Brief
ASICMiner Prisma is based on a proprietary X48 design for BE200. It greatly reduces power
consumption of the device per GH/s compared to the X24 design.

It takes the same cooling structure and similar form factor as the ASICMiner Tube,
while being even more efficient and compact. Also, we added cgminer support on Raspberry PI.

Spec
Hashrate: 350-370GH/s per hashing unit in normal mode, 1400-1480GH/s per full device.

Power consumption: ~0.67 W/G board-wise. On-wall power consumption relies on PSU
efficiency. (typically 1050-1100 W per full device, 0.75-0.78 W/G)

Size: 35cmx12cmx12cm per full device.

Weight: 7.5kg per full device.

Powering: One 6pin PCI-E plugs per hashing unit.

The hashing units are driven by ethernet controllers. It can also be driven by cgminer on Raspberry PI.
Each ethernet controller or Raspberry PI can run up to 32 units.

Round 1 Sales

  -- For other components, the requirement is that they don't function properly.

There are several different types of Bitcoin clients. The most secure are full nodes like Bitcoin Core, which will follow the rules of the network no matter what miners do. Even if every miner decided to create 1000 bitcoins per block, full nodes would stick to the rules and reject those blocks.

Does it have the same internal software problems as the Tube?
Or is the stratum implementation fixed this time?
Hopefully your custom cgminer version doesn't have the same problems also.

The cgminer differs from the main branch in only the communication to the device
and some part of the USB driver. Other parts are not modified.

It would also be open source.

So this is a nice way of saying: Yes, it indeed has the same bugs.

No, there won't be any stratum problem using cgminer with Raspberry PI.

The fixing of custom ethernet controllers' problem is still under way though.
