retrotechnology: reuse of old technology, particularly but not limited to machine tools and computers. History of old technology trends and how they reappear in new technologies of the 20th and 21st century.
This site includes "Herb's Stuff", a support and sales site for S-100 computers (IMSAI Altair Compupro systems of the 1970's and 80's); for floppy drives including 8-inch; and some older computing technologies including Apple Mac computers.
Thanks for visiting this domain. We will update this page with site changes as they occur. Check back for details. But refer to the sections mentioned here for specific and current information. Last edit of this page Jan 01 2008.
For old computers, follow this link to see the Herb's Stuff home page.. I have a variety of "classic" computer interests, about computers of the 1970's through early 1990's. My biggest and oldest computing collection is my S-100 personal computer equipment and documentation from the 1970's and 80's.
I also sell older Apple Macintosh equipment and parts from the earliest Macs to PowerMacs. Among other old computer items, I have some Multibus, STDbus and VME cards and manuals; some old SGI and Sun computers, also some DEC and DG equipment.
For floppy disks and drives starting with the 1970's eight inch drives, check my floppy drives Web page. We have manuals, technical notes and discussions, actual drives and diskettes for sale.
For test and repair of old electronics, I have some electronic test equipment that you may be interested in purchasing. Also I have some odds and ends bits of equipment and books that I've found while obtaining all those other items. I've even obtained a number of Pentium/Windows laptops along the way.
The "personal computer" was NOT invented by IBM in 1981. The history of CP/M development in the early and mid-1970's, including early products of Digital Research and Dr. Gary Kildall and his colleagues, is on this page.
A dominant popular personal computing standard of the 1970's and 80's, was the S-100 bus of the Altair 8800 by MITS and the IMSAI 8080 by IMSAI. The history of S-100 development is on this page.
Since August 2007, I've been working at the MARCH vintage computer club on an exhibit of a PDP-11/20 system from 1970. It was used to develop document scanning technology for the U.S. Census and the Post Office, by the National Bureau of Standards (now NIST). MARCH resides at InfoAge in central New Jersey USA, will include many original DEC documents and papertapes for the PDP-11 line. Look at these items and the system as I work on it, at this link.
Retrotechnology.com was established in 2003. This is the PRIMARY site for Herb Johnson's "Herb's Stuff" Web pages. Sales from those pages support this site and these activities. If you have old links to me at "njcc.com", please change them. The alternate domain name to "retrotechnology.com" is "retrotechnology.net". If any "retrotechnology.com" links fail, change ".com" to ".net".
