Stock of legacy semiconductor devices that may be useful for repair and maintenance of equipment - mainly PROMs in DIP housings

Various old stock from projects in the early 1990s. Mostly PROMs in DIP housings but some processors, RAM, programmable logic chips and serial controllers.
Some parts are new but others have been used in circuit boards and may also be programmed and have labels on them (all devices can be deleted and reprogrammed).
Descriptions of parts function are believed to be true but not guarantied - please check carefully!
Operation is not guarantied since they are not new parts and haven't been tested. They have however been stored in tubes or trays with ESD protection - if they could be of use it is advised to purchase a few spares to be sure.
