512KB cache SRAM kit for 486 and Pentium machines.
Tested. Beware of fake SRAM.
I also have single SRAM ICs for sale, and can make up different kits.
This listing is for:
- 4 x 128K*8 15ns IC (DIP-32)
- 1 x 32K*8 12ns IC (DIP-28)
Your motherboard may need another a different combination of chips for 512KB.
Ask if you need different ICs and I can make up a custom kit for you (512K, 256K, etc).
Check your motherboard manual or TheRetroWeb for the required cache ICs and jumper settings.

eBay doesn't allow custom shipping service names.
"Economy" will be tracked airmail to most countries, but untracked to a few more remote ones. 1-2 weeks usually, but can take longer.
"Expedited" will be DHL Express. 3-4 days usually. Exact quotes vary depending on the country. I can refund if you are overcharged.
