Sorry to bother the net for this, but... could a reliable source at Commodore (best would be Dave Haynie) give a final statement here on the net about the New 1MB Agnus working in older (pre-rev.6) B2000s? At Commodore - The Netherlands, they told a friend it couldn't be done. If I get this posting, I will send it over to them, and call back often. If they (known to be lazy) keep on saying "no", I will write a letter to a Dutch Amiga-magazine. The New Agnus chips are available through a few dealers. On the net, some guys said they simply replaced them, but this is too dangerous to try on my own. Technical info: I have a B2000 rev. 4.4, A2058 (2MB) rev.4 and A2088 rev.3 PLEASE give some reaction, otherwise lots of Dutch B2000 owners will be left stuck with 512kB CHIP RAM. This will give the same effect that had A -> B, people hasitating to invest now ('What will happen when rev.7 comes out?'). or wait for the 2MB Agnus.

I have in my office alone, three Amiga B2000's, one withch of the following Revs, 3.9 (original DealerKit), 4.2, 4.3, and at home two others 4.4 and 4.6. As to the usage of the New Fat or Super Agnus (whichever you prefer) working in these rev motherboards you should have no fear, all the ones I just mentioned were upgreded by me with absolutely no problems at all. I tnink this should answer the question once and for all. -- ******* Rick Unland Commodore Business Machines **************************** * Usenet: uunet!cbmvax!unland ARPA: cbmvax!unland!@uunet.UU.NET * * Standard Disclaimer: If I said it, I was drunk! * * If I didn't say it, I wasn't drunk enough! * * "I thought they said the Commodore could stand up to anything!" * *********************************************** Earth Girls Are Easy! **********

Although I'm not Dave I'll respond anyway, I did the upgrade (rev 4.3 B2000) myself and no problems occured after this. We've tested on the following configurations: B2000 rev 4.3 > rev 6, AT/XT bridge boards, GVP equipment, A2620 and several other expansion boards and there was NOT A SINGLE problem to overcome. Everything works OK, as long as you cut the right trace(s) (1 extra for PAL Amiga's). >At Commodore - The Netherlands, they told a friend it couldn't be done. He probaly called the info-line, thats not the right place to ask since its meant for simple problems like printers etc. Besides that they can't tell you to hack up your equipment which can do some real damage if you do it the wrong way. I wonder who you're going to blame when you messed up. As far as I know the new (SUPER/OBESE/FAT*2) agnus will be only availble as a spare part through your dealer, if he sells it as an upgrade you're lucky but C= is not offering the thing as upgrade right now. > [ ... ] Writing to one of the Amiga magazines will not help you, write (or call) to the task-force Amiga manager and tell him your problem (this is for all you Dutch guys out there) concerning support and I'm sure he will help you out or at least give you a straight answer. There's a whole Amiga task-force team sitting there right now to *solve* all problems. I know I'll get flamed for this by some brothers, send e-mail. -michel hp4nl!neabbs!amichel@uunet.uu.net | Just speaking for myself. reality is for those who can't afford drugs

The 1 Meg Agnus works in all B2000s. There are two or three jumpers to change to install it correctly (J101 is moved, J500 is removed or cut depending on how your board was assembled, and J102 is cut if you want to come up PAL instead of NTSC). The Rev 6 board _requires_ the 1 Meg Agnus for support of refresh on it's 256K x 4 DRAMs, but it will work in every revision of the B2000 ever shipped. It will not work on the original A2000, which may be available in the Netherlands as well as other parts of Europe. The easiest way to identify the type of motherboard in your system is to see how many RCA phono jacks you have in the back of the machine: there are 2 on the "A" board, 3 on the "B" board. > | # # # # | Marco Niese | //// | -- Dave Haynie Commodore-Amiga (Systems Engineering) "The Crew That Never Rests" {uunet|pyramid|rutgers}!cbmvax!daveh PLINK: D-DAVE H BIX: hazy Be careful what you wish for -- you just might get it

Network Comment: to #1369 by unland@cbmvax.UUCP You talk about the "Fat Agnus" or "Super Agnus". Here in NJ, alot of talk about the new Agnus uses a different name. Since the older 512k Agnus was called the Fat Agnus, we here call the new Agnus it's most logical derivative of "Obese Agnus". --Bob _________________________ Pro-Graphics 201/469-0049 __________________________ UUCP: crash!pro-graphics!bobl | ProLine: bobl@pro-graphics InterNet: crash!bobl@pro-graphics.cts.com | CServe: 70347,2344 ARPA/DDN: crash!pro-graphics!bobl@nosc.mil | AppleLink: Graphics3D ___________ ____________ Raven Enterprises - 25 Raven Ave. Piscataway, NJ 08854

But then, you're from North Jersey; I live down South in the swamp. Actually, the term "Obese Agnus" is probably the least accurate. The original 512K Chip RAM Agnus that manages 1 meg total, as found in all A500s and A2000s initially, was called Fat Agnus because it was basically the original 48 pin Agnus from the A1000 with a mess of glue logic all sucked into an 84 pin package, thus making it a "Fat" Agnus. To call it Obese is really incorrect, since it's not "fatter" by the original definition of "fat" than the original Fat Agnus. I think Commodore likes to call it Super Agnus, but I think that's just because, for some reason, the word "Super" is in vogue among the chip people here these days. I always call it "1-meg Agnus" because that's the most functional description, though I thought "Gordo Agnus" was kind of funny. > --Bob -- Dave Haynie Commodore-Amiga (Systems Engineering) "The Crew That Never Rests" {uunet|pyramid|rutgers}!cbmvax!daveh PLINK: D-DAVE H BIX: hazy Be careful what you wish for -- you just might get it
