Up for sale is a NeXT Color Workstation ("slab"). I recently bought this wanting to upgrade but it's not worth the time nor the money. So someone else may find the wonders of using NeXT. PM me here if you are interested. There are no warranties explicit or implied, this NeXT Color Workstation is sold As-is. Here's some more info:
430MB SCSI hard disk, memory maxed to 32MB
Comes installed with OPENSTEP 4.2 with the latest patch 4
supporting Y2K and has a DHCP patch installed on it and is ready to be added to your network.
Asking $65 shipping not included and it IS heavy. Let me know if you're interested.
