    Any extension readable by the Amiga can be put on the FAT32-formatted CF card. LHA, LZX, ADF, text, images, etc....

    When you insert the CF card into the AUX slot, a hard disk icon will appear on your workbench, just like any other hard disk present.

    It is really a plug and play.


    It would be totally redundant to use the standalone ROM, unless for whatever reason you decide to unplug the ACA00plus and run your A500.

    You don't really need the GoTek external kit, unless you want to run ADF floppies from it and be 100% like old times with your floppy reader.

    The ACA500plus can read FAT32 formatted PC cards, and that's what I use to transfer files between my PC and Amiga.

    The ACA500plus has 2 CF slots: the right one is the Amiga formatted boot drive, the left AUX one can be either PC or Amiga formatted. If PC formatted, it can be hotplugged and out. If Amiga formatted, it cannot be hotplugged.


    1. Yes the ECS V2 will work with all those products installed. No reason why it shouldn't. My rev 6a has just that same configuration and works like a charm.

    2. ECS V2 says in stock for immediate delivery on icomp's shopping site. Is it not so?

    3. You can certainly do it whichever way you want. But if I were you, I'd first install the ACE-2, do a reboot to ensure you at least see the ROM splashscreen (that should tell you the ACE-2 is well seated. if not, you might see a solid color screen appear). I would then proceed with the ECS-V2, and finally the easiest of them all, the ACA500plus.

    Hello Jens,

    here's the thing, when the game start, there is no switchover from the Indivision, hence no OSD output.

    Attached are 3 pictures:

    - the 1st one with the blue background is my standard workbench in 640x512 PAL, you can see the OSD output.

    - the 2nd one is just as I am launching the game, when WHDLoad starts.

    - the last picture shows the game just as it is loaded, as you can see it is shifted to the right.

    Upon quitting the game, everything comes back to normal just like the first 2 pictures.


    After spending over 45 minutes fiddling with the settings, I still don't understand how to make this work.

    My workbench is set to 640x512 PAL. All is good.

    When I WHDLoad a game (say Arkanoid, or whatever), it loads okay, but then the game screen shifts towards the right. There is a big dark border to the left, and it is truncated on the right. When I exit back to WB, all is back to normal.

    I copied over my 640x512 setting, changed the setting to 640x256, even tried to offset the horizontal display to the left, but still, nothing happens. I cannot for the life of me figure out how to make this work.

    Can someone please help? It's obvious I am missing something.

    Thank you


    just to let you know that my ViewSonic VA-951S connected to my A500 with Indi ECS V2 also experiences major ghosting issues.


    Edit: same configuration with ECS V1 did not experience ghosting.

    I've retrofitted 3 Meanwell RT-50B power supplies in 3 heavyweight A500 power bricks, that I am using with :

    1. Amiga 600 with Furia 020 accelerator, Indivision ECS, and IDE CF adapter

    2. Amiga 500 with ACE-2, ACA500+, ACA1221ec @ 42MHz (with heatsink), X-Surf 500, Indivision ECS.

    3. Amiga 500+ with TerribleFire TF530 @ 40 MHz

    4. Amiga 1200 with ACA1233n accelerated to highest warrantied speed.

    5. Amiga 500 with ACA500+ @ 21MHz and sometimes 28MHz.

    In all cases, those power supplies have performed absolutely brilliantly so far without an issue. The only issue I've ever had was a system hang once on the Amiga500+ with TF530, but that could have been due to something else completely unrelated to power.


    I do tend to agree that ECS V2's setup tool is quite counter-intuitive to use and complicated.

    Upon reading the docs over and over and over again, I somehow managed to luckily get the 640x512 PAL Laced setting to display properly on my LCD monitor, and I left it at that without further trying to try other stuff, in fear of losing that setting.

    One of my Amiga 500 is a rev 5, and it came with an OCS Agnus, which I assume yours does as well. The cheapest way for you would be to acquire an ECS Agnus PAL or NTSC and swap it out. You can then use your ACA500plus software menu to enable 1MB chipmem since you have that 512KB trapdoor expansion.

    You can acquire that chip quite easily on ebay, but you will need a chip puller to swap it out, it's a bit finicky and requires some skills and manhandling.

    I am trying the acaswitchcpu command. When run without any arguments, it reboots fine into the CF card with the host CPU 68020.

    But when given the command 'nm' (acacpuswitch nm) , the computer tries to reboot but gets stuck at the very beginning, black screen. The only way out is a cold reset.

    The aca1233n is bone stock without any mod but an RTC module installed on the MB clockport.

    Any ideas?


    your original A500 kickstart v1.3 is 256Kb, whereas the new kickstart v3.1.4 is 512Kb. Each ROM slot in the ACA500plus is designed to hold 256Kb worth of data. But if you copy a 512Kb kickstart to the ACA500plus ROM, it will just use 2 slots.

    you cannot load 3.1.4 into the ACA500plus as standard install, but you can certainly use it to install WB3.1.4.

    I have done that and it works great.

    You first need to flash a new rom into one of the available ROM slots in the ACA. (well it will use 2 slots, as it is 512Kb).
    You can use the acaflash tool for that.

    Once that's slotted in, you create a new advanced configuration in the F10 menu and select that ROM, and then either boot from the WB3.1.4 floppies and continue from there with the CF card formatting, WB install, etc... , or simply use WinUAE on your PC to create a WB3.1.4 CF card, and then you can just pop it in in your Boot CF Card slot and boot from there.

    Below my current 3.1.4 custom setup.

    Good luck

    It may sound like a simple thing to do, but I learned not to rate the difficulty level until I get feedback from the people who actually implement it :-)

    you, sir, are spot on 200% correct on this :)

    I'm still loving the ACA500plus by the way! I'm awaiting the new IndivisionECS to have even more fun with my old Amiga 500. And who knows, if I'm lucky I'll even add an accelerator and an X-surf to it.

    The ACA500+ is awesome. I have the ACE-2 2MB chip upgrade, along with aca500+, aca1221ec, RTC, and X-Surf 500, along with Indivision ECS. Running WB3.1.4 KS3.1.4 @ 42MHz (passive cooling) in PAL hires 8 colors, and the machine works like a charm.


    Is it possible at the same time to have one LCD monitor connected to the VGA port of the Indivision ECS, while having a CRT monitor hooked up to the RGB DB23 port ?

    I understand I will get the same display on both screens. I just wanted to know if it is doable for comparison purposes, or is it just one or the other type thing ?
