This interface design is taken directly from the SCELBI Computer Digest, volume I, issue I. With the exception of the enclosure, it turns out that I had all the parts needed in my stash to build it. The dimension of the block of wood that I’m mounting this on, are set up such that it will be easy to move it into a Bud 3009-A enclosure. This is the enclosure in which most SCELBI peripherals are housed in.

It’s about ready to power up, but I’m wondering how much effort it will take to make it work. Unlike many people doing similar projects, I’m not real anxious to find out. More often that not, I’ve spent many hours trouble-shooting these kinds of designs before they could be made to work. Let’s just say that, at this point, I’m a little gun shy. I’ll most likely power it on tomorrow morning.
