Hi,

I plan to release new PCBs from the original Wilf Rigter's project.

XavSnap,

The board IVa design looks good. However, I would wait on you to design a High Speed Interface Va (Fifth a) with ALL "socketed" ICs out of the computers cases' way. Same concept as Timex Store Demo. board!

Thank you very much.

Hi DesSony,

I forgot to put the 3D edge BUS socket on the picture, but all cards are mounted as Memotechs standard. All component on the rear face (copper face).

However, i can rebuild the r4 using the safe case zone.
