Here is a brand new A to Z for the April Blog Challenge. Missed this for a few years, but now returning with a kind of quick reference guide to gaming systems including original consoles, handhelds and home computers. PC's, emulation boxes, minis and mobile devices don't get included, this is a list of dedicated machinery for mostly playing games and educational software. This is valid up till March 2018. If anybody notices any missing systems you feel belong in this list, feel free to contact me.
The years stated are years of release, not when the system ended production.
