48GX Custom ROM Card by Ford?

[rprosperi]

I can't identify the card or the manufacturer, however I recently acquired a 48SX/GX program card of identical hardware design (no shutter, bare metal sides, no battery, wide plastic grab-handle) with some kind of (I believe) Surveying application loaded.

Title: T&D Utility Pac
Version: 1.0
Company: Laser Technology, Inc.
Copyright: 1998
Labels: Laser printed stick-on on front side & "T&D Pac" in the hole in the plastic grab-handle

I think this supports Raymond's suggestion that these are either OTP or EEPROM cards, and used by various VARs and Corporate users for limited qty. runs of program cards.

I looked through later issues of the EduCalc catalog (all issues are on Jake's DVD) but could not find any listed; I was hoping there may be a photo in the catalog.
