I have for sale a NeXT mousepad. It is black with the logo. This is an official company item, gotten from an ex-employee. $35
Hardware wise I have a 030 mono cube motherboard that comes in a NeXT box. Box is pretty neat as a collectors item as well. $55
Also have a working mono slab. No OS on the harddrive. $55
PM me is you are interested. Thanks!
