I picked this one up at a Garage Sale a month or so ago and thought I'd post both pictures of it and also some details based on paperwork that came with it around its intended use.
The unit and tapes inside appear unused. The tapes are still all shrink wrapped.
The history of this unit (based on the receipts inside) are as follows:
Shipped 03/05/1990 to a woman in Auckland as part of a study course called "Personal Computing" by a company called "ICS Australasia"
Probably these guys? http://skillscentre.com.au/about-us/
Unfortunately while the tapes are present the cassette unit other course material is missing apart from a list of modules covered.
Clearly they didn't follow through with completing the course!
