Eager spec-chums will remember that just before Christmas I added this to my stock Amiga 1200:

It's a compact flash card and came pre-installed with lots of (PD games - Ed). Very wonderful it was as well except the poor old Amiga was clearly struggling. Because you have to boot Workbench (OSX for the Acid House generation), it meant you didn't really have enough RAM to run most of the (legitimate pieces of software - Ed) included as they had been altered to work from hard disk.
Also, clearly the Amiga couldn't keep up with the speed of the card. Although loading was fast often things would come to a crashing halt while the Amiga got its knickers in a twist . So for example games that had music during loading would have the music stuttering and the screen flashing while the poor thing tried to keep up.
Second hand accelerator cards are expensive. But luckily those nice people at Amigakit came up with this, the ACA 1230/28 accelerator:
http://amigakit.leamancomputing.com/catalog/product_info.php?products_id=1002It's a brand new accelerator card for the Amiga that boosts the CPU to 28MHz and the memory to a huge 64 meg of RAM. The cost is £86 but this is considerably cheaper than a second hand board from the mid 90's that comes with no guarantee. This board also has modern, faster, RAM on it. More of that later.....
So I duly ordered one up. There's quite a demand so mine took 2 weeks to arrive.

Best part of an hour to slot it in. I have a very early A1200 (an early UK made model) that requires part of the metal tray that covers the main board to be bent back slightly as it restricts the expansion port. I also had issues with the fit being so tight I had to file away a part of the inside of the case. Newer 1200's won't have this problem.
Eventually after much coaxing and having to take the whole case off twice, I got the card in properly. The bad news is that it still doesn't sit quite flat but it does appear to work fine. Nothing is being strained, it's just the card refuses to sit flat.

Bad news is the door won't go back on the expansion port due to the slight angle the card is sitting at. I have contacted the retailer to ask for help. It is known that the bay door will need modifying for all installations, but mine is protruding by more than it should.
So, what's the result? Well the Amiga is all round faster, I can run Workbench in more than 4 colours and all the games load. The dreaded stuttering also appears to have vanished. But most surprising of all the machine clocks in much faster than an A3000 with the same processor thanks to the modern RAM and the clever engineering employed on the card.

And here's a shot of all that lovely free memory:

Word to the wise though. The card comes with a floppy disk that you have to install before Workbench can see the extra memory. This involves altering the Amiga startup file. Fairly simple once I worked it out (it's just one command).
It's not the biggest upgrade in the world, but it makes the Amiga superbly usable with a CF hard drive. You can run whatever software you want and the machine feels far snappier. I've also noticed that my LCD screen is happy running interlaced screen modes in Workbench so you can go as high as 1280x512 which feels really odd on a computer from 1992!
In all, a really good addition to my Amiga without breaking the bank. A faster (and more expensive) version is available and the same people have produced an A600 accelerator as well.
Not a final score because I've only had it working for a few hours, but I give it a provisional 985 Bananas, even if it was a pig to install. Anyone who doesn't have one of the initial 1992 batch of A1200's should have a much easier time.
