Marlin Computer
From Spearfish Lake Tales Wiki
Marlin Computer is the business set up by Mark Gravengood when he leaves the telephone company in May 1990AF34. Mark had been tinkering with computers since the Altair 8008, and when the time came to leave the telephone company he turned his hobby into his job. The original shop had been a Pizza joint before.
Besides selling and repairing computers, Marlin also provided internet access for an area that included the towns of Spearfish Lake, Albany River and Warsaw. It held the DNS entry for marlin.com.
