About this site
This site is a visual and written log of the punched cards I have collected. Most of it is IBM but there are things from companies long forgotten and probably never really known in the USA.
Most of this stuff came from that spawn of the devil, ebay.
One benefactor from England, Simon Barratt, more than doubled the size of the punch card collection for only the price of shipping. Thank you, Simon.
As of now (9/19/2024) I have been retired for 4199 days! People ask me what I am doing. Continue to update and maintain this site, of course!
The card collection is always being updated as I get new cards. The database currently has 5684 cards on display. While I admit there may be some true duplicates most of what appear to be duplicates are not. Corner type, cut location, manufacturer name location among others actually break the duplicate attribute.
