This is an auction for a system on Ebay which might be interesting. It is listed as a "Northstar Horizon" but has what appears to be a single board system marked Ferguson. That would probably not be from Northstar. Also it is built up with 8" floppies which is even less related to Northstar. it appears he got a pile for a Northstar system with the Ferguson homebuilt which is in an Incoterm box which holds the floppies. There is a listing for a bigboard on bitsavers which is probably for this system. http://www.ebay.com/itm/400301360595 Price may actually be something if anyone feels a burning need for a Ferguson board, but I think its high for an ordinary Horizon. Too bad there is a missing Horizon.
