Two microprocessor, 40 DIP IC, from AMI and Mostek for computer/video, vintage

I have done AI image analysis, and you can do further analysis on Google or whatever. As they are gold-plated, they can be used for recovering gold!!

Info from AI-image analyses
1. Integrated circuit in a ceramic DIP package from American Microsystems Inc (AMI).
Marked DEC part number 21-15542-01 (also known as 304E or part of the KTF11 chipset for Digital Equipment Corporation PDP-11 systems).
Circuit Information
• Manufacturer: AMI (American Microsystems Inc)
• Part Number / Marking: AMI 304E, DEC 21-15542-01
• Usage: Found in older Digital Equipment Corporation (DEC) computer equipment, including as part of the KTF11 chipset for the PDP-11.
Package: Ceramic DIP package (CDIP) with gold lid label and pins.

2. Mostek
An integrated circuit of the type Mostek MK3807P-4, manufactured week 38 of 1985.
About the component:
Manufacturer: Mostek
Model: MK3807P-4 (likely a variant of an F8 family or similar logic/support chip from the period)
Case: Black plastic or ceramic-like DIP case with a gold-colored metal or marking label and visible pins (legs) on the sides.
The circuit in the picture, Mostek MK3807P-4, is a so-called Video Attributes Controller / Video Timing Controller. It functions as a licensed variant ("second source") of the well-known SMC CRT 5037 display circuit.
During the late 1970s and 1980s, this type of circuit was primarily used to control video signals to CRT displays (thick screens) in early computer terminals, mainframe systems and measuring instruments.
