Introducing ACA 1221 Low Cost Accelerator At AmigaKit.com

[TenLeftFingers]

[/QUOTE]if I have any of these unwanted caps I guess it just removing them with a soldering iron.[/QUOTE]
I'm in the same situation. I imagine they'd need to be replaced with something if they're part of a linear circuit or else the circuit will be broken?

I'm not bad with a soldering iron once I can actually get my hands on one. Is it really as simple as carefully removing the offending capacitors? Obviously taking care that the very old tracks don't get lifted with the pads. Maybe they could just be snipped at the legs?

They have no legs, they soldered on tracks - http://i49.tinypic.com/swtptv.jpg
No big deal i think. Even a blind drunk with shaky hands like myself could do this job.

Paid vesalia order today. Guess I will be only person with accelerated Amiga 1200 in the country.

I think the only real objection to Jens' purchasing format is purely reactionary given the plague of in-app purchases and pay-to-win models we've all seen. Personally I would never abide by pay-to-win and as a developer myself would never be involved with any application of that ilk. It just rubs me wrong.

But Jens' model just isn't the same. Personally I don't have a problem with it. OK it may seem a little annoying that the hardware is "there" but you can't have it, but in reality he's keeping his production costs down and giving everyone a fairly cost-effective upgrade to existing machines.

My only real question however is this. The A1200 already has a 14MHz 68020 in its stock form. Other than the memory upgrade this card offers, is an '020 running at 28MHz really that much of a performance increase over stock? And given this card starts out at 9MHz, isn't that a little... off?

It just seems to me that even though this is a nice memory boost, money is better spent on one of Jens' '030 offerings.

Or have I missed something? Of course other than the modular software upgradable options...

If you just want to have a WHDload capable system (which is what many people go for), getting an ACA123x doesn't offer much benefit over this much cheaper option. The games will run just the same and 9MB will also be plenty of memory for most games with preload enabled.

The base model has two speeds, 9.46 MHz and 17.03 MHz, which is slightly slower (whdload mode) and slightly faster (the fastest Jens can guarantee without time consuming tests) than an A1200. This is how I understand it from this thread.

[Schoenfeld]

GhstWlf: Correct, the base model offers those two frequencies. The overclocking options add more frequencies, keeping the slower clock rates available.

As for speed and performance of the "seemingly same" processor, you should know that real fastmem just beats the crap out of Chipram, giving the same processor a substantial performance boost. A very simple rule of computers applies here, one that will always remain true: A processor can only be as fast as the memory where the instructions come from.

Also, the ACA1221 sports a full 68020 processor, not the 68EC020. This gives it the possibility to access more than 16MBytes of address space. If you only add fastmem to an A1200, you'll max it out at around 10MBytes. The ACA1221 on the other hand can give you a total of 63MBytes of memory.

Hi everyone,

turned out that our shop system isn't fit for "downloadable products" yet: If you want to pay with PayPal for one of the upgrade licenses, you'll get an error due to the missing shipping address (this confuses our PayPal module). We're working on a solution.

Ordered mine tonight

Good to know. I was looking for that last night as a matter of fact.

[LieutLaww]

Mine should be here today or tomorrow hopefully

When will the new ACA 500 firmware come out?

If I buy a RapidRoad where do I connect the ground cable on the ACA 500?

There is no release date yet.

Not at all, because the two clock ports of the ACA1221 cannot be used on the ACA500. Only the ACA500plus will be capable of making use of clockports on an A1200 accelerator, but on the old ACA500, the clock ports must remain open.

PayPal-trouble is solved now. Licenses for the ACA1221 can now be paid with PayPal.

I think he meant to connect RapidRoad to the clockport of the ACA500?

Got mine this morning it is a lot smaller than I expected lol, and just paid for the upgrades as well

[Kehil]

Ordered mine today, first expansion for my A1200 since 1995

[Dejavu]

@amiga1260

check this photo of my setup.

I also have a RR and connect its ground cable to same screw where the Indy ECS's ground cable connected.

Jens, since you are reading here - I have been annoyed that I cannot really navigate icomp.de using any browser on my iPhone, so I have tried to find out why - there is a typo in the CSS used, "id="teaser-contaoner" - I am sure it should be "container". No idea if it is related to the site not working well on iPhone though.

[Schoenfeld]

I'll look into that. However, the non-mobile compatibility is a known issue, because I just don't have a theme for small(er) screens. Just didn't get around to installing one. Next work block on the page has been completed, part of it will go productive tomorrow (e-Mail notification feature for registered users).

Also, the ACA1221 Wiki entry is complete now: http://wiki.icomp.de/wiki/ACA1221

Dämn im gonna get one. Jens just saved me ebay money and time consuming ebay sniping for old Blizzard cards

[Dagger]

Have received mine today, nice quick delivery Have fitted the card and installed the aca1221 folder to my root directory. I di'nt realise the card would have to be set up before you can make use of it as by default it only gives 1mb of memory so to access the other 8mb I need to enter commands into the startup-sequence. Now this is where I am stuck as I don't know what to type in Can anybody help me out please. I also have ver 3.0 kickstart so I understand maprom has to be used.
