Ok well I guess we can agree to disagree, I think in either situation I learned an STe always needs a blitter. Whether you told me or not. What if I didn't see your hint and decided to do lots of pointless work on it for no reason?
It's not like guiding someone on a schematic.
Just to add to my point.. I *always* try to save you time on the forum by answering basic questions that might *sound* basic to us, but are not to others, like here: https://www.exxosforum.co.uk/forum/viewt ... f=9&t=4881
I don't have to do that or be so helpful. It's a respect thing.
STe freezing on floppy/dma access? [solved]
Re: STe freezing on floppy/dma access? [solved]
In fact not jumpers, as Atari prefered to use "zero Ohm" resistors instead (like for the ROM configuration). Search R111 and R112. (Sheet #1 of the original schematic, and p3 of my reworked schematic). You can see them in one of my close-up pictures (image 20 of 42) on this topic https://www.exxosforum.co.uk/forum/viewt ... =51&t=2141 , they are between the CPU and the "phantom footprint" of the external blitter (my motherboard is a later revision without any option to install an external blitter anymore).
The later revisions of the MCU have an internal blitter.

Not strictly true. If your mobo doesn't have the space for the links shown in the below rev-A schematic, you could short the BGI/BGO and BGKI and BGKO pins on the back of the socket.
This (well the first one -- BGK works differently), is the direct equivalent of the jumper on the expansion port of the Falcon.
