2" Silicon Wafer Hewlett Packard Vintage HP 1E3C4C5C6C 9-1000 081E Failures Rare

Description

I have here an Extremely Rare 2" Hewlett Packard Silicon Wafer with codes 1E3C4C5C6C, 9-1000, and 081E.  I am assuming "081E" is some sort of Date Code with "81" being the year, but I am unsure.  I couldn't find any information on the other values either, but I will still be checking and update this listing as I go along.
This is definitely a nice wafer to have for any serious Silicon Wafer Collector!

Thank you for your time with viewing my listing, I appreciate it. I hope you have a great day!
NOTE:  Handling time is set to 10 days because I normally end up having buyers who want more than 1 item, so a few days can go by before the full transaction is completed; however, the handling time set for each item has to be obeyed or else penalties happen to me, so I set the handling time to a time that shouldn't cause problems.  I have been recently notified(10/24/22) that some buyers are concerned about the long handling times so I want to make everyone completely aware of the situation.
After THE FULL Transaction is complete(the buyer is done choosing listings to purchase, and ready for shipment), I normally try to ship the day of completion or the next day(depending if transaction completion happens early enough in the day and on a weekday), but 2-3 regular days(not business days) would be the maximum handling time.  I do not want buyers to have to wait for their product after purchase, I just want to make sure buyers have selected everything they want to purchase, before I ship, as most of my buyers thus far have wanted more than 1 item, while at the same time make sure I do not get penalized, because even if a buyer is okay with waiting, I have to obey the times set by the site.  Thank you for your understanding, and thank you for your time with viewing my listing, I really appreciate it.  If you have any questions at all about this issue, or anything else I can answer for you / help-you-with, please do not hesitate to ask.  I am here to make the Buyer's experience completely satisfactory, so let me know if there is anything I can do for you!  I hope you have a fantastic day!
