2006-Feb-28, Tuesday 18:44* I might have a place to live; I'll find out tomorrow morning.
* I wrote out code for a multiple-byte multiplication routine, having to make an additional instruction. It seems I'll need a number of different formats for 2-byte opcodes, but the single byte opcodes are not very well patterned yet (e.g. as to which bit specifies the register operand). I'm also working on the map-register format and the map changing instructions, as well as the port pin assignments -- I wish I remembered the 8032 assignments. Even though this is a 16-bit processor, 40 pins should work. I just googled and found the info, which I've written down.
