It Never Fails
sneak the upgrades past my wife electronically later?
Another variance of Murphy's Law: my purchases will be delivered at the exact time and day that my wife happens to be near the front door |

the good thing about ACA 1221 is that people won't have to buy from weasels selling 4 MB trapdoor expansions for 100 UK pounds on eBay

For the ACA1233, all features are available right from the start, but the ACA1221 will always start with 17,03MHz. That's a safety precaution, so a processor that isn't overclocking-stable will not keep you from using it from a cold-start and enter the refund code. It's not a secret how to set a different CPU speed. We may either make that part of ACAcontrol open-source, or you'll implement a simple tool under Linux that does the job. Quote:

You're better off feeding them mashed fruit and veg.

Cool, this may be a fun little project. I picture implementing it within the framework of cpu frequency scaling in the kernel, AFAIK it would be a first for m68k, hehe.

One ACA1221 pre-production unit has just reached San Jose, and will be shown at the 30-year Amiga event this weekend: www.amiga30.com

Will a fully unlocked unit match the 1233? I had been saving towards that but at my rate of progress this may be a better choice.
Great idea by the way. I appreciate the scale of affordability on offer here. Something that has been painfully missing to people like me. Also, will this board have the same timing fix requirement of the 1233? Finally, will the 1233 ever be available again? It has disappeared from the usual online retailers. Oh, and if I sell it later - does the new buyer retain my upgrades? Sent from Ubuntu Touch using the Forum Browser app |

This card only has a 68020 chip AFAIK - which although overclocked wont match the 68030 on the card you are talking about.
The website also suggests that timing fixes may be needed as with other ACA cards. |

No, it won't. The ACA1233 is clocked at 40MHz, and the 68030 processor has two caches (instruction and data) instead of one (instruction only) that the 68020 processor has.
The faster memory interface of the 68030 gives it about a 10% advantage over a 68020 at the same clock rate. Since the ACA1233 runs at 40MHz, and the fully unlocked ACA1221 runs at 28.38MHz, there's quite a difference between them: http://wiki.icomp.de/wiki/ACA1232#ACA_12xx_Benchmarks I have already entered the ACA1221 in that table, and you can sort it by clicking on the colums' arrows. The "big plus" of the ACA1221 is a new method to speed up chipram access, and the all-new-to-the-Amiga-computer property that the clock speed can be changed on the fly - something that modern laptops can do today is now available to the Amiga!

Thank you Jens. I hope this is a success and leads to more products in the same vein.

Isn't the "market" flooded with low end hardware already?
I don't mean to be negative, but each new a1200 accelerator is more boring than the last in recent times. Or do people really only use their a1200's as whdload machines? Seems a waste. |
