David G.,
No. The board is big and won't fit inside the cased computer. However, it is possible to put some demo. program on the EPROMs/ EEPROMs and run it. Expect something coming from me pretty soon. Hopefully, a short video with a computer with its case in use. :) I still have 4 “fixed” long boards and 4 short boards ready to sell. Please understand that all the components on the long board will miss the cased computer. Some components on the short board will hit the cased computer. There are a few pictures of the board and the computer installed together here. :D

All of you, including XavSnap,

I put a new video on a YouTube. Please excuse my camera's autofocusing feature and my microphone shyness. Notice a red button on the right side of the computer case. The button is for reset control. All components, which were on the board, missed the edge of the computer case. Yay! It was successfully functioning! :-D

Thank you.

Cheers,

YouTube tells me that this Video ist private and doesn't Show it's content
In theory, there is no difference between theory and practice. But, in practice, there is.

Yes not everybody has or wants a YouTube account and why make it private?
It's a circuit board for a niche computer not a schematic of the guidance system for a S.A.M missile. :lol:

I am logged into my YouTube account, but I am still told the video is private. So I assume you have only given access to yourself.

My Apology. I almost overlooked about clicking a blank little circle “Public” and a blank little box “Set as instant Premiere” in a Schedule dialog. Sorry. I was puzzled and stunted! :o :? I will wait for it anyway to see what happen. If the problem persists, then I will ask YouTube for its support. :shock: Moggy is correct about the video's content.

Thanks.
