I remember seeing the announcement for these years ago as a kid and being fascinated with them. I've always wanted to find one to tinker with, even to this day. I know they were probably not very widely adopted (I think they were mostly used in university and/or government clusters), but I've had almost no luck finding where to get one of these. I think I once saw a few of these on eBay in an enclosure that Terra Soft sold for them, but the listing was in the five figures and basically advertised it as a collector's item.
Anyone have any idea if these still exist or where to find one anymore?
