 |
|
Sofar i found out about the logic gate chips, but these 4 chips I didn't get any info on.
This board is a computer or printer of some sort, maybe an electronic typewriter?
Also, hi im new here.
I think the MCM6064P12 is memory.

The two Signetics chips are both MCS-51 microcontrollers:
SCN8032HCCN40 is an Intel 8032 clone
SCN8052HCCN40 is an Intel 8052 clone

The 8052 was an enhanced version of the original Intel 8051 that featured 256 bytes of internal RAM instead of 128 bytes, 8 kB of ROM instead of 4 kB, and a third 16-bit timer. The 8032 had these same features except for the internal ROM program memory. The 8052 and 8032 are largely considered to be obsolete because these features and more are included in nearly all modern 8051 based microcontrollers.
So I Got 2 MC's One Ram And A Rom?
what can i do with them?

I think the Ram is a Motorola 8K x 8, Low power SRAM, 120ns access time. Motorola was not a major player in CMOS SRAMS as the Japanese quickly dominated the market. There is a spot on the PCB for SRAM memory backup battery. The RP chip might be a mask ROM for the same Signetics 8031 as the 8031 is romless, and that the SRAM and the Mask rom share the same 8031 Address and data lines. that the 373 latch is for address upper 8 address lines from the 8031. . I used to sell Signetics MCU's.
