I found this item on eBay: a Tektronix Microlab I with 8086 personality module, but can't seem to find much about what capabilities it provided. It doesn't seem to be in the same league as the Fluke 9000 series (9010A etc) so what could it do? Was it simply a way of testing out different microprocessors (like a SBC with plugin CPUs)? http://www.ebay.com.au/itm/380885770121
