The Premium Plus was a limited-edition kit from Microbee Systems, but we don't
have any technical info or schematic as yet. It starts up, keyboard works, disks
work much the same as a 128k or 256tc. It has 1024k of RAM but we do not know how
the extra RAM is selected. At this time it has 256k allocated and it seems happy enough.
The kit itself has an extra custom FPGA CPU board with memory-card slot, but there's
no info on it yet. We just emulate the Z80 portion.
