Classic 8bit is too constrained, but how about 8bit++? 6809 with some 16bit I mean. To avoid price, obtainability, reliability problems go the FPGA route. There is an interesting design at turbo9.org for a 6809 implementation. (impressed by the team BTW) Video with very balanced discussion about design choices over here : https://www.youtube.com/watch?v=8ScT86RKopQ Bitstream for Arty-A7-35 exists so maybe it can be made to run on this : https://machdyne.com/product/kirsch-computer/ (disclosure I am a total n00b at FPGA, but I appreciate the effort of designing a board). Check out the Machdyne Timeless Computing philosophy to see if this resonates with you. WIBNI we could have a hypersonic version of the Dragon 32? Up to 2 orders of magnitude faster... Might even run a version of Lisp for 6800 if BASIC is not exactly your thing.
