flip side, joe piazza --- "Where's my other sock?" A.

Hello All! I've got an Amiga 2000 with a multiscanning monitor. And I've already placed an order for the new Agnus chip from my dealer. My question is: Will the new chip do me any good right now? Other than the ability to multitask more chip RAM hungry applications, what other functions can it serve before 1.4? Will I be able to use any of the newer non-interlace modes with existing ROM/OS/software?

Someone (Ed ?) save this and put it in the intro posting : Walk up to an Amiga. Open a CLI window and type : 1> Avail it prints out a table labled : Type Available In-Use Maximum Largest chip XXXXXXX fast total Check the number where the XXXXXX is above, if it is 523232 then you have the original agnus, if it is significantly more than this (like 1048576) then you have a new agnus. Other ways to use this information : If you plunk down $100 to get the new agnus and when you pick up your machine it fails the "Avail test" then you know the dealer botched the installation. If your machine passes the avail test but has garbage on the screen, or weird arrangements of screen bits. Then either the dealer botched the installation or you don't really have a new agnus or you are running a Schwab screen hack. If your machine crashes a lot especially when you have several full size CLI windows open then you know the install was botched. --Chuck McManis uucp: {anywhere}!sun!cmcmanis BIX: cmcmanis ARPAnet: cmcmanis@sun.com These opinions are my own and no one elses, but you knew that didn't you.

I think the original question was how to detect the presence of an "uninstalled" New Agnus. Obviously, if the New Agnus is properly installed then you will boot with more than 512K of CHIP ram. But what if the new agnus is in a machine that originally had the old agnus in it but had the old agnus pulled and the new agnus inserted without any other changes? How does one detect that? -- Darren

There is another location which will give you the "Denise Version" value. I don't have the docs right with me, or I would post those custom chip register addresses. At any rate, it should be a simple program to write, which would inspect these locations and report the Agnus and Denise versions installed.

My point is that you cannot find out whether the new Agnes is there or not just by typing AVAIL, when all you got is 512K of RAM. Now even if you add the expansion module to the A500, the AVAIL will not show 1M chip RAM. You have to reset some internal switch to make use of extra chip RAM. * You cannot tell the presence of new Agnes in A500 without opening the unit, unless the documentation says so. * Tomi

The board has jumpers to select the PAL or NTSC mode at powerup, inform the agnus chip to use the extra 512 k, and change the memory from $C00000 to $080000. -- ---------- Lawrence W.

Using SI, I'm told I have a Super Agnus. But my 512K of chip memory, as well as the dealer I bought the 2000 from not long ago, tell me I don't. My motherboard's a 4.5 (bought the last 2000 they had at WOC Valley Forge...), and I don't think the 4.5's ever shipped w/a super agnus.

And it doesn't work for me on my old(?) A1000. It says I have a PAL Agnus. Fat chance! I bought this bugger way back, well, 4-years ago today I do believe, and I don't believe that CBM had PAL chips ready then! As for the `Normal Denise Chip' I couldn't find the offset that Jeff used to determine that boolean (normal or new Denise chip). Manx's SDB says that DFF004h (the mem location for the Agnus chip test PAL/NTSC/etc) reads 8000h.

this will now work b'cause there must be a mod to the mother board with a 501 Expansion Card to get 1 meg of CHIP Ram. The unfortunate side affect is that the 500 after the mod will not work WITHOUT the expansion card.... ( this info was gleaned from the latest issue of Amiga World ) adam hill

You really should have looked at the source code - it takes only 2 minutes.
Actually, the last line should be "graphics.library is -Unaware- of the
presence of the 1-meg Agnus Chip". Remember, there is a lot more to the
new Agnus than just accessing more chip ram. For instance, it is no
longer limited to 1024x1024 pixel blits. The new Agnus can do a 32Kx32K
blit, but you need a newer graphics.library to take advantage of that.

Excuse me but you did say 32Kx32K for a blit op no? How is this so, I mean why is such a large blit capacity offerred? Am I correct in my interpretation that 1 Giga pixels may be operated on by the blitter at one time? How is this abil- ity expected to be used? My my, these are only questions here...and nary a byte added to the signal of this discussion. My apologies to all but I really do not understand what the new Agnus chip will be capable of doing with this feature. yours truly, Lou Cavallo (alias Anjin_San) Gratuitous Paul Hoganism: "Toss another Mac on the barbie will ya..."

Also the fact that it listed my Denise chip as not being the new version makes me decide to pass on this utility.

OK, 1 Giga pixels would be too much for use on a display, but when you try too render for high resolution devices (i.e. photo typesetting) you get up to 10k x 10k pixels on a page. And even a usual laser printer with 300 dpi offers 3k x 4k pixels. That exceeds the limits of the old Agnus. Thanks those who wrote the printer.device, it can handle large bitplanes. Now (with a new graphics.library) we can easily render it using system code and blitter speed. Unfortunately, I don't think that we can emulate these capabilities with the older Agnus.

Using this scheme it will be possible to scroll screens without any noticeable colour separation, and without duplicate buffering the screen. (Magical isn't it? Of course the font library will have to be updated to support modulo 4096 lines, and to find horizontally separated bitplanes correctly...) My question for 1.4? Has this already been implemented for the default boot screen? If not, will it be supported in any manner for 1.4? -ss
