Demos

No long repair videos here. Just popular demos of our restored vintage equipment.

The first digital communication equipment, all electro-mechanical, in sturdy military guise. You'll be amazed at what this 1930's era hardware could do. No wonder it stayed in use until the 1980's.

We have many nice demos of our 1959 IBM 1401 mainframe compusaur in action.

The amazing 1959 computer that can display high res graphics, uses a pen, and plays music and video games.

The diminutive HP 85 is hooked to professional IT peripherals from the 1970s for seriously noisy ASCII art production.

The serious 1980 scientific calculator & lab test controller gets a little loose and draws art instead.

The genius machine that invented the modern personal computer, complete with a graphic user interface, a laser printer, and an Ethernet connection, from way earlier than you think.

The 1957 mechanical calculator that helped calculating orbits of the Mercury missions shows its mettle.
