Hello. I'm looking to buy the A1000 or the A500 and cannot decide which. I had an Amiga 1000 as a kid, and like it for the nostalgia, but aside from the collectors standpoint, I'd like it to be functional as well. I know some will recommend the A1200, but I'm set on the latter two models.
Are there any major differences aside from the OS Kickstart being on the A500's board and the increase in RAM? I'm assuming that I can always upgrade the A1000 RAM if needed.
Any comments/suggestions would be appreciated!
Thanks!

I think you'll find more practical use in an A500. The ROM based kickstart means you can upgrade it to OS 3.1, and even OS3.9 if you can find an accelerator. It also can use a 1MB Agnus chip, which, in addition to providing more Chip RAM, allows to to display both PAL and NTSC screenmodes - important for compatability with the widest range of software. It can even be brought up to the 2MB Agnus chip with the approprite upgrade (fairly pricey, but still somewhat available).
Expansions for both of these machines are pretty rare these days, so it may be a while before you can get it up to the spec you want. Good luck, and enjoy!
-
Hi!
Strictly comparing the 2 models, the A1000 is much harder to upgrade. The A500 had many more model specific hardware upgrades than the A1000 too. The expansion slot while supposedly technically compatible, are on opposite ends of the computer and upside down(?) on the A1000. Meaning, realistically you can't use most expansions from the A500 on the A1000.
IMO what is an important question is, what do you want to do with it? Both models have their strong points, but the A1000s is mainly nostalgia value and looks.
-
Design-wise the A1000 is a neat machine. Most, if not all, custom-chips on it should be replaceable by A500 versions making it as good / bad as the A500. However, it seems that for the A500 more expansions have been designed and sold. Also getting spares is easier: just buy a functional A500 for a box of beer and off you go.
That was how I thought about it until a few weeks ago. Right now, if money would be no object, I'd consider the A1000 route with a little extra in the shape of Phoenix (http://www.amiga.org/forums/showthread.php?t=23782).
-
Well.. I can quickly think two good sides for A1000. Composite signal is color and it has separate keyboard :)
A500 is much more compatible for games and demos and is more easily upgradeable. It also has more memory by default.
-
@cmvsm,
As a collector of everything Amiga, I suggest you go with the A500. It is harder and more expensive to find working expansion parts for the A1000. If money is not an object and you can accept having only 512k Chip RAM and what ever FAST RAM expansion you are able to find working, then the A1000 is a more elegant design, and as you said, is more nostalgic. (finding an A1000 with a Phoenix board is another possibility, but very rare)

No!
Opposite end, same side up! A500 expansions sit with their rear end towards the user when in an A1000, but never upside down.
-
for nastolgic reasons (my first, and second) i would recomend the 1000. having a detached keyboard can be a really good thing.
also many if not all of the expansions that plug into the cpu socket for a 500 and 2000 will work for the 1000
these include accelerators (14mhz 68000, 68020, and even a 68030 irrc) also adeide and adscsi allow ide and scsi expansions too.
with my amiga 1000s the color composite was great, it is clear and then you dont have the 520 hanging off the back of the 500.
cpu socket stuff might need a socket extender and rom switchers might need some othe hacking to work so you can use roms
-
oh btw some (very few) a1000s dont have half bright mode. changing one denise can fix that though. again iirc
-
@KThunder
I thought that half bright was only available on ECS?
@cmvsm
Anyway, If you are considering getting an a500 have you considered an a2000? They are basically an a500 in a big box case and with zorro slots. AFAIK they are just as compatible as an a500 and much easier to expand as zorro cards are still on retail sale and the accelerators (if you want one) are more common.

@pedro7
the only thing ecs added was productivity modes
the early rev. a1000's didnt have hb both of mine had it
-
Thanks for the multiple responses guys. Seems as if half say the A1000 and the other half the A500. So I suppose perhaps the nostalgia facet of it all will tip the scales towards the A1000 side.
If I were to get an A1000, what upgrades would be a "must have" to get the machine to "respectable" standards. I will mainly use it for games and such. I'd like to give myself the time to explore the rest of the machine's capabilities as I didn't give it much of a chance in my younger years.
What significant capabilities, if any, would the A500 have over the A1000?
Thanks again for all of the input! :-D
-
Hi,
- mainly the frontal 256kb expansion if it's not yet in.
- a FastRam expension such as Comspec Ax1000 (1mb) or Ax2000 (2mb).
- maybe a cpu expansion or a 68010 ;-)
- maybe the big A1010 external drive

The A1000 uses the DIP version of the Agnus chip. It's not compatible with the PLCC version in the 500/2000. unless you find one of those phoenix boards. :-)
I've got a ROM board in my 1000, that's a handy thing to have.... autoboots from an external HD, so I don't have to worry about the broken internal floppy.
:-)
-
Yes, if you can find a Phoenix board for it, the 1000 will be a pretty amazing little box! Details (http://www.amiga-hardware.com/showhardware.cgi?HARDID=46).
-
Hi cmvsm,
While fitting things like a 1 or 2mb agnus and denise should help an A1000, changing or accelerating the cpu risks losing compatibility with games and demos. You then have to ask yourself, is the A1000 going to be a work system or not.
I would just stick with an A500 for all your nostalgic delight!

* There really are NOT any upgrades you will find these days, unless you use A500 expansion boxes.

* The A500 has newer chip versions, a ROM based OS, can house much more RAM, and there are upgrades that can still be found!
I have both machines (along with A2000, A3000, A4000T and A1200). If I had to have just one of the early Amiga, it would be the A500!
-
Kickstarting the 1000 is a very nostalgic thing to do - but very annoying if you happen to add a hard drive. Furthermore, Kickstart 2+ is out of reach without a ROM board. Nostalgic.
I'd rather go with a 1200 - faster out of the box, 2 MB RAM (even chip RAM), and the cheapest and most easily available expansions.

I believe there's a hack on Aminet to add a ROM to the 1000.

Bah! The Phoenix board is a whole replacement motherboard, not just an add-on card. That sounds like a cheat to me. You pull all the guts out of your A1000 (except the power supply and floppy drive) so you just have the empty case, then put in the replacement. Why not just put in a Mac motherboard? ..or a PC motherboard? (yuck!)

And if we look at, say, the Atari Jaguar, wich also only has a mc68000 chip?
-
Better first have a look at the hardware specs of the Phoenix before starting to shout. The Phoenix mainboard is a mix of technologies used on the A1000, A500 and A2000 (it has a video slot, it has a ZORRO II, it has the A1000 expansion port,....). To get a way with licensing it wasn't sold WITH the custom-chips in place. So you'd need a scrap A500 (or 1000) to get the custom-chips from.
So... it's an Amiga(ish), not 'yet another PC, MAC, Atari....'.
-
In regard to upgrades, I probably won't be doing too much of that to be honest. I'd like to get enough RAM into the A1000 where it could run most games without getting stressed. How much RAM would that be?
If the A1000 had 1MB Ram and the A500 had the same, would they be relatively equal in terms of game playing? Aside from the NTSC and PAL compatibility of the A500 of course.
Thanks again for the replies.
-
I've got an Amiga 1000 with 1Mb of RAM and I've also got an expanded A500 so I'm able to tell you exactly how it is. An NTSC A1000 will not be able to play PAL games or demos and this is a major drawback since about 60% of the best ECS games and about 95% of the best ECS demos are PAL. Also, some games that run fine on the A500 will have strange graphics corruptions or just fail on the A1000.
The colour composite output is a major bonus in the A1000 and so is the nice solid design (and A1000 "nostalgia factor") but I don't think these are enough to offset the lack of PAL support, compatibility, built-in-ROM or available expansions.
I can also now admit that I spent way too much on expanding my A500 when it would have been much cheaper and better for me to just buy an A1200. In fact, even though I've upgraded and configured my A500 as far as it can possibly go, I'm still planning on buying an A1200 so that I can go further.
If you're just planning on playing games, use WinUAE. If you're planning on having an upgraded Amiga with harddrive to play games with WHDload (which is waaay better than WinUAE), then get an A500 or A600. If you want to do even more, get an A1200. The A1200 is the cheapest and the best solution.
-
@mr_a500,
Is the lack of PAL a function of the different format Agnus chip or the lack of the Kickstart ROM? I expanded my first A1000 with a Kwikstart ROM board, internal HD with an AdIDE controller and used both 1.3 and 2.04 ROMs. I never tried installing a 3.1 ROM, but know that they work too.
I thought the newer ROMs from 2.04 foward allowed PAL or NTSC displays?
-
My A1000 is a PAL - 512kb + 2Mb FAST and it seems to run well NTSC games (like Titus the fox/Moktar) due to the presence of the big down black border.
A1000 is OCS not ECS :-)
And yes newer ROM allow you to switch between PAL and NTSC mode if your hardware allow it ! A1000 and first generation of A500/a2000 can't do it properly.
-
So there is a ROM for the A1000 that will allow it to switch between NTSC and PAL modes? How would one be able to tell if you had an A1000 that has the compatible hardware for this new ROM. Where would you find the ROM if you wanted to buy it?
As another post stated, I think that it would be important to have PAL and NTSC compatibility, but I'd love to have it in the A1000 if at all possible.
Thanks again for all the replies.

Eh? Maybe I've forgotten after all this time....
but I don't remember ever having an incompatability problem with the A1000. I had friends with A500s and we swapped games and demos all the time and it all ran fine. In fact they were all envious because I had a Commodore IBM 512k 4.7mghz XT sidecar(which was like the A2000 bridgeboard but even had it's own slots and I upgraded it with an AT/286 8mghz accellerator) with a hd you could partition for the Amiga and the A1000 could access it. That sidecar was pretty useful for highschool programming classes in pascal.
The only thing that annoyed me was booting up kickstart, and even worse booting up that Janus software to get the hd on the sidecar going.. But I digress.. I'm pretty sure the A1000 switched between PAL and NTSC effortlessly on my monitor (never bothered with the TV out though but what would you expect). Was I just lucky or something? I've got 2meg ram so the A1000 was fairly functional for the day. I bought my A1000 used after the A500s came out. I sought it out as a preference.
My only lament was the dependency on the internal drive to bootup kickstart and then having to switch disks to get workbench going. I would've rathered it would have booted up from my external drives if only to avoid wear and tear on the internal one. Actually if someone knows of a software fix for this I'd love to give it a go. I also have a 5 1/2 drive for it, and I wonder if the disks still work after all this time.
No, the A1000 is an excellent machine, but don't expect it to perform any functions required for today's computing experience. Just your basic games and demos and mucking around with some ancient apps. As soon as I get the space I'll be setting it up again. Of course, as a precaution I actually bought a spare A1000 cheap that had a wrecked case just in case I needed parts. It also still works.
A little while ago, I saw a company on the internet that were selling A1000s with x86 mobos inside them. It would be kind of cool if it booted up straight into a later and nice looking AmigaOS without flashing windows or Linux stuff at me.
I still reckon the A1000 is a classic in it's design. It is just so cute, especially with the A1081/4 monitor. And the keyboard garage. They just don't make them like they used to. I feel the same way about all the Amiga models that look different to your dull PC box of the day. I still love that machine and I haven't loved a machine since.
Ok. Going back to my happy place now. (http://64.33.47.100/images/a1000anim.gif)

The A1000 Agnuses for PAL and NTSC differ, so it's completely impossible to switch around. An NTSC Agnus will only show the top 200 lines (+overscan) for PAL screens and a PAL Agnus will always run a background colored/black border at the bottom for NTSC screens.
The first A500/A2000 Agnuses were the same, but when I expanded my A500 to 1 MB chip, the new Agnus was able to switch via software and some socket pin.
