Offered here is a Super RARE Mindset Expansion system. System includes the expansion unit and some software as shown. See photos. These systems were only offered for a about a year and with poor sales the company went bankrupt. This has been one of the top 10 computers in my collection. I have sold a Kenbak 1, Commodore 65, 232,264 and Amiga development system to name a few of the ultra rare items that were originally in the collection. Not done yet! Mindset items of any kind are almost never offered any more as they are now mostly in the hands of collectors. Box is decent, complete and intact but shows average signs of age when considering its 40 year old. This unit wastested about 10 years ago and functioned properly; then put in storage and untouched until now. Not retesting. I suggest it be checked before power up is attempted. Also includes some generic software, also untested. Price is high but find another one boxed. Excellent investment opportunity. I know I can never replace it. The remainder of my Mindset collection will be listed shortly and includes cartridges, manuals and software packages. Sold "as is" "Parts or Repair" due to age of electronics and no returns. I will not warranty machines this old but if it arrives physically damaged, it will be fully insured. After all it is nearly 40 years old. Buyer pays shipping. Thanks for looking.. I ship worldwide but shipping overseas will be very expensive. Maybe 3-400. Shipping is estimated. Please check out my other listings.
