Description

Object is a collection of integrated circuits and integrated circuit carriers in a box. The box was lined with highly suspect foam which has been removed and the ICs transferred to better packing materials. The collection consists of:
A metal carrier strip with 9 IC cases.
A metal carrier strip with 7 IC cases.
A metal carrier strip with 6 of what may be complete ICs, and a seventh similar one cut from a similar strip (none stamped with any identifying numbers).
A metal carrier strip with positions for 6 ICs but no IC or plastic material applied.
Six small surface-mount ICs loose, type A4707.
Six small surface-mount ICs type M5259.
Seven surface-mount ICs type M5257.
Four large ICs type 56X2191.
Three 16-pin ICs type MSM3764.
Three 28-pin ICs type M27128.
The box in which the collection was received, which may be original packaging for some part of the collection (but likely not the carrier strips).
