Not A4000 schems, I have those.  The A4000T schems I'm curious about.

I have A4000T schematics on my webserver:
http://amiga.serveftp.net

They are for the Amiga Technologies machine.  I've scanned them from my photocopied photocopies, so the quality is a bit lax.  But they're a bit better than nothing :-)

So, what differences are there between the A4K and the A4KT on an electronic level? I trust you have loked them both over now.

The A4kt is closer in nature to the A3k than the A4k from what I can tell.  Incorporated SCSI, fixed the RAM issues, etc.  Frankly, the A4kT is what the A4k should have always been from what I can tell.

Now, to find a dead A4k mobo to test out my next idea with.  8)

Basically the A4000T is the redesigned version of the 4000D.
Many problems were fixed and a few new things added such as onboard SCSI plus the IDE controller.

It has rev 11 Buster and OS 3.1 (40.70) as standard, though most of the I/O, audio, GFX, chip mem, fast mem, etc is the same as the A4000D.

Zorro, video and IDE slots are mounted on the motherboard, plus you have 5 as opposed to 4 Zorro slots, making much more room for expansion.

The tower case was a standard AT style one, so you could use an off the shelf AT power supply, plus there was lots of room for drive expansion.
It had one of the "coin" type batteries for the real time clock, so you have less problems of leaking Ni-Cads which are currently causing many problems with many older models.

I have a dead A4000D motherboard here.  I have pinched a lot of SMD parts off it for other jobs, but you might be able to use it.
What exactly are you trying to do??
