I like the idea of putting newer chips on a 30 pin PCB a lot better than some contraption that plugs into the old SIMM sockets and provides "modern" 72 pin sockets. For one thing the PCB is gonna be a lot larger (= more expensive) and a lot more complex. It's pretty trivial to pop all the chips off a SIMM with a heat gun, hotplate or hot air reflow station and then reflow them onto new boards. I use a temp controlled hotplate I built but I've seen it done with various low tech solutions including a thrift store electric skillet. Anyway the end result has a tidy stock appearance that will fit easily in any machine, not a messy hack with a multitude of wires snaking around.
