Should be nice if you have a ACA1233n-55.

Sold out for a long time now, at this moment I’m happy with Aca500+ and the Aca1221lc. Every demo and game works.

Thinking about the ACE2b, what are the advantages of this if everything I have now is already working?

Your A500 have 2MB CHIP RAM with the ACE2b which is the same as the ACE2. My must be set on Force PAL in the ACA500Plus menu. Use it on the Rev6A board maybe I would buy the ACE2b for my reserve Rev6A board.

2MB CHIP RAM is great for WHDLoad some Games have need more than 1MB CHIP RAM. But that are not so many Games that use 2MB CHIP RAM. That goes also with the 68030 card. It would be faster if you use 2MB FAST RAM and a 68030 card. Think about AOS 3.1.4.1 - BestWB 1.3 or BestClassicWB 1.5 and iGame V2.

The ACA1221LC is a nice little card but like the old ACA1221 / 28MHz better because the 63MB FAST RAM and some WHDLoad Games works better with a 68020 card than a super fast 68030 card such as the ACA1233n-55.

Would be great to buy a ACA1260 for my A1200.

I ‘overclocked’ the cpu on the ACA1221lc who’s connected with ACA500PLUS+ with the ACAtool to 40 MHz.

Now the A500 is running at +40 MHz, very fast in every thing I do and so far no problems at all. It’s going from Cowabunga to Smell the rubber 😲

The ACE2b is on the wishlist.

With the CA-PSU you can do 40MHz all day long. It’s fast for a 68020 card and the IDE Speeder would be faster.

If "everything is working" for you at this point, then spending the money on ACE2b would be a waste. For many applications, 1 MByte of chip ram already works nicely, and your Sysinfo screenshot indicates that you already have a 1MByte Agnus chip. The ACA500plus will already do it's "ChipMap" magic to turn the internal trapdoor expansion into chip ram, so you have 1MByte of chip without soldering inside your computer.

Remember that Phil has the ACA1221lc on his ACA500plus, where the IDE speeder of the ACA1221lc is not active. The high speed of the CF card slots comes purely from the transparent 32-bit access that the ACA500plus does with every 32-bit accelerator, not just the ACA1221lc. This means that in your case, which is obviously the first ACA1221 with full 32-bit address space, you might want to think about the update to logic version 1.3, which allows 42.5MHz operation if all options are licensed and switched on. CF card speed is the going to be almost same as with the ACA1221lc - minor differences to be expected, as the ACA1221lc is still a good deal faster @40MHz than the ACA1221 @42.5MHz due to the optimized memory controller.

Thanks Jens for clarifying this about the ACE2b.

And yes, the speed of CF cards is faster than my A1200's PCMCIA card and CF HDD with the Blizzard 1230 IV. But for my use it is also fast enough.

Both Amigas boot faster than my latest Apple MacbookPro

Had also a ACA1221LC with the ACA500Plus V1 and got with the CF card around 7MB/s. The ACA1221LC was running 40MHz. Like my old ACA1221 v1.2 more than the ACA1221EC and the ACA1221LC what I have sold this year. Now my setup is with ACA500Plus V1 with the ACA1221 is running 28MHz with around 6MB/s on a CF card. My second ACA500Plus V2 with the ACA1233n-55 is running 55MHz with around 7MB/s on a CF card. The ACA1221LC and the ACA1233n-55 give a extra 1MB/s with the ACA500Plus because of the IDE Speeder on it.

The ACA1221 v1.3 is very rare and yes it can reach 42.5MHz. My ACA1221 I use is only for some WHDLoad Games which don’t like the ACA1233n-55 such as Secret of Monkey Island. The best option from the ACA1221 is the 63MB FAST RAM which don’t have the ACA1221EC/LC. If the ACA1221LC has the same amount of FAST RAM as the ACA1221 than it was a great 68020 card.

The ACA1221LC it get around 3.4MB/s on a A1200 such as the ACA1233n-55. Hopefully the ACA1260 would run faster than that. Had hope that the ACA1233n-55 run faster which was for me a let down. For the rest the ACA1233n-55 is faster than than my two Blizzard 1230 IV cards.

Get on my A500 a boot of 8 seconds to see AOS 3.1.4.1 - BestClassicWB 1.5. With BestWB 1.3 it boot 10 seconds. That is with the ACA1233n-55 on the ACA500Plus V2 (7MB/s and use of the Indivision ECS V2). Which is 6 seconds faster than my old Indivision ECS V1 with a Super Denise chip on it.

My A1200 with AOS 3.1 - BetterWB 4.3 and the Indivision AGA MK3 it boot 14 seconds. That use the Blizzard 1230 IV with the FPU and 128MB 50ns. The Indivision AGA MK2CR is very slow around 22 seconds.

No, not because of the IDE speeder, as that's not even switched on when operated on the ACA500plus (see register description in the Wiki). I developed the thing, so I wonder what data you have that lets you say otherwise The speed gain is due to the faster memory controller(s).

Quote from JohanSSID

If the ACA1221LC has the same amount of FAST RAM as the ACA1221 than it was a great 68020 card.

Plain impossible, as the 68ec020 processor does not have the address space.

Careful - this sentence sounds like you're claiming a different boot speed because Indivision ECS V2 is installed. This can't have an influence on boot time.

Quote from JohanSSID

The Indivision AGA MK2CR is very slow around 22 seconds.

Same here - if you are observing different start times between systems equipped with different flicker fixers, it's absolutely not due to the flicker fixers. Remember that correlation not automatically results in causality.

Did it also with the Blizzard 1230 IV / 50MHz with a 50MHz FPU on the ACA500Plus and it did 6MB/s. And that have a fast 128MB 50ns on it. The memory on the ACA1233n-55 is not so fast than on my Blizzard 1230 IV. Have also test it with a old ACA1233n-40 with no IDE Speeder on it. And that have 6MB/s the same as with the Blizzard 1230 IV. Strange that the ACA1233n-55, ACA1233n-40 with IDE Speeder and the ACA1221LC have 7MB/s with the ACA500Plus. There most be something else that makes a extra 1MB/s than a faster memory controller(s). Maybe it’s the AOS 3.1.4.1 with BestClassicWB 1.5 / BestWB 1.3. Did the same with AOS 3.1 with BetterWB 4.3 and have around 6.7MB/s. Is little slower but fast for a A500.

Is that also the case with the ACA1221EC. Than I be very happy with the ACA1221.

The Indivision ECS V1 and the Indivision AGA MK2CR have during boot and reboot screen faults. It change resolution before it correct to the end of the boot. The same is on the Indivision AGA MK2CR. Maybe the BenQ BL702A monitor don’t like it and correct it latter on.

With the Indivision ECS V2 and the three Indivision AGA MK3’s it go perfect and fast.

The splash screen does not change the boot time of the computer. In fact, the computer can't even detect whan the splash sreen is shown. So again, your numbers are plain wrong (or they are not even numbers, but simple mis-perceptions). There is no technical explanation, and your claim won't be supported by any scientific approach.

It have a delay of 4 seconds before it go on the Indivision ECS V1 and the AGA MK2CR. There many things that boot can go faster such as recapping or higher Blocksize 4096 bytes and a faster ACA1233n-55. There also difference which brand and type CF cards. Some are fast and some are very slow. Use SanDisk Ultra 30MB/s 16GB CF cards.

The Indivision AGA MK2CR is a difficult flicker fixer to understand. Than the very easy settings of the Indivision ECS V2 and the Indivision AGA MK3 which make sense. A big thanks for the many updates that help a lot.

Is the ACA500Plus menu system firmware v0.135 the latest or come there in the near future a new update out. The only down side of the Indivision ECS V2 is the resolution size of the ACA500Plus menu. And it don’t see the name of the ACA1233n-55 on the ACA500Plus.

You can see that is around 7MB/s with the ACA1233n-55.

The ACE2 is a great upgrade. Would be interesting the new ACE2b.

You are not making sense - neither the flicker fixer, nor re-capping can change boot times. Just stop it, you obviously lack the technical foundation.

Quote from GianDO

news about the new version?

Good and bad news: We're working with a rather low level of staff during these days until the end of the year, so work in the shop is "almost zero". However, the first ACE2b units have passed QC and are only waiting for the sticker to be put on them (not sure if I wrote it here, but the PCB company messed up the writing on the board, so the orientation can't be seen easily - we are now putting durable stickers on).

With quite a few changes coming up (Brexit, higher VAT rate in Germany), and the "almost zero hours" of workshop time, it won't be possible to put the ACE2b on sale this year, as that would create an accounting problem: The sale being done this year and delivery done next year will require us to charge 19% VAT, but the shop system is still set to 16% VAT until the afternoon of december 30th.

The plan is to set the shop to maintenance mode on the 30th, after the last shipment of the day has been done (probably around noon). VAT will then be increased to 19%, as we don't do shipments on the 31st. You will then be able to place a pre-order for an ACE2b, for delivery during the first week of 2021.

Now Brexit deal is "done" and the free trade agreement with the EU remains in places, is this just business as usual for UK customers?

I still need to read up on that. Will only do that after the agreement is really signed by all entities of the UK government. After all, it's Britain, and anything may happen.
