Emulating the machines you list in an FPGA only really makes sense if you put the microcode in block RAM, until recently the devices at prices most people could afford didn't have enough block RAM to do this. In the meantime, most inpu

I don't think it is healthy for most of the commercial CAD industry to rely on one proprietory kernel and exchange file format like Parasolid.

We spend a lot of time working on the correct type system for STEP, I don't think that using an untyped format like JSON is a good idea. I know that ISO 10303-243 uses JSON but in hindsight I think that was a mistake.

The MIT/LMI/TI Lisp Machines were not, they ran a simple RTOS written in "assembler" that checked for interrupts from devices and woke up Lisp threads to handle the event. The assembler code also interpreted the instruct

One road not taken would have been to port the MIT/LMI/TI Lisp Machine software to stock hardware, it was 32-bit until the end so didn't need an Alpha as the host. A fast 68020 with a custom MMU would have been fine. There wa
