A2386-PS2 - RAM Adapter
1997-07-28
## What's that? In the late 1990s when I bought a used A2386 Bridgeboard for my Amiga 4000, I felt angry that I should have to addinally buy expensive and aged ZIP ram for that card. For 2 mega bytes ZIP RAM I should pay 200 DM (~100 €) !!! ZIP DRAM where an old standard for dynamic RAM in the early 1990s:  I remembered having some old 1MB-PS2-Simms lying around and thought that it should be a possible to use them on my Bridgeboard with only a small adapter. The result of my thoughts and work was that little adapter which can be installed into the free ZIP sockets of the Commodore A2386 Bridgeboard. The adapter is able to provide 8MB RAM which is the official maximum - with a trick also to incredible 16MB! 😀 (This needs a BIOS-Update!) This is how the adapter looks like:  Plugged into the A2386 Commodore Bridgeboard the adapter looks like this: [](./img.jpg) ## Links The construction manual from 1997 is still downloadable from Aminet: [](http://aminet.net/search?query=A2386_PS2_V1.3)
