Hi guys, I have processed a lot of data to generate out my database of vintage SIMM and SIPP DRAM chips and modules:

This should be handy for those brewing at home 😀

This is awesome work, it'll save some time looking for chip part numbers etc., thänk you very much ~

In other news, I have a new batch available too.

Nice one! hope this helps. I've just sent my gerbers to PCB house. Quite curious if they gonna work 😀 These modules will need to be redesigned as I would like to put data and address on separate plains. how many layers have you used? Mine are 4 layers.

I like the logo 🤣

I just have two layers, there wasn't a need for more and it seems performance is up to task with even 50MHz FSB on a 486 machine without additional wait states etc.

Thanks, I will definitely redesign boards to only 2 layers, 4 layer PCB is super expensive and even just one stick works out about 50p (50 eurocents) and it's too much.
