if you restore, you know what they are.
let me know if your interested. i'll post quite a few.
first batch.

1. NEC H23141-211 / 8049C262Type: 8-bit Microcontroller (Intel MCS-48 family clone/variant).Manufacturer: NEC Corporation (Japan).Function: The 8049 series is an early 8-bit single-chip microcontroller with internal ROM and RAM, famously used in vintage keyboards (like the original IBM PC keyboard) and various electronic control instruments.
2. Intel P8031AHType: 8-bit Control-Oriented Microcontroller (MCS-51 architecture).Manufacturer: Intel Corporation.Function: Part of the legendary 8051 family. The 8031 variant specifically is a ROMless microcontroller, meaning it relies entirely on external memory for its program storage while using its internal 128 bytes of RAM. The "’82" stamp signifies its design or copyright lineage.
3. Motorola MCM6810P (Batch 8145)Type: 1024-bit Static RAM (SRAM).Manufacturer: Motorola.Function: A localized memory chip organized as 128 words by 8 bits (128 × 8). It was designed to run alongside first-generation 8-bit microprocessors like the Motorola 6800. The code 8145 indicates it was manufactured during week 45 of 1981.
4. Motorola MCM6810P (Batch 8201)Type: 1024-bit Static RAM (SRAM).Manufacturer: Motorola.Function: This is identical in function to the third chip. The code 8201 indicates it belongs to a different manufacturing batch, produced during week 1 of 1982.
