Title: CSG Super DMAC?
Post by: Iggy on November 03, 2013, 02:36:34 AM
I've never seen one of these before.

Anyone care to take me to school on this component?

Add this to the list of ridiculously overpriced Amiga related "junk" on fleaBay.  Just because it's rare doesn't mean it's worth $500.

THAT was what I was waiting for.
Because I don't mind paying big dollars for something that has its uses, like a high speed '060 or PPC processor board, but just enhancing DMA doesn't seem worth the investment.

If this is a PROTOTYPE chip then it probably doesn't enhance anything. In fact, it's more likely to have bugs than the production chips.

When you see "RARE" on evilbay it's usually just another greedy seller hoping to take advantage of some poor buyer's ignorance! :eek:

Another good point.
And hardware doesn't run by itself, it needs software to drive it.
Since this part is non-standard, it might not work at all.

I was thinking that as well.  That's, like, a Rev. 0 of the chip or something, probably work worse than stock, LOL.  :p
