Compiling my own SPARC CPU inside a cheap FPGA
For those interested in hacking in this:<p>The Pano G2 FPGA is a monster, but prices on eBay have gone up a lot. My cheapest buy was 25 of them for $85 (including shipping!). They now go for around 1 for $30 if you’re lucky... or $200+ for many.<p>The Pano G1 (with VGA instead of DVI) is cheaper but has a much smaller FPGA, though still large by hobby standards.<p>The benefit of the G1 is that all interfaces are working now, including DRAM, USB, Ethernet.<p>Last week, Skip Hansen got a full CP/M system running on one: <a href="https://github.com/skiphansen/pano_z80" rel="nofollow">https://github.com/skiphansen/pano_z80</a><p>USB on the G2 is hard. A bunch of people have tried and failed.
