An Olduino is a retro-Arduino. It uses a processor from the early days of computing but adds hardware and software so it can function like an arduino and use some arduino add-on shields. The Olduinos is more limited than an Arduino but that is part of the fun.

My name is Bill Rowe. I built my first home computer in the 1970’s from the Popular Electronics article. I got out of hardware hacking in the 1980’s but came back when somebody gave me an Arduino in 2008. When Lee Hart made the little Membership Card I thought “Hmmm Olduino?” The Olduino has been through several generations of hardware and software and boasts its own C compiler. I have enough development plans to keep the project going for a while. You can reach me through the form below or directly as bill_rowe_ottawa at hotmail.com.
