Thanks John,

just out of sheer curiosity: how hard would it be to convert the 6502 second
processor running on a ICE 40 Lattice FPGA?

The open source development tools for the ICE40 are only Verilog based but
I suppose this not being a problem.

Subject: [BBC-Micro] Acorn 6502 and Z80 2p on Terasic development boards


Some of you may be aware of my 'soft' Acorn 6502 and Z80 Second Processor
implementations for several Terasic hardware development boards (DE1, DE0
Nano and Cyclone V GX Starter Kit).

Today brings a revamped release :

- All development boards now served in one download
- Proper HTML documentation (with pictures :-))
- Support for two new development boards (bringing the total to five)
- Clock now freely selectable on all Second Processors (basically any
  integer number of MHz)
- Increased maximum clock speed for the DE0 Nano Z80 2p
