Hi
It was good to see that BillHendersson Idea of using a PC with emulation running as an expansion card might work. I even looked around to see what the price was on the smallest possible motherboard like the Pico itx, if one should take this idea and make it into only an expansion card. Converted from my currency it would go for around 230 pounds. It would be something like 3 by 4 inch card.
But I was specially intrigued by Karlos way of looking at this. A cpu+ a translator. Intels mid range cpu’s cost virtually nothing and fpga’s cost virtually nothing. I found this on wikipeda on the 060. Remember I’m an enthusiast, I don’t have deep knowledge.
“The 68060 shares most architectural features with the original Pentium. Both have a very similar superscalar in-order dual instruction pipeline configuration, and an instruction decoder which breaks down complex instructions into simpler ones before execution. However, a significant difference is that the 68060 FPU is not pipelined and is therefore up to three times slower than the Pentium in floating point applications. In contrast to that, integer multiplications and bit shifting instructions are significantly faster on the 68060. An interesting feature of the 68060 is the ability to execute simple instructions in the address generation unit (AGU) and thereby supply the result two cycles before the ALU. Another point of interest is that large amounts of commercial compiled code were analyzed for clues as to which instructions would be the best candidates for performance optimization.”
I also find out that Intel’s processors are very backward compatible.
So it all comes down to this converter.
Have no one done this before?
Is there nothing that just could be altered for this situation??
