Kenbak: Maybe the first PC, but now you can own one

"Controversial" only begins to describe the ongoing debate about what was the first personal computer.  A widely accepted answer is John Blankenbaker's Kenbak-1, developed in his garage from 1970-1971.  Others prefer honoring the Datapoint 2200, but that was more of a business- and industrial-oriented minicomputer.  Alas, Blankenbaker and his associates created less than 50 Kenbak-1 computers, with only 14 or 15 known to still exist -- so expect to pay anywhere from $10,000-$15,000 if you find one today.  The good news: Blankenbaker recently gave his endorsement to a new replica kit dubbed the "Kenbak-1 Series 2" from Grant Stockly (of AltairKit.com fame) with the first units priced at $999, based on original blank PCBs and flawless copies of the original manuals.

Other kits are sexier, like the Briel Computers Apple 1, or incredibly geekier, like Spare Time Gizmo's PDP-8/E clone, or just a whole lot simpler, for example, Minds-On Toys' Digi-Comp 1 v. 2.0.  But none of those let you impress friends with a "first PC" claim!  So give Grant's kit a try: he's got a good reputation in our hobby, he built something very unique, and the accuracy of his kit vs. the original (thanks to Kenbak historians like Erik Klein) is very impressive.

Posting a shameless self

Posting a shameless self plug as AC on Slashdot really doen't work when you say "I write it." then give a link to your own blog. So, the AC part was kinda wasted. You get an A for effort thought! ^__^
