I had an AKF12 that I used to run off RGB on an expensive (in its day) 
LG DVD player. Awesome picture.

But, well... one day something in the PSU let out its magic smoke so it 
was back to the crappy old telly...



To drag this (lamely) sort of on-topicish, I was slagging off the slow 
crud-worthy awfulness of an MP3 player, saying that the thing seemed 
such a pile of .... that it was probably running a Z80. Smack my gob 
shut when I dig up a datasheet to find the (Sigmatel?) MP3 DSP is, 
basically, a DSP with a Z80 clone attached. I think it runs something 
like 16MHz, and can address a whole 64K of memory. ;-)

So.. I was just wondering. We all know the TI DSPs are ARM based, but 
there's a lot of cheap'n'cheerful audio players. Have any of them ever 
been based around a DSP+6502 combo? I think if you tried for one of the 
WDC versions (extra regs, extra addressing space...) you could have a 
fairly capable little SoC; if not quite as nifty as an ARM combo.


Best wishes,

Rick.
