Support Us

One core aspect of LSSM's mission is that it remain totally free. No one will be denied an experience here just because they don't have a few dollars in their pocket. That said, it does cost real money to run our museum, and these costs are borne by our volunteer staff, often from our own pockets. We do this as a labor of love. We request, but do not require, donations in the form of cash, checks, or electronically via PayPal.

Your donations make it possible for us to restore and maintain our systems, produce educational materials, scan and preserve technical documentation, and even, literally, to keep the lights on.

Our museum is has been designated a 501(c)(3) nonprofit organization under the name “Museum of Applied Computer Technology”. Donations may be tax-deductible depending on your tax situation. Ask your tax preparer. Email for additional information about our organization.

Checks may be made out to “Museum of Applied Computer Technology”; our mailing address is Large Scale Systems Museum, 924 4th Avenue, New Kensington, PA 15068. Our PayPal address is “”, or use the “Donate” button below.

To be clear, the museum is free, but donations are needed and appreciated.

Another way to support our museum is to purchase swag! We have great swag that is available through our Teespring shop. We hate cheap T-shirts as much as you do; we've selected only premium shirts for our LSSM swag!
