Hardware to run Home Assistant itself (Newbie question)?

I can’t get DesqView to run on my TRS-80, and I am having trouble copying HA on to the cassette I need to use. Would a 300 baud modem work (as long as nobody else picks up the phone)?

Just ran your question through a Herman Hollerith punch card on an IBM 704. You should have your answer in about a week.
