max232: those are cheap stuff: i bought them below 4€, free postage from China.
User port connector: kinda expensive from Uk, ~3€/piece.
You need a db25->db9 converter. Usually if you buy an rs232->ubs converter for ~4€, you get one free in the package. I think i have one free, i may give to your project.
The rs232 mouse idea is not mine, but from BGSSZ, I linked his page in a previous mouse topic. He had no drawings, circuit diagram or parts, so i started from beginning. He had an unoptimised sw to regularly read position into register. I planned to optimise it and to support paralelly SID mouse too. Sprite emu was not in focus, planned to be used from BASIC with Gshape mouse cursor, in my planned adventure.
