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

TL;DR

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?

 

[phyzguy]

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

DRAM memory cards

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

Thank you guys I really appreciate it.

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
