I’ve only just got into FPGAs thanks to the Mister project, thankfully the people in charge of that project made a good choice for me. What they’ve achieved with the DE-10 nano to me is some sort of tech voodoo and I’m not easily impressed these days. £100 for the board and £30 for an SDRAM chip and I’m in retro gaming nirvana everyday. I’ve got a pocket sized, low power device that nearly boots instantly, pretty much perfectly plays every old machine from the the Spectrum up to the NeoGeo and GBA. RGB and VGA output, works with my Arcade stick, DS4, SNES/NES classic controllers, etc. Anyone with any interest in retro gaming who hasn’t yet dipped their toe in the water I urge you to give it a go. It’s probably the most exciting and vibrant open source community I’ve immersed myself in for many years.
A lot of the old silicon created in the 80's are unobtanium -- particularly certain chips in the Amiga hardware line.
