Thanks to this post and a few other around the internet, I purchased a HP SDD018-n1000 (with the correct connector, not the round DIN plug some of them have)
And I check the pinout, to see it matched up with the Famicom Titler, the voltages don't match exactly, but they're close enough that plugging it in without any modification, my Titler was up and running without a problem.
So I can confirm the HP SDD018-n1000 works with the Famicom Titler without any modification.
You may well appreciate this video I made of my to Titler's running.
