Hi, I have one complete Northstar Dimension and another only missing some parts of the power supply. Northstar Dimension computers are quite rare machines from the era of transition from S-100 to the IBM PC clones. There are also a couple of Northstar Advantages in the original boxes. The Dimensions are also in the original boxes. There are some spare parts for the Dimensions and Advantages including some software and maybe some documentation. One more item is a NorthStar 15MB external hard drive. This is quite a large and rare unit. At least this is the only one I've ever seen or heard of. I am not 100% sure but it looks like it may be a 14" hard drive platter. Seriously, this thing is as big as a full sized S-100 chassis by itself. Due to the nature of these items, they are for local pick up only. I am not interesting in shipping these items. There is also some NorthStar software in original boxes, packing, etc TSS/A HD Horizon Order Entry and Invoicing HD Advantage (2) Inventory Control and Analysis HD Advantage Graphics BASIC DOS PIO Advantage Info Manager II HD Advantage TBS/OS Advantage Enhanced WordStar Advantage CP/M (5) Enhanced WordStar Horizon dBase II Advantage CP/M (3) dBase II Horizon 8/16 Upgrade Advantage Accounts Receivable HD Horizon NorthPlan FD Advantage NorthWord II FD Advantage TurboDOS 1.1.1 Horizon NorthNet Advantage (with board) CP/M 2.2 Rev L1.0 Horizon General Ledger HD version Advantage Accounts Payable HD version Advantage Image Maker Advantage CP/M TurboDOS I am willing to sell but due to size these need to be picked up (Ohio) in person.
