I find it very interesting that I am still getting offers for microcomputer memorabilia. Of course it is just great and satisfying to still be collecting however I have not been in an acquisition mode the past few years.

Update 3/7/16 - This computer like all the others in our collection are headed for the Computer Museum of America.  The truck with this computer arrived in Roswell, Georgia last Friday 3/5/16. I still have a number of people contacting me about donating and I will be accepting vintage computer systems and passing them on to the Computer Museum of America. 

Here is an email from a few days ago 11/29/15.

  Hello, My name is Jessica and I was wondering if you would be interested in buying a TK-80 microcomputer or if you could lead me in the right direction.  There isn’t much information that I have found about it but I know it is rare. I have attached some pics for you to look at.  Please let me know if you are interested or not or if you would like more pics. Thanks!

My response - Hi Jessica - Thank you for the information about your TK-80 computer. I would have an interest in purchasing the TK-80.  Please tell me the  price you hope to get for this computer.
Warmest Regards, David Larsen

Good morning David, I’m really not too familiar with vintage computers and have found little information about this one in particular. It comes with everything in the pictures.  On the inside of the box there is a written note that says “shot LED” but I see it comes with a new one. (I put that in the pics as well).  What do you think it is worth??  I trust you know about these computers way more then I do and will make me a fair offer. Thanks, Jessica

Jessica and I agreed on a price and the computer is now a part of the Bugbook Computer Museum.

TK-80 is a training kit for 8-bit microcomputers released by NEC Corporation (NEC) in 1976. In February of the same year, the Microcomputer Sales Department was newly established within the Semiconductor Department, and began selling new microcomputer chips. With an appeal by the head of the sales department at the time – “Think of a new idea using microcomputers, anything!” – the TK-80 was born. Source ISPA Computer Museum. 

At Ueno,  in Tokyo the TK-80 shares a display with the well known Busicom calculator.
