Floppy Days Episode 27 - Ohio Scientific Challenger

Floppy Days Vintage Computing Podcast - Un pódcast de Randy Kindig

Categorías:

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.   Links Mentioned in the Show:   New Acquisitions/What I’ve Been up to TI-99 Extended BASIC Suite cartridge - http://www.ebay.com/itm/Extended-Basic-v2-7-Suite-Cartridge-/231378985072 Microsoft BASIC II for the Atari 8-bit - http://en.wikipedia.org/wiki/Atari_Microsoft_BASIC CoCo SDC SD Card Interface for the TRS-80 Color Computer - http://cocosdc.blogspot.com/   News CSDB intro competition - http://csdb.dk/event/?id=2286 Ben Heck’s Apple 1 Replica - https://www.youtube.com/playlist?list=PLwO8CTSLTkiiDKhVfiUXyuzfbHMPOYVPj VCF East 10.0 - http://www.vintage.org Donkey Kong Junior for C64 - http://csdb.dk/release/?id=134342 Another Apple-1 Goes for Auction - http://www.reuters.com/article/2014/11/03/us-auction-apple-idUSKBN0IN0ZX20141103 Atari: Game Over Movie - http://video.xbox.com/movie/atari-game-over/4B8575C6-BD05-48E8-92C9-C61BA57E8025 C64 Reset Magazine - http://reset.cbm8bit.com/   Ads COMPUTE!
