Adding blitter to 1040STF (70789 board)

Is there anything else I need to do to add the blitter besides soldering the chip itself? I’ve seen a mention of a patch board but that was for a Mega ST... Thanks!

As far as I remember, you have to cut two bridges on the board (near the blitter socket).

I found the info on Exxos site, but my MB doesn’t have these two bridges... hmm...

what about W4 bridge above the BLiTTER socket (C070789-001 Rev C)?

and there is the BLiTTER upgrade in C070789-001 Rev B:

I can report it works great. Also got 4Mb and TOS 1.4 installed, time to actually start using it...
