Piggy-Back Paula replacement doable?

[eXeler0]

Not that it makes a lot of sense (especially with Apollo-core team hinting at 16-bit sound in future core upgrades for Vampire v2), but just out of curiosity: could a piggy-back "sound-card" sitting over Paula be made as a Proper Sound upgrade for certain small boxed Amiga models. The clock-port versions don't seem to quite fulfil this promise... (or?)

No, it doesn't make sense. The clockport is a better connection.

Well the simple fact that are a bunch of expansions for the clockport and (so far) no piggy back solution for sound obviously tells me that its not the best (or easiest) idea...
But Im more interested by the technical reasons.. So could you elaborate with some technical details? Thanx

It's just a horrible method of connecting anything, which means support headaches for the manufacturer.

Feasible as intermediate connector (Paula removed from socket and installed in new PCB which is seated in original Paula place), better than clockport (at sompe point but best is to use two buses - one from chipset and second from CPU), perhaps in future single chip solution will provide such functionality.
Eventually Paula HW emulation.

As Pandy mentioned, A500s have socket ed Paula. I have a Blizzard Turbo Mem in one of my 500s it sits in CPU socket... It's a Phase product..
Indivision works well enough also.
But ye, if it's on a surface mounted chip it can fall off.. but other than that.. are there no advantages over clock port? (Clock port is 8 bit with shitty bandwidth.)
Pandy are u saying a hybrid solution would be most optial?

All i'm saying that today at this place no one should say "this is not possible" - we see many HW based on something that few years ago was highly unlikely to happen but today it's just happen.

From my perspective it is clear.

We need to decap ( [ Show youtube player ] ) and map all Custom IC as schematics ( http://www.degate.org/ ) - after this we can create identical (functional) custom chip that later can be used as a core for a new one. Add to this software - this forum have plenty great software guys so i assume with one HW such approach is feasible.

To avoid problems with limited clockport throughput a HDD connector can be used - there is 16 bit bus there.
