David Banks has developed a multi-processor miniture coprocessor based on a Xilinx Spartan FPGA. It implements the following CPUs:

DIP	CPU	Speed	Startup banner	Recommended Client
0	65C102	4MHz	"Acorn TUBE 65C102 Co-Processor"	Tube65 v1.12	resources
1	Z80	8MHz	"Acorn TUBE Z80 64K 1.21"	Z80Tube v1.21	resources
2	6809	4MHz	"6809 TUBE 64K 1.00 "	Tube09 v1.00	resources
3	80286	16MHz	"Acorn TUBE 80286 768K"	Tube86 v1.01	resources
4	BIST
5	Disabled
6	Disabled
7	PDP-11	32MHz	"PDP11 TUBE 64K 0.40 "	Tube11 v0.40	resources
8	65C102	32MHz	"Acorn TUBE 32MHz 65C102 Co-Pro"
9	65C102	16MHz	"Acorn TUBE 16MHz 65C102 Co-Pro"
10	65C102	8MHz	"Acorn TUBE 8MHz 65C102 Co-Pro"
11	65C102	4MHz	"Acorn TUBE 4MHz 65C102 Co-Pro"
12	Z80	112MHz	"Acorn TUBE Z80 112MHz "
13	Z80	56MHz	"Acorn TUBE Z80 56MHz "
14	Z80	32MHz	"Acorn TUBE Z80 32MHz "
15	Z80	16MHz	"Acorn TUBE Z80 16MHz "
	68000

The CPU can be selected by setting DIP switches or by using *FX 151,230,n. The changed CPU comes into effect at the next Break, with the CPU set by the DIP switches selected at Power On. The high-speed CoPros overwrite the startup banner with the processor speed. GitHub wiki StarDot discussion
