Hi All, For a while I've been assessing the feasibility of using a PC as a sort-of-SuperCPU, getting PC software to run an emulation of the CPU and a cable /adaptor to control the write back and I/O read functions necessary. With modern PCs some pretty amazing CPU emulation speeds are possible, but its all brought back to reality by the need to write to the real hardware. I've now settled on an approach and have documented the aims and challenges involved. This information is posted on my website at (as well as an FAQ and tech-doc) www.64hdd.com/c64-proj.html#v6510 Keep in mind that the proposal I have is a balance between compatibility, speed, simplicity of the cable/adaptor, etc, etc. Surely, a dedicate PCI I/O controller could be designed and built, but "professionally made" this would cost as much as a SuperCPU (hence not worth while pursuing in my mind). I would pleased if there was some contructive feedback of the design /proposal, and happy to discuss the proposal on this forum. I've assessed many variations on the theme, so don't be surprised if I've already discounted some options. On the otherhand there are many pitfalls that I may have missed.
