Large (around 10 lbs) mixed lot of vintage ICs chips. Most of them appear to be 7400 series TTL ICs with a few other types mixed in. The date codes are mostly from the mid to late 1970's through the late 80's. The 10lbs weight represents the pieces alone; the pictured weight is the boxes, rails, small bags, and shipping box all together, which weigh about 3.8 lbs apart from the ICs.
There are 200 bags and 29 anti-static IC tube rails, I've estimated around 2000+ pieces of EPROM, logic, SRAM, and more from various manufacturers such as Texas Instruments, AMD, Philips, SGS, NEC, Toshiba, Motorola, On Semi, MA/COM, Fairchild, National Semi, Intel, PlesseySiemens, and several others. Please review all photos as they are part of the description. I'm happy to answer any questions you might have. These came from a closed repair shop that supported mostly military and aerospace test equipment.
