A3000 if you want my $.02. I'll take SCSI and the sexy A3000 look over an A4000 with its IDE any day of the week. No busted simm sockets to worry about either!  :lol:

+1 VingtTrois!

External scsi cdroms are a pain.

Let your A3000 out of the closet, I'll give her a good home  :)

...and external CD-ROM? Who uses CD-ROMS anymore? People without Deneb, that's who.  lmao

What the frack is Zorris? 5-1/4" Drive bay today is useless and white vs. beige vs. brown? lol    Service wise, the A4000 is a surface-mounted budgeted POS compared to the A3000. I am disappointed the '030 and '882 aren't socketed on the A3000 - but I think you are way, way off here comparing the two machines from a serviceman's standpoint. Besides all that, when your accelerator card goes out in an A4000, what are you left with? The processor isn't even a part of the mainboard! lol

The A1200/A600/A4000/CD32 are all piles of rubbish from a service techs pov. They're all as disposable as the company that designed them. How convenient and non-forward looking they were.  :(

@magnetic:

All I'm saying is that I bet there are or will be more A3000's in use years from now than A4000's. And I bet you're right about the number of A3000 machines you've serviced/upgraded than I, but I am no stranger to board repair - 25 years in electronics repair that is. I know a better, more serviceable design when I see it and the A4000 is not a "better" design by any stretch. Short term maybe. And only 20 years ago. But crap components and shit materials are used throughout. Legacy A4000 and AGA in general will nigh be a shit stain in computing terms, let alone PC history. My impressions are all I'm projecting here   :)

...and this talk about "cramped" case design, I agree with C=John. Hardly. A3000 has plenty of space for reasonable upgradability. Screw 040 cards w/ their large power consumption and fan reliance... who's gonna bother with that shit? If they're so inclined, I bet they know how or would be willing to cut themselves through some sheet metal for better airflow. lmao   3.3v 060 cards, no problem. No cut, no fuss, no muss!   :lol:

Hahahahahah! Good one Paul1981, I know I opened myself up to lots of flaming, but there are plenty of "service techs" that can repair old Legacy Amiga's. Who repairs the newer stuff? Pretty much just one guy and he's in France. Experiences seem to vary with him too.

@Magnetic - no need to run an accelerator on my A3000. 25mhz 030 with the MMU_tools is as fast as I need this machine to be. Faster than my iMac G5 in some respects  :)

Guys and gals, at the end of the day- you gotta know... I love all things legacy Amiga, but I do believe C= skimped and cheapened out big time toward the end. It's only natural that they did. I'm not only talking feature wise (debatable obviously) but quality wise as well. Whatever. If your mileage varies, great! Keep on enjoying your machines.  :)

About SMD silly comments: SMD in fact causes that failure rate is much lower because you can rule out easily bad contacts, chips coming loose, cracked sockets, users inserting chips in the opposite way... it saves power and allows designing smaller boards. Even the A3000 uses SMD for its 030.
Yes, as I stated - the 030/882/881 is smd. That was stupid, but it was done for cost reasons. Surface mounted components and my observation of them are not silly. I am a tech in an industry going 25+ years servicing motherboards. In theory, what you stated is true: smd's equal less maintenance. That was all and good within their (the company's legal liability) useable lifespan, which is 7 years. In reality, smd components still suffer the same fate as socketable components: only that they are that much more of a bitch to deal with and diagnose than previous designs. I deal with several computers and circuit boards daily. Replacing a socket (rarely necessary) and more likely, cleaning the legs of a chip are much more desirable than dealing with the uncertainty of guessing (or using precision instruments) which one of those tiny bastards are to blame in dealing with smd components.

@magnetic - I do recognize soldering a NiCad battery to the mobo, where it was so close to vital componenets was retarded. For sure. Horrible, horrible design. But again - 7 year legal liability lifespan. Can't tell you how many other consumer electronic companies did similar things.  :(

Ask an "engineer" why they do the things they do to placate the FCC or other legal "entities". There's politics behind consumer electronics and who always gets to sniff the glove? why you and I of course.

Oh, almost forgot... wasn't the polarity reversed on some/most of those smd capacitors in certain A4000 revisions? Not just talking about on the 3640 card either. I've had at least 2 A4000 mobo's come through here that needed their caps replaced. One of the audio caps leaked so bad on one board that it took out the entire area and the components around it. Similar damage as that of a leaky battery.
