I gleaned these preliminary specs from the A1k thread about ACA520.
Yum!


Thanks for sharing!

The preliminary specs reflects what has been written previously (except that the A1200-like trapdoor expasion bus is for ACA accelerators only - it's written that not every A1200 accelerator works - Apollo ones 1240 and 1260 won't).

It's great that Jens is making also such a product for A500/A500+ : I think he will be rewarded by sales... if the price is right!  :D

My opinion is that a price range around 100 EUR would fit (the lesser the better!), but I'm not aware of components and production costs (but I'm figuring out from other products from Jens).

Upgrading an Amiga 500, IMHO, is due to two possible reasons:
1) a more powerful machine for running games thru WHDLoad (never tried, BTW), stored on internal hard disk/Compact Flash card.
2) for trying to get the best performace possible out of that "good oldie" computer (pretty like me :)))  ). It's not rational, it's just like those who like "special old cars", and the emotions they receive by using them.  :)

In the first case, you get the ACA520 and you are happy with it.
In the second case, you get the ACA520 and another A1200 accelerator to get even more (here we have to see what works, and how it could be done "mechanically", to push everything inside A500 case).

I'd like to have a 68030-based A500 accelerator with 16/32MB of Fast RAM at least, but it would be too expensive for the first category of people.
With the A1200 bus solution you can improve the system further, even in two steps.

Since this news, I'm a bit sad that I recently bought an Apollo 520 on eBay (68020+68881 @ 25MHz + 4MB)... quite pricey... but I'm quite satisfied after all.  :)
...I'm thinking on building an adapter to place it internally, since I already have an Oktagon 508 by side, and placing it there as well, puts my SCSI controller even further on the left!  :?

BY and thanks Jens!

I've already got a trapdoor expansion, so I'd like to have some sort of module that could pop onto the side expansion bay of my A500 and make it super duper.  Flash memory, ethernet, RAM expansion, etc.
I'm sure it'll never happen unless I do it myself, but I just don't have the skills or money right now to do something that sophisticated.


Hi!

From what I (we) know, this new accelerator for A500 (ACA520) is an internal one, and will be placed on the 68000 socket.
Moreover the A500 trapdoor expansion has nothing to do with it; the trapdoor in the previous messages refers to the option of connecting more powerful accelerators designed for A1200 trapdoor expansion port.

For your request, since the ACA520 will have a clock port, you could buy a Subway USB card, a 030 based A1200 accelerator (to make Poseidon, the USB stack, working), and a USB->Ethernet adaptor, and you have what you need!  :)

Of course it will be pricey, but you can buy those things separately, at different times.
BY!

So correct me if I am wrong; out of the box this accelerator card is planned to have a 14 MHz 68020 and the option to add 8MB of FastRAM. Am I right? If so, then, the A1200 adapter (which I understand will allow A1200 accelerator cards to be used with the A500/A500+/A1000/A2000) will allow the use of let say a 68060 CPU with an A500+?


8MB are not an option: they are there!  :)  (as from specs)
For the adapter, theoretically yes, but it has to be tested board by board specifically.

P.S.
The message has been updated with possible price and other details:

...seems I was right with my price tag.  :)

I've got a question (maybe Photon can answer since he's near Jens)...

Will be possible to mount the ACA520 together with the Indivision ECS inside the A500?
I really hope so (and I think so).  :)
