Building a 4116 / 4164 DRAM testing kit

In this kit I build a 4116 / 4164 DRAM testing kit, suitable for ZX Spectrums Lower and Upper RAM tests, Commodore 64 plus many more retro computers.

I bought this kit from eBay - http://ebay.us/9iRtLs
but plenty of retro Computing shops now stock these kits. I hope this video helps you, I will find this kit very useful whilst i restore a stack of ZX Spectrum 48K models.
