I have a major announcement.

It's time for version 2.0 of my book, "Abacus to smartphone: The evolution of mobile and portable computers," which I published on dead trees four years ago.

This time, it's going to be a (free!) interactive website: the era of printed books is behind us.

Please help me raise funds to make this happen. Funders will get exclusive access for the first month that the website is live (approximately the whole of August 2019).

All of the details (such what's new/different) are here: https://fundrazr.com/b1WZ91?ref=ab_74VRia ... please check it out.
