Are These for Retro Fans? Let's Find Out!

In summary, the conversation discusses identifying old DRAM memory cards and the possibility of recycling them. The speaker mentions working mostly with SRAMs but realizing that memory SIMMs would use DRAMs instead. They also suggest checking with retro fans before recycling as older hardware can be sought after. The numbers on the memory cards are likely package year and week date codes.

TL;DR Summary
I have found these old electronic parts in some forgotten electronics junk pile. And even though I can identify the individual parts I still can't know what they are used for together.

They look like memory SIMMs. What are the ICs that you say you have identified? SRAMs DRAMs maybe?

Yes, they are DRAM memory cards. Here's the description of the parts on the left. So the chips are 1 Meg DRAMs. So these are OLD. Recycle them if you can.
Part #: TC514256AJL-80
Part Category: Memory ICs
Manufacturer: Toshiba America Electronic Components, Inc.
Description: Fast Page DRAM, 256KX4, 80ns, CMOS, PDSO20

Yes, I'll correct my post. I work mostly with SRAMs, but memory SIMMs would use DRAMs. Duh! Thanks

Actually I would check first with retro fans, some older hardware is hard to find and sought after.

Several months ago I needed a plain vanilla old Pentium for a picture, took me several days to locate one.

The numbers 9020, 9024, 9025, and 9038 are probably a package year and week date code. 9020 = 20th week of 1990.

Great idea, will do.
Thanks
 

FAQ: Are These for Retro Fans? Let's Find Out!

What is the purpose of these experiments?

The purpose of these experiments is to test a hypothesis or answer a research question. By conducting experiments, scientists can gather data and evidence to support or refute their ideas.

Why is it important to understand the purpose of a study?

Understanding the purpose of a study helps to provide context and meaning to the results. It also allows other scientists to replicate or build upon the study, leading to further advancements in the field.

How do scientists determine the purpose of their research?

Scientists determine the purpose of their research by identifying a problem or gap in knowledge, formulating a hypothesis or research question, and designing experiments or studies to test their ideas.

Can the purpose of a study change during the research process?

Yes, the purpose of a study can change as scientists gather new data and information. This may lead to the modification of the original hypothesis or the discovery of new research questions.

What is the difference between the purpose and the objectives of a study?

The purpose of a study is the overall goal or reason for conducting the research, while the objectives are specific, measurable steps that are taken to achieve the purpose. Objectives help to guide the research process and provide a clear direction for the study.
