APPLE ProtoType / Engineering Sample for the Keyboard II M0487 Vintage 1990s NO Part Number NO Casting for ID and part number label!

    Early in the 90's my shop had the Fremont Unified School District contract for servicing the Apple computers.  We did hundreds of keyboard replacements!  Apple was just up the street from my shop and Apple shipped us 10 of these and asked us to report back on the durability.  Well these worked out very well.  I was just clearing up the warehouse and I found this one Prototype engineering sample left on the shelf!

    The production keyboards have the product information cast into the base of the keyboard,  or they have the label relief cast in to the base.  This is one of the pre-production engineering samples used to test prior to production. NO part number,  no casting outline.

      The production units were made in Malaysia ,  Taiwan,  and Mexico.  The production units have a casting relief for the part number and information sticker ,  the Mexico production units have the part number and information cast into the rear of the case. This engineering sample was produced in the Apple quick fab facility.

     To the guy that asked me to open it up to see if there are signatures cast into the plastic... Put in a bid! This is not a fab-prototype like my Mac case with the signatures inside.  This is an engineering sample.  These were the first produced to test out,  that's how I got these.

     Thank you for your questions,  Why do I still have it ?.... We installed 9 of the others we received,  and threw out the 10 pack box,  since this has no part number,  it just sat on the shelf in the plastic bag for the past 32 years.

  To the guys that said I just ripped the sticker off... Dude the production version has a casting relief for the label! 

Look :

       This engineering sample has no casting relief for the label, and no part number ID.
