Despite its quirky hours, at times limited parking, and blink and you miss it signage, this is place is wonderful. Real history at the original location.
The equipment on display is “as they left it.” Lots you can touch and some you can use. The docents are knowledgeable and clearly enthused. The place has an appropriate musty odor and some of the labels are faded index cards. Real museum professionals will likely have an anxiety attack at the somewhat informal approach to display and preservation. (Nothing a small grant and an intern couldn’t help.)
It’s probably not best for small kids but I can attest that even non-nerds will come to like it.
