Electronic components, 3 pieces

Thank you for viewing.

This is a set of 3 electronic components.
① TC5504C-1 TOSHIBA - 1 piece
② 7400 7023 - 1 piece (There was writing that obscured the last digit, making it look like a 3.)
③ Socket - 1 piece (It appears to fit the TC5504C-1.)

Details such as manufacturer and specifications are unknown. These appear to be old ICs, LSIs, or sockets, but please forgive me if they are something else.
The model numbers were read from the products, but please forgive any misreadings.
Please refer to the ruler in the photo for size.

We cannot confirm operation, and as they have been stored for a long time, we cannot guarantee they will function correctly. Please consider them as collectible items.
There is no warranty regarding operation.

As we could not find a suitable listing category, we have listed them under Smartphones, Tablets, Computers > PC Parts, although they may not be PC parts.

Please purchase only if you understand and accept these conditions.
