*DMA sound channels.
*Many many more.
 
== Known Flaws==
 
The Asmtrad Plus ASIC improve a lot of old CPC capability.
Yet this was a bit flawed.
 
*Despite removing some tasks from the CPU (Z80), the ASIC had to use specific central memory addresses, so took away this memory from the CPU...
 
Not that important for a 64Ko Ram system (464+ and GX4000) yet this is a serious limitation when dealing with Extra memory (6128+ and Extra Ram peripheral)
 
*There's a DMA bug (Help needed).
