RE: HP35 - A&R and C&T chips - How is the Pointer communicated?
The ROMs also generate word select directly from the instruction.
The LOAD CONSTANT instruction is decoded in the C&T chip (Is bus) where the P register lives. Do a search for HP-35 - Rob Weinstein. He did a fantastic job recreating the functionality of that calculator down to chip level. Awesome. cheers Tony |
