    Excellent design and functionality! PCB’s are always of great quality. This board will allow to expand conventional RAM all the way up to 640kb, and gives the ability to populate upper RAM area from A000h to EFFFh in 64KB increments via the dipswitch. Using a DOS driver it is possible to use the Upper RAM area to load drivers, and thus maximizing memory on XT systems.

    This board will be a little harder for people who might be newcomers to soldering, not so much because board is pretty much all SMD components, but because the the the SMD resistor arrays are a bit tricky to solder correctly.

    After using and building this cards myself i now trade them at amibay, for people who might want one but is put off but the required soldering:

    And best of all, if there is any problem James Pearce is a very helpful person and always keen to help solve any issues.

    5 stars to both store and product!!
