Note: Due to the massive increase in Royal Mail prices, from the 2nd October 2023 I have been forced to increase prices.

Price of 2nd Class Large Letter increasing to £1.55 (39% increase)

TMS4164-10NL DRAM 64k x 1 

Condition: Used. As these chips are long obsolete you will not find any 'new' chips. 

The RAM chips have been tested in a dedicated RAM tested and work 100%

Qty: 2

These chips are used in old retro computers like the Commodore 64, ZX Spectrum  (Upper RAM), Atari, Amstrad and others. 

I use these chips to repair Spectrums  and have not had any issues. 


You can also buy a DRAM tester for 4164 / 41256 chips which I build and sell here


Please contact me if you have any queries and I will be only too happy to answer them.
