Main Topic: The OSI Challenger series of computers
At this point in the podcast run, we are still in the
late 1970 s time frame, and the OSI machines fall into
that time frame for their release. No vintage computer
historical journey would be complete without including
these very important machines. As usual, we ll cover the
history, technical specs, peripherals, Web sites, books,
emulation and much, much more. I am joined by special
guest host Terry Stewart of the Classic Computers website
who will help me cover these machines. In addition, we
are joined by OSI aficionados Mark Csele and David Fenyes
who share their first-hand memories of the OSI. But
first, I ll cover new acquisitions, news, and feedback
before diving into the OSI.
