Thanks for the suggestion, I've added this license to the project.

The main reason is just due to me knowing my own limitations. SRAM is really simple to interface with and i've not yet tried to write a DRAM controller since its much more complex.…

Thats an oversight on my part, I should put a license on it. I would love for anyone to be able to build one or tinker with the code as they want to. After all I was only able to m…

The bus controller was fairly straight forward. I found the timing diagrams in the V20 datasheet to be pretty easy to follow. The clock for the CPU is generated by the FPGA which I…

I built an IBM-PC-XT compatible computer using a mixture of authentic parts and a modern FPGA. The article linked contains a detailed description of the development process, and at…

a busy loop waiting for an interrupt to fire?

Oh fantastic! this makes me super happy to hear :) I'd love to play with it.

You mention that you have traced out every transistor from die photos, and I was wondering how much work there would be to make a netlist for the 8086 like that which was used to p…

What I'm curious about is how this has been done. I don't think that the source for UT99 has been released, so does icculus have access to the source and has then ported it to emsc…

This is great, I've been wanting an ISA card with an FPGA on it for a long time so that I can experiment. I've ordered a few of these PCBs to build some myself. Its very kind of th…

I've honestly never seen .C used in the wild. I imagine anyone whose written a bit of portable code would immediately realize this is a bad idea.

Its still blows my mind that he fit this in ~1k LUTs. I'm new to FPGA but the closest I got was about 4.5K LUTs for a comparable core. I wish there were more easy to access materia…
