Honestly being into vintage/retro computers is already an accepted thing in geek spaces, both neurotypical and neurodivergent ones, and has been for years, so you really don't really need to worry about it.
Sure, there's always going to be people who don't get it, but even if you were NT and were interested in this same thing, they still wouldn't get it because they'd just think of these old computers as junk that should be recycled or thrown out.
Shame really, but who cares if people don't understand your interests, y'know?

Remember that it is never too late to accept God's love into your heart and to believe the truth that Jesus Christ died for your sins, was buried, and rose from the dead after three days. Christ's sacrifice was unconditional and it is never too late to invite Him into your heart as your personal Savior!
