Rare Heritage Computing Hardware: HP 9845 Series LPU Component Set. This is a comprehensive, nearly complete "brain" and "muscle" kit for a Hewlett-Packard 9845B/C workstation.

Condition: Every chip in this collection was professionally pulled directly from sockets (several are NOS). No desoldering tools or high-heat processes were used. This ensures the internal silicon dies and the original tin/gold plating on the pins have not been compromised by thermal stress.

The set is composed of the critical Language Processor Unit (LPU) components that are almost impossible to find individually.

Lot Highlights Include:

HP Proprietary ROMs: Includes the essential 0112-1101 series (12A, 13A, 14A, 15A, 16A) and the 0114-xxxx firmware series.

Technician Provenance: Many large chips feature original handwritten socket markings (3, 4, 5, 8, B, O, H) which are vital for period-correct restorations and correct board placement.

Matched ECL Logic Batch: Includes a full sequence of Fairchild 100102 DC and Signetics 100155 high-speed logic chips, essential for the 9845’s high-performance timing.

Communications & Memory: Includes SCN2661 controllers, F6856 protocol processors, and Fujitsu MBM2764 windowed EPROMs.

Date Codes: Primarily 1980–1983 (Golden Age of HP Computing).

Packaging: Majority are high-durability Ceramic DIP packages.

Shipping & Handling: Given the rarity of these components, they will be shipped in specialized anti-static foam and double-boxed to ensure they arrive in museum-grade condition.

Ideal for high-end collectors, institutional archives, or technicians performing museum-grade restorations of HP 9800 series hardware.
