It won't fit the Phase 5 1260 because they have a 90° simm socket which will only allow single sided simms to be fitted. The SCSI IV kit has a 45° simm socket so there shouldn't be a problem.
That is what I thought, but I worry about the length as well...
I also have one 64mb double sided SIMM that won't work because the chips on the back are too close to the base...
just want to be sure before I order something from 1/2 way around the world

Trying to decide if I really NEED more than 96MB anyway
thanks, nate
