Ohio Scientific Inc. – 50 year anniversary
This was one of the big anchor exhibits celebrating 50 years of OSI. They had borrowed an OSI-300 and original Challenger from Bill Sudbrink (who sadly could not attend this year), a second OSI-300 from Bill Dromgoole, and a Challenger 1P-MF and Challenger III from Crawford Griffith. An excellent array of OSI machines!
Hanging out with the Ohio Scientific fans at VCF East XXI was awesome. We had a collective 5 exhibits spanning 42ft of table space, celebrating the 50 year anniversary of a now-obscure, defunct company. Together, we covered most of the major milestones of OSI’s history, and the results were awesome.

I'll be exhibiting as part of the group of Ohio Scientific enthusiasts, showing off my OSI-400, Challenger 4P, and mini OSI-300 on Saturday & Sunday. You can come try out the game I've been programming for the past few months!
Stop on by, I'll have Retrotech Crew stickers to give away. Hope to see you there!
