Old thread yes but I thought I would do a little follow up on the OPs quetsion.
Most Huntron Trackers had or have an accessory that allows for using DIP clips for scanning ICs. Currently that would be the Sacnner II or Scanner 31S used with the Tracker Model 30.
Older "scanners" would be the Switcher 640 and DSI700 used with the Tracker 2000. The Switcher 410 was a manual push-button "scanner" that could be used with just about any Tracker.
Thanks.
