Is there any substance to the rumor that Commodore will make custom chips for the A500 and A2000 that be able to use 1 Meg of chip ram? Where does that leave us A1000 owners? I have not been considering upgrading to the A2000, but this development could change my mind.

Really hope you can change your minds on this one, George. From my (graphicsweenie) viewpoint, the constraints of only 512K of chip ram are the single most severe limitation of my A1000. I'd like to be able to correct this misfeature without upgrading to an a2000. [For one thing, on my 19" deep computer table (really a tall, library reading table) the keyboard garage is a necessity of life.] As a particular example, with maximum rows, columns, bitplanes, dual playfield, there is almost no room left for storing hidden portions of windows, in 512K. Two meg would be a tremendous benefit. I realize you don't owe us (the initial buyers of the Amiga) a free lunch, but a little good will would go a long way. Kent, the man from xanth.

Really hope you can change your minds on this one, George... I'll bet someone could take the new chips and build a tower to stick them into an Amiga 1000. Assuming a hypothetical "Fat Agnus" pin compatible chip with 1 or 2 Megabytes of CHIP RAM potential the logic to do this is convoluted, but looks doable. You would need to plug into the current Agnus socket and run a clip or three down to the motherboard. Most of the logic on the board would be to unwind and/or selectively ignore the extra logic inside Fat Agnus. With FAST enough logic, timing margins should still be ok. (BTW: There was an obscure joke in that last sentence). The rest of the board would be an extra 512K or 1.5Meg of CHIP memory. [BTW: I know a company that would like to sell this. In fact, I've been asked to the design it. Now if only Commodore comes out with the part! :-) ] The only real problem would be getting the parts OEM from Commodore. Should not be too bad... Commodore has been getting back into OEM recently. (After shutting MOS technology off from most of the world for a few years). If the new chips will be in a Fat Agnus style package is matter of speculation from this point of view. It seems unlikely that one would go through the trouble of expanding all 25 DMA channels, and then do it by only one bit. By the time everything is shuffled to make space 2 or 4 or more bits are likely (even if all of those are not brought out of the package). Perhaps the test line will do double duty as a memory select? Nah. Now if the chips George is typing about support 32 or 64 bit wide access (that's CHIP width, not processor width), non NTSC video option, or straddle CHIP/FAST memory for a 32 address bit system wide DMA facility, *then* it's time to donate your Amiga 1000 to the local school or IBM-PC'ers anonymous chapter. |\ /| .

The idea of making a Fat Agnus to Agnus converter is a rather tricky one. I would advise anyone thinking about this to think instead about a Fat Agnus and Gary conversion. These two chips work very closely in consort with each other and it would take a lot of logic (and hacking) to make a TTL version work. Another problem is that Fat Agnus generates all of the clocks for the system. This replaces a mess of logic on the A1000. This means that all of the A1000 clock logic has to be bypassed. It would be much easier to replace ALL of the logic on the A1000 except the custom chips, the 8520's, and the 68000. It would make for a strange tower board but it might work ... If you look at an A500 you will see that there is very little other then the the chips mentioned above ... everything else has been squeezed into Fat Agnus, Gary, and the Video Hybrid (which you do not need). Finally if one wanted to make life even easier you could dump the writable control store and replace it by the ROM ...

No reason you shouldn't be able to demonstrate your design using the current Fat Agnus, problem being that most of the margins are eaten up by the fat vs. the external componentry on the A1000. Also there are real differences on who is providing the clocks and so on. Doesn't mean it can't be done, but you'd probably find it easier to redo the whole board than make a tower. -- George Robbins - now working for, uucp: {ihnp4|rutgers|allegra}!cbmvax!grr but no way officially representing arpa: out to lunch...

My inclination is to keep my A1000 and buy an ASDG Two-thousand-and-one expansion box. But if that means I will be unable to expand to the same amount of chip memory as future custom chips, then I may exchange for the A2000.

If you are at all worried about this issue go for the A2000. Nobody is giving any guarantees that a Fat Agnus-like chip *can* be used in the A1000. I still think I have enough tricks to solve the timing issues. George "Mr. A500" Robbins, expressed doubt as to the feasibility. Mr. Robbins has more electronics experience than I, and much more knowledge of the Amiga chipset. This still does not mean I won't try. There is no task I like more than the "impossible" task. (Want to see raster-line interrupts on a Vic-20? Sprites in the border on a Commodore-64? Non-Soviets on Mars? :-) In no case would the upgrade be exceptionally cheap. The chip alone would be hard to get and costly. Several hundred total by the time the board is populated with 512K. And, it is not even at the 'vapor' stage yet (Amiga Live! anyone?).

Asbestos Excuse Applique: Please remember that the people you are talking to here are generally Engineering and Technical Support personnel. We are most explictly not allowed to announce things before they are officially announced by the Sales, Marketing and Managment people. We, as lowly peons, are also warned against making statments or representations that might seem to commit Commodore to some action or otherwise interfere with the perogatives of managment to do business as they see fit. I suspect that if you work in a commercial environment, and have business related contact with the public, you might be subject to the same constraints. Now with that out of the way, I'd ask that you reread what has been said of the subject of hi-res chips and draw your own conclusions. I would also point out that Commodore is keeping the brave souls who bought the A1000 in mind by offering them and only them the special A1000 -> A2000 upgrade deal.

I rather take this as meaning, "there will probably be some things that the A2000 will be able to do that the A1000 won't". But keep in mind that there are some things that the A1000 can do that the A2000 can't!

The C64 can do things that the Amiga can not! Try to play Choplifter, Impossible mission or Fort Apocalipse on the Amiga! ;-) ;-) Seriously, why put down the C64? Just because there is ANOTHER computer on the market that can do more than the C64 does not make it a bad computer or an obsolete one.

I bought my A1000 back in December 1985 and as far as I am concerned, I have gotten my value back in enjoyment ten times over! Commodore has made a generous offer to those who would like to upgrade from the original to the new Amiga, do you expect them to say "oh, gee, you don't have the $1000?

Grrrrr. Both the A2000 version of the Genlock peripheral and the A2000 composite adapter will provide composite video. The Genlock peripheral seems like it may be approaching production status, while the Composite adapter fell through the cracks. Since I took it upon myself to do somthing about the Composite adapter, I seem to have aquired the responsibility for making it happen. All I can say at this point is that given production lead times, neither one is exactly a RSN item.

Check out the latest AmigaWorld. I saw at least two RGB-Composite adapters advertised. No idea on price. No cheap Zorro-II boxes for the A1000 yet. Pacific Peripherals has one for the A500, though, as well as their $200 Zorro-I box for the A1000.

(for sure the A500 doesn't, right?) The A1000 comes pretty close. The 86 pin edge is specified as being capable of supplying 1 Amp at 5 VDC. That's about enough for a Zorro interface and maybe a 2 meg memory card (done right), certainly not enough to power an 8 meg memory card or a hard disk drive (though it could power a hard disk controller if you used a self-powered drive). The A500 shouldn't have anything unpowered extra added to it other than a second floppy and the internal RAM card. NO EXCEPTIONS, you really don't want to fry your A500 power supply.
