This is complete rubbish. The MCA machines go up to 686 class with up to 4GB of memory (admittedly, this is with the NCR MCA extensions).

So what actual problems has it had that are causing these issues. I'm still listed as MCA maintainer and I haven't seen any. As far as I thought, it was nice and cleanly separated and builds just fine for me.
