Straight from my "spare parts" section of my old workshop stores, these are NEW devices, but of course old stock
MOTOROLA - Special Function IC
Type: UC3842P
8 pin DIL plastic
Function: Current Mode PWM Controller
Full specifications/block diagrams/application notes are readily available online
COSMETIC CONDITION:

NO bent legs!
Light oxidisation to the legs, not brilliantly shiny any longer but just a slight dullness and still perfectly useable.
These have been stored in an ESD tube to protect the legs and will be supplied in the same type of packaging.
