2023-11-12 18:08:58 Oh, I realized that I don't lose access to half of the the 32655 address space if i use 16 bit xt's. The cells are still 32-bit cells, so all the things the xt's point to are 32-bit aligned. So I can shift that 16 bits up a bit or two, and there you go - I can cover the whole 128k space. 2023-11-12 18:09:57 That means I can only have one bit for "status bit stuff," but I'm starting to think that will be enough. 2023-11-12 18:13:20 re: the "immediate bit" vs. "compile vocabulary," I still haven't thought it all through completely, but I lean toward trying the compile vocabulary approach, just based on Rather's opinion. The only reason she cited for them not doing that was that it didn't comply with the standard. She clealry seemed to think it was a superior approach. 2023-11-12 18:14:05 So what I'll use that one status bit for is "xt = address" vs. 'xt = opcode."
