emulatorII-list

Hi Guys, 
I'm trying to establish a SD/Powerbook 5300c (OS 8.6) connection with my EII, but they won't recognize each other. I wonder why it won't work?  I get the same EII keyboard to work with a Mac Classic without problems. (I would like to use the powerbook instead as it has a big HD) Rob at Emu-archive has this listed as a proven system...??! I tried to switch apple talk on/off and virtual memory too. Any ideas what else I could try?

Thanks!
