There's one open FPGA toolchain out there, and it's for Lattice iCE40 FPGAs. http://www.clifford.at/icestorm/ David Sent from my iPhone > On Dec 6, 2015, at 5:10 PM, ben wrote: > >> On 12/6/2015 8:39 AM, Tor Arntsen wrote: >>> On 24 November 2015 at 22:42, Mouse wrote: >>> >>> What I was rea

Just in case anyone wonders, the Oberonstation uses a Xilinx XC3S700AN aka Spartan-3 FPGA. So far, I haven't found anything that says that the code for the FPGA is open source / documented. Ok, scratch that, I was looking at the http://oberonstation.x10.mx/ site. Over at http://www.projectoberon.c

Perhaps Oberon required something faster than the 70ns - 85ns tRC read cycle / tWC write cycle times supported by the Micron cellular RAM running in asynchronous mode on the Nexys 2 - presumably because the data path is only 16 bits? That said, most "retro" computing would, I expect, be perfectly
