32121Re: The Demo setup for MARCH's Altair- current status
- Aug 18, 2013Agreed most early delivered Altairs didn't have a rom card or teletype interface, but its impractical for us to toggle in a demo every week when we open the museum. This way a few of us who know how to use the Altair can perform a reasonable procedure to be up and running. I'm trying to keep each machine down to minimum since there are more than a few in that room. This does not mean that just anyone can simply turn on the altair and get a demo running, but MARCH staff can.
