Hello everyone:)

This is my first post here.

I managed to build one.
My next step was build PS/2 adapter and 64kB memory expander.
It working fine.

The memory expander looks neat!

I am quite partial, but you might find interesting to build a 128kb ram and IO extension,

then try to browse a sdcard attached to the spi bus,
viewtopic.php?t=332 .

Very nice, clean work. The white paint covers the conductor tracks, which immediately gives a different picture. Also very nice solution for the DAC (R9).
If you want to follow lb3361 recommendation, you can get a PCB from me.
