PJ5 TTL CPU Hits 4 million instructions per second!

We've cracked the speed issues, we're now able to run the CPU at 4Mhz, i.e. 4MIPS!!! We've done new PCBs which remove the mod wires, and updated the Instruction decode to make things quicker, as well as the special register board. Again, we've not used any microcontrollers or FPGAs to do this, it's just discrete logic gates and some RAM. The only FPGA at the moment is emulating the fast ROM board, which has now been ordered, so that will be going soon!
