Listed at 17.00 USD. 251968-03 DOS ROM IC chip for 1541-II drives by CBM (Commodore Business Machines). Fifteen or twenty years ago we picked up many of these and other Commodore chips from a major corporation that used to refurbish Commodore computers. They came to us in factory-looking chip tubes. Most of the chips in the tubes had identical date production codes and the chip legs appeared to be very shiny and unbent which is typical for new chips. These particular chips may be pulls from used 1541-II drives although they look quite new. Some may have some very slightly bent legs. So, we assume they are new or at least in new-like condition. We picked up around ten thousand total Commodore and Amiga chips from this source and have sold thousands of them over the last 14 or 16 years with great success and very few problems. We ship these chips in special static-resistant chip boxes with black crisp anti-static foam to protect them. The photo shown may vary slightly from the actual chip you receive and the date production code may be different. These chips are in nice overall condition but may not be in mint condition due to the fact that they have been stored in chip tubes which may have scratched them slightly or caused other minor blemishes. We take note of the production date codes of all chips shipped and oftentimes put little warranty stickers on the bottom of the chips which we ship in order to make sure that any returns are chips which we actually sold. Any returned chips which do not match the production date codes or which have missing or damaged warranty stickers will not be refunded. If you don't want little warranty stickers on the bottom of these please contact us before ordering to make special arrangements. Note: Our shipping price is a couple of dollars higher than our actual shipping cost on these normally because of our cost on the special anti-static boxes which we ship them in. We have been selling Commodore hardware, parts and accessories for nearly 39 years (since 1983) and have a great reputation.
