I've been considering how to add some "functionality" to my
C64's (strictly DIY, I'm not interested in getting an REU,
but, rather, building something like an REU)

The 82C206 is an "integrated peripherals controller" which
includes (among other things) the equivalent of two 8237 DMA
controllers and a 74LS612 memory mapper.  I see junk ones all
the time, and I know they're still available surplus.

I wonder if this has ever been done, or if any of you
"hardware hacker" types have ever considered it or have any
thoughts on the matter.

I'm particularly curious about what would be involved in making
an 82C206 based, REU type device work with existing REU software.
I know there's general info on the REU's but is there any detailed
info on how (for example) GEOS accesses the REU.
Or maybe source code for an REU RAM disk that works with stuff
like GEOS.

(I don't necessarily care about GEOS specifically, I'm just
using it as a compatiblility benchmark/standard)

Comments?
