Original 1977 Apple Computer Part No. A2C024X — the 16K-16K-16K Memory Configuration Blocks, Set of 3, for the original Apple II (Rev 0 motherboard). This is the jumper block set that told the earliest Apple II machines their RAM was fully populated with 16K chips in all three rows — the "maxed out" 48K configuration. Apple sold this set for $10 in 1977; today it's a genuinely scarce piece of early Apple history, as later boards had the blocks soldered on and these loose sets mostly vanished.

Included:
- Original stamped Apple parts envelope, marked "Apple Part No. A2C024X / 16K-16K-16K Memory Configuration Blocks / Set of 3ea."
- Dealer provenance: envelope is stamped by The Show Room, 2527 University Ave., San Diego, CA — one of the very early Apple retail dealers
- Three black memory configuration jumper blocks
- Nine gray ceramic Intel DIP ICs marked "2036 202" with 1977 date codes (weeks 7719–7733), stored on anti-static foam, exactly as found with the set

Condition: Envelope shows honest age — creasing, wrinkles, and toning consistent with nearly 50 years, but the stamping is clearly legible. Blocks and ICs are untested and sold as collectible artifacts; sold as-is. Please review photos carefully, as they form part of the description.

A perfect display piece for an original Apple II restoration or any collection of early Apple ephemera. Items of this vintage with dealer-stamped packaging almost never survive.

Ships carefully packed, USPS Ground Advantage with tracking. No returns.
