Up for sale is a rare, original lot of vintage mainframe/RJE terminal components manufactured by the Data 100 Corporation in the mid-1970s.


These parts were salvaged together and are being sold as a complete restoration lot for vintage computing hobbyists and archivists.



This lot includes a total of 7 distinct assemblies/pieces:


• Logic / IC Board (Part No. 81004540 A): Date stamped 7551 (51st week of 1975). Features dense TTL logic layout with ITT/Signetics chips. Gold edge fingers are clean.

• Backplane / Interconnect Motherboard: Passive bus distribution board mounted on its original heavy metal structural backing plate. Features 4 green multi-pin card edge socket banks.


• Sense-Amplifier / Core Memory Drivers: A complete matching fan stack of identical peripheral cards densely populated with gold-capped transistors and yellow axial capacitors.


• Wire-Wrap Prototype/Interface Card: Side profile photo displays the extensive gold-plated wire-wrap pins and complex blue point-to-point network wiring typical of mid-70s custom enterprise hardware configurations.



All items are in original, uncleaned vintage condition exactly as shown in the photos.


There are no obvious signs of burnt traces or catastrophic board failure, but due to their age (approx. 50 years old), everything is strictly sold AS-IS, untested for parts, repair, or historical archiving.


No original cables or chassis enclosures are included outside of what is pictured.
