I'm not associated with this project in any way, but I'm excited to see the Beamspring (and Model F capsense stuff) is still ticking along. I keep meaning to redesign my controller for the 2020s but the original crappy design keeps working perfectly for my needs and I can't justify the time to update it. I'd love to do something dumb like throw an FPGA at the problem or try and use the RP2350 PIO. I don't think we ever matched what IBM's original ASIC achieved.
