At first, I thought the Arduino was just a toy. The KIM Uno changed my mind, the "a-ha! moment" when I realized that the Arduino is the jello-instant-pudding of embedded processors. The magic ingredient that makes everything easier. The Kenbak-1 MEGA takes that to 11. It's an Arduino shield that looks and acts like the Kembak's front panel. Would you like to learn more? The KIM and SYM were the original 6502 trainers:https://en.wikipedia.org/wiki/KIM-1https://en.wikipedia.org/wiki/SYM-1 The KIM Uno is the modern replica: https://obsolescence.wixsite.com/obsolescence/kim-uno-summary-c1uuh The KIM Uno is a very simple "open-source hardware" project that started out as a replica of the classic 1976 KIM-1 computer. Later, Apple-1 compatibility and a 6502 programmable calculator mode were added, plus a built-in 'early 6502 software gems' collection. We just keep tweaking and adding. It costs about $10 in commonly available parts (board & parts without case or power supply), but provides a faithful KIM-1 'experience'. An Arduino Pro Mini mounted on the back contains all the logic and memory. *** https://www.kenbak.com/ Everything you ever wanted to know about the KENBAK-1 but were afraid to ask https://www.facebook.com/groups/352054786710322/ The place for lovers of the Kenbak-1 and its recent replicas!

By 1974, several other "first" computers appeared: https://en.wikipedia.org/wiki/SCELBI https://en.wikipedia.org/wiki/Mark-8 Featured in the July 1974 issue of Radio-Electronics https://en.wikipedia.org/wiki/EDUC-8 The EDUC-8, pronounced "educate", is an early microcomputer kit published by Electronics Australia in a series of articles starting in August 1974 and continuing to August 1975. Electronics Australia initially believed that it was the first such kit, but later discovered that Radio-Electronics had just beaten it with their Mark-8 by one month.
