A very rare, vintage IBM membrane keyboard!

The following description is not definitive, but I have researched it to the best of my knowledge.
* Made in 1996
* As you can see from the images, the printing has not faded at all even after nearly 30 years, indicating extremely durable printing. This highlights the high quality standards of IBM at the time.
* Steel backplate.
* Confirmed to be manufactured by the reputable Chicony (チコニー) based on the FCC ID (E8HKB-5923).

The key feel is more "clicky" and "crisp" rather than "soft". It may be a predecessor to the KB-3920 model.

I have confirmed that all keys are working using a key check software.
The "Print Screen" button works, but the color does not appear due to the software's characteristics. ※See photo.

This is a rare item that is not often found on the market.

I have wiped it down with alcohol before listing it.

A PS/2 connector will be included as a bonus.

Due to its age and being a used item, please understand that it is non-refundable and non-returnable.

It will be shipped in a cardboard box with cushioning material.

※Please refrain from purchasing if you are sensitive to scratches, stains, or age-related deterioration, as this is a used item.

Regarding transactions:
* I will only sell to those who have verified their identity.
* Those who can communicate clearly and understand each other.
* Those with good ratings.
I also request no returns or exchanges to prevent product substitution.

To prevent product sale disputes, I have taken photos of the packaging as evidence.
I will take legal action against those who make false claims such as "the product was not included" or "a different product was included."
