Question regarding A1200 IDE bus

[Wain]

I read somewhere (don't remember where) that the A1200 was pushed into mass production with a few manageable bugs still in the system, the most major one being a lot of CPU taxation on the internal IDE bus.  

I was wondering if anyone knows if this issue was ever resolved, and how much more CPU usage are we talking about compared to IDE generated via a different controller(which has an already much higher rate of CPU taxation than SCSI).

It isn't really a bug per se, more like a cheap design descision..

I agree that something like that wouldn't really be a bug, just the thing I read made it sound like the engineering department really wanted a little more time to make the whole thing flow better, and were unhappy with having to go to production with it like that.

Okay, so it's unbuffered non-DMA IDE (eeewww), got it.

that's all I needed to know...

Thanks.
