WarpEngine 040/40mHz in A3000T???

Useful facts which might help you out.

Some A3000T units came with int2 already installed at the factory so you might not need it at all.

Some A3000T units also do not come with an IC chip which is required in order for accelerator cards to work stable. It's a 14-pin gate array chip made by various different manufacturers. The one that I've got in my A3000T is GD74LS08. Look at  this picture and see the empty socket close to the accelerator slot to understand what I'm talking about. Does your socket have a chip in it?

No A3000 (D or T) works without a SCSI device attached! Try to boot it at least with a terminator in the SCSI connector.

This is not true. If no SCSI devices are attached, both A3000D and T should display the kickstart insert disk screen.

They might not boot if your SCSI chain if not configured or terminated properly though.

Did your 3000T come with the int2 mod? I hear that some came with the int2 mod but I never have heard from someone that had one.

Yes, it came with the INT2. The underside of the motherboard does not have the patch wire installed, and when I install an accelerator in the cpu fast slot such as CSPPC for example I can boot off of its scsi controller and see cybppc.device in HDToolBox including all drives attached to its chain. This can only mean that INT2 is already there.

Are you referring to U103? What does it do? I have used a 3640 and CSMK3 in my machine without it. The only problem I have is with the newest Ramsey and DMAC causing SCSI problems with certain accelerators like the CSMK3.

I believe that it "somehow" adds stability to the system when an accelerator card is installed. If you search old usenet posts about U103, I am sure that you will find a more detailed explanation. I can't remember exactly why it was left out by Commodore originally, but probably to save costs as in those days they must have thought that very few people will actually need an accelerator card in the A3000T.

edit:

Here is one link that I've googled that makes a reference to it. Click here.
