# 2023-10-23 — Dev notes

Without really reviewing older notes:

- I'm not sure if I'm keen on the IO setup described in the current version of the re-architecting architecture docs
- I had some ideas about extending to 16 bits?
  - Add an "H" register, to be used as the high byte, in an "HA" register pair?
- Need a M/Q register? (if providing MUL and DIV)
  - The 6502 doesn't have 'em... https://www.llx.com/Neil/a2/mult.html
  - Nor the Z80... https://tutorials.eeems.ca/Z80ASM/part4.htm
  
- https://www.reddit.com/r/beneater/comments/tcb76d/unpopular_opinion_rca1802_is_the_best_beginners/
  - TODO: read this more and reconsider 1802-informed IO
