Large original collection of approximately 150+ vintage PROM, EPROM and memory ICs from older electronic/industrial equipment.
A particularly interesting engineering/firmware archive with numerous chips retaining their original handwritten and printed identification labels, revision numbers, position numbers, dates and other programming information.
Included are multiple related and sequential sets rather than simply a random assortment of loose ICs.
Notable examples visible in the collection include:
• Applied Materials / AMAT 0300-00025 numbered PROM/EPROM set
• Numerous Texas Instruments TMS-series UV EPROMs
• AMD EPROMs
• Intel-marked devices
• MMI / Monolithic Memories-type PROMs
• Multiple ceramic/windowed UV-erasable EPROMs
• Numerous sequentially numbered engineering/program sets
• Chips with revision, position, board and firmware-type identification labels
• Components dating primarily from the vintage 1970s/1980s electronics era
The 0300-00025 chips are especially noteworthy as this part-number family has been identified with Applied Materials semiconductor-processing equipment firmware/software.
These have NOT been electronically read, dumped, erased or otherwise tested. Original programmed contents, where present, are unknown.
All labels have intentionally been left intact.
Normal vintage cosmetic wear from age, storage and previous equipment use. Some labels show staining, fading or handwritten engineering notation.
Selling the entire collection together exactly as shown. I am not separating the programmed sets.
Excellent collection for vintage semiconductor collectors, semiconductor-equipment restoration, firmware preservation/recovery, electronics research, computer history or period IC collecting.
Please examine all photographs carefully for exact chip markings, labels, revisions and quantities.
