I added some items on Vintage Computer and Gaming Marketplace for classic SGI 1600 PCI and Apple Mac II NuBus machines. http://marketplace.vintage-computer.com/other_items.php?start=0&limit=1… ner_id=100048&item_type=all&order_field=a.end_time&order_type=DESC Please contact me if interested. Thanks and have a nice day! Andrew Lynch PS, there are still a couple of NorthStar Advantages for sale. One is in original packaging and another wrapped in plastic. These are for pick up only in the Dayton Ohio area. No shipping due to the fragile nature of these classic CP/M computers.
