The Signetics N82S29 is a 256bit x 4bit wide PROM with tri-state outputs. This package of 9 N82S29 ICs were obtained many years ago along with a collection of other chips that I use for repairing vintage computer boards. The description from the Signetics Handbook: "The 82S26 (open collector outputs) and the 82S29 (tri-state outputs) are bipolar 1024 bit Read only Memories organized as 256 words by 4 bits per word. They are Field Programmable, which means that custom patterns are immediately available by following  the simple fusing procedure given in this data sheet. Two chip enable lines are provided and the outputs are bussable to allow for memory expansion capability." These particular ICs came from a lot of ICs I bought as spare parts. Since I am not able to test them, they are being sold as collectors items. The photos show several views of two chips removed from the plastic holder and photographed on anti-static foam. Mailing will be via USPS First Class mail in the US, and International First Class mail for other countries.. Note: I normally mail the same or next day after receiving the PayPal notification.
Condition For parts or not working :
An item that does not function as intended and is not fully operational. This includes items that are defective in ways that render them difficult to use, items that require service or repair, or items missing essential components. See the seller’s listing for full details.
Seller Notes “They look like NOS (New Old Stock) but are being sold as collectors items since I am unable to test them.”
