The Independent Magazine for the Entire Zenith Computer Community, The Independent magazine for Users of Heath/Zenith Microcomputers, For Users of Heath/Zenith Computers

Sextant's publisher/editor was Charles Floto. He also published the BUSS newsletter.

Thanks to ebay, I've completed my collection of Sextant Magazines. There was a total of 40 issues published. I plan to post scans of at least the cover and table of contents when I have some time. Here is an Index for Issues 1 to 26. I would love to scan/post complete issues, but I have not been able to reach Charles.

I now have a large collection of duplicate issues, that I'm willing to trade for other Heath/Zenith computer related items. Contact me at mark (at) garlanger (dot) com if you are interested.
