AmigaOne Questions

Cheers Amigans.

I am finally into the stage of waiting my AmigaOne XE board to arrive. Yes I have finally managed to find one mobo plus a Radeon GFX Card and of course I got a lot of questions.

1. I want to buy this sweet cube case form Amiga kit. Does the AmigaOne XE board fits into this? Is it designed just for the Micro A1 boards or an xE can find its way in there?

2. I am planning to buy a CateWeasel. Which is the latest edition? I guess it is connected via PCI but does it have the current voltage amount to work with AmigaOne XE board? Is it 3/5 or 5V ?I do not remember the number well-?

3. In general how many voltages the PCI cards should be to work with an AmigaOne?

4. Has anyone tried those cateWeasel drivers for OS 4? Do they work? Thanx.

Thanks in advance for all your answers.

1. This case is designed for microATX boards therefore bigger boards like A1XE won't fit.

Thanx. what type of box will I need for AmigaOne XE? MiniATX or bigger? What type of Mobo is the A1 XE? Is it a MiniATX?

@CountRaven

There's nothing 'micro' or 'mini' about an AmigaOne XE - it's a 'big box' Amiga and as such requires the same as any other type of standard desktop PC (ATX?)

Rude!

The A1 is very much an ATX case. When you see it you'll see what we mean. :) Mine's in a midi tower.

The PCI supports 5V and 3.3V at 33MHz. It supports 66MHz too but only if you don't use the AGP slot, which is where your Radeon should go.

I have no experience with the Catweasel in the A1 but I remedy that shortly. It should work just fine though.

@CountRaven

Right, look here:

AmigaOne HW Table

Rude!

Those are the specs of my hardware:

A1-XE motherboard
750GX CPU module / 800Mhz
512 MB certified RAM
Radeon 7500 AGP video card

Can it be mentioned as a G3 or G4 model? -Accorrding to the board it is a G4 but I want to confirm. Also the CPU type mentioned on the board is 745x mine is 750GX does it makes any difference?-.

Where there both G3 and G4 models of AmigaOne XE released?

@CountRaven

750GX is a G3.

So I guess there were both G3 and G4 models available.

I have an A1G3-XE, and showconfig shows it as a 750FX processor.

@CountRaven

Yes, both were available.

@Swoop

Its just a different type of a G3.

@CountRaven

My A1 is in a CoolerMaster Mystique case, with a Corsair power supply. Any case that has room for a full size ATX board should work.

I have a Catweasel Mark III in mine. It works OK. Snuffy has a Mark IV, and has had some issues with it. The "drivers" -as such- sort of work. I can read, write, and "Format" (by writing an empty ADF image) Amiga and PC floppies using my MKIII.

Cooling has always been an issue with the A1's. . . although maybe not so much for the G3's. Be sure you have an effective cooling fan of some kind for the CPU.

Make sure you start off with a brand new 2032 coin cell battery on the motherboard when you put it together. It's easier at that point than when it's in the case and surrounded by cables.

@CountRaven

The A1XE never came with a 750GX processor. What youve bought is a XE with a micro A1 cpu module. Whoever sold it to you probably has a micro with the original 750FX module from your XE.

Reason for the swap could be that the person who sold it to you may have been having stability problems with a micro and therefore swapped the cpu's over.

If you have any stability issues I'd get in touch with the seller and ask why you didn't get the original XE cpu.

Catweasel MK3 and MK4 work OK in the XE, only used it for reading data of old 880K and 1760K disks.

4.

Some have reported problems using the old driver I have uploaded to OS4Depot,

I have a beta driver, but I don't know if there is issues whit it.
I have not worked on the driver for long time now.

it supports DD,HD, PC MFM, Amiga MFM.
Amiga DD, Amiga HD. PC DD, PC HD.

Joystck ports not supported.
SID chip not supported.

Alfa/Beta drivers are available only on request.

Can i point you at this thread, maybe you can help out ?

Or maybe I bought the board used from another fellow who fried the original CPU 7451 module (known to overheat) and his dealer put the 750GX CPU module in its place.

Just make sure you buy a good quality power supply for the AmigaOne. You will run into all sorts weird nonsense if you buy a cheapass power supply.

Good power supplies are usually the ones that have an efficiency of at least 80%. And how do you know if it has that? If the specifications don't say anything about it, it is usually not that efficient.

SID chip is supported but only when using VICE, I have a MkIII with SID chip.
The only problem is that sound samples in the later games music do not play you just get a clicking noise, but this was down to a hardware fault on the MkIII. There is a work round for the Windows driver that would play them, as far as I know the MkIV has fixed the problem but can not confirm how well it works on OS4.
Does anyone have a MkIV with SID chip as I would be interested in how well it works with VICE.
